Hi Olof, Hi Kevin, Hi Arnd,
Please consider these Renesas ARM based SoC drivers updates for v4.15.
The following changes since commit 2bd6bf03f4c1c59381d62c61d03f6cc3fe71f66e:
Linux 4.14-rc1 (2017-09-16 15:47:51 -0700)
are available in the git repository at:
https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git tags/renesas-drivers-for-v4.15

soc: renesas: rcar-sysc: add R8A77970 support (2017-09-18 09:46:50 +0200)
----------------------------------------------------------------
Renesas ARM Based SoC Drivers Updates for v4.15
Add basic support for R-Car V3M (R8A77970) SoC.
Sergei Shtylyov says:
* Add support for R-Car V3M (R8A77970) SoC power areas to the R-Car SYSC
driver
* Add support for identifying the R-Car V3M (R8A77970) SoC
* Add support for R-Car V3M (R8A77970) to the R-Car RST driver -- this
driver is needed for the clock driver to work
