2022-03-11ipa: ipu3: agc: Introduce lineDuration in IPASessionConfigurationJean-Michel Hautbois
Instead of having a local cached value for line duration, store it in the IPASessionConfiguration::sensor structure. While at it, configure the default analogue gain and shutter speed to controlled fixed values. The latter is set to be 10ms as it will in most cases be close to the one needed, making the AGC faster to converge.

The shutter speed limits and analogue gains limits are in the agc structure in IPASessionConfiguration. They are badly mentioned as being part of the grid structure, fix it.

2021-11-15ipa: ipu3: awb: Add support for color temperatureJean-Michel Hautbois
The AWB estimates the color temperature, but it is not used at all. It can be useful for debug purpose at least, but also for lux estimation later, to be able to know the temperature estimated for a given frame. Add a new member to the IPAFrameContext::awb for this purpose, and update the value in AWB.

2021-11-15ipa: ipu3: Use sensor controls to update frameContextJean-Michel Hautbois
The pipeline handler populates the new sensorControls ControlList, to have the effective exposure and gain values for the current frame. This is done when a statistics buffer is received. Make those values the frameContext::sensor values for the frame when the EventStatReady event is received. AGC also needs to use frameContext.sensor as its input values and frameContext.agc as its output values. Modify computeExposure by passing it the frameContext instead of individual exposure and gain values.

2021-10-26ipa: ipu3: ipa_context: Fix doxygen warningsKieran Bingham
The IPAFrameContext uses unnamed structures to group items. Doxygen doesn't seem to support this properly, documentation isn't properly generated and warnings are output during compilation. Suppress the warning with a workaround that still results in incorrect generated documentation until Doxygen gets fixed.

2021-10-26ipa: ipu3: Isolate ipa_context documentationKieran Bingham
The IPU3 IPA core is growing with additional documentation. The ipa_context documentation is stored here, but it pushes the IPU3 documentation and implementation further from the head of the file. Furthermore, the ipa_context documentation is outside of the ipa::ipu3 namespace and isn't identified correctly by Doxygen. Move the ipa_context to its own compilation object even though there isn't any code, but to maintain consistency with our documentation model. Correctly re-introduce the documentation into the libcamera::ipa::ipu3 namespace during the move.
