+
+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:
