[libcamera-devel] [PATCH 00/13] Support SensorTimestamp metadata

[Jacopo Mondi]

Hello,
  v2 grow quite significatively compared to v1 :/

Reason is that now all the pipeline handlers report SensorTimestamp, each
one with its own specificities.

Here and there a few drive-by fixes, and two patches for cam to add support
for listing all the metadata associated with a completed Request.

v1->v2:
- controls: Refer to CLOCK_BOOTTIME explicitely
- pipeline:
  - Add support for SensorTimestamp in all pipelines
- HAL
  - Assume SensorTimestamp is always available.

In future, it might be beneficial to add to lc-compliance a test to make
sure SensorTimestamp is reported. Maybe a 'mandatory' flag can be added to
the controls definition for that purpose.

Thanks
