History: v4: - Removed the endpoint parsing callback APIs from video-mux and imx drivers as suggested by Sakari, replacing with endpoint parsing local to the drivers and the use of v4l2_async_notifier_add_fwnode_remote_subdev(). As a result convenience function v4l2_async_register_fwnode_subdev() is no longer used and is reverted. v3: - The changes to the default behaviour in media_entity_get_fwnode_pad(), and the fixes to current media drivers that call it inconsistently, have been put-off to another time. Instead this version implements the get_fwnode_pad operation where required in the imx and video-mux subdevices to make media link creation work correctly. The improvements to media_entity_get_fwnode_pad() can wait to another patch series. v2: - rename/move the notifier-to-state inlines in imx7-mipi-csis.c and imx7-media-csi.c, suggested by Rui Silva. - rewrite imx_media_create_links() to only add the missing media links from the imx6 MIPI CSI-2 receiver.
