* TWL4030's Keypad Controller device tree bindings
TWL4030's Keypad controller is used to interface a SoC with a matrix-type
keypad device. The keypad controller supports multiple row and column lines.
A key can be placed at each intersection of a unique row and a unique column.
The keypad controller can sense a key-press and key-release and report the
event using a interrupt to the cpu.
This binding is based on the matrix-keymap binding with the following
changes:
* keypad,num-rows and keypad,num-columns are required.
Required SoC Specific Properties:
- compatible: should be one of the following
- "ti,twl4030-keypad": For controllers compatible with twl4030 keypad
controller.
- interrupt: should be one of the following
- <1>: For controllers compatible with twl4030 keypad controller.
Optional Properties specific to linux:
- linux,keypad-no-autorepeat: do no enable autorepeat feature.
Example:
twl_keypad: keypad {
compatible = "ti,twl4030-keypad";
interrupts = <1>;
keypad,num-rows = <8>;
keypad,num-columns = <8>;
linux,keypad-no-autorepeat;
};
