* Freescale MPR121 Controllor
Required Properties:
- compatible: Should be "fsl,mpr121-touchkey"
- reg: The I2C slave address of the device.
- interrupts: The interrupt number to the cpu.
- vdd-supply: Phandle to the Vdd power supply.
- linux,keycodes: Specifies an array of numeric keycode values to
be used for reporting button presses. The array can
contain up to 12 entries.
Optional Properties:
- wakeup-source: Use any event on keypad as wakeup event.
- autorepeat: Enable autorepeat feature.
Example:
#include "dt-bindings/input/input.h"
touchkey: mpr121@5a {
compatible = "fsl,mpr121-touchkey";
reg = <0x5a>;
interrupt-parent = <&gpio1>;
interrupts = <28 2>;
autorepeat;
vdd-supply = <&ldo4_reg>;
linux,keycodes = <KEY_0>, <KEY_1>, <KEY_2>, <KEY_3>,
<KEY_4> <KEY_5>, <KEY_6>, <KEY_7>,
<KEY_8>, <KEY_9>, <KEY_A>, <KEY_B>;
