The HDMI encoder is connected to the RGB output of the DU, which is
port@0, not port@1. Fix the incorrect DT description.

Should this have the following tag?

Fixes: c5af8a4248d3 ("ARM: dts: porter: add DU DT support")

If so, is it a fix to apply for v4.15 or a more regular patch
to apply for v4.16?

That would make sense, yes.

I believe we can wait for v4.16. HDMI output works on Porter at the moment due 
to a separate bug in the DU driver that clones outputs by default when it 
shouldn't. There's however no harm in backporting the patch to stable series 
if desired, but it's not required.

Thanks, I've applied this for v4.16 with the fixes tag above.
Possibly the fixes tag will result in some automated backporting occurring.
If so we can let that run its course, if not we can leave things be with
the option to backport later if we decide its necessary.

I have not applied the other dts patches in this series at this point.
