| 34 | |
| 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 |
| 37 | groups. |
| 38 | |
| 39 | The name of each subnode is not important; all subnodes should be enumerated |
| 40 | and processed purely based on their content. |
| 41 | |
| 42 | Required 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 | |
| 52 | Valid values for group names are: |
