  The USB OTG controller provides the USB data available on stm32mp135f-dk,
on the Type-C connector. Data role is determined by "usb-role-switch".

A STM32G0 provides the USB Type-C and Power Delivery connectivity.
It controls dual role power and dual role data through UCSI protocol over
I2C. It's wired on I2C1, with an interrupt pin on PI2 GPIO.
Its firmware maybe updated over I2C, so use the optional firmware-name
to enable firmware update.

Node names should be generic, usually typec.
