Merge branch 'spear/pinctrl' into next/pinctrl 

This is a rebased version of some contents of
  git://git.stlinux.com/spear/linux-2.6.git

 spear-v3.5
which was accidentally sent against linux-next rather than an
-rc release.

The commits are based on other changes in the spear/dt branch
of the arm-soc tree that they depend on.

* spear/pinctrl:
  SPEAr3xx: Add pinctrl support for boards
  SPEAr: Remove existing padmux support for SPEAr
  pinctrl: Add SPEAr3xx pinctrl drivers
  pinctrl: Add SPEAr pinctrl drivers

SPEAr's pinmux nodes act as a container for an abitrary number of subnodes. Each

of these subnodes represents muxing for a pin, a group, or a list of pins or

groups.



The name of each subnode is not important; all subnodes should be enumerated

and processed purely based on their content.



Required subnode-properties:

- st,pins : An array of strings. Each string contains the name of a pin or

  group.

- st,function: A string containing the name of the function to mux to the pin or

  group. See the SPEAr's TRM to determine which are valid for each pin or group.



  Valid values for group and function names can be found from looking at the

  group and function arrays in driver files:

  drivers/pinctrl/spear/pinctrl-spear3*0.c



Valid values for group names are:

For All SPEAr3xx machines:
