| Number of receive channels enabled on this instance. |
| Setting this value to N, will enable channels 0 to N-1, consecutively. |
| It should be set by the receiver core coupled with this MU instance. |
| |
| For example, if receiver A wants to Rx on channels 0 to 3, then A must |
| set rx-channels of muA as follows: |
| |
| mruA { |
| rx-channels = <4>; |
| status = "okay"; |
| }; |
