Hello,

This small patch series improves metadata reporting in IPA modules by
making it possible for individual algorithms to report metadata, instead
of relying on the top-level IPA module code to do so.

Patch 1/3 extends the Algorithm::process() function to take a metadata
contro list argument that algorithms should fill with metadata for the
frame. Patch 2/3 updates the RkISP1 AGC and AWB algorithms to report
their metadata, and patch 3/3 does the same for the IPU3 IPA module.

Laurent Pinchart (3):
  ipa: Pass metadata to Algorithm::process() function
  ipa: rkisp1: Fill AGC and AWB metadata
  ipa: ipu3: Fill AGC and AWB metadata in algorithms
