As jack detection can trigger DAPM and the latency in debouncing can create confusing windows in operation provide some trace events which will hopefully help in diagnostics. The soc-jack core traces all reports that it gets and the resulting notifications to upper layers. An event for jack IRQs is also provided for instrumentation of debounce, and used in the GPIO jack code.
