[00/15] arm64: renesas: Add R-Car V4M and Gray Hawk Single support

Hi all,

This patch series adds initial support for the Renesas R-Car V4M
(R8A779G0) SoC and the Renesas Gray Hawk Single development board.

As both driver code and DTS have hard dependencies on DT binding
definitions, all patches in this series are supposed to go in through
the renesas-devel, renesas-clk, and/or renesas-pmdomain trees, using a
shared branch for DT binding definitions, as usual.

Note that this series does not include the DT binding update for the
HSCIF serial ports, as Greg does not like receiving new patches during
the merge window.

For testing, this series can be found at
https://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git/log/?h=topic/v4m-gray-hawk-single-v1

Thanks for your comments (especially about the naming of the compatible
value and DTB for Gray Hawk Single :-)!
