Hi Simon, Magnus,
This patch series adds support for the power areas exposed by the System
Controller on the Renesas R-Car M3-W SoC.

For your convenience, I've pushed this series to the
topic/r8a7796-sysc-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.
Thanks for your comments!
