Subject: [PATCH v6 0/8] Add a panel API to set orientation properly
Date: Wed,  8 Jun 2022 17:48:08 +0800	[thread overview]
Message-ID: <20220608094816.2898692-1-hsinyi@chromium.org> (raw)

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.
