[PATCH 0/4] arm64: renesas: Add support for Gray Hawk Single with R-Car V4M-7

[Geert Uytterhoeven]

        Hi all,

This patch series adds support for the Gray Hawk Single development
board variant equipped with an R-Car V4M-7 SoC.

Changes compared to the internal RFC:
  - Correct board part number.

I plan to queue this in renesas-devel for v6.17.

Thanks for your comments!

[PATCH 1/4] dt-bindings: soc: renesas: Document R-Car V4M-7 Gray Hawk Single

[Geert Uytterhoeven]

Document the compatible values for the Renesas R-Car V4M-7
(R8A779H2) SoC, as used on the Renesas Gray Hawk Single board.
R-Car V4M-7 is an updated version of R-Car V4M (R8A779H0).

[PATCH 4/4] arm64: dts: renesas: r8a779h2: Add Gray Hawk Single support

[Geert Uytterhoeven]

The Gray Hawk Single board with R-Car V4M-7 (R8A779H2) uses an updated
version of the R-Car V4M (R8A779H0) SoC.

For now, there are no visible differences compared to the variant
equipped with an R-Car V4M (R8A779H0) SoC.
