What ist the standard way to define connector type and bus format with device tree?

[H. Nikolaus Schaller]

Hi,
according to bindings/display/panel/panel-common.yaml
and by using "panel-simple" as compatible string we
can define almost all properties of a DSI panel by a
device tree entry.

Except the connector and bus format which can only be
set by adding the same information to the panel-simple tables.

This leads to big problems because DRM can't match the
display with any lcd controller. The least issue is a
warning:

[    0.313431] panel-simple claa070vc01: Specify missing connector_type

Are we missing some documentation or code that reads
some "connector-type" and "bus-format" property?

BR and thanks,
Nikolaus
