35 SPEAr's pinmux nodes act as a container for an arbitrary number of subnodes. Each
36 of these subnodes represents muxing for a pin, a group, or a list of pins or
39 The name of each subnode is not important; all subnodes should be enumerated
40 and processed purely based on their content.
42 Required subnode-properties:
43 - st,pins : An array of strings. Each string contains the name of a pin or
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.
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
52 Valid values for group names are:
