  15   This binding file is a collection of the LVDS panels that
  16   has dual LVDS ports and requires only a single power-supply.
  17   The first port receives odd pixels, and the second port receives even pixels.
  18   There are optionally a backlight and an enable GPIO.
  19   The panel may use an OF graph binding for the association to the display,
  20   or it may be a direct child node of the display.
  21
  22   If the panel is more advanced a dedicated binding file is required.
