Laurent,

I wanted to ask you about your comment here. I would agree that for
something like the OV5640 on the imx8mm-evk which is an add-in board
via a connector should be a dt overlay. I'm investigating using
overlays for features like this on my boards vs creating hierarchical
dts files and I see that the kernel allows building fragments with
'/plugin/' but I don't see any such overlays in the kernel tree
currently. Would overlay/fragments be accepted? Are there any examples
in the kernel tree already that I'm missing?

Best regards,

Tim
