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:
