In MHU the 32bits are tied together and all go to one target
processor. Whereas on QCom, each bit corresponds to independent signal
going to a different target processor.

I was not aware of that. Thanks for clarifying the differences.

IOW, QCom has 32 channels per register whereas MHU has one. The

OK, that depends on how we consider it. As you said yes it just goes to
single target processor, but hardware designers consider it still 32
channels are they can be controller independently without any locking.

MHU spec says it has three channels.
Locking is not a criterion for a channel. A signal and associated data
transfer defines a channel.
