Subject: [PATCH 0/4] Add CANFD support to R9A09G056/057/077/087 SoCs

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

Hi All,

This patch series adds CANFD support to RZ/V2H(P), RZ/V2N, RZ/T2H and
RZ/N2H SoCs.
The CANFD controller on RZ/V2H(P) and RZ/V2N SoCs is similar to the one
on RZ/G3E SoC, while the CANFD controller on RZ/T2H and RZ/N2H SoCs is
similar to R-Car Gen 4 SoCs but with some differences in terms of
number of channels and AFLPN and CFTML bits.

The patch series includes:
- Specifying reset-names for RZ/G2L and RZ/G3E CANFD controllers.
- Documenting the CANFD controller on RZ/V2H(P) and RZ/V2N SoCs.
- Documenting the CANFD controller on RZ/T2H and RZ/N2H SoCs.
- Adding RZ/T2H SoC support in the rcar_canfd driver.c file.

Cheers,
Prabhakar
