Pardon for the late reply.

As mentioned in another email, if you're interested in reusing the drm
panel infrastructure you should be looking in
Documentation/devicetree/bindings/display/panel/. With display-timing
panel-dpi panel-dsi-cm and (optional) simple-panel as a start.

Would reshuffling/documenting things make it more obvious ? Feel free
to let Rob Herring, Thierry Reding know.

Regards,
Emil
