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.

Note this patch series applies on top of:
https://lore.kernel.org/all/20251126155911.320563-1-biju.das.jz@xxxxxxxxxxxxxx/

v2->v3:
- Updated commit message to clarify that reset-names existed previously
but was dropped for patch 1/4.
- Grouped single compatible entries into an enum in patch 3/4.
- Updated commit message about disallowing reset-names property
for patch 3/4.
- Added Acked-by and Reviewed-by tags.

v1->v2:
- Moved reset-names to top-level properties.

Cheers,
Prabhakar
