The Renesas R-Car System Controller provides power management for the
CPU cores and various coprocessors, following the generic PM domain
bindings in Documentation/devicetree/bindings/power/power_domain.txt.
This supports R-Car Gen1 (H1), Gen2, and Gen3.

+DT bindings for the Renesas R-Car System Controller
+
+== System Controller Node ==
+
+The R-Car System Controller provides power management for the CPU cores and
+various coprocessors.
+
+Required properties:
+ - compatible: Must contain exactly one of the following:
+ - "renesas,r8a7779-sysc" (R-Car H1)
+ - "renesas,r8a7790-sysc" (R-Car H2)
+ - "renesas,r8a7791-sysc" (R-Car M2-W)
+ - "renesas,r8a7792-sysc" (R-Car V2H)
+ - "renesas,r8a7793-sysc" (R-Car M2-N)
+ - "renesas,r8a7794-sysc" (R-Car E2)
+ - "renesas,r8a7795-sysc" (R-Car H3)
+ - reg: Address start and address range for the device.
+ - #power-domain-cells: Must be 1.
+
+
+Example:
+
+ sysc: system-controller at e6180000 {
+ compatible = "renesas,r8a7791-sysc";
+ reg = <0 0xe6180000 0 0x0200>;
+ #power-domain-cells = <1>;
+ };
+
+
+== PM Domain Consumers ==
+
+Devices residing in a power area must refer to that power area, as documented
+by the generic PM domain bindings in
+Documentation/devicetree/bindings/power/power_domain.txt.
+
+Required properties:
+ - power-domains: A phandle and symbolic PM domain specifier, as defined in
+ <dt-bindings/power/r8a77*-sysc.h>.
+
+
+Example:
+
+ L2_CA15: cache-controller at 0 {
+ compatible = "cache";
+ power-domains = <&sysc R8A7791_PD_CA15_SCU>;
+ cache-unified;
+ cache-level = <2>;
+ };

R-Car M2-N is identical to R-Car M2-W w.r.t. power domains, so reuse the
definitions from the latter.

This seems to best fit into next/dt, but we can also stick it into other
branches if it's needed as a dependency.
Pulled now, thanks!

Hi Arnd,
Unfortunately this is more complex than I expected when I prepared this
pull request though the pull request itself is still correct.
There are driver changes that seem to logically fit on top of this pull
request. Though strictly speaking I don't believe there are any hard
run-time dependencies.
Then there are DT changes to enable the new driver that have
hard run-time dependencies on the driver changes themselves.
I have queued things up as described above and you can see them in the
renesas-next-20160422v3-v4.6-rc1 tag of next branch of the renesas tree.
I am planning to send corresponding pull requests in the near future.
I would be very happy to hear any feedback you have before I take that
step.
