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. This is a prerequisite for
enabling devices (e.g. VSP and FCP) that reside in power areas.
/sys/kernel/debug/pm_genpd/pm_genpd_summary output:

always-on on ca57-scu, ca53-scu, cr7, a3vc, 3dg-a, a3ir
/devices/platform/soc/e6e88000.serial active
Changes compared to v1:
- Add Acked-by.
For your convenience, I've pushed this series to the
topic/r8a7796-sysc-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.
Thanks!
