| * 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>; |
| }; |
