This is in the wrong place now. Bjorn's suggestion for mdss_dp sounds good to me, and then putting the node in alphabetical order.

I'm also curious about the power domain for DP. My guess is that both DSI and DP nodes should be a child of mdss if they're in the display subsystem and powered down/inaccessible when the mdss_gdsc is disabled.
