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."
