+description: |
+ The ANX7688 bridge describes the HDMI 2.0 to DisplayPort 1.3 bridge block
+ included in the ANX7688 chip controller. These are meant to be used for
+ controlling display-related signals.
+
+ The node of this device should be under an analogix,anx7866 node. Please refer
+ to Documentation/devicetree/bindings/mfd/analogix,anx7688.yaml for the ANX7688
+ core bindings.
