 LVDS Channel
 ============
 
-Each LVDS Channel has to contain a display-timings node that describes the
-video timings for the connected LVDS display. For detailed information, also
-have a look at Documentation/devicetree/bindings/video/display-timing.txt.
+Each LVDS Channel has to contain either an of graph link to a panel device node
+or a display-timings node that describes the video timings for the connected
+LVDS display as well as the fsl,data-mapping and fsl,data-width properties.
 
 Required properties:
  - reg : should be <0> or <1>
+ - port: Input and output port nodes with endpoint definitions as defined in
+   Documentation/devicetree/bindings/graph.txt.
+   On i.MX5, the internal two-input-multiplexer is used. Due to hardware
+   limitations, only one input port (port@[0,1]) can be used for each channel
+   (lvds-channel@[0,1], respectively).
+   On i.MX6, there should be four input ports (port@[0-3]) that correspond
+   to the four LVDS multiplexer inputs.
+   A single output port (port@2 on i.MX5, port@4 on i.MX6) must be connected
+   to a panel input port. Optionally, the output port can be left out if
+   display-timings are used instead.
+
+Optional properties (required if display-timings are used):
+ - display-timings : A node that describes the display timings as defined in
+   Documentation/devicetree/bindings/video/display-timing.txt.
  - fsl,data-mapping : should be "spwg" or "jeida"
                       This describes how the color bits are laid out in the
                       serialized LVDS signal.
  - fsl,data-width : should be <18> or <24>
- - port: A port node with endpoint definitions as defined in
-   Documentation/devicetree/bindings/media/video-interfaces.txt.
-   On i.MX5, the internal two-input-multiplexer is used.
-   Due to hardware limitations, only one port (port@[0,1])
-   can be used for each channel (lvds-channel@[0,1], respectively)
-   On i.MX6, there should be four ports (port@[0-3]) that correspond
-   to the four LVDS multiplexer inputs.
