It's the two most common use cases for imaging sensor temperature
measurements that I know of. My question to Benjamin is if he has the
same and/or other use cases.
Just like you said in a previous mail. This temperature sensor can be used to implement a retroactive loop from the host according to its value, such as noise correction for instance.
We don't have anything in the Linux user space that implements this yet, this was in anticipation.
So dropping it is fine, I will come back to it if need be ;)
When you implement this in userspace, you might want to consider situations
where the temperature is _not_ reported via media controls (which might
at least in theory happen if the temperature sensor is not part of the
v4l device), or for existing drivers with hwmon support
(drivers/media/i2c/video-i2c.c comes into mind).
