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."
