Both USB Host (pci0) and Function (USBHS) drivers are enabled.
The USB PHY driver determines which IP block should be connected
based on vbus and id signals read via gpios.
Note that switch SW5 and SW6 on Koelsch board needs to be set to
position 3 for this to work.
---
Not for upstream until the following patches have been accepted:
"usb: renesas_usbhs: Allow an OTG PHY driver to provide VBUS"
"phy: rcar-gen2 usb: Add Host/Function switching for USB0"
Hence, not signed off.
v2:
- Added -gpio to dts prop names of GPIO pins.
