You mean this piece of doc? Indeed looks inaccurate. I'll update it.
Wait, no, this is correct. Please point to what is wrong in kernel doc. I don't see it. :(
the TRIGGER_STOP and TRIGGER_PAUSE_PUSH do the same thing. There is no specific mapping of disable() to TRIGGER_STOP and unprepare() to TRIGGER_PAUSE_PUSH as the documentation hints at.
Which TRIGGER_STOP and TRIGGER_PAUSE_PUSH? In one specific codec driver? If yes, I don't think Slimbus documentation should care how actual users implement it (e.g. coalesce states).
In both of the patches you just modified :-)

the bus provides helpers to be used in well-defined transitions. A codec driver doing whatever it wants whenever it wants would create chaos for the bus.
