* Richtek RT8973A - Micro USB Switch device



The Richtek RT8973A is Micro USB Switch with OVP and I2C interface. The RT8973A

is a USB port accessory detector and switch that is optimized to protect low

voltage system from abnormal high input voltage (up to 28V) and supports high

speed USB operation. Also, RT8973A support 'auto-configuration' mode.

If auto-configuration mode is enabled, RT8973A would control internal h/w patch

for USB D-/D+ switching.



Required properties:

- compatible: Should be "richtek,rt8973a-muic"

- reg: Specifies the I2C slave address of the MUIC block. It should be 0x14

- interrupts: Interrupt specifiers for detection interrupt sources.



Example:



	rt8973a@14 {

		compatible = "richtek,rt8973a-muic";

		interrupt-parent = <&gpx1>;

		interrupts = <5 0>;

		reg = <0x14>;

	};
