2023-03-28ipa: raspberrypi: Add sensor mode limits to CameraModeNaushir Patuck
Add fields in the CameraMode structure to capture the mode specific limits for analogue gain and shutter speed. For convenience, also add fields for minimum and maximum frame durations. Populate these new fields when setting up the CameraMode structure.

2022-10-18ipa: raspberrypi: Add minimum and maximum line length fields to CameraModeNaushir Patuck
Add fields for minimum and maximum line length duration to the CameraMode structure. This replaces the existing lineLength field. Any use of the existing lineLength field is replaced by the new minLineLength field, as logically we always want to use the fastest sensor readout by default. As a drive-by cosmetic change, split all fields in the CameraMode structure into separate lines.

2021-02-05ipa: raspberrypi: Limit the calculated vblank based on the sensor modeNaushir Patuck
The existing framerate/vblank calculations did not account for the sensor mode limits. This commit extracts vblank limits from the sensor v4l2 controls, and stores it in the camera modes structure. Exposure and vblank value calculations now use values clamped to the sensor mode limits. The libcamera::controls::FrameDurations metadata return values now reflect the minimum and maximum after clamping.

2020-09-29libcamera: raspberrypi: Plumb user transform through to IPADavid Plowman
This commit plumbs the user transform from the Raspberry Pi pipeline handler through to the IPA. Note that the transform is actually handled in the sensor (by setting the h/v flip bits), so the IPAs need to understand the orientation of the image they receive. Once in the IPA we add it to the CameraMode description, so that it becomes automatically available to all the individual control algorithms. The IPA configure method has to be reordered just a little so as to fill in the transform in the camera mode before calling SwitchMode.
