[libcamera-devel,RFC,0/6] Collect Camera properties

2324 mbox series

Hello,
  this series introduces libcamera Properties, which are generated re-using the
Control generation infrastructure, and implement creation of the location and
rotation property by inspecting the camera sensor v4l2 controls.

Sending as RFC mostly to get feedback on the generation of the Properties from
the property_ids.yaml file.

The series depends on the kernel patches that add camera properties as v4l2
controls and on the coreboot patches for the Soraka DSTD tables that add
LOCATION and ROTATION properties to the camera ACPI nodes.
