Here's V3 of prototype support for the r8a77965 Salvator-X.
This version is based on "renesas-drivers-2018-02-13-v4.16-rc1".
By up-porting this patch I am able to track which part of M3-N support
that yet to be merged in mainline. If all goes well then new versions of
this patch will reduce in size over time.
The following patches are picked from renesas-bsp @ kernel.org and
in particular the recent "rcar-3.5.9.rc2" release:
dca5c4d1adc6 arm64: renesas: Add Renesas R8A77965 Kconfig support
6f3c0086b8b2 soc: renesas: identify R-Car M3N
711dec8fc1df soc: renesas: rcar-rst: Add R8A77965 support (*)
c8418d81dd26 clk: renesas: Add r8a77965 CPG Core Clock Definitions
d642ad7d1a40 clk: renesas: cpg-mssr: Add support for R-Car M3N (*)
4cec6dcde2f5 arm64: dts: r8a77965: Add Renesas R8A77965 SoC support (*)
92be4952a4d5 arm64: dts: r8a77965-salvator-x: Add Salvator-X board on R8A77965
SoC support (*)
1c69363cc1eb arm64: dts: r8a77965-salvator-x: Add reserved memory regions

Commits marked with (*) above have been updated to fit on upstream
Since this is prototype code and not suitable for mainline merge as-is:
