2022-10-01ipa: rkisp1: Remove initialized_ flags from algorithmsLaurent Pinchart
Multiple algorithms have an initialized_ flag that they set to true at the end of the init() function, and check at the beginning of prepare() to skip preparation. This serves no real purpose, as the flag can only be false if init() fails, in which case the IPA module initialization as a whole will fail. Drop the initialized_ flags.

2022-09-28ipa: rkisp1: Use frame number passed to Algorithm::prepare()Laurent Pinchart
Now that the Algorithm::prepare() function takes a frame number, we can use it to replace the IPAActiveState::frameCount member.

2022-09-28ipa: rkisp1: Rename frameContext to activeStateKieran Bingham
The RkISP1 IPA module creates a single instance of its IPAFrameContext structure, effectively using it more as an active state than a per-frame context. To prepare for the introduction of a real per-frame context, move all the members of the IPAFrameContext structure to a new IPAActiveState structure. The IPAFrameContext becomes effectively unused at runtime, and will be populated back with per-frame data after converting the RkISP1 IPA module to using a frame context queue. The IPAActiveState structure will slowly morph into a different entity as individual algorithm get later ported to the frame context API. While at it, fix a typo in the documentation of the Agc::computeExposure() function that incorrectly refers to the frame context instead of the global context.
