[PATCH 0/2] arm64: renesas: Add support for R-Car V3M

[PATCH 0/2] arm64: renesas: Add support for R-Car V3M

[Geert Uytterhoeven]

	Hi all,

This patch series adds initial R-Car V3M infrastructure:
  1. SoC DT bindings,
  2. Main Kconfig symbol.

Both follow the example set by R-Car D3 aka r8a77995, using 5-digit instead
of 4-digit part numbers.
Alternatively, we could stick to 4-digit part numbers if the fifth digit is
a zero.

For your convenience, a branch with more preliminary work (thanks Sergei,
for posting the clock driver!) for testing on v3m/eagle is also available
in the topic/r8a77970-integration branch of my renesas-drivers git
repository at
git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git.

Thanks for your comments!

This looks good to me.

I am in favour of using the 5-digit scheme for all new R-Car Gen 3 SoCs
as it seems the safest option with regards to as yet unknown (to me) part
numbers..

Geert, any objections to me applying these?
I'm happy to wait longer if you prefer.

It would be good to have an ack from Rob.
No need to hurry.

Rob has acked the DT binding patch and I have applied the series.
