shouldn't this too calls be swapped ? I mean, some pm_runtime
implementations could be gating clocks at the driver's
->runtime_suspend() callback.

Perhaps.  I had added the explicit SLEEP/WAKEUP commands to
suspend()/resume(), but now I'm thinking issuing these commands should
not be the responsibility of the core, since the semantics of the
SLEEP/ACTIVE state aren't well defined in general (each
implementation/slave defines what, if anything, these states mean).

Fortunately, there are no users yet, so this is a painless change. :)

Thanks for taking a look.
