Physical the TVP5150 has three ports: AIP1A, AIP1B and YOUT. As result of discussion [1],[2] the device-tree maps these ports 1:1. The svideo connector must be conneted to port@0/endpoint@1, look at the Documentation for more information. Since the TVP5150 is a converter the device-tree must contain at least 1-input and 1-output port. The mc-connectors and mc-links are only created if the device-tree contains the corresponding connector nodes. If more than one connector is available the media_entity_operations.link_setup() callback ensures that only one connector is active.

So each driver have to add ifdefs around those helpers or add the CONFIG_VIDEO_V4L2_SUBDEV_API as dependcy. Make these helpers available in case of CONFIG_VIDEO_V4L2_SUBDEV_API isn't set to avoid ifdefs. This approach is less error prone too.

The TVP5150 AVID will be updated if the 'which' field is FORMAT_ACTIVE and the requested selection rectangle differs from the already set one.
