STUSB160x driver requires to get power operation mode via device tree, that's why this series also adds the optional DT property power-opmode for usb-c-connector to select the power operation mode capability and a function to convert the power operation mode string into power operation mode value. This driver has been tested on stm32mp157c-dk2 [2], which has a Type-C connector managed by STUSB1600, and connected to USB OTG controller.
