1 2* Richtek RT8973A - Micro USB Switch device 3 4The Richtek RT8973A is Micro USB Switch with OVP and I2C interface. The RT8973A 5is a USB port accessory detector and switch that is optimized to protect low 6voltage system from abnormal high input voltage (up to 28V) and supports high 7speed USB operation. Also, RT8973A support 'auto-configuration' mode. 8If auto-configuration mode is enabled, RT8973A would control internal h/w patch 9for USB D-/D+ switching. 10 11Required properties: 12- compatible: Should be "richtek,rt8973a-muic" 13- reg: Specifies the I2C slave address of the MUIC block. It should be 0x14 14- interrupt-parent: Specifies the phandle of the interrupt controller to which 15 the interrupts from rt8973a are delivered to. 16- interrupts: Interrupt specifiers for detection interrupt sources. 17 18Example: 19 20 rt8973a@14 { 21 compatible = "richtek,rt8973a-muic"; 22 interrupt-parent = <&gpx1>; 23 interrupts = <5 0>; 24 reg = <0x14>; 25 }; 26
