| * TI's Keypad Controller device tree bindings |
| |
| TI'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. |
| |
| Required SoC Specific Properties: |
| - compatible: should be one of the following |
| - "ti,omap4-keypad": For controllers compatible with omap4 keypad |
| controller. |
| |
| Required Board Specific Properties, in addition to those specified by |
| the shared matrix-keyboard bindings: |
| - keypad,num-rows: Number of row lines connected to the keypad |
| controller. |
| |
| - keypad,num-columns: Number of column lines connected to the |
| keypad controller. |
| |
| Optional Properties specific to linux: |
| - linux,keypad-no-autorepeat: do no enable autorepeat feature. |
| |
| Example: |
| keypad@4ae1c000{ |
| compatible = "ti,omap4-keypad"; |
| keypad,num-rows = <2>; |
| keypad,num-columns = <8>; |
| linux,keypad-no-autorepeat; |
| }; |
