[PATCH 0/4] clk: renesas: cpg-mssr: Add support for R-Car M3-W

[Geert Uytterhoeven <geert+renesas@glider.be>]

	Hi Mike, Stephen,

This patch series adds initial support for the Clock Pulse Generator and
Module Standby and Software Reset modules on the Renesas R-Car M3-W
SoC:
  - Basic core clocks,
  - SCIF2 (console) module clock,
  - INTC-AP (GIC) module clock (disabled pending CLK_ENABLE_HAND_OFF).

Support for more core and module clocks will be added incrementally.

For your convenience, I've pushed this series to the
topic/r8a7796-clk-v1 branch of
https://git.kernel.org/cgit/linux/kernel/git/geert/renesas-drivers.git.

Integration with renesas-drivers-2016-04-26-v4.6-rc5, and minimal board
integration for testing is available in the topic/gen3-latest branch.

This has received minimal testing on r8a7796/salvator-x, and regression
testing on r8a7795/salvator-x (ES1.0 and ES1.1).

Thanks for your comments!
