These are the main pinctrl changes for the v3.9 merge window:

- 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.
