| |
| 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: |
