[PATCH v2 0/3] ARM: shmobile: r8a73a4: DT PM domain support

[Geert Uytterhoeven]

	Hi Simon, Magnus,

This patch series enables DT support for PM domains on the Renesas
R-Mobile APE6 (r8a73a4) SoC.  As a bonus, it also allows the use of the
R-Mobile Reset driver to restart the system.

This series builds further upon the DT PM Domain support for R-Mobile
A1 (r8a7740) and SH-Mobile AG5 (sh73a0).  Due to the similarity of the
SYSC System-Controller on the various SH-Mobile/R-Mobile SoCs, and the
abstraction of PM domains in DT, the same driver can handle r8a73a4,
without any additional modifications, and without changing the DT
bindings.

Dependencies:
  - Patch 1 (DT binding doc) depends on Simon's tag renesas-dt2-for-v3.20,
    which should be upstream tonight,
  - Patch 2 (dtsi) depends on the series "[PATCH v4 0/6] ARM: shmobile:
    r8a73a4/ape6evm: Complete multiplatform support",
  - Patch 3 (drivers/sh) depends functionally on patch 2, and literally on
    the series "[PATCH v3 0/2] ARM: shmobile: sh73a0: Enable DT PM domain
    support".

Thanks for applying!
