	Hi Rafael, Simon, Magnus,

This patch series enables DT support for PM domains on Renesas R-Mobile SoCs.

Currently it's limited to R-Mobile A1 (r8a7740), but given the similarity of
the SYSC System-Controller on the various SH-Mobile/R-Mobile SoCs, and the
abstraction of PM domains in DT, it should be sufficiently generic to handle
other SoCs in the future (e.g. SH-Mobile AP4 (sh7372), SH-Mobile AG5 (sh73a0),
R-Mobile APE6 (r8a73a4)).

Changes compared to v2 (more detailed changelogs in the individual patches):
  - Minor changes to attach/detach callbacks,
  - Really add the A4MP and D4 PM domains, as fixes are available (see
    dependencies below),
  - Scan DT topology to identify special PM domains (CPUs and console),
  - Move PM domain power-on/off latencies to a separate patch.

Changes compared to v1 (more detailed changelogs in the individual patches):
  - Several new patches: PM QoS device latencies in DT, attach/detach
    callbacks,
  - Run-Time management of the module clocks, making the hack in
    drivers/sh/pm_runtime.c obsolete for DT platforms using genpd,
  - Addition of PM QoS device latencies, specified from DT,
  - Addition of build glue, so this builds and runs without additional
    changes, incl. s2ram.

This means that functionality-wise, the DT version is now on par with the
legacy version ("[PATCH v2 00/11] ARM: shmobile: r8a7740/armadillo800eva legacy
PM domain support").

Dependencies:
  - Simon Horman's renesas-devel-20140924-v3.17-rc6,
  - Rafael J. Wysocki's linux-pm.git#linux-next,
  - Jason Cooper's linux.git#irqchip/for-next.
  - "ARM: shmobile: R-Mobile: Store SYSC base address in rmobile_pm_domain"
    depends on the legacy version of this series, but if the legacy version
    will never be accepted, the conflicts are trivial to resolve (drop changes
    to non-existing PM domains),
  - Working resume from s2ram depends on:
      - "[PATCH/RFC] fbdev: sh_mobile_hdmi: Re-init regs before irq re-enable
	on resume",
      - "[PATCH] ARM: hw_breakpoint: Trap undef instruction exceptions on
	wake-up", or an alternative solution.
  - Working "no_console_suspend" handling depends on "[PATCH 06/13] ARM:
    shmobile: armadillo800eva dts: Add chosen/stdout-path".

For your convenience, I've also pushed this (incl. its dependencies) to
git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git#rmobile-genpd

Rafael: If you accept "PM / Domains: Add genpd attach/detach callbacks", it
would be good to get this patch in v3.18-rc1, as it's the only hard dependency
on linux-pm.git for the rest of this series. The other parts have relaxed
ordering constraints due to the separation of code and DTS.

OK, this one looks good to me, so I can push it for 3.18.
