Merge tag 'pinctrl-for-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pinctrl updates for v3.4 from Linus Walleij (*): - Switches the PXA 168, 910 and MMP over to use pinctrl - Locking revamped - Massive refactorings... - Reform the driver API to use multiple states - Support pin config in the mapping tables - Pinctrl drivers for the nVidia Tegra series - Generic pin config support lib for simple pin controllers - Implement pin config for the U300 * tag 'pinctrl-for-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (48 commits) ARM: u300: configure some pins as an example pinctrl: support pinconfig on the U300 pinctrl/coh901: use generic pinconf enums and parameters pinctrl: introduce generic pin config pinctrl: fix error path in pinconf_map_to_setting() pinctrl: allow concurrent gpio and mux function ownership of pins pinctrl: forward-declare struct device pinctrl: split pincontrol states into its own header pinctrl: include machine header to core.h ARM: tegra: Select PINCTRL Kconfig variables pinctrl: add a driver for NVIDIA Tegra pinctrl: Show selected function and group in pinmux-pins debugfs pinctrl: enhance mapping table to support pin config operations pinctrl: API changes to support multiple states per device pinctrl: add usecount to pins for muxing pinctrl: refactor struct pinctrl handling in core.c vs pinmux.c pinctrl: fix and simplify locking pinctrl: fix the pin descriptor kerneldoc pinctrl: assume map table entries can't have a NULL name field pinctrl: introduce PINCTRL_STATE_DEFAULT, define hogs as that state ... (*) What is it with all these Linuses these days? There's a Linus at google too. Some day I will get myself my own broadsword, and run around screaming "There can be only one". I used to be _special_ dammit. Snif.
