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_connector_set_orientation_from_panel()
for drm/kms drivers. The drivers can call the API to set panel's
orientation before drm_dev_register().

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

hi Maintainers,

All the patches are reviewed. If there's no other comments, will this
series be picked? Thanks.

Unless someone beat me to it or yells, my plan was to land them to
drm-misc-next next week. Since it touches core code I wanted to give a
little extra time. Also at the moment patch #8 is all Chromium (all
author and reviewers are chromium.org) at the moment so that's another
reason to make sure it has sufficient time on the lists.

As promised, I've pushed to drm-misc-next. Note: I had to fix
whitespace problems in almost every patch. Please run checkpatch on
your patches.
