	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!
