Merge tag 'pinctrl-v3.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control changes from Linus Walleij:
 "This is the bulk of pin control changes for the v3.18 development
  series:

   - New drivers for the Freescale i.MX21, Qualcomm APQ8084 pin
     controllers.

   - Incremental new features on the Rockchip, atlas 6, OMAP, AM437x,
     APQ8064, prima2, AT91, Tegra, i.MX, Berlin and Nomadik.

   - Push Freescale drivers down into their own subdirectory.

   - Assorted sprays of syntax and semantic fixes"
