[PATCH v6 RESEND 1/3] gpu: drm: separate panel orientation property creating and value setting
drm_dev_register() sets connector->registration_state to DRM_CONNECTOR_REGISTERED and dev->registered to true. If drm_connector_set_panel_orientation() is first called after drm_dev_register(), it will fail several checks and results in following warning.
Add a function to create panel orientation property and set default value to UNKNOWN, so drivers can call this function to init the property earlier , and let the panel set the real value later.
