Physical the TVP5150 has three ports: AIP1A, AIP1B and YOUT. As result of discussion [1],[2] the device-tree maps these ports 1:1. Look at the Documentation for more information. Since the TVP5150 is a converter/bridge 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.

This leads into to complex deps for futher development. - tvp5150_dt_cleanup: enable function only if CONFIG_OF is enabled - tvp5150_parse_dt: enable function only if CONFIG_OF is enabled - tvp5150_probe: call tvp5150_dt_cleanup only if CONFIG_OF is enabled - Simplify link_setup routine: - use generic connector parsing since both series [1,2] are squashed into one - struct tvp5150: drop pads_state and modify_second_link property due to link_setup() rework. - tvp5150_link_setup: add more comments - tvp5150_link_setup: simply the link setup routine a lot. Edit the 2nd link directly within the driver instead of a recursive media-framework call (__media_entity_setup_link). This improves the readability and shrinks the driver code. - tvp5150_link_setup: disable all active links in case user switches connectors without disable it first. - tvp5150_registered: simplify default link enable path due to link_setup() rework. - General cleanups - tvp5150_parse_dt: drop unecessary test - tvp5150_parse_dt: add err message due to misconfiguration - tvp5150_parse_dt: make use of V4L2_MBUS_UNKNOWN definition - s/dev_dbg/dev_dbg_lvl v4: - rebase on top of media_tree/master, fix merge conflict due to commit 60359a28d592 ("media: v4l: fwnode: Initialise the V4L2 fwnode endpoints to zero") v3: - probe(): s/err/err_free_v4l2_ctrls - drop MC dependency for tvp5150_pads v2: - adapt commit message - unify ifdef switches - rename tvp5150_valid_input -> tvp5150_of_valid_input, to be more precise - mc: use 2-input and 1-output pad - mc: link svideo connector to both input pads - mc: enable/disable svideo links in one go - mc: change link_setup() behaviour, switch the input src don't require a explicite disable before. - mc: rename 'local' media_pad param to tvp5150_pad to avoid confusion - mc: enable link to the first available connector and set the corresponding tvp5150 input src per default during registered() - mc/of: factor out oftree connector allocation - of: drop svideo dt port - of: move svideo connector to port@0/endpoint@1 - of: require at least 1-in and 1-out endpoint squash!
