Instead of statically selecting the PHY connection to either the

These GPIOs don't have anything to do with the PHY, they're interfacing Maxim MAX3355 OTG chip for which I have submitted the extcon driver.

gpio pins are used to control power to an external OTG device and
an override to turn vbus on/off.

Note: the R-Car USB PHY only allows this Host/Function switching
on channel 0.

This has been tested on a r8a7791 based Koelsch board, which uses
a MAX3355 device to supply vbus power when needed.

   I'm inclined to NAK this. You're modifying the wrong driver, I think.
