Merge tag 'sh-pinmux' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull sh-mobile pinctrl conversion from Arnd Bergmann:
 "This is another cleanup series, containing the move of the Renesas
  SH-Mobile pin controller code from arch/arm/mach-shmobile over to the
  generic pinctrl subsystem, changing it over to the common interfaces
  in the process.

  Based on agreement between Olof, Paul Mundt, Linus Walleij and Simon,
  we're merging this large branch of pinctrl conversion through arm-soc,
  even though it contains the corresponding conversions for arch/sh.
  Main reason for this is tight dependencies (that will now mostly be
  broken) between the arch/sh and mach-shmobile implementations.

  There will be more of this in 3.10 to do device-tree bindings, but
  this is the initial conversion."
