A panel with dual LVDS interfaces is no longer in the "simple" category.
The panel-simple binding shall be limited to the simple pnales only.
This is also why we have for example panel-simple-dsi binding.
Please consider either a binding dedicated for the dual port displays or
a dedicated binding for the specific panel.
I trust that if other readers of this mail disagrees with this
recommendation that they will speak up.
