[PATCH 0/6] arm64: dts: renesas: Add support for R-Car H3Ne-1.7G

[Geert Uytterhoeven]

	Hi all,

This patch series adds support for the R-Car H3Ne-1.7G SoC (R8A779MB),
which is a different grading of the R-Car H3-N (R8A77951) SoC.  Board
support includes the Salvator-XS and H3ULCB development boards, and the
H3ULCB+Kingfisher board combo.  Note that unlike R-Car H3Ne (R8A779M8),
R-Car H3Ne-1.7G does support running the Cortex-A57 CPU cores at 1.7
GHz[1].

The last 3 patches are marked RFC, as I do not know which boards
will actually be produced with this SoC.

This has been prototyped and tested on Salvator-XS with R-Car H3 ES2.0.

I plan to queue (most) of this in renesas-devel for v5.21.

Thanks for your comments!

[PATCH 1/6] dt-bindings: arm: renesas: Document R-Car H3Ne-1.7G SoC and boards

[Geert Uytterhoeven]

Document the compatible values for the R-Car H3Ne-1.7G (R8A779MB)
SoC.  This is a different grading of the R-Car H3-N (R8A77951) SoC.

All R-Car H3Ne-1.7G on-SoC devices are identical to the corresponding
devices on the R-Car H3-N SoC, and thus just use the compatible values
for the latter.  The root compatible property does gain an additional
value, to sort out integration issues if they ever arise.

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

I'm sorry I should have informed you about this topic before.

So, please drop these supports.
