-* mcs_touchkey MELFAS MCS5000/5080 controller

-Required properties:
-- compatible: must be "mcs5000_touchkey" or "mcs5080_touchkey"
-- reg : I2C address of the chip
-- interrupts: interrupt to which the chop is connected
-- key_maxval: size of keycode table
-- interrupts: interrupt to which the chip is connected
-- code: key code for this device

-Example:
-
-	i2c_touch_key: i2c-gpio-0 {
-	       /* ... */
-
-	       touch_key@20 {
-		       compatible = "mcs5080_touchkey";
