Subject[PATCH v4 0/8] Add a panel API to return panel orientation
Date
Panels usually call drm_connector_set_panel_orientation(), which is
later than drm/kms driver calling drm_dev_register(). This leads to a
WARN()[1].

The orientation property is known earlier. For example, some panels
parse the property through device tree during probe.

The series add a panel API drm_panel_get_orientation() for drm/kms
drivers. The drivers can use the API to get panel's orientation, so they
can call drm_connector_set_panel_orientation() before drm_dev_register().

Panel needs to implement .get_orientation callback to return the property.
