34
35SPEAr's pinmux nodes act as a container for an arbitrary number of subnodes. Each
36of these subnodes represents muxing for a pin, a group, or a list of pins or
37groups.
38
39The name of each subnode is not important; all subnodes should be enumerated
40and processed purely based on their content.
41
42Required 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
52Valid values for group names are:
