Merge tag 'renesas-fixes4-for-v3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into fixes

From Simon Horman:
Fourth Round of Renesas ARM based SoC fixes for v3.12

* Remove unused #gpio-ranges-cells DT property

* Remove usage of deprecated #gpio-range-cells DT property
  from GPIO R-Car

  Property was deprecated in v3.11-rc2

* Correct ether pinctl naming for armadillo800eva board

  Regression introduced in v3.10-rc5

* Add Micrel KSZ8041 PHY fixup to lager board

  This resolves a problem that has been present since 3.11-rc2

* Update SDHI DT compatibility string to the <unit>-<soc> format

  This makes compatibility strings consistent across all renesas
  hardware which currently supports DT.

  The bindings which are being updated where intorodiced on
  a per-SoC basis starting in v3.8-rc7. They may have
  been internally consistent when originally added.

* tag 'renesas-fixes4-for-v3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
  ARM: shmobile: Remove #gpio-ranges-cells DT property
  gpio: rcar: Remove #gpio-range-cells DT property usage
  ARM: shmobile: armadillo: fixup ether pinctrl naming
  ARM: shmobile: Lager: add Micrel KSZ8041 PHY fixup
  ARM: shmobile: update SDHI DT compatibility string to the <unit>-<soc> format

-When used with Renesas SDHI hardware, the following compatibility strings
-configure various model-specific properties:
