| 18 | Description |
| 19 | ----------- |
| 20 | |
| 21 | The pinmux command is used to show the pin-controller muxing. |
| 22 | |
| 23 | The 'pinmux list' command diplays the available pin-controller. |
| 24 | |
| 25 | The 'pinmux dev' command selects the pin-controller for next commands. |
| 26 | |
| 27 | pincontroller-name |
| 28 | name of the pin-controller to select |
| 29 | |
| 30 | The 'pinmux status' command displays the pin muxing information. |
| 31 | |
| 32 | \-a |
| 33 | display pin muxing of all pin-controllers. |
| 34 | pin-name |
| 35 | name of the pin to display |
| 36 | |

| 89 | Configuration |
| 90 | ------------- |
| 91 | |
| 92 | The pinmux command is only available if CONFIG_CMD_PINMUX=y. |
| 93 | |
| 94 | Return value |
| 95 | ------------ |
| 96 | |
| 97 | The return value $? is set to 0 (true) if the command succeded and to 1 (false) |
| 98 | otherwise. |
