Merge tag 'pinctrl-for-v3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control changes from Linus Walleij:
 "These are the accumulated pin control patches for v3.6:
   - Various cleanups to the U300 driver
   - Refactor the pin control core to automatically remove any GPIO
     ranges when the drivers are removed, instead of having the drivers
     do this explicitly.
   - Add a function for registering a batch of GPIO ranges.
   - Fix a number of incorrect but non-regressive error checks.
   - Incremental improvements to the COH901, i.MX and Nomadik drivers
   - Add a one-register-per-pin entirely Device Tree-based pin control
     driver from Tony Lindgren."
