| Initial multiplexer selection. |

| This must be in the range [0, N-1], where N is the length of the |
| 'devices' phandle list. |
| |
| If unspecified, the default selection is zero in order to ensure that |
| the multiplexer is ready for use (i.e. one of the [0, N-1] multiplexed |
| devices is selected). Zero is, necessarily, the only possible valid |
| default value since the phandle list must have length >= 1. |
| |
| Note: Specifying a value of 'selected' outside the range [0, N-1] |
| results in a compile-time error. |
