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>; }; |
