Actually, when a panel is attached the default panel's mode is used, but in some cases we can't get display up if mode getting from eDP control EDID is not chosen. This series address that problem, first implements the .get_edid() callback in the PS8640 driver (which is not used until the conversion is done) and then, converts the Mediatek DSI driver to use the drm_bridge API. As far as I know, we're the only users of the mediatek dsi driver in mainline, so should be safe to switch to the new chain of drm_bridge API unconditionally. The patches has been tested on a Acer Chromebook R13 (Elm) running a Chrome OS userspace and checking that the valid EDID mode reported by the bridge is selected.
