Hi Jacopo,

Thank you for the patch.

As explained in my review of patch 5/7, I'd merge 5/7, 6/7 and 7/7 all 
together as there's little use for enabling the LVDS decoder if there's 
nothing connected at its output. Note also how this patch alone, without 7/7, 
wouldn't comply with the LVDS decoder DT bindings that state that port at 2 is 
mandatory.
