      "message": "[media] media: Entities, pads and links\n\nAs video hardware pipelines become increasingly complex and\nconfigurable, the current hardware description through v4l2 subdevices\nreaches its limits. In addition to enumerating and configuring\nsubdevices, video camera drivers need a way to discover and modify at\nruntime how those subdevices are connected. This is done through new\nelements called entities, pads and links.\n\nAn entity is a basic media hardware building block. It can correspond to\na large variety of logical blocks such as physical hardware devices\n(CMOS sensor for instance), logical hardware devices (a building block\nin a System-on-Chip image processing pipeline), DMA channels or physical\nconnectors.\n\nA pad is a connection endpoint through which an entity can interact with\nother entities. Data (not restricted to video) produced by an entity\nflows from the entity\u0027s output to one or more entity inputs. Pads should\nnot be confused with physical pins at chip boundaries.\n\nA link is a point-to-point oriented connection between two pads, either\non the same entity or on different entities. Data flows from a source\npad to a sink pad.\n\nLinks are stored in the source entity. To make backwards graph walk\nfaster, a copy of all links is also stored in the sink entity. The copy\nis known as a backlink and is only used to help graph traversal.\n\nThe entity API is made of three functions:\n\n- media_entity_init() initializes an entity. The caller must provide an\narray of pads as well as an estimated number of links. The links array\nis allocated dynamically and will be reallocated if it grows beyond the\ninitial estimate.\n\n- media_entity_cleanup() frees resources allocated for an entity. It\nmust be called during the cleanup phase after unregistering the entity\nand before freeing it.\n\n- media_entity_create_link() creates a link between two entities. An\nentry in the link array of each entity is allocated and stores pointers\nto source and sink pads.\n\nWhen a media device is unregistered, all its entities are unregistered\nautomatically.\n\nThe code is based on Hans Verkuil \u003chverkuil@xs4all.nl\u003e initial work.\n\nSigned-off-by: Laurent Pinchart \u003claurent.pinchart@ideasonboard.com\u003e\nSigned-off-by: Sakari Ailus \u003csakari.ailus@iki.fi\u003e\nAcked-by: Hans Verkuil \u003chverkuil@xs4all.nl\u003e\nSigned-off-by: Mauro Carvalho Chehab \u003cmchehab@redhat.com\u003e\n"
