2024-06-19libcamera: debayer_cpu: Add 32bits/aligned output formatsRobert Mader
In order to be more compatible with modern hardware and APIs. This notably allows GL implementations to directly import the buffers more often and seems to be required for Wayland. Further more, as we already enforce a 8 byte stride, these formats work better for clients that don't support padding - such as libwebrtc at the time of writing.

2024-06-17ipa: rkisp1: agc: Correctly clamp maximum shutter speedLaurent Pinchart
The sensor's maximum shutter speed is clamped by the maximum frame duration specified in requests. If the requested maximum frame duration is lower than the sensor's minimum shutter speed, the Agc::process() function will pass a minimum value higher than the maximum to the setLimits() function, resulting in an assertion failure. Fix it by clamping the value to both the lower and the upper bounds.

generateConfiguration() called validate() as a final step, causing the stride and frameSize fields in StreamConfiguration to be filled in based on the pixel format and width/height. If a user application did not clear the stride field when setting up a custom pixel format and width/height, the pipeline handler would respect this stride and possibly overallocate buffers with a larger stride than needed. Fix this by removing the call to validate() completely, leaving the stride and frameSize fields defaulting to 0. Removal of this call is inconsequential as we hard-code a valid configuration for Raspberry Pi platforms in generateConfiguration().
