+Required properties:
+- compatible : must be "raydium,rm32380"
+- reg: The I2C address of the device
+- interrupt-parent: the phandle for the interrupt controller
+- interrupts: interrupt to which the chip is connected
+    See ../interrupt-controller/interrupts.txt
+Optional properties:
+- avdd-supply : analog power supply needed to power device
+- vccio-supply : IO Power source
+- reset-gpios : reset gpio the chip is connected to.
+
+Example:
+	raydium_i2c@39 {
+		compatible = "raydium,rm32380";
+		reg = <0x39>;
+		interrupt-parent = <&gpio>;
+		interrupts = <0x0 IRQ_TYPE_EDGE_FALLING>;
