+Raydium I2C touchscreen
+
+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:
+ touchscreen@39 {
+ compatible = "raydium,rm32380";
+ reg = <0x39>;
+ interrupt-parent = <&gpio>;
+ interrupts = <0x0 IRQ_TYPE_EDGE_FALLING>;
+ };
