It should be transparent. Patch 1/4 moves the AWB structures to be able to use those from the ipa::ipu3::algorithms namespace (by AGC at least). Patch 2/4 renames the stats region structure to make it clear it is an accumulator structure. Patch 3/4 is improving the Accumulator structure to have the same layout as the IPAFrameContext::awb structure. Patch 4/4 is removing the IPU3AwbCell from libcamera, and uses its definition directly from the kernel header.
