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."
