3Required properties:
4- compatible: must be "cypress,tm2-touchkey"
5- reg: I2C address of the chip.
6- interrupt-parent: a phandle for the interrupt controller (see interrupt
7 binding[0]).
8- interrupts: interrupt to which the chip is connected (see interrupt
9 binding[0]).
10- vcc-supply : internal regulator output. 1.8V
