+Device tree bindings for i.MX Wireless External Interface Module (WEIM)
+
+The term "wireless" does not imply that the WEIM is literally an interface
+without wires. It simply means that this module was originally designed for
+wireless and mobile applications that use low-power technology.
+
+The actual devices are instantiated from the child nodes of a WEIM node.
+
+Required properties:
+
+ - compatible: Should be set to "fsl,imx6q-weim"
+ - reg: A resource specifier for the register space
+ (see the example below)
+ - clocks: the clock, see the example below.
+ - #address-cells: Must be set to 2 to allow memory address translation
+ - #size-cells: Must be set to 1 to allow CS address passing
+ - ranges: Must be set up to reflect the memory layout with four
+ integer values for each chip-select line in use:
+
+ <cs-number> 0 <physical address of mapping> <size>
+
+Timing property for child nodes. It is mandatory, not optional.
+
+ - fsl,weim-cs-timing: The timing array, contains 6 timing values for the
+ child node. We can get the CS index from the child
+ node's "reg" property. This property contains the values
+ for the registers EIM_CSnGCR1, EIM_CSnGCR2, EIM_CSnRCR1,
+ EIM_CSnRCR2, EIM_CSnWCR1, EIM_CSnWCR2 in this order.
+
+Example for an imx6q-sabreauto board, the NOR flash connected to the WEIM:
+
+ weim: weim@021b8000 {
+ compatible = "fsl,imx6q-weim";
+ reg = <0x021b8000 0x4000>;
+ clocks = <&clks 196>;
+ #address-cells = <2>;
+ #size-cells = <1>;
+ ranges = <0 0 0x08000000 0x08000000>;
+
+ nor@0,0 {
+ compatible = "cfi-flash";
+ reg = <0 0 0x02000000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ bank-width = <2>;
+ fsl,weim-cs-timing = <0x00620081 0x00000001 0x1c022000
+ 0x0000c000 0x1404a38e 0x00000000>;
+ };
+ };
