[libcamera-devel] [PATCH v3 0/9] Use two imgus in ipu3 pipeline handler

[Harvey Yang]

Hello everyone,

This is the third version of patches to use two imgus in ipu3 pipeline
handler, mostly to better support StillCapture, which was handled as
video snapshot.

The 8th patch is updated to fall back to the original logic when the
StillCapture stream is rejected in the pipeline handler.

The patches are tested on soraka.
Please take a look and give me your thoughts. Thanks!

BR,
Harvey
