-* 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>;
-       };
