There should be nothing against that - provided ALSA's needs remain
similar to the current set of actions (regulators, gpios, ...) it
should be perfectly usable. Can you think of any usage that involves
more than dumb regulator/gpio manipulation?

If power seqs are to be used this way (as opposed to through the DT),
it will become urgent to implement that gpio handlers library we were
talking about in another thread, as we don't want to have GPIO numbers
hard-coded into the sequences.
