If no pads are needed, drivers could either directly fill :c:type:`media_entity->num_pads ` with 0 and :c:type:`media_entity->pads ` with ``NULL`` or call this function that will do the same. As the number of pads is known in advance, the pads array is not allocated dynamically but is managed by the entity driver. Most drivers will embed the pads array in a driver-specific structure, avoiding dynamic allocation. Drivers must set the direction of every pad in the pads array before calling media_entity_pads_init().

Used only if **sink** is NULL. ``struct media_entity *sink`` pointer to :c:type:`media_entity` of the sink pad. If NULL, it will use all entities that matches the **sink_function**. ``const u16 sink_pad`` number of the sink pad in the pads array. ``u32 flags`` Link flags, as defined in include/uapi/linux/media.h. ``const bool allow_both_undefined`` if ``true``, then both **source** and **sink** can be NULL. In such case, it will create a crossbar between all entities that matches **source_function** to all entities that matches **sink_function**. If ``false``, it will return 0 and won't create any link if both **source** and **sink** are NULL. **Description** Valid values for flags: A ``MEDIA_LNK_FL_ENABLED`` flag indicates that the link is enabled and can be used to transfer media data. If multiple links are created and this flag is passed as an argument, only the first created link will have this flag. A ``MEDIA_LNK_FL_IMMUTABLE`` flag indicates that the link enabled state can't be modified at runtime. If ``MEDIA_LNK_FL_IMMUTABLE`` is set, then ``MEDIA_LNK_FL_ENABLED`` must also be set since an immutable link is always enabled. It is common for some devices to have multiple source and/or sink entities of the same type that should be linked. While media_create_pad_link() creates link by link, this function is meant to allow 1:n, n:1 and even cross-bar (n:n) links. .. note:: Before calling this function, media_entity_pads_init() and media_device_register_entity() should be called previously for the entities to be linked.h](h)}(h**Parameters**h]j')}(hjh]h Parameters}(hjhhhNhNubah}(h]h ]h"]h$]h&]uh1j&hjubah}(h]h ]h"]h$]h&]uh1hhf/var/lib/git/docbuild/linux/Documentation/driver-api/media/mc-core:337: ./include/media/media-entity.hhMhjubj )}(hhh](j )}(hY``const struct media_device *mdev`` Pointer to the media_device that contains the object h](j )}(h#``const struct media_device *mdev``h]j)}(hjۣh]hconst struct media_device *mdev}(hjݣhhhNhNubah}(h]h ]h"]h$]h&]uh1jhj٣ubah}(h]h ]h"]h$]h&]uh1j hf/var/lib/git/docbuild/linux/Documentation/driver-api/media/mc-core:337: ./include/media/media-entity.hhMhjգubj)}(hhh]h)}(h4Pointer to the media_device that contains the objecth]h4Pointer to the media_device that contains the object}(hjhhhNhNubah}(h]h ]h"]h$]h&]uh1hhjhMhjubah}(h]h ]h"]h$]h&]uh1j hjգubeh}(h]h ]h"]h$]h&]uh1j hjhMhjңubj )}(h```const u32 source_function`` Function of the source entities.
