[Intel-gfx] [PATCH v2 15/15] drm/todo: add entry for converting the subsystem to struct drm_edid

[Jani Nikula]

We need to stop duplicating EDID validation and parsing all over the
subsystem in various broken ways.

v2: Update to reflect drm_connector_helper_get_modes()

+Convert core and drivers from struct edid to struct drm_edid
+------------------------------------------------------------
+
+Go through all drivers and drm core KMS code to convert all raw struct edid
+usage to the opaque struct drm_edid. See commit e4ccf9a777d3 ("drm/edid: add
+struct drm_edid container") for rationale.
+
+Convert drm_get_edid() and drm_do_get_edid() usage to drm_edid_read(),
+drm_edid_read_ddc(), or drm_edid_read_custom().
+
+Convert drm_add_edid_modes() and drm_connector_update_edid_property() to
+drm_edid_connector_update(). See drm_connector_helper_get_modes() for reference
+for converting the ->get_modes() hooks.
+
+Convert decentralized, direct struct edid parsing to centralized parsing in
+drm_edid.c. Prefer one-time parsing as part of drm_edid_connector_update() and
+storing the result in drm_connector->display_info over adding individual,
+exported parser functions.
+
+During the transition period, it may be necessary to use drm_edid_raw(), but do
+use it sparingly. Eventually, all of them need to go.
