[PATCH 00/18] Add USB2.0 support for RZ/G3E

[Tommaso Merciai]

Dear All,

This patch series adds USB2.0 support for the Renesas R9A09G047 (RZ/G3E)
SoC and enables it on the RZ/G3E SMARC II board.
The RZ/G3E USB2.0 IP is identical to that used in the RZ/V2H (R9A09G057),
so the existing support has been extended accordingly.

The series applies on top of [1] and [2] and includes driver cleanups,
VBUS/OTG handling fixes, regulator improvements, clock/reset additions,
and device tree updates for RZ/G3E, RZ/V2H, and RZ/V2N SoCs and boards.

Thanks & Regards,
Tommaso
