I'm sorry for those suggestions, I don't like either one of them.

And for everything but changes to the DRM code the changelog goes below
the --- line, so it's not part of the git history.

Is it a limitation of the EC in Trogdor that you can only do 2 lanes?

If you label this "mdss_dp", then it will naturally group with other
mdss properties in trogdor.dtsi (which should be sorted alphabetically).

Just curious, but isn't the DP block in the MDSS_GDCS? Or do we need to

Maybe name it dp_opp_table instead?
