This is the DP AUX bus. Over the DP AUX bus15 we can query properties about a sink and also configure it. In16 particular, DP sinks support DDC over DP AUX which allows tunneling17 a standard I2C DDC connection over the AUX channel.18 19 To model this relationship, DP sinks should be placed as children20 of the DP controller under the "aux-bus" node.21 22 At the moment, this binding only handles the eDP case. It is23 possible it will be extended in the future to handle the DP case.24 For DP, presumably a connector would be listed under the DP AUX25 bus instead of a panel.26 27properties:28 $nodename:29 const: aux-bus30 31 panel:32 $ref: panel/panel-common.yaml#33 34additionalProperties: false35 36required:37 - panel38
