35 SPEAr's pinmux nodes act as a container for an
36 of these subnodes represents muxing for a pin,
37 groups.
38
39 The name of each subnode is not important; all
40 and processed purely based on their content.
41
42 Required subnode-properties:
43 - st,pins : An array of strings. Each string c
44 group.
45 - st,function: A string containing the name of
46 group. See the SPEAr's TRM to determine whic
