[PATCH v4 0/5] Add the Renesas USBF controller support

[Herve Codina <herve.codina@bootlin.com>]

Hi,

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

Based on previous iteration:
  https://lore.kernel.org/all/20221207162435.1001782-1-herve.codina@bootlin.com/
The 'depends-on' property was removed.

Patches 1, 3, 4 and 5 are related to the USBF controller with a new
binding definition, the driver itself and myself as a maintainer
of this controller.

Patch 2 handles h2mode in sysctrl.

Hope that this v4 can lead to some feedbacks on the USB device
controller itself (patch 3).

Best regards,
Herve Codina
