Merge tag 'pinctrl' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull arm soc-specific pinctrl changes from Olof Johansson: "With this, five platforms are moving to the relatively new pinctrl subsystem for their pin management, replacing the older soc specific in-kernel interfaces with common code. There is quite a bit of net addition of code for each platform being added to the pinctrl subsystem. But the payback comes later when adding new boards can be done by only providing new device trees instead." Fix up trivial conflicts in arch/arm/mach-ux500/{Makefile,board-mop500.c} * tag 'pinctrl' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (61 commits) mtd: nand: gpmi: fix compile error caused by pinctrl call ARM: PRIMA2: select PINCTRL and PINCTRL_SIRF in Kconfig ARM: nomadik: enable PINCTRL_NOMADIK where needed ARM: mxs: enable pinctrl support video: mxsfb: adopt pinctrl support ASoC: mxs-saif: adopt pinctrl support i2c: mxs: adopt pinctrl support mtd: nand: gpmi: adopt pinctrl support mmc: mxs-mmc: adopt pinctrl support serial: mxs-auart: adopt pinctrl support serial: amba-pl011: adopt pinctrl support spi/imx: adopt pinctrl support i2c: imx: adopt pinctrl support can: flexcan: adopt pinctrl support net: fec: adopt pinctrl support ARM: ux500: switch MSP to using pinctrl for pins ARM: ux500: alter MSP registration to return a device pointer ARM: ux500: switch to using pinctrl for uart0 ARM: ux500: delete custom pin control system ARM: ux500: switch over to Nomadik pinctrl driver ...
