+
+ Devicetree (DT) ABI
+
+I. Regarding stable bindings/ABI, we quote from the 2013 ARM mini-summit
+ summary document:
+
+ "That still leaves the question of, what does a stable binding look
+ like? Certainly a stable binding means that a newer kernel will not
+ break on an older device tree, but that doesn't mean the binding is
+ frozen for all time. Grant said there are ways to change bindings that
+ don't result in breakage. For instance, if a new property is added,
+ then default to the previous behaviour if it is missing. If a binding
+ truly needs an incompatible change, then change the compatible string
+ at the same time. The driver can bind against both the old and the
+ new. These guidelines aren't new, but they desperately need to be
+ documented."
+
+II. General binding rules
+
+ 1) Maintainers, don't let perfect be the enemy of good. Don't hold up a
+ binding because it isn't perfect.
+
+ 2) Use specific compatible strings so that if we need to add a feature (DMA)
+ in the future, we can create a new compatible string. See I.
+
+ 3) Bindings can be augmented, but the driver shouldn't break when given
+ the old binding. ie. add additional properties, but don't change the
+ meaning of an existing property. For drivers, default to the original
+ behaviour when a newly added property is missing.
+
+ 4) Don't submit bindings for staging or unstable. That will be decided by
+ the devicetree maintainers *after* discussion on the mailinglist.
+
+III. Notes
+
+ 1) This document is intended as a general familiarization with the process as
+ decided at the 2013 Kernel Summit. When in doubt, the current word of the
+ devicetree maintainers overrules this document. In that situation, a patch
+ updating this document would be appreciated.

+* Renesas CPG Module Stop (MSTP) Clocks
+
+The CPG can gate SoC device clocks. The gates are organized in groups of up to
+32 gates.
+
+This device tree binding describes a single 32 gate clocks group per node.
+Clocks are referenced by user nodes by the MSTP node phandle and the clock

+ - "renesas,cpg-mstp-clock" for generic MSTP gate clocks
+ - reg: Base address and length of the I/O mapped registers used by the MSTP
+ clocks. The first register is the clock control register and is mandatory.
+ The second register is the clock status register and is optional when not
+ implemented in hardware.
+ - clocks: Reference to the parent clocks, one per output clock. The parents
+ must appear in the same order as the output clocks.
+ - #clock-cells: Must be 1
+ - clock-output-names: The name of the clocks as free-form strings

+Binding for TI divider clock
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped adjustable clock rate divider that does not gate and has
+only one input clock or parent. By default the value programmed into
+the register is one less than the actual divisor value. E.g:
+
+register value actual divisor value
+0 1
+1 2
+2 3
+
+This assumption may be modified by the following optional properties:
+
+ti,index-starts-at-one - valid divisor values start at 1, not the default
+of 0. E.g:
+register value actual divisor value
+1 1
+2 2
+3 3
+
+ti,index-power-of-two - valid divisor values are powers of two. E.g:
+register value actual divisor value
+0 1
+1 2
+2 4
+
+Additionally an array of valid dividers may be supplied like so:
+
+ ti,dividers = <4>, <8>, <0>, <16>;
+
+Which will map the resulting values to a divisor table by their index:
+register value actual divisor value
+0 4
+1 8
+2 <invalid divisor, skipped>
+3 16
+
+Any zero value in this array means the corresponding bit-value is invalid
+and must not be used.
+
+The binding must also provide the register to control the divider and
+unless the divider array is provided, min and max dividers. Optionally
+the number of bits to shift that mask, if necessary. If the shift value
+is missing it is the same as supplying a zero shift.
+
+This binding can also optionally provide support to the hardware autoidle
+feature, see [2].

+Binding for TI mux clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped multiplexer with multiple input clock signals or
+parents, one of which can be selected as output. This clock does not
+gate or adjust the parent rate via a divider or multiplier.
+
+By default the "clocks" property lists the parents in the same order
+as they are programmed into the regster. E.g:
+
+ clocks = <&foo_clock>, <&bar_clock>, <&baz_clock>;
+
+results in programming the register as follows:
+
+register value selected parent clock
+0 foo_clock
+1 bar_clock
+2 baz_clock
+
+Some clock controller IPs do not allow a value of zero to be programmed
+into the register, instead indexing begins at 1. The optional property
+"index-starts-at-one" modified the scheme as follows:
+
+register value selected clock parent
+1 foo_clock
+2 bar_clock
+3 baz_clock
+
+The binding must provide the register to control the mux. Optionally
+the number of bits to shift the control field in the register can be
+supplied. If the shift value is missing it is the same as supplying
+a zero shift.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be "ti,mux-clock" or "ti,composite-mux-clock".
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of parent clocks
+- reg : register offset for register controlling adjustable mux
+
+Optional properties:
+- ti,bit-shift : number of bits to shift the bit-mask, defaults to
+ 0 if not present
+- ti,index-starts-at-one : valid input select programming starts at 1, not
+ zero
+- ti,set-rate-parent : clk_set_rate is propagated to parent clock,

+MIPI DSI (Display Serial Interface) busses
+==========================================
+
+The MIPI Display Serial Interface specifies a serial bus and a protocol for
+communication between a host and up to four peripherals. This document will
+define the syntax used to represent a DSI bus in a device tree.
+
+This document describes DSI bus-specific properties only or defines existing
+standard properties in the context of the DSI bus.
+
+Each DSI host provides a DSI bus. The DSI host controller's node contains a
+set of properties that characterize the bus. Child nodes describe individual
+peripherals on that bus.
+
+The following assumes that only a single peripheral is connected to a DSI
+host. Experience shows that this is true for the large majority of setups.
+
+DSI host
+--------
+
+In addition to the standard properties and those defined by the parent bus of
+a DSI host, the following properties apply to a node representing a DSI host.
+
+Required properties:
+- #address-cells: The number of cells required to represent an address on the
+ bus. DSI peripherals are addressed using a 2-bit virtual channel number, so
+ a maximum of 4 devices can be addressed on a single bus. Hence the value of
+ this property should be 1.
+- #size-cells: Should be 0. There are cases where it makes sense to use a
+ different value here. See below.
+
+DSI peripheral
+--------------
+
+Peripherals are represented as child nodes of the DSI host's node. Properties
+described here apply to all DSI peripherals, but individual bindings may want
+to define additional, device-specific properties.
+
+Required properties:
+- reg: The virtual channel number of a DSI peripheral. Must be in the range
+ from 0 to 3.
+
+Some DSI peripherals respond to more than a single virtual channel. In that
+case two alternative representations can be chosen:
+- The reg property can take multiple entries, one for each virtual channel
+ that the peripheral responds to.
+- If the virtual channels that a peripheral responds to are consecutive, the
+ #size-cells can be set to 1. The first cell of each entry in the reg
+ property is the number of the first virtual channel and the second cell is
+ the number of consecutive virtual channels.
+
+Example
+-------
+
+ dsi-host {
+ ...
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ /* peripheral responds to virtual channel 0 */
+ peripheral@0 {
+ compatible = "...";
+ reg = <0>;
+ };
+
+ ...
+ };
+
+ dsi-host {
+ ...
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ /* peripheral responds to virtual channels 0 and 2 */
+ peripheral@0 {
+ compatible = "...";
+ reg = <0, 2>;
+ };
+
+ ...
+ };
+
+ dsi-host {
+ ...
+
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ /* peripheral responds to virtual channels 1, 2 and 3 */
+ peripheral@1 {
+ compatible = "...";
+ reg = <1 3>;
+ };
+
+ ...
+ };

+BCM11130, BCM11140, BCM11351, BCM28145, and BCM28155 SoCs.
+
+=== Pin Controller Node ===
+
+Required Properties:
+
+- compatible: Must be "brcm,capri-pinctrl".
+- reg: Base address of the PAD Controller register block and the size
+ of the block.
+
+For example, the following is the bare minimum node:
+
+ pinctrl@35004800 {
+ compatible = "brcm,capri-pinctrl";
+ reg = <0x35004800 0x430>;
+ };
+
+As a pin controller device, in addition to the required properties, this node
+should also contain the pin configuration nodes that client devices reference,
+if any.
+
+=== Pin Configuration Node ===
+
+Each pin configuration node is a sub-node of the pin controller node and is a
+container of an arbitrary number of subnodes, called pin group nodes in this
+document.
+
+Please refer to the pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the definition of a
+"pin configuration node".
+
+=== Pin Group Node ===
+
+A pin group node specifies the desired pin mux and/or pin configuration for an
+arbitrary number of pins. The name of the pin group node is optional and not
+used.
+
+A pin group node only affects the properties specified in the node, and has no
+effect on any properties that are omitted.
+
+The pin group node accepts a subset of the generic pin config properties. For
+details generic pin config properties, please refer to pinctrl-bindings.txt
+and <include/linux/pinctrl/pinconfig-generic.h>.
+
+Each pin controlled by this pin controller belong to one of three types:
+Standard, I2C, and HDMI. Each type accepts a different set of pin config
+properties. A list of pins and their types is provided below.
+
+Required Properties (applicable to all pins):
+
+- pins: Multiple strings. Specifies the name(s) of one or more pins to
+ be configured by this node.
+
+Optional Properties (for standard pins):
+
+- function: String. Specifies the pin mux selection. Values
+ must be one of: "alt1", "alt2", "alt3", "alt4"
+- input-schmitt-enable: No arguments. Enable schmitt-trigger mode.
+- input-schmitt-disable: No arguments. Disable schmitt-trigger mode.
+- bias-pull-up: No arguments. Pull up on pin.
+- bias-pull-down: No arguments. Pull down on pin.
+- bias-disable: No arguments. Disable pin bias.
+- slew-rate: Integer. Meaning depends on configured pin mux:
+ *_SCL or *_SDA:
+ 0: Standard(100kbps)& Fast(400kbps) mode
+ 1: Highspeed (3.4Mbps) mode
+ IC_DM or IC_DP:
+ 0: normal slew rate
+ 1: fast slew rate
+ Otherwise:
+ 0: fast slew rate
+ 1: normal slew rate
+- input-enable: No arguements. Enable input (does not affect
+ output.)
+- input-disable: No arguements. Disable input (does not affect
+ output.)
+- drive-strength: Integer. Drive strength in mA. Valid values are
+ 2, 4, 6, 8, 10, 12, 14, 16 mA.
+
+Optional Properties (for I2C pins):
+
+- function: String. Specifies the pin mux selection. Values
+ must be one of: "alt1", "alt2", "alt3", "alt4"
+- bias-pull-up: Integer. Pull up strength in Ohm. There are 3
+ pull-up resisitors (1.2k, 1.8k, 2.7k) available
+ in parallel for I2C pins, so the valid values
+ are: 568, 720, 831, 1080, 1200, 1800, 2700 Ohm.
+- bias-disable: No arguments. Disable pin bias.
+- slew-rate: Integer. Meaning depends on configured pin mux:
+ *_SCL or *_SDA:
+ 0: Standard(100kbps)& Fast(400kbps) mode
+ 1: Highspeed (3.4Mbps) mode
+ IC_DM or IC_DP:
+ 0: normal slew rate
+ 1: fast slew rate
+ Otherwise:
+ 0: fast slew rate
+ 1: normal slew rate
+- input-enable: No arguements. Enable input (does not affect
+ output.)
+- input-disable: No arguements. Disable input (does not affect
+ output.)
+
+Optional Properties (for HDMI pins):
+
+- function: String. Specifies the pin mux selection. Values
+ must be one of: "alt1", "alt2", "alt3", "alt4"
+- slew-rate: Integer. Controls slew rate.
+ 0: Standard(100kbps)& Fast(400kbps) mode
+ 1: Highspeed (3.4Mbps) mode
+- input-enable: No arguements. Enable input (does not affect
+ output.)
+- input-disable: No arguements. Disable input (does not affect
+ output.)
+
+Example:
+// pin controller node
+pinctrl@35004800 {
+ compatible = "brcm,capri-pinctrl";
+ reg = <0x35004800 0x430>;
+
+ // pin configuration node
+ dev_a_default: dev_a_active {
+ //group node defining 1 standard pin
+ grp_1 {
+ pins = "std_pin1";
+ function = "alt1";
+ input-schmitt-enable;
+ bias-disable;
+ slew-rate = <1>;
+ drive-strength = <4>;
+ };
+
+ // group node defining 2 I2C pins
+ grp_2 {
+ pins = "i2c_pin1", "i2c_pin2";
+ function = "alt2";
+ bias-pull-up = <720>;
+ input-enable;
+ };
+
+ // group node defining 2 HDMI pins
+ grp_3 {
+ pins = "hdmi_pin1", "hdmi_pin2";
+ function = "alt3";
+ slew-rate = <1>;
+ };
+
+ // other pin group nodes
+ ...
+ };
+
+ // other pin configuration nodes
+ ...
+};
+
+In the example above, "dev_a_active" is a pin configuration node with a number
+of sub-nodes. In the pin group node "grp_1", one pin, "std_pin1", is defined in
+the "pins" property. Thus, the remaining properties in the "grp_1" node applies
+only to this pin, including the following settings:
+ - setting pinmux to "alt1"
+ - enabling schmitt-trigger (hystersis) mode
+ - disabling pin bias
+ - setting the slew-rate to 1
+ - setting the drive strength to 4 mA
+Note that neither "input-enable" nor "input-disable" was specified - the pinctrl
+subsystem will therefore leave this property unchanged from whatever state it
+was in before applying these changes.
+
+The "pins" property in the pin group node "grp_2" specifies two pins -
+"i2c_pin1" and "i2c_pin2"; the remaining properties in this pin group node,
+therefore, applies to both of these pins. The properties include:
+ - setting pinmux to "alt2"
+ - setting pull-up resistance to 720 Ohm (ie. enabling 1.2k and 1.8k resistors
+ in parallel)
+ - enabling both pins' input
+"slew-rate" is not specified in this pin group node, so the slew-rate for these
+pins are left as-is.
+
+Finally, "grp_3" defines two HDMI pins. The following properties are applied to
+both pins:
+ - setting pinmux to "alt3"
+ - setting slew-rate to 1; for HDMI pins, this corresponds to the 3.4 Mbps
+ Highspeed mode
+The input is neither enabled or disabled, and is left untouched.

+The Tegra124 pinctrl binding is very similar to the Tegra20 and Tegra30
+pinctrl binding, as described in nvidia,tegra20-pinmux.txt and
+nvidia,tegra30-pinmux.txt. In fact, this document assumes that binding as
+a baseline, and only documents the differences between the two bindings.
+
+Required properties:
+- compatible: "nvidia,tegra124-pinmux"
+- reg: Should contain a list of base address and size pairs for:
+ -- first entry - the drive strength and pad control registers.
+ -- second entry - the pinmux registers
+
+Tegra124 adds the following optional properties for pin configuration subnodes.
+The macros for options are defined in the
+ include/dt-binding/pinctrl/pinctrl-tegra.h.
+- nvidia,enable-input: Integer. Enable the pin's input path.

+Qualcomm MSM8974 TLMM block
+
+Required properties:
+- compatible: "qcom,msm8x74-pinctrl"
+- reg: Should be the base address and length of the TLMM block.
+- interrupts: Should be the parent IRQ of the TLMM block.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Should be two.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two.
+ The first cell is the gpio pin number and the
+ second cell is used for optional parameters.
+
+Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
+a general description of GPIO and interrupt bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Qualcomm's pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+ pins, function, bias-disable, bias-pull-down, bias-pull,up, drive-strength.
+
+Non-empty subnodes must specify the 'pins' property.
+Note that not all properties are valid for all pins.
+
+
+Valid values for qcom,pins are:
+ gpio0-gpio145
+ Supports mux, bias and drive-strength
+
+ sdc1_clk, sdc1_cmd, sdc1_data, sdc2_clk, sdc2_cmd, sdc2_data
+ Supports bias and drive-strength
+
+Valid values for qcom,function are:
+ blsp_i2c2, blsp_i2c6, blsp_i2c11, blsp_spi1, blsp_uart2, blsp_uart8, slimbus
+
+ (Note that this is not yet the complete list of functions)
+
+
+
+Example:
+
+ msmgpio: pinctrl@fd510000 {
+ compatible = "qcom,msm8974-pinctrl";
+ reg = <0xfd510000 0x4000>;

+Freescale Enhanced Serial Audio Interface (ESAI) Controller
+
+The Enhanced Serial Audio Interface (ESAI) provides a full-duplex serial port
+for serial communication with a variety of serial devices, including industry
+standard codecs, Sony/Phillips Digital Interface (S/PDIF) transceivers, and
+other DSPs. It has up to six transmitters and four receivers.
+
+Required properties:
+
+ - compatible : Compatible list, must contain "fsl,imx35-esai".
+
+ - reg : Offset and length of the register set for the device.
+
+ - interrupts : Contains the spdif interrupt.
+
+ - dmas : Generic dma devicetree binding as described in
+ Documentation/devicetree/bindings/dma/dma.txt.
+
+ - dma-names : Two dmas have to be defined, "tx" and "rx".
+
+ - clocks: Contains an entry for each entry in clock-names.
+
+ - clock-names : Includes the following entries:
+ "core" The core clock used to access registers
+ "extal" The esai baud clock for esai controller used to derive
+ HCK, SCK and FS.
+ "fsys" The system clock derived from ahb clock used to derive
+ HCK, SCK and FS.
+
+ - fsl,fifo-depth: The number of elements in the transmit and receive FIFOs.
+ This number is the maximum allowed value for TFCR[TFWM] or RFCR[RFWM].
+
+ - fsl,esai-synchronous: This is a boolean property. If present, indicating
+ that ESAI would work in the synchronous mode, which means all the settings
+ for Receiving would be duplicated from Transmition related registers.
+
+Example:

+* Thermal Framework Device Tree descriptor
+
+This file describes a generic binding to provide a way of
+defining hardware thermal structure using device tree.
+A thermal structure includes thermal zones and their components,
+such as trip points, polling intervals, sensors and cooling devices
+binding descriptors.
+
+The target of device tree thermal descriptors is to describe only
+the hardware thermal aspects. The thermal device tree bindings are
+not about how the system must control or which algorithm or policy
+must be taken in place.
+
+There are five types of nodes involved to describe thermal bindings:
+- thermal sensors: devices which may be used to take temperature
+ measurements.
+- cooling devices: devices which may be used to dissipate heat.
+- trip points: describe key temperatures at which cooling is recommended. The
+ set of points should be chosen based on hardware limits.
+- cooling maps: used to describe links between trip points and cooling devices;
+- thermal zones: used to describe thermal data within the hardware;
+
+The following is a description of each of these node types.
+
+* Thermal sensor devices
+
+Thermal sensor devices are nodes providing temperature sensing capabilities on
+thermal zones. Typical devices are I2C ADC converters and bandgaps. These are
+nodes providing temperature data to thermal zones. Thermal sensor devices may
+control one or more internal sensors.
+
+Required property:
+- #thermal-sensor-cells: Used to provide sensor device specific information
+ Type: unsigned while referring to it. Typically 0 on thermal sensor
+ Size: one cell nodes with only one sensor, and at least 1 on nodes
+ with several internal sensors, in order
+ to identify uniquely the sensor instances within
+ the IC. See thermal zone binding for more details
+ on how consumers refer to sensor devices.
+
+* Cooling device nodes
+
+Cooling devices are nodes providing control on power dissipation. There
+are essentially two ways to provide control on power dissipation. First
+is by means of regulating device performance, which is known as passive
+cooling. A typical passive cooling is a CPU that has dynamic voltage and
+frequency scaling (DVFS), and uses lower frequencies as cooling states.
+Second is by means of activating devices in order to remove
+the dissipated heat, which is known as active cooling, e.g. regulating
+fan speeds. In both cases, cooling devices shall have a way to determine
+the state of cooling in which the device is.
+
+Any cooling device has a range of cooling states (i.e. different levels
+of heat dissipation). For example a fan's cooling states correspond to
+the different fan speeds possible. Cooling states are referred to by
+single unsigned integers, where larger numbers mean greater heat
+dissipation. The precise set of cooling states associated with a device
+(as referred to be the cooling-min-state and cooling-max-state
+properties) should be defined in a particular device's binding.
+For more examples of cooling devices, refer to the example sections below.
+
+Required properties:
+- cooling-min-state: An integer indicating the smallest
+ Type: unsigned cooling state accepted. Typically 0.
+ Size: one cell
+
+- cooling-max-state: An integer indicating the largest
+ Type: unsigned cooling state accepted.
+ Size: one cell
+
+- #cooling-cells: Used to provide cooling device specific information
+ Type: unsigned while referring to it. Must be at least 2, in order
+ Size: one cell to specify minimum and maximum cooling state used
+ in the reference. The first cell is the minimum
+ cooling state requested and the second cell is
+ the maximum cooling state requested in the reference.
+ See Cooling device maps section below for more details
+ on how consumers refer to cooling devices.
+
+* Trip points
+
+The trip node is a node to describe a point in the temperature domain
+in which the system takes an action. This node describes just the point,
+not the action.
+
+Required properties:
+- temperature: An integer indicating the trip temperature level,
+ Type: signed in millicelsius.
+ Size: one cell
+
+- hysteresis: A low hysteresis value on temperature property (above).
+ Type: unsigned This is a relative value, in millicelsius.
+ Size: one cell
+
+- type: a string containing the trip type. Expected values are:
+ "active": A trip point to enable active cooling
+ "passive": A trip point to enable passive cooling
+ "hot": A trip point to notify emergency
+ "critical": Hardware not reliable.
+ Type: string
+
+* Cooling device maps
+
+The cooling device maps node is a node to describe how cooling devices
+get assigned to trip points of the zone. The cooling devices are expected
+to be loaded in the target system.
+
+Required properties:
+- cooling-device: A phandle of a cooling device with its specifier,
+ Type: phandle + referring to which cooling device is used in this
+ cooling specifier binding. In the cooling specifier, the first cell
+ is the minimum cooling state and the second cell
+ is the maximum cooling state used in this map.
+- trip: A phandle of a trip point node within the same thermal
+ Type: phandle of zone.
+ trip point node
+
+Optional property:
+- contribution: The cooling contribution to the thermal zone of the
+ Type: unsigned referred cooling device at the referred trip point.
+ Size: one cell The contribution is a ratio of the sum
+ of all cooling contributions within a thermal zone.
+
+Note: Using the THERMAL_NO_LIMIT (-1UL) constant in the cooling-device phandle
+limit specifier means:
+(i) - minimum state allowed for minimum cooling state used in the reference.
+(ii) - maximum state allowed for maximum cooling state used in the reference.
+Refer to include/dt-bindings/thermal/thermal.h for definition of this constant.
+
+* Thermal zone nodes
+
+The thermal zone node is the node containing all the required info
+for describing a thermal zone, including its cooling device bindings. The
+thermal zone node must contain, apart from its own properties, one sub-node
+containing trip nodes and one sub-node containing all the zone cooling maps.
+
+Required properties:
+- polling-delay: The maximum number of milliseconds to wait between polls
+ Type: unsigned when checking this thermal zone.
+ Size: one cell
+
+- polling-delay-passive: The maximum number of milliseconds to wait
+ Type: unsigned between polls when performing passive cooling.
+ Size: one cell
+
+- thermal-sensors: A list of thermal sensor phandles and sensor specifier
+ Type: list of used while monitoring the thermal zone.
+ phandles + sensor
+ specifier
+
+- trips: A sub-node which is a container of only trip point nodes
+ Type: sub-node required to describe the thermal zone.
+
+- cooling-maps: A sub-node which is a container of only cooling device
+ Type: sub-node map nodes, used to describe the relation between trips
+ and cooling devices.
+
+Optional property:
+- coefficients: An array of integers (one signed cell) containing
+ Type: array coefficients to compose a linear relation between
+ Elem size: one cell the sensors listed in the thermal-sensors property.
+ Elem type: signed Coefficients defaults to 1, in case this property
+ is not specified. A simple linear polynomial is used:
+ Z = c0 * x0 + c1 + x1 + ... + c(n-1) * x(n-1) + cn.
+
+ The coefficients are ordered and they match with sensors
+ by means of sensor ID. Additional coefficients are
+ interpreted as constant offset.
+
+Note: The delay properties are bound to the maximum dT/dt (temperature
+derivative over time) in two situations for a thermal zone:
+(i) - when passive cooling is activated (polling-delay-passive); and
+(ii) - when the zone just needs to be monitored (polling-delay) or
+when active cooling is activated.
+
+The maximum dT/dt is highly bound to hardware power consumption and dissipation
+capability. The delays should be chosen to account for said max dT/dt,
+such that a device does not cross several trip boundaries unexpectedly
+between polls. Choosing the right polling delays shall avoid having the
+device in temperature ranges that may damage the silicon structures and
+reduce silicon lifetime.
+
+* The thermal-zones node

+The "thermal-zones" node is a container for all thermal zone nodes. It shall
+contain only sub-nodes describing thermal zones as in the section
+"Thermal zone nodes". The "thermal-zones" node appears under "/".
+
+* Examples
+
+Below are several examples on how to use thermal data descriptors
+using device tree bindings:
+
+(a) - CPU thermal zone
+
+The CPU thermal zone example below describes how to setup one thermal zone
+using one single sensor as temperature source and many cooling devices and
+power dissipation control sources.
+
+#include <dt-bindings/thermal/thermal.h>
+
+cpus {
+ /*
+ * Here is an example of describing a cooling device for a DVFS
+ * capable CPU. The CPU node describes its four OPPs.
+ * The cooling states possible are 0..3, and they are
+ * used as OPP indexes. The minimum cooling state is 0, which means
+ * all four OPPs can be available to the system. The maximum
+ * cooling state is 3, which means only the lowest OPPs (198MHz@0.85V)
+ * can be available in the system.
+ */
+ cpu0: cpu@0 {
+ ...
+ operating-points = <
+ /* kHz uV */
+ 970000 1200000
+ 792000 1100000
+ 396000 950000
+ 198000 850000
+ >;
+ cooling-min-state = <0>;
+ cooling-max-state = <3>;
+ #cooling-cells = <2>; /* min followed by max */
+ };
+ ...
+};
+
+&i2c1 {
+ ...
+ /*
+ * A simple fan controller which supports 10 speeds of operation
+ * (represented as 0-9).
+ */
+ fan0: fan@0x48 {
+ ...
+ cooling-min-state = <0>;
+ cooling-max-state = <9>;
+ #cooling-cells = <2>; /* min followed by max */
+ };
+};
+
+ocp {
+ ...
+ /*
+ * A simple IC with a single bandgap temperature sensor.
+ */
+ bandgap0: bandgap@0x0000ED00 {
+ ...
+ #thermal-sensor-cells = <0>;
+ };
+};
+
+thermal-zones {
+ cpu-thermal: cpu-thermal {
+ polling-delay-passive = <250>; /* milliseconds */
+ polling-delay = <1000>; /* milliseconds */
+
+ thermal-sensors = <&bandgap0>;
+
+ trips {
+ cpu-alert0: cpu-alert {
+ temperature = <90000>; /* millicelsius */
+ hysteresis = <2000>; /* millicelsius */
+ type = "active";
+ };
+ cpu-alert1: cpu-alert {
+ temperature = <100000>; /* millicelsius */
+ hysteresis = <2000>; /* millicelsius */
+ type = "passive";
+ };
+ cpu-crit: cpu-crit {
+ temperature = <125000>; /* millicelsius */
+ hysteresis = <2000>; /* millicelsius */
+ type = "critical";
+ };
+ };
+
+ cooling-maps {
+ map0 {
+ trip = <&cpu-alert0>;
+ cooling-device = <&fan0 THERMAL_NO_LIMITS 4>;
+ };
+ map1 {
+ trip = <&cpu-alert1>;
+ cooling-device = <&fan0 5 THERMAL_NO_LIMITS>;
+ };
+ map2 {
+ trip = <&cpu-alert1>;
+ cooling-device =
+ <&cpu0 THERMAL_NO_LIMITS THERMAL_NO_LIMITS>;
+ };
+ };
+ };
+};
+
+In the example above, the ADC sensor (bandgap0) at address 0x0000ED00 is
+used to monitor the zone 'cpu-thermal' using its sole sensor. A fan
+device (fan0) is controlled via I2C bus 1, at address 0x48, and has ten
+different cooling states 0-9. It is used to remove the heat out of
+the thermal zone 'cpu-thermal' using its cooling states
+from its minimum to 4, when it reaches trip point 'cpu-alert0'
+at 90C, as an example of active cooling. The same cooling device is used at
+'cpu-alert1', but from 5 to its maximum state. The cpu@0 device is also
+linked to the same thermal zone, 'cpu-thermal', as a passive cooling device,
+using all its cooling states at trip point 'cpu-alert1',
+which is a trip point at 100C. On the thermal zone 'cpu-thermal', at the
+temperature of 125C, represented by the trip point 'cpu-crit', the silicon
+is not reliable anymore.
+
+(b) - IC with several internal sensors
+
+The example below describes how to deploy several thermal zones based off a
+single sensor IC, assuming it has several internal sensors. This is a common
+case on SoC designs with several internal IPs that may need different thermal
+requirements, and thus may have their own sensor to monitor or detect internal
+hotspots in their silicon.
+
+#include <dt-bindings/thermal/thermal.h>
+
+ocp {
+ ...
+ /*
+ * A simple IC with several bandgap temperature sensors.
+ */
+ bandgap0: bandgap@0x0000ED00 {
+ ...
+ #thermal-sensor-cells = <1>;
+ };
+};
+
+thermal-zones {
+ cpu-thermal: cpu-thermal {
+ polling-delay-passive = <250>; /* milliseconds */
+ polling-delay = <1000>; /* milliseconds */
+
+ /* sensor ID */
+ thermal-sensors = <&bandgap0 0>;
+
+ trips {
+ /* each zone within the SoC may have its own trips */
+ cpu-alert: cpu-alert {
+ temperature = <100000>; /* millicelsius */
+ hysteresis = <2000>; /* millicelsius */
+ type = "passive";
+ };
+ cpu-crit: cpu-crit {
+ temperature = <125000>; /* millicelsius */
+ hysteresis = <2000>; /* millicelsius */
+ type = "critical";
+ };
+ };
+
+ cooling-maps {
+ /* each zone within the SoC may have its own cooling */
+ ...
+ };
+ };
+
+ gpu-thermal: gpu-thermal {
+ polling-delay-passive = <120>; /* milliseconds */
+ polling-delay = <1000>; /* milliseconds */
+
+ /* sensor ID */
+ thermal-sensors = <&bandgap0 1>;
+
+ trips {
+ /* each zone within the SoC may have its own trips */
+ gpu-alert: gpu-alert {
+ temperature = <90000>; /* millicelsius */
+ hysteresis = <2000>; /* millicelsius */
+ type = "passive";
+ };
+ gpu-crit: gpu-crit {
+ temperature = <105000>; /* millicelsius */
+ hysteresis = <2000>; /* millicelsius */
+ type = "critical";
+ };
+ };
+
+ cooling-maps {
+ /* each zone within the SoC may have its own cooling */
+ ...
+ };
+ };
+
+ dsp-thermal: dsp-thermal {
+ polling-delay-passive = <50>; /* milliseconds */
+ polling-delay = <1000>; /* milliseconds */
+
+ /* sensor ID */
+ thermal-sensors = <&bandgap0 2>;
+
+ trips {
+ /* each zone within the SoC may have its own trips */
+ dsp-alert: gpu-alert {
+ temperature = <90000>; /* millicelsius */
+ hysteresis = <2000>; /* millicelsius */
+ type = "passive";
+ };
+ dsp-crit: gpu-crit {
+ temperature = <135000>; /* millicelsius */
+ hysteresis = <2000>; /* millicelsius */
+ type = "critical";
+ };
+ };
+
+ cooling-maps {
+ /* each zone within the SoC may have its own cooling */
+ ...
+ };
+ };
+};
+
+In the example above, there is one bandgap IC which has the capability to
+monitor three sensors. The hardware has been designed so that sensors are
+placed on different places in the DIE to monitor different temperature
+hotspots: one for CPU thermal zone, one for GPU thermal zone and the
+other to monitor a DSP thermal zone.
+
+Thus, there is a need to assign each sensor provided by the bandgap IC
+to different thermal zones. This is achieved by means of using the
+#thermal-sensor-cells property and using the first cell of the sensor
+specifier as sensor ID. In the example, then, <bandgap 0> is used to
+monitor CPU thermal zone, <bandgap 1> is used to monitor GPU thermal
+zone and <bandgap 2> is used to monitor DSP thermal zone. Each zone
+may be uncorrelated, having its own dT/dt requirements, trips
+and cooling maps.
+
+
+(c) - Several sensors within one single thermal zone
+
+The example below illustrates how to use more than one sensor within
+one thermal zone.
+
+#include <dt-bindings/thermal/thermal.h>
+
+&i2c1 {
+ ...
+ /*
+ * A simple IC with a single temperature sensor.
+ */
+ adc: sensor@0x49 {
+ ...
+ #thermal-sensor-cells = <0>;
+ };
+};
+
+ocp {
+ ...
+ /*
+ * A simple IC with a single bandgap temperature sensor.
+ */
+ bandgap0: bandgap@0x0000ED00 {
+ ...
+ #thermal-sensor-cells = <0>;
+ };
+};
+
+thermal-zones {
+ cpu-thermal: cpu-thermal {
+ polling-delay-passive = <250>; /* milliseconds */
+ polling-delay = <1000>; /* milliseconds */
+
+ thermal-sensors = <&bandgap0>, /* cpu */
+ <&adc>; /* pcb north */
+
+ /* hotspot = 100 * bandgap - 120 * adc + 484 */
+ coefficients = <100 -120 484>;
+
+ trips {
+ ...
+ };
+
+ cooling-maps {
+ ...
+ };
+ };
+};
+
+In some cases, there is a need to use more than one sensor to extrapolate
+a thermal hotspot in the silicon. The above example illustrates this situation.
+For instance, it may be the case that a sensor external to CPU IP may be placed
+close to CPU hotspot and together with internal CPU sensor, it is used
+to determine the hotspot. Assuming this is the case for the above example,
+the hypothetical extrapolation rule would be:
+ hotspot = 100 * bandgap - 120 * adc + 484
+
+In other context, the same idea can be used to add fixed offset. For instance,
+consider the hotspot extrapolation rule below:
+ hotspot = 1 * adc + 6000
+
+In the above equation, the hotspot is always 6C higher than what is read
+from the ADC sensor. The binding would be then:
+ thermal-sensors = <&adc>;
+
+ /* hotspot = 1 * adc + 6000 */
+ coefficients = <1 6000>;
+
+(d) - Board thermal
+
+The board thermal example below illustrates how to setup one thermal zone
+with many sensors and many cooling devices.
+
+#include <dt-bindings/thermal/thermal.h>
+
+&i2c1 {
+ ...
+ /*
+ * An IC with several temperature sensor.
+ */
+ adc-dummy: sensor@0x50 {
+ ...
+ #thermal-sensor-cells = <1>; /* sensor internal ID */
+ };
+};
+
+thermal-zones {
+ batt-thermal {
+ polling-delay-passive = <500>; /* milliseconds */
+ polling-delay = <2500>; /* milliseconds */
+
+ /* sensor ID */
+ thermal-sensors = <&adc-dummy 4>;
+
+ trips {
+ ...
+ };
+
+ cooling-maps {
+ ...
+ };
+ };
+
+ board-thermal: board-thermal {
+ polling-delay-passive = <1000>; /* milliseconds */
+ polling-delay = <2500>; /* milliseconds */
+
+ /* sensor ID */
+ thermal-sensors = <&adc-dummy 0>, /* pcb top edge */
+ <&adc-dummy 1>, /* lcd */
+ <&adc-dymmy 2>; /* back cover */
+ /*
+ * An array of coefficients describing the sensor
+ * linear relation. E.g.:
+ * z = c1*x1 + c2*x2 + c3*x3
+ */
+ coefficients = <1200 -345 890>;
+
+ trips {
+ /* Trips are based on resulting linear equation */
+ cpu-trip: cpu-trip {
+ temperature = <60000>; /* millicelsius */
+ hysteresis = <2000>; /* millicelsius */
+ type = "passive";
+ };
+ gpu-trip: gpu-trip {
+ temperature = <55000>; /* millicelsius */
+ hysteresis = <2000>; /* millicelsius */
+ type = "passive";
+ }
+ lcd-trip: lcp-trip {
+ temperature = <53000>; /* millicelsius */
+ hysteresis = <2000>; /* millicelsius */
+ type = "passive";
+ };
+ crit-trip: crit-trip {
+ temperature = <68000>; /* millicelsius */
+ hysteresis = <2000>; /* millicelsius */
+ type = "critical";
+ };
+ };
+
+ cooling-maps {
+ map0 {
+ trip = <&cpu-trip>;
+ cooling-device = <&cpu0 0 2>;
+ contribution = <55>;
+ };
+ map1 {
+ trip = <&gpu-trip>;
+ cooling-device = <&gpu0 0 2>;
+ contribution = <20>;
+ };
+ map2 {
+ trip = <&lcd-trip>;
+ cooling-device = <&lcd0 5 10>;
+ contribution = <15>;
+ };
+ };
+ };
+};
+
+The above example is a mix of previous examples, a sensor IP with several internal
+sensors used to monitor different zones, one of them is composed by several sensors and
+with different cooling devices.
