+Samsung tm2-touchkey
+
+Required properties:
+- compatible: must be "samsung,tm2-touchkey"
+- reg: I2C address of the chip.
+- interrupt-parent: a phandle for the interrupt controller (see interrupt
+ binding[0]).
+- interrupts: interrupt to which the chip is connected (see interrupt
+ binding[0]).
+- vcc-supply : internal regulator output. 1.8V
+- vdd-supply : power supply for IC 3.3V
+
+[0]: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+
+Example:
+ &i2c0 {
+ /* ... */
+
+ touchkey@20 {
+ compatible = "samsung,tm2-touchkey";
+ reg = <0x20>;
+ interrupt-parent = <&gpa3>;
+ interrupts = <2 IRQ_TYPE_EDGE_FALLING>;
+ vcc-supply=<&ldo32_reg>;
+ vdd-supply=<&ldo33_reg>;
+ };
