[libcamera-devel] [PATCH v4 1/4] libcamera: controls: Add SensorTemperature control

[Naushir Patuck]

Add a SensorTemperature control to return the temperature of the camera sensor
in Celsius. This control will only be present in the Request metadata if a
thermal sensor is available to the camera sensor.
