* 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. 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,omap4-keypad": For controllers compatible with omap4 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; };
