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." * tag 'sh-pinmux' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (81 commits) sh-pfc: sh_pfc_probe() sizeof() fix sh-pfc: Move sh_pfc.h from include/linux/ to driver directory sh-pfc: Remove pinmux_info definition sh: Remove unused sh_pfc_register_info() function sh: shx3: pinmux: Use driver-provided pinmux info sh: sh7786: pinmux: Use driver-provided pinmux info sh: sh7785: pinmux: Use driver-provided pinmux info sh: sh7757: pinmux: Use driver-provided pinmux info sh: sh7734: pinmux: Use driver-provided pinmux info sh: sh7724: pinmux: Use driver-provided pinmux info sh: sh7723: pinmux: Use driver-provided pinmux info sh: sh7722: pinmux: Use driver-provided pinmux info sh: sh7720: pinmux: Use driver-provided pinmux info sh: sh7269: pinmux: Use driver-provided pinmux info sh: sh7264: pinmux: Use driver-provided pinmux info sh: sh7203: pinmux: Use driver-provided pinmux info ARM: shmobile: sh73a0: Use driver-provided pinmux info ARM: shmobile: sh7372: Use driver-provided pinmux info ARM: shmobile: r8a7779: Use driver-provided pinmux info ARM: shmobile: r8a7740: Use driver-provided pinmux info ...
