Subject: [PATCH v7 0/8] Add a panel API to set orientation properly
Date: Thu, 9 Jun 2022 15:27:14 +0800 [thread overview]
Message-ID: <20220609072722.3488207-1-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.
