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.
