I believe the only reason to give this a label is so that you can enable
it in the dts. But I don't see the point of having it status disabled,
given that it should always follow the mdss node's status.

So my suggestion is to drop this and drop the label.

If not, please change the label of this node to mdss_mdp, for sorting
purposes.

Sorry, missed this one before sending my reply.

"kernel test robot" did not report the lack of mdss nodes in your dts.
So please drop this as well.

Please label this mdss_dsi0, to make it group nicely when sorted in the
dts.
