33	pinctrl bindings used by client devices.
34	
35	SPEAr's pinmux nodes act as a container for an abitrary number of subnodes. Each
36	of these subnodes represents muxing for a pin, a group, or a list of pins or
37	groups.
38	
39	The name of each subnode is not important; all subnodes should be enumerated
40	and processed purely based on their content.
41	
42	Required subnode-properties:
43	- st,pins : An array of strings. Each string contains the name of a pin or
44	  group.
45	- st,function: A string containing the name of the function to mux to the pin or
46	  group. See the SPEAr's TRM to determine which are valid for each pin or group.
47	
48	  Valid values for group and function names can be found from looking at the
49	  group and function arrays in driver files:
50	  drivers/pinctrl/spear/pinctrl-spear3*0.c
51	
52	Valid values for group names are:
