Remove the TODO items regarding media link creation, these issues are resolved after exporting media link creation to individual entity bound callbacks and the use of media_create_fwnode_links(), media_create_fwnode_pad_links(), and media_entity_get_fwnode_pad().

If a port owned by a device in the graph has endpoint nodes, the - port is treated as a media pad. - - This presents problems for devices that don't make this port = pad - assumption. Examples are SMIAPP compatible cameras which define only - a single output port node, but which define multiple pads owned - by multiple subdevices (pixel-array, binner, scaler). Or video - decoders (entity function MEDIA_ENT_F_ATV_DECODER), which also define - only a single output port node, but define multiple pads for video, - VBI, and audio out. - - A workaround at present is to set the port reg properties to - correspond to the media pad index that the port represents. A - possible long-term solution is to implement a subdev API that - maps a port id to a media pad index. - - 2. Every endpoint of a port owned by a device in the graph is treated - as a media link. - - Which means a port must not contain mixed-use endpoints, they - must all refer to media links between V4L2 subdevices. - - i.MX7: all of the above, since it uses the imx media core - i.MX7: use Frame Interval Monitor -- 2.17.1 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
