description:
|
|
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.
