usb: chipidea: Configure phy for appropriate mode (490b63e6) · Commits · 戴 / test

When the qcom chipidea controller is used with an extcon, we need to signal device mode or host mode to the phy so it can configure itself for the correct mode. This should be done after the phy is powered up, so that the register writes work correctly. Add in the appropriate phy_set_mode() call here.
