The above sounds to me like the panel-specific compatible string implies the LVDS binding, in a way that many compatible strings imply the simple binding. Note that initially we did the very same thing with "panel-simple", only to realize that it's completely redundant because it is never used. > +- width-mm: See panel-common.txt. > +- height-mm: See panel-common.txt. > +- data-mapping: The color signals mapping order, "jeida-18", "jeida-24" > + or "vesa-24". > + > +Optional properties: > + > +- label: See panel-common.txt. > +- gpios: See panel-common.txt. > +- backlight: See panel-common.txt. > +- data-mirror: If set, reverse the bit order described in the data mappings > + below on all data lanes, transmitting bits for slots 6 to 0 instead of > + 0 to 6. > + > +Required nodes: > + > +- panel-timing: See panel-common.txt. > +- ports: See panel-common.txt.
