Merge tag 'pinctrl-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pinctrl changes from Linus Walleij:
 "Some of this stuff is hitting arch/arm/* and have been ACKed by the
  ARM SoC folks, or it's device tree bindings pertaining to the specific
  driver.

  These are the bulk pinctrl changes for kernel v3.7:
   - Add subdrivers for the DB8540 and NHK8815 Nomadik-type ASICs,
     provide platform config for the Nomadik.
   - Add a driver for the i.MX35.
   - Add a driver for the BCM2835, an advanced GPIO expander.
   - Various fixes and clean-ups and minor improvements for the core,
     Nomadik, pinctr-single, sirf drivers.
   - Some platform config for the ux500."
