[PATCH v8 04/11] dt-bindings: drm/aux-bus: Add an example

From: Douglas Anderson
Date: Mon May 24 2021 - 20:03:16 EST


Now that we have an eDP controller that lists aux-bus, we can safely
add an example to the aux-bus bindings.

NOTE: this example is just a copy of the one in the 'ti-sn65dsi86'
one. It feels useful to have the example in both places simply because
it's important to document the interaction between the two bindings in
both places.

- Separate DP AUX bus binding is new for v8.
