- * 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
- - interrupt-parent: Specifies the phandle of the interrupt controller to which
- the interrupts from rt8973a are delivered to.
- - interrupts: Interrupt specifiers for detection interrupt sources.
- Example:
- rt8973a@14 {
- compatible = "richtek,rt8973a-muic";
- interrupt-parent = <&gpx1>;
- interrupts = <5 0>;
- reg = <0x14>;
- };
