Subject: [PATCH 0/2] Add USBHS support for RZ/T2H and RZ/N2H SoCs

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Hi All,

This patch series adds support for the USBHS controller on the Renesas
RZ/T2H (r9a09g077) and RZ/N2H (r9a09g087) SoCs. The USBHS controller on
these SoCs is functionally similar to the one found on the RZ/G2L, but
there are some differences in terms of interrupt configuration,
clock/reset requirements, and register bit definitions.

The first patch updates the device tree bindings to include these SoCs,
while the second patch modifies the USBHS driver to recognize the new
compatible strings and use the existing platform information for the
RZ/G2L.

Cheers,
Prabhakar
