I think I will go with this re-phrasing of the commit message:
ipa: ipu3: Replace event-based ops with dedicated functions
The IPAIPU3 interface currently uses event-type based structures in
order to communicate with the pipeline-handler (and vice-versa).
Replace the event based structures with dedicated functions associated
to each operation.
The translated naming scheme of actions to signals are:
ActionSetSensorControls => setSensorControls
ActionParamFilled => paramsBufferReady
ActionMetadataReady => metadataReady
The translated naming scheme of events to dedicated functions are:
EventProcessControls => queueRequest()
EventStatReady => processStatsBuffer()
EventFillParams => fillParamsBuffer()
The dedicated functions are called from pipeline-handler to the IPA
using IPC. These functions run asynchronously and when completed,
the IPA emits the respective signals as stated above in the translated
naming scheme.
The EventProcessControls is translated to queueRequest() to bring
symmetry to the IPU3 interface with other IPA interfaces.
