Enable IMX577 via CCI1 on LeMans EVK Core Kit.
The LeMans EVK board does not include a camera sensor
by default, this overlay reflects the possibility of
attaching an optional camera sensor.
For this reason, the camera sensor configuration is
placed in lemans-evk-camera.dtso, rather than
modifying the base lemans-evk.dts.

So, is it the only camera configuration that we are going to support?

It more precisely describes the content of the dtso. Thanks, Wenmeng

For example if you added another sensor to the mezzanine board on csi4 an ov9282 say lemans-evk-camera-csi4-ov9282.dtso The only problem with that is you can only enable the camera in one dtso But that feels like a problem to be solved only when someone upstreams more than one sensor for this mezzanine. --- bod
