v2 cover arm64: renesas: Add support for R Car H3e 2G-and M3e-2G

Hi all,

The new R-Car Gen3e SoCs are different gradings of the existing R-Car Gen3 SoCs. This series adds support for the first two members of the
family: R-Car H3e-2G (R8A779M1) and R-Car M3e-2G (R8A779M3), on the Salvator-XS and ULCB (with and without Kingfisher) development boards.

Changes compared to v1[1]:
- Add Reviewed-by, Acked-by.
- Drop new fam_rcar_gen3e and soc_rcar_[hm]3e, just use the existing

    soc_rcar_{h3,m3_w},

- Drop pinctrl fix, which has evolved independently[2],
- Drop mmc fix, which has been superseded by a recent refactoring[3],
- Drop 2 GHz turbo modes, as the official opp-microvolt values are not yet available,
- Widen the audience.

This series has been tested on Salvator-X with R-Car H3 ES3.0 and Salvator-XS with R-Car M3-W+. For testing, a branch with dependencies and fixups to prototype R-Car Gen3e development on older Gen3 SoCs can be found at[4].

I plan to queue this in renesas-devel for v5.15.

Thanks for your comments!

PATCH v2 1/10 dt-bindings: arm: renesas: Document R-Car H3e-2G and M3e-2G SoCs and boards

Document the compatible values for the R-Car H3e-2G (R8A779M1) and M3e-2G (R8A779M3) SoCs. These are different gradings of the R-Car H3 ES3.0 (R8A77951) and M3-W+ (R8A77961) SoCs.

All R-Car Gen3e on-SoC devices are identical to the devices on the corresponding R-Car Gen3 SoCs, and thus just use the compatible values for the latter. The root compatible properties do gain an additional value, to sort out integration issues if they ever arise.

Document the use of these SoCs on the Salvator-XS and ULCB (with and without Kingfisher) development boards.

PATCH v2 2/10 soc: renesas: Identify R-Car H3e-2G and M3e-2G

In reply to Geert Uytterhoeven

Add support for identifying the R-Car H3e-2G (R8A779M1) and R-Car M3e-2G (R8A779M3) SoCs.

As these are different gradings of the already supported R-Car H3 ES3.0 (R8A77951) and M3-W+ (R8A77961) SoCs, support for them is enabled through the existing ARCH_R8A77951 and ARCH_R8A77961 configuration symbols.
