device drivers should be smart enough to provide
->suspend/->resume callbacks when needed and they
should take care of doing whatever needs to be
done in order to allow a device to be suspended.

Calling pm_runtime_* from system suspend isn't
the right way to achieve that, as it creates a
situation where OMAP's PM has different requirements
and semantics than all other architectures.
