Documentation

Connector path property to identify how this sink is physically
connected. Used by DP MST. This should be set by calling
drm_connector_set_path_property(), in the case of DP MST with the
path property the MST manager created. Userspace cannot change this
property.

In the case of DP MST, the property has the format
``mst:<parent>-<ports>`` where ``<parent>`` is the KMS object ID of the
parent connector and ``<ports>`` is a hyphen-separated list of DP MST
port numbers. Note, KMS object IDs are not guaranteed to be stable
across reboots.
