I finally found some time to looks at this.

The bindings does unfortunately not pass a dt_binding_check

I had to locally do the following to make on of the bindings pass:
diff --git a/Documentation/devicetree/bindings/display/panel/auo,b101uan08.3.yaml b/Documentation/devicetree/bindings/display/panel/auo

I will follow-up with review feedback on the drivers later as time
permits.
