[PATCHv4 0/7] Add pinctrl driver for Allwinner A1X SoCs

[Maxime Ripard]

Hi everyone,

This patch set adds a pinctrl driver for the IP found in the Allwinner A10
and A13, and the SoC-specific bits for the A13. It also adds the documentation
for the device tree bindings.

This patch set has been tested on a Olimex A13-Olinuxino.

Thanks,
Maxime

Changes from v3:
  - Replaced the bitmasks computation by a define
  - Removed the __devinit
  - Added boundary check on drive levels

Changes from v2:
  - Rebased on top of 3.8-rc2
  - Changed the name of the pinconf argument, split the change to
    pinconf-generic.h to a separate patch, and documented the argument

Changes from v1:
  - Uses the pinconf-generic mechanism
  - Changed the dt interface to remove the direct bitstuffing to a more
    readable format
  - Replaced the register accessor macros by inline functions and documented
    them
