Hi,

This series add support for the Renesas USBF controller (USB Device
Controller) available in the Renesas RZ/N1 SoC.

The first three patches are related to the H2MODE bit from CFG_USB
register. This register is managed by the Renesas sysctrl driver.
The H2MODE bit allows to configure the internal USB Port interface
for two hosts or one host and one device.

The next patches are related to the USBF controller with a new
binding definition, the driver itself and myself as a maintainer
of this controller.

Best regards,
Herve Codina
