[PATCH 0/2] usb: gadget: Add Renesas RZ/N1 USBF driver

[Romain Gantois]

Hello everyone,

This series adds support for the Renesas USBF controller, which is used in
the RZ/N1 SoC. This will facilitate exposing USB gadgets from RZ/N1 SoCs in
U-Boot.

The driver was ported from the Linux kernel. The following features were
removed to reduce the memory footprint of the driver, and to avoid
including features not relevant to U-Boot:

 - Suspend/resume
 - Handling of endpoints > 2
 - Dynamic detection of endpoint DMA capability (DMA capability is
   predetermined for each endpoint anyway).

Best regards,

Romain
