* 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.
|
|
|
|
Example:
|
|
twl_keypad: keypad {
|
|
compatible = "ti,twl4030-keypad";
|
|
interrupts = <1>;
|
|
keypad,num-rows = <8>;
|
|
keypad,num-columns = <8>;
|
|
};
