It should be transparent.\n\nPatch 1/4 moves the AWB structures to be able to use those from the\nipa::ipu3::algorithms namespace (by AGC at least).\n\nPatch 2/4 renames the stats region structure to make it clear it is an\naccumulator structure.\n\nPatch 3/4 is improving the Accumulator structure to have the same layout\nas the IPAFrameContext::awb structure.\n\nPatch 4/4 is removing the IPU3AwbCell from libcamera, and uses its\ndefinition directly from the kernel header. \n\n\nJean-Michel Hautbois (4):\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\n include/linux/intel-ipu3.h | 28 +++++++++++++--\n src/ipa/ipu3/algorithms/agc.cpp | 7 ++--\n src/ipa/ipu3/algorithms/awb.cpp | 61 ++++++++++++++++++---------------\n src/ipa/ipu3/algorithms/awb.h | 30 ++++++----------\n 4 files changed, 75 insertions(+), 51 deletions(-)"}
