I've reviewed this by comparing this patch to the Linux stable 6.9.3
codebase located in drivers/usb/renesas_usbhs/ and the
phy driver (drivers/usb/renesas_usbhs/)

While I notice some differences, such as:
* no USB host support (no VBUS control support)
* no dma mapping control support
* no support for the older RCar controllers (rcar2)

This looks good overall.
