Merge branch 'drm-next-merged' of git://people.freedesktop.org/~airlied/linux into v4l_for_linus

That solves several merge conflicts: Documentation/DocBook/media/v4l/subdev-formats.xml Documentation/devicetree/bindings/vendor-prefixes.txt drivers/staging/media/mn88473/mn88473.c include/linux/kconfig.h include/uapi/linux/media-bus-format.h The ones at subdev-formats.xml and media-bus-format.h are not trivial. That's why we opted to merge from DRM.

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.
