-* Freescale i.MX Keypad Port(KPP) device tree bindings
-
-The KPP is designed to interface with a keypad matrix with 2-point contact
-or 3-point contact keys. The KPP is designed to simplify the software task
-of scanning a keypad matrix. The KPP is capable of detecting, debouncing,
-and decoding one or multiple keys pressed simultaneously on a keypad.
-
-Required SoC Specific Properties:
-- compatible: Should be "fsl,<soc>-kpp".
-
-- reg: Physical base address of the KPP and length of memory mapped
- region.
-
-- interrupts: The KPP interrupt number to the CPU(s).
-
-- clocks: The clock provided by the SoC to the KPP. Some SoCs use dummy
-clock(The clock for the KPP is provided by the SoCs automatically).
-
-Required Board Specific Properties:
-- pinctrl-names: The definition can be found at
-pinctrl/pinctrl-bindings.txt.
-
-- pinctrl-0: The definition can be found at
-pinctrl/pinctrl-bindings.txt.
-
-- linux,keymap: The definition can be found at
-bindings/input/matrix-keymap.txt.
-
-Example:
-kpp: kpp@73f94000 {
- compatible = "fsl,imx51-kpp", "fsl,imx21-kpp";
- reg = <0x73f94000 0x4000>;
- interrupts = <60>;
- clocks = <&clks 0>;
- pinctrl-names = "default";
- pinctrl-0 = <&pinctrl_kpp_1>;
