…arm/arm-soc

Pull arm soc-specific pinctrl changes from Olof Johansson:
 "With this, five platforms are moving to the relatively new pinctrl
  subsystem for their pin management, replacing the older soc specific
  in-kernel interfaces with common code.

  There is quite a bit of net addition of code for each platform being
  added to the pinctrl subsystem.  But the payback comes later when
  adding new boards can be done by only providing new device trees
  instead."

Fix up trivial conflicts in arch/arm/mach-ux500/{Makefile,board-mop500.c}

+
+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:
