The RT8973A 5*4882a593Smuzhiyunis a USB port accessory detector and switch that is optimized to protect low 6*4882a593Smuzhiyunvoltage system from abnormal high input voltage (up to 28V) and supports high 7*4882a593Smuzhiyunspeed USB operation. Also, RT8973A support 'auto-configuration' mode. 8*4882a593SmuzhiyunIf auto-configuration mode is enabled, RT8973A would control internal h/w patch 9*4882a593Smuzhiyunfor USB D-/D+ switching. 10*4882a593Smuzhiyun 11*4882a593SmuzhiyunRequired properties: 12*4882a593Smuzhiyun- compatible: Should be "richtek,rt8973a-muic" 13*4882a593Smuzhiyun- reg: Specifies the I2C slave address of the MUIC block.
