| * 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>; | |
| }; |
