374  * drm_dp_downstream_is_type() - is the downstream facing port of certain type?
384  * Returns: whether the downstream facing port matches the type.
396  * drm_dp_downstream_is_tmds() - is the downstream facing port TMDS?
401  * Returns: whether the downstream facing port is TMDS (HDMI/DVI).
578  * drm_dp_read_downstream_info() - read DPCD downstream port info if available
581  * @downstream_ports: buffer to store the downstream port info in
587  * Returns: 0 if either the downstream port info was read successfully or
588  * there was no downstream info to read, or a negative error code otherwise.
599 	/* No downstream info to read */  in drm_dp_read_downstream_info()
