Subject: [PATCH 0/8] Add a panel API to return panel orientation
Date: Wed,  1 Jun 2022 16:18:15 +0800	[thread overview]
Message-ID: <20220601081823.1038797-1-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_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.
