Hi Miquel.

I have applied this.
Can you please re-do patch 2/3 so the compatible is added to
panel-simple.yaml - which I just pushed to drm-misc-next.

Then we have a two-line entry rather than a whole file
as you also asked for.

Great! I think it's much better like this. Let's drop patch 2/3, I'm
re-sending 2/3 (updated) and 3/3 (no changes).

Thanks,
