| |
Devices that have both single-ended channels and differential channels cause a bit of confusion when the channels are configured in the devicetree.
Clarify difference between these two types of channels for such devices by adding single-channel property alongside diff-channels. They should be mutually exclusive.
Devices that have only single-ended channels can still use reg property to reference a channel like before.
