1 * TWL4030's Keypad Controller device tree bindings
2
3 TWL4030's Keypad controller is used to interface a SoC with a matrix-type
4 keypad device. The keypad controller supports multiple row and column lines.
5 A key can be placed at each intersection of a unique row and a unique column.
6 The keypad controller can sense a key-press and key-release and report the
7 event using a interrupt to the cpu.
8
9 This binding is based on the matrix-keymap binding with the following
10 changes:
11
12 * keypad,num-rows and keypad,num-columns are required.
13
14 Required SoC Specific Properties:
15 - compatible: should be one of the following
16 - "ti,twl4030-keypad": For controllers compatible with twl4030 keypad
17 controller.
18 - interrupt: should be one of the following
19 - <1>: For controllers compatible with twl4030 keypad controller.
20
21 Example:
22 twl_keypad: keypad {
23 compatible = "ti,twl4030-keypad";
24 interrupts = <1>;
25 keypad,num-rows = <8>;
26 keypad,num-columns = <8>;
