2020-08-05libcamera: ipa: raspberrypi: ALSC: Improve behaviour when camera mode changesDavid Plowman
Now that we stop the asynchronous thread on a SwitchMode, we would do better to regenerate all the tables if the new camera mode crops in a significantly different way to the old one. A few minor tweaks make sense along with this: * Reset the lambda values when we reset everything. It wouldn't make sense to re-start with the old mode's values. * Use the last recorded colour temperature to generate new tables rather than any default value. * Set the frame "phase" counter to ensure the adaptive procedure will run asap.

2020-08-05libcamera: ipa: raspberrypi: ALSC: Resample luminance tableDavid Plowman
This fixes a bug where the luminance correction table was not being resampled according to the camera mode, in the same way as the colour tables. This could be noticeable if any camera modes crop aggressively. This resampling can be done "up front" in the SwitchMode, as we have only a single fixed luminance table. In order to protect the recalculation of the table from the asynchronous thread (which reads it) I've elected to wait for that thread to go idle (though I doubt it would have mattered much). As a by-product of stopping the thread, it no longer needs its own copy of the camera mode (async_camera_mode_).

The assignStream() implementation also assumes only full-size streams can be produced by the main output, and having it as a separate function prevents adjusting streams according to which output they are assigned.
