This set of patches adds:

* Add pinctrl-single for handling Padconf registers.
* Add NAND node to export NAND functionality on da850 EVM.
* Add NAND pinctrl node to do pin mux according to pinctrl-single driver.


This series applies on top of tag next-20130107 git tree
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
and the following patch

 -drivers/pinctrl: grab default handles from device core
  https://patchwork.kernel.org/patch/1862231/

This series is tested on da850 EVM.

Changes since V2:

 -Move NAND pins configuration into the nand_cs3 DT node to avoid pins
  configuration if it is not probed. 

Changes since V1:

 -Remove the binding documentation as already documented as part of
  Documentation/devicetree/bindings/pinctrl/pinctrl-single.txt
 -Enable PINCTRL Kconfig for MACH_DA8XX_DT platform only.
 -Fix the pinctrl driver node unit-address.
 -Make separate patch for da8xx_omapl_defconfig changes.

For DT, DaVinci platform can use pinctrl-single driver for handling
padconf registers.

Enable PINCTRL Kconfig for MACH_DA8XX_DT platform. Add required
pinctrl DT entries in da850 dts file.

 Test procedure
  1)Populate DT file with NAND node information.
  2)Populate board DT file with pinmux information for NAND.
  3)Boot and confirm NAND is detected by the kernel.
  4)cat /proc/mtd to show partitions.

Please do not spin versions so fast. Give some reasonable time for
discussion to close before you send a new version. Dont want to see a
flood of versions. It creates confusion.
