Re: [PATCH v7 8/8] drm: Config orientation property if panel provides it

Quoting Hsin-Yi Wang (2022-06-09 00:27:23)

Panel orientation property should be set before drm_dev_register(). Some drm driver calls drm_dev_register() in .bind(). However, most panels sets orientation property relatively late, mostly in .get_modes() callback, since this is when they are able to get the connector and binds the orientation property to it, though the value should be known when the panel is probed.

In drm_bridge_connector_init(), if a bridge is a panel bridge, use it to set the connector's panel orientation property.
