The DK1 and DK2 boards use the USB Type-C controller STUSB1600. This patch updates: - the device tree to add the I2C node in the DT - the board stm32mp1 to probe this I2C device and use this controller to check cable detection. - the DWC2 driver to support a new dt property "u-boot,force-b-session-valid" which forces B session and device mode; it is a workaround because the VBUS sensing and ID detection isn't available with stusb1600.
