|
|
SPEAr's pinmux nodes act as a container for an arbitrary 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:
