Documentation

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.
