These patches enable support for USB 2.0 on the Renesas RZ/G2L EVK,
supporting both the USB Type-A port and the USB OTG port. It is possible
to load and boot Linux from a USB Mass Storage device connected to
either port.
There should be no change to the operation of R-Car gen3 boards, but I
don't have any of them available to test to confirm this myself.
Changes v1->v2:
- Add missing include <dm/device-internal.h> in
reset-rzg2l-usbphy-ctrl.c.
- Simplify reset control: we can just set the RESET_SEL_* bits in
rzg2l_usbphy_ctrl_probe() and leave them set.
- Use clrbits_le32() in rzg2l_usbphy_ctrl_deassert().
- Include return value of the failing function in dev_err() prints.
- Capitalise G in "R-Car Gen3".
- Added Marek's Reviewed-by tags.
