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.
