760  * drm_dp_downstream_is_type() - is the downstream facing port of certain type?
770  * Returns: whether the downstream facing port matches the type.
782  * drm_dp_downstream_is_tmds() - is the downstream facing port TMDS?
787  * Returns: whether the downstream facing port is TMDS (HDMI/DVI).
962  * drm_dp_read_downstream_info() - read DPCD downstream port info if available
965  * @downstream_ports: buffer to store the downstream port info in
971  * Returns: 0 if either the downstream port info was read successfully or
972  * there was no downstream info to read, or a negative error code otherwise.
