Merge tag 'renesas-drivers-for-v4.15' of... 

Merge tag 'renesas-drivers-for-v4.15' of https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/drivers

Pull "Renesas ARM Based SoC Drivers Updates for v4.15" from Simon Horman:

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

* tag 'renesas-drivers-for-v4.15' of https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
  soc: renesas: rcar-sysc: add R8A77970 support
  soc: renesas: identify R-Car V3M
  soc: renesas: rcar-rst: add R8A77970 support
