Here's what I think the regression fix for omap4 clocks would be, the old main_clk is not the same as the module clock that we get by default. If this looks OK I'll do a similar fix also for omap5.
Or is something else also needed?
hmm, audio output works, the waring is away, but something new is here:
OK good to hear it works, I'll send out fixes for omap4 and 5, seems the runtime PM warning is something different.
omap-mcbsp 40124000.mcbsp: Runtime PM usage count underflow! # cat /sys/bus/platform/devices/40124000.mcbsp/power/runtime_status active
even with no sound.
I guess if the mcbsp instance is not used, runtime PM is enabled but pm_runtime_resume_and_get() is never called by ASoC?
If so then the following might be a fix, not familiar with runtime PM done by ASoC though and not sure if some kind of locking would be needed here.
just checked: that one fixes the regression. runtime suspends again.
