Merge tag 'pinctrl-for-v3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control changes from Linus Walleij:

 - A large slew of improvements of the Genric pin configuration support,
   and deployment in four different platforms: Rockchip, Super-H PFC,
   ABx500 and TZ1090.  Support BIAS_BUS_HOLD, get device tree parsing
   and debugfs support into shape.

 - We also have device tree support with generic naming conventions for
   the generic pin configuration.

 - Delete the unused and confusing direct pinconf API.  Now state
   transitions is *the* way to control pins and multiplexing.

 - New drivers for Rockchip, TZ1090, and TZ1090 PDC.

 - Two pin control states related to power management are now handled in
   the device core: "sleep" and "idle", removing a lot of boilerplate
   code in drivers.  We do not yet know if this is the final word for
   pin PM, but it already make things a lot easier to handle.

 - Handle sparse GPIO ranges passing a list of disparate pins, and
   utilize these in the new BayTrail (x86 Atom SoC) driver.

 - Make the sunxi (AllWinner) driver handle external interrupts.

 - Make it possible for pinctrl-single to handle the case where several
   pins are managed by a single register, and augment it to handle sleep
   modes.

 - Cleanups and improvements for the abx500 drivers.

 - Move Sirf pin control drivers to their own directory, support
   save/restore of context and add support for the SiRFatlas6 SoC.

 - PMU muxing for the Dove pinctrl driver.

 - Finalization and support for VF610 in the i.MX6 pinctrl driver.

 - Smoothen out various Exynos rough edges.

 - Generic cleanups of various kinds.
