I'm fine with that.

DT is based on the actual HW construction, not how a particular OS wants
to expose that HW through its APIs. If there is a single HW block, there
should be a single DT node, even if that HW block supports multiple
channels.

In some circumstances, it might make sense for the single top-level node
that represents the HW-block to have child nodes that represent the
channels, depending on what exactly the HW is doing and whether this
level of detail is useful in DT. I would qualify this as rare though.
