To me it makes sense to manage the clocks and reset from the same place. Currently we have the clocks management moved completely into runtime PM fsl_sai_runtime_resume and fsl_sai_runtime_suspend callbacks.
Usually the pattern is to have probe() leave everything powered up then let runtime PM power things down if it's enabled, you can often do the power up by having an open coded call to the resume callback in probe().
It seems some drivers very depend on runtime PM, if the CONFIG_PM=n, the drivers should not work. What's the strategy for this? Do we need to support both cases, or only one case is also acceptable?
