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>; + }; |
