2021-02-05ipa: raspberrypi: Pass the maximum allowable shutter speed into the AGCNaushir Patuck
In order to provide an optimal split between shutter speed and gain, the AGC must know the maximum allowable shutter speed, as limited by the maximum frame duration (either application provided or the default). Add a new API function, SetMaxShutter, to the AgcAlgorithm class. The IPA provides the maximum shutter speed for AGC calculations. This applies to both the manual and auto AGC modes.

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.

2021-02-02ipa: raspberrypi: Warn when control algorithms are missing; do not failDavid Plowman
Users are free to avoid loading certain control algorithms from the json tuning file if they wish, and this could mean that some libcamera controls will therefore not be available. Currently we don't have a good means of indicating which these are, therefore failing completely when an application tries to use one is unhelpful - it is better just to issue a warning. Note that once we can indicate this properly, applications should check for supported controls as this change may be reverted.

Previously the CamHelper was returning the number of frames to drop (on account of AGC/AWB converging). This wasn't really appropriate, it's better for the algorithms to do it as they know how many frames they might need. The CamHelper::HideFramesStartup method should now just be returning the number of frames to hide because they're bad/invalid in some way, not worrying about the AGC/AWB. For many sensors, the correct value for this is zero. But the ov5647 needs updating as it must return 2.
