A new\npatch appears which is here to make it consistent.\n- v5 is a small rewording of the commit messages for 2/4 and 4/4.\n- v4 changes the way the structure is used in intel-ipu3.h to avoid\nany change in the buffer size. It should be transparent.\n\nPatch 1/5 moves the AWB structures to be able to use those from the\nipa::ipu3::algorithms namespace (by AGC at least).\n\nPatch 2/5 renames the stats region structure to make it clear it is an\naccumulator structure.\n\nPatch 3/5 is improving the Accumulator structure to have the same layout\nas the IPAFrameContext::awb structure.\n\nPatch 4/5 is removing the IPU3AwbCell from libcamera, and uses its\ndefinition directly from the kernel header.\n\nAnd if the cover letter has been read until here, there is no need to\npresent patch 5/5 ;-).\n\n\nJean-Michel Hautbois (5):\n ipa: ipu3: Move the AWB stats structures\n ipa: ipu3: Rename IspStatsRegion to Accumulator\n ipa: ipu3: Change Accumulator structure layout\n ipa: ipu3: Replace ipa::ipu3::algorithms::Ipu3AwbCell\n ipa: ipu3: awb: Make the naming consistant\n\n include/linux/intel-ipu3.h | 28 +++++++-\n src/ipa/ipu3/algorithms/agc.cpp | 7 +-\n src/ipa/ipu3/algorithms/awb.cpp | 120 +++++++++++++++++++++-----------\n src/ipa/ipu3/algorithms/awb.h | 30 +++-----\n 4 files changed, 122 insertions(+), 63 deletions(-)"}
