+ChromeOS EC Keyboard
+
+Google's ChromeOS EC Keyboard is a simple matrix keyboard implemented on
+a separate EC (Embedded Controller) device. It provides a message for reading
+key scans from the EC. These are then converted into keycodes for processing
+by the kernel.
+
+This binding is based on matrix-keymap.txt and extends/modifies it as follows:
+
+Required properties:
+- compatible: "google,cros-ec-keyb"
+
+Optional properties:
+- google,needs-ghost-filter: True to enable a ghost filter for the matrix
+keyboard. This is recommended if the EC does not have its own logic or
+hardware for this.
+
+
+Example:
+
+cros-ec-keyb {
+ compatible = "google,cros-ec-keyb";
+ keypad,num-rows = <8>;
+ keypad,num-columns = <13>;
+ google,needs-ghost-filter;
+ /*
+ * Keymap entries take the form of 0xRRCCKKKK where
+ * RR=Row CC=Column KKKK=Key Code
+ * The values below are for a US keyboard layout and
+ * are taken from the Linux driver. Note that the
+ * 102ND key is not used for US keyboards.

+* Marvell PXA Keypad controller
+
+Required Properties
+- compatible : should be "marvell,pxa27x-keypad"
+- reg : Address and length of the register set for the device
+- interrupts : The interrupt for the keypad controller
+- marvell,debounce-interval : How long time the key will be
+ recognized when it is pressed. It is a u32 value, and bit[31:16]
+ is debounce interval for direct key and bit[15:0] is debounce
+ interval for matrix key. The value is in binary number of 2ms
+
+Optional Properties For Matrix Keyes
+Please refer to matrix-keymap.txt
+
+Optional Properties for Direct Keyes
+- marvell,direct-key-count : How many direct keyes are used.
+- marvell,direct-key-mask : The mask indicates which keyes
+ are used. If bit[X] of the mask is set, the direct key X
+ is used.
+- marvell,direct-key-low-active : Direct key status register
+ tells the level of pins that connects to the direct keyes.
+ When this property is set, it means that when the pin level
+ is low, the key is pressed(active).
+- marvell,direct-key-map : It is a u16 array. Each item indicates
+ the linux key-code for the direct key.
+
+Optional Properties For Rotary
+- marvell,rotary0 : It is a u32 value. Bit[31:16] is the
+ linux key-code for rotary up. Bit[15:0] is the linux key-code
+ for rotary down. It is for rotary 0.
+- marvell,rotary1 : Same as marvell,rotary0. It is for rotary 1.
+- marvell,rotary-rel-key : When rotary is used for relative axes
+ in the device, the value indicates the key-code for relative
+ axes measurement in the device. It is a u32 value. Bit[31:16]
+ is for rotary 1, and Bit[15:0] is for rotary 0.

+
+- reg: Physical base address of the peripheral and length of memory mapped
+ region.
+
+- interrupts: The interrupt number for the peripheral.
+
+- scan-interval: How often to scan in us. Based on a APB speed of 33MHz, the
+ maximum and minimum delay time is ~2000us and ~500us respectively
+
+- row-delay: How long to wait before scanning each row.
+
+- clocks: The clock this peripheral is attached to.
+
+- linux,keymap: The keymap to use
+ (see Documentation/devicetree/bindings/input/matrix-keymap.txt)
+
+Optional properties:
+- active-low: Specify that the keypad is active low (i.e. logical low signifies
+ a key press).
+
+Example:
+
