This was required because there was no clean way to derive the platform device from the DSI module instance number or from the connected panel. With the new output entity, it is possible to retrieve the platform device pointer if the omap_dss_output pointer is available. Modify the functions dsi_get_dsidev_from_dssdev() dsi_get_dsidev_from_id() so that they use output instead of dsi_pdev_map to retrieve the dsi platform device pointer.
