So this is done from cpuidle rather than system suspend.

It is done for system suspend. It isn't possible to do this in a
cpuidle use case as the memory controller would need to come out of
idle automatically to service DMA requests.

OK, so it's all part of the core power down sequence for the SoC?  I'm
not sure that makes a big difference but it at least means that there
are fewer runtime interactions to worry about.

I mean describe the intended sequence of events in the system rather
than the raw register commands to accomplish them.

I'm still not sure what you mean.

Say "set voltage X" or even "regulator X supplies Y" not "send this
bytestream to the device".
