[libcamera-devel] [PATCH 0/5] libcamera: camera_sensor: Collect camera location and sizes

[Jacopo Mondi]

Hello, this small series add to the CameraSensor class informations on the
camera sensor location, the pixel array size and the active area sizes.

The information are required to populate the Android static metadata:
android.sensor.info.activeArraySize
android.sensor.info.pixelArraySize

and the 'struct camera_info.facing' flag.

Now that information are collected in the CameraSensor class, a way to expose
them through the Camera class is required. In example, adding the CameraSensor
that a Camera uses to the Camera class and collects all its Property in a single
properties vector might be the simplest way forward.

The series depends on the following kernel patch series:
https://patchwork.kernel.org/project/linux-media/list/?series=161169
https://patchwork.kernel.org/project/linux-media/list/?series=160901

Tested on IPU3 Soraka.
