14 are hooked up to them. This is the DP AUX bus. Over the DP AUX bus
16 particular, DP sinks support DDC over DP AUX which allows tunneling
19 To model this relationship, DP sinks should be placed as children
20 of the DP controller under the "aux-bus" node.
23 possible it will be extended in the future to handle the DP case.
