title: DisplayPort AUX bus
- Douglas Anderson <>
DisplayPort controllers provide a control channel to the sinks that
are hooked up to them. This is the DP AUX bus. Over the DP AUX bus
we can query properties about a sink and also configure it. In
particular, DP sinks support DDC over DP AUX which allows tunneling
a standard I2C DDC connection over the AUX channel.
To model this relationship, DP sinks should be placed as children
of the DP controller under the "aux-bus" node.
At the moment, this binding only handles the eDP case. It is
possible it will be extended in the future to handle the DP case.
For DP, presumably a connector would be listed under the DP AUX
bus instead of a panel.
