        Hi Linus, Alex, Laurent, Simon, Magnus,

This patch series moves the setup of the GPIO-PFC pin mapping for
Renesas PFC/GPIO combos from C code to DT, and does some cleanups.
The move to DT is needed to make the GPIO hogging mechanism work, cfr.
the discussion following "[PATCH] [RFC] gpio: Retry deferred GPIO
hogging on pin range change" (https://lkml.org/lkml/2015/6/16/455).

The series consists of 3 parts:
  a. Patches 1-3 add the missing "gpio-ranges" properties to the dtsi
     files for all affected SoCs,
  b. Patch 4 disables the C code to set up the mapping on DT platforms
     (it's still needed on SH or ARM-legacy),
  c. Patches 5-7 do a few more cleanups in the sh-pfc gpio code.

Dependencies:
  - This series applies against next-next-20150630.
  - Part a must go in first, to avoid regressions.
    In addition, it's a prerequisite for "ARM: shmobile: armadillo800eva
    dts: Add pinctrl and gpio-hog for lcdc0", which has been queued up
    already in Simon's dt-for-v4.3 branch. Perhaps it can still be
    reordered?
  - While I didn't notice any bad behavior by having part a only, part b
    should go in immediately after part a. Hence I think it's best if
    Simon can take this one, too.
  - Part c is independent (it doesn't touch the same code), so it can go
    in before or after the other parts, or in parallel.

Thanks for applying!

I'm happy of shmobile people are happy.
