Merge tag 'pinctrl-v3.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control changes from Linus Walleij:
 "Here is a stash of pin control changes I have collected for the v3.19
  series.  Mainly new hardware support, with Intels new embedded SoC as
  the especially interesting thing standing out, fully using the
  subsystem.

   - Force conversion of the ux500 pin control device trees and parsers
     to use the generic pin control bindings.
   - New driver and device tree bindings for the Qualcomm PMIC MPP pin
     controller and GPIO.
   - Some ACPI infrastructure for pin controllers.
   - New driver for the Intel CherryView/Braswell pin controller, the
     first Intel pin controller to fully take advantage of the pin
     control subsystem.
   - Support the Freescale i.MX VF610 variant.
   - Support the sunxi A80 variant.
   - Support the Samsung Exynos 4415 and Exynos 7 variants.
   - Split out Intel pin controllers to their own subdirectory.
   - A large slew of rockchip pin control updates, including
     suspend/resume support.
   - A large slew of Samsung Exynos pin controller updates.
   - Various minor updates and fixes"
