This patchset has been grown out of:
[PATCH v2] ipa: ipu3: Add a IPAFrameContext queue
and now consolidates that change here itself.

The main changes are :
- Remove event passing b/w PH <> IPA and use dedicated
  functions 2/4
- Introduce a queue-lookup for preserved frame-contexts 4/4

Patch 3/4 has been manually cherry-picked by JM's earlier work.

Series has been CTS-verified on LIMITED level. No regressions seen.

Jean-Michel Hautbois (1):
  ipa: ipu3: Mark the beginning and end of a frame

Umang Jain (3):
  libipa: algorithm: Pass frame number to prepare() and process()
  ipa: ipu3: Replace event-based operations with dedicated functions
  ipa: ipu3: Add a IPAFrameContext queue
