Re: [PATCH v2 2/3] dt-bindings: drm/bridge: ps8640: Add aux-bus child

Quoting Philip Chen (2021-09-29 17:34:57)

dp-aux-bus.yaml says we can list an eDP panel as a child of
an eDP controller node to represent the fact that the panel
is connected to the controller's DP AUX bus.

Let's add it to the ps8640 bindings.
