Merge tag 'pinctrl-for-v3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pinctrl changes from Linus Walleij:
"These are the main pinctrl changes for the v3.9 merge window. The
most interesting change by far is how the device core grabs pinctrl
default handles avoiding the need to stick boilerplate into driver
consumers.
- Grabbing of default pinctrl handles from the device core. These
are the hunks hitting drivers/base. All is ACKed by Greg, after a
long discussion about different alternatives.
- Some stuff also touches the MFD and ARM SoC trees, this has been
coordinated and ACKed.
- New drivers for:
- The Tegra 114 sub-SoC
- Allwinner sunxi
- New ABx500 driver and sub-SoC drivers for AB8500, AB8505, AB9540
and AB8540.
- Make it possible for hogged pins to enter a sleep mode, and make it
possible for drivers to control that mode.
- Various clean-up, extensions and device tree support to various pin
controllers."
