There are cameras containing a mirror on their optical path e. g. when

How is this different from 'rotation = 180' ?
If you simply want to flip the output (e. g. horizontally), you cannot do this with a rotation.
The camera I'm referring to is not only upside down, but also flipped horizontally.

Introduce two options to change the device's flip property via device tree.

As there is already support for the panel-common driver [1], add it for cameras in the same way.
