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.

Changes compared to v1:
- Add Acked-by, Tested-by.
For your convenience, I've pushed this series to the
topic/r8a7796-clk-v2 branch of
https://git.kernel.org/cgit/linux/kernel/git/geert/renesas-drivers.git.
This has been tested on r8a7796/salvator-x, and the code (minus the
acks, i.e. v1), has been part of renesas-drivers since 2016-05-10.
I plan to queue this in my clk-renesas-for-v4.8 branch, and send a pull
request later.
Thanks!
