* 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>;
|
|
};
