* DRM connectors have a few standardized properties:
*
* EDID:
- * Blob property which contains the current EDID read from the sink. This
- * is useful to parse sink identification information like vendor, model
- * and serial. Drivers should update this property by calling
- * drm_connector_update_edid_property(), usually after having parsed
- * the EDID using drm_add_edid_modes(). Userspace cannot change this
- * property.
- *
- * User-space should not parse the EDID to obtain information exposed via
- * other KMS properties (because the kernel might apply limits, quirks or
- * fixups to the EDID). For instance, user-space should not try to parse
- * mode lists from the EDID.

* DPMS:
- * Legacy property for setting the power state of the connector. For atomic
- * drivers this is only provided for backwards compatibility with existing
- * drivers, it remaps to controlling the "ACTIVE" property on the CRTC the
- * connector is linked to. Drivers should never set this property directly,
- * it is handled by the DRM core by calling the &drm_connector_funcs.dpms
- * callback. For atomic drivers the remapping to the "ACTIVE" property is
- * implemented in the DRM core.
- *
- * Note that this property cannot be set through the MODE_ATOMIC ioctl,
- * userspace must use "ACTIVE" on the CRTC instead.
- *
- * WARNING:
- *
- * For userspace also running on legacy drivers the "DPMS" semantics are a
- * lot more complicated. First, userspace cannot rely on the "DPMS" value
- * returned by the GETCONNECTOR actually reflecting reality, because many
- * drivers fail to update it. For atomic drivers this is taken care of in
- * drm_atomic_helper_update_legacy_modeset_state().
- *
- * The second issue is that the DPMS state is only well-defined when the
- * connector is connected to a CRTC. In atomic the DRM core enforces that
- * "ACTIVE" is off in such a case, no such checks exists for "DPMS".
- *
- * Finally, when enabling an output using the legacy SETCONFIG ioctl then
- * "DPMS" is forced to ON. But see above, that might not be reflected in
- * the software value on legacy drivers.
- *
- * Summarizing: Only set "DPMS" when the connector is known to be enabled,
- * assume that a successful SETCONFIG call also sets "DPMS" to on, and
- * never read back the value of "DPMS" because it can be incorrect.

* PATH:
- * Connector path property to identify how this sink is physically

- * 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.

- * Connector tile group property to indicate how a set of DRM connector
