27 A pad is a connection endpoint through which an entity can interact with
28 other entities. Data (not restricted to video) produced by an entity
29 flows from the entity's output to one or more entity inputs. Pads should

60 instance, defined in ``include/media/media-entity.h``. The structure is usually
65 Drivers initialize entity pads by calling
78 ``include/media/media-entity.h``. Currently, only one type of interface is
90 defined in ``include/media/media-entity.h``. Each entity stores its pads in
91 a pads array managed by the entity driver. Drivers usually embed the array in
94 Pads are identified by their entity and their 0-based index in the pads
115 defined in ``include/media/media-entity.h``. There are two types of links:
119 Associate two entities via their PADs. Each entity has a list that points
121 A given link is thus stored twice, once in the source entity and once in
122 the target entity.
128 **2. interface to entity links**:
132 Drivers create interface to entity links by calling:
155     struct media_entity *entity;
157     media_device_for_each_entity(entity, mdev) {
158     // entity will point to each entity in turn
163 reached only through enabled links starting at a given entity. The media
177 traversal at the given entity.
