Perhaps I don't understand the pinctrl world yet, but I have a question.
In r8a7791, the USB0_PWEN is GP7_23 and the USB0_OVC is GP7_24. And,
the "usb0_pins" is related to these USB0 pins. But, as you know,
the koelsch has a OTG ID pin and it connects to GP5_31 via MAX3355 chip.
So, would you tell me why koelsch needs the pinctrl?

The GPIO pins are not requested via pinctrl.
So, would you tell me why koelsch needs the pinctrl?
Because at least USB0_OVC/VBUS is used by HS-USB. I decided not to modify
the R8A7791 PFC driver in order to create a group consisting of that signal
alone (like on R8A7790), because we don't need to read GP7_23 on these boards,
unlike Lager.

Thank you very much for the reply.
Finally I understood why it needs the princtrl.
(I didn't know the HS-USB will use the USB0_OVC/VBUS for detecting VBUS...)
