+ * Page flipping is a synchronization mechanism that replaces the frame

+ * vertical blanking, avoiding tearing (except when requested otherwise
+ * through the DRM_MODE_PAGE_FLIP_ASYNC flag). When an application
+ * requests a page flip the DRM core verifies that the new frame buffer
+ * is large enough to be scanned out by the CRTC in the currently
+ * configured mode and then calls the CRTC ->page_flip() operation with a
+ * pointer to the new frame buffer.
+ *
+ * The driver must wait for any pending rendering to the new framebuffer
+ * to complete before executing the flip. It should also wait for any
+ * pending rendering from other drivers if the underlying buffer is a
+ * shared dma-buf.
+ *
+ * An application can request to be notified when the page flip has
+ * completed. The drm core will supply a struct &drm_event in the event
+ * parameter in this case. This can be handled by the
+ * drm_crtc_send_vblank_event() function, which the driver should call on
+ * the provided event upon completion of the flip. Note that if
+ * the driver supports vblank signalling and timestamping the vblank
+ * counters and timestamps must agree with the ones returned from page
+ * flip events. With the current vblank helper infrastructure this can
+ * be achieved by holding a vblank reference while the page flip is
+ * pending, acquired through drm_crtc_vblank_get() and released with
+ * drm_crtc_vblank_put(). Drivers are free to implement their own vblank
+ * counter and timestamp tracking though, e.g. if they have accurate
+ * timestamp registers in hardware.
+ *
+ * FIXME:
+ *
+ * Up to that point drivers need to manage events themselves and can use

+ * This header provides constants for binding nvidia,tegra210-car.
+ *
+ * The first 224 clocks are numbered to match the bits in the CAR's CLK_OUT_ENB
+ * registers. These IDs often match those in the CAR's RST_DEVICES registers,
+ * but not in all cases. Some bits in CLK_OUT_ENB affect multiple clocks. In
+ * this case, those clocks are assigned IDs above 224 in order to highlight
+ * this issue. Implementations that interpret these clock IDs as bit values
+ * within the CLK_OUT_ENB or RST_DEVICES registers should be careful to
+ * explicitly handle these special cases.
+ *
+ * The balance of the clocks controlled by the CAR are assigned IDs of 224 and
+ * above.

+ * The checksum related features are:

+ * IP (one's complement) checksum for any combination
+ * of protocols or protocol layering. The checksum is
+ * computed and set in a packet per the CHECKSUM_PARTIAL
+ * interface (see below).
+ *
+ * NETIF_F_IP_CSUM - Driver (device) is only able to checksum plain
+ * TCP or UDP packets over IPv4. These are specifically
+ * unencapsulated packets of the form IPv4|TCP or
+ * IPv4|UDP where the Protocol field in the IPv4 header
+ * is TCP or UDP. The IPv4 header may contain IP options
+ * This feature cannot be set in features for a device
+ * with NETIF_F_HW_CSUM also set. This feature is being
+ * DEPRECATED (see below).
+ *
+ * NETIF_F_IPV6_CSUM - Driver (device) is only able to checksum plain
+ * TCP or UDP packets over IPv6. These are specifically
+ * unencapsulated packets of the form IPv6|TCP or
+ * IPv4|UDP where the Next Header field in the IPv6
+ * header is either TCP or UDP. IPv6 extension headers
+ * are not supported with this feature. This feature
+ * cannot be set in features for a device with
+ * NETIF_F_HW_CSUM also set. This feature is being
+ * DEPRECATED (see below).
+ *
+ * NETIF_F_RXCSUM - Driver (device) performs receive checksum offload.
+ * This flag is used only used to disable the RX checksum
+ * feature for a device. The stack will accept receive
+ * checksum indication in packets received on a device
+ * regardless of whether NETIF_F_RXCSUM is set.

+ * B. Checksumming of received packets by device. Indication of checksum
+ * verification is in set skb->ip_summed. Possible values are:
*
* CHECKSUM_NONE:
*
- * Device failed to checksum this packet e.g. due to lack of capabilities.

+ * C. Checksumming on transmit for non-GSO. The stack requests checksum offload
+ * in the skb->ip_summed for a packet. Values are:
*
* CHECKSUM_PARTIAL:

- * The device is required to checksum the packet as seen by hard_start_xmit()

+ * checksum refers to a legitimate transport layer checksum-- it is the
+ * purview of the stack to validate that csum_start and csum_offset are set
+ * correctly.
+ *
+ * When the stack requests checksum offload for a packet, the driver MUST
+ * ensure that the checksum is set correctly. A driver can either offload the
+ * checksum calculation to the device, or call skb_checksum_help (in the case
+ * that the device does not support offload for a particular checksum).
+ *
+ * NETIF_F_IP_CSUM and NETIF_F_IPV6_CSUM are being deprecated in favor of
+ * NETIF_F_HW_CSUM. New devices should use NETIF_F_HW_CSUM to indicate
+ * checksum offload capability. If a device has limited checksum capabilities
+ * (for instance can only perform NETIF_F_IP_CSUM or NETIF_F_IPV6_CSUM as
+ * described above) a helper function can be called to resolve
+ * CHECKSUM_PARTIAL. The helper functions are skb_csum_off_chk*. The helper
+ * function takes a spec argument that describes the protocol layer that is
+ * supported for checksum offload and can be called for each packet. If a
+ * packet does not match the specification for offload, skb_checksum_help
+ * is called to resolve the checksum.

- * IPv4. Sigh. Vendors like this way for an unknown reason.
- * Though, see comment above about CHECKSUM_UNNECESSARY. 8)
- * NETIF_F_IPV6_CSUM - About as dumb as the last one but does IPv6 instead.
- * NETIF_F_... - Well, you get the picture.
+ * The skb was already checksummed by the protocol, or a checksum is not
+ * required.
*
* CHECKSUM_UNNECESSARY:
*
- * Normally, the device will do per protocol specific checksumming. Protocol
- * implementations that do not want the NIC to perform the checksum
- * calculation should use this flag in their outgoing skbs.
- *
- * NETIF_F_FCOE_CRC - This indicates that the device can do FCoE FC CRC
- * offload. Correspondingly, the FCoE protocol driver
- * stack should use CHECKSUM_UNNECESSARY.
+ * This has the same meaning on as CHECKSUM_NONE for checksum offload on
+ * output.
*
- * Any questions? No questions, good. --ANK
+ * CHECKSUM_COMPLETE:
+ * Not used in checksum output. If a driver observes a packet with this value
+ * set in skbuff, if should treat as CHECKSUM_NONE being set.
+ *
+ * D. Non-IP checksum (CRC) offloads
+ *
+ * NETIF_F_SCTP_CRC - This feature indicates that a device is capable of
+ * offloading the SCTP CRC in a packet. To perform this offload the stack
+ * will set ip_summed to CHECKSUM_PARTIAL and set csum_start and csum_offset
+ * accordingly. Note the there is no indication in the skbuff that the
+ * CHECKSUM_PARTIAL refers to an SCTP checksum, a driver that supports
+ * both IP checksum offload and SCTP CRC offload must verify which offload
+ * is configured for a packet presumably by inspecting packet headers.
+ *
+ * NETIF_F_FCOE_CRC - This feature indicates that a device is capable of
+ * offloading the FCOE CRC in a packet. To perform this offload the stack
+ * will set ip_summed to CHECKSUM_PARTIAL and set csum_start and csum_offset
+ * accordingly. Note the there is no indication in the skbuff that the
+ * CHECKSUM_PARTIAL refers to an FCOE checksum, a driver that supports
+ * both IP checksum offload and FCOE CRC offload must verify which offload
+ * is configured for a packet presumably by inspecting packet headers.
+ *
+ * E. Checksumming on output with GSO.
+ *
+ * In the case of a GSO packet (skb_is_gso(skb) is true), checksum offload
+ * is implied by the SKB_GSO_* flags in gso_type. Most obviously, if the
+ * gso_type is SKB_GSO_TCPV4 or SKB_GSO_TCPV6, TCP checksum offload as
+ * part of the GSO operation is implied. If a checksum is being offloaded
+ * with GSO then ip_summed is CHECKSUM_PARTIAL, csum_start and csum_offset

+/**
+ * DOC: Media Controller
+ *
+ * The media controller userspace API is documented in DocBook format in
+ * Documentation/DocBook/media/v4l/media-controller.xml. This document focus
+ * on the kernel-side implementation of the media framework.
+ *
+ * * Abstract media device model:
+ *
+ * Discovering a device internal topology, and configuring it at runtime, is one
+ * of the goals of the media framework. To achieve this, hardware devices are
+ * modelled as an oriented graph of building blocks called entities connected
+ * through pads.
+ *
+ * An entity is a basic media hardware building block. It can correspond to
+ * a large variety of logical blocks such as physical hardware devices
+ * (CMOS sensor for instance), logical hardware devices (a building block
+ * in a System-on-Chip image processing pipeline), DMA channels or physical
+ * connectors.
+ *
+ * A pad is a connection endpoint through which an entity can interact with
+ * other entities. Data (not restricted to video) produced by an entity
+ * flows from the entity's output to one or more entity inputs. Pads should
+ * not be confused with physical pins at chip boundaries.
+ *
+ * A link is a point-to-point oriented connection between two pads, either
+ * on the same entity or on different entities. Data flows from a source
+ * pad to a sink pad.
+ *
+ *
+ * * Media device:
+ *
+ * A media device is represented by a struct &media_device instance, defined in
+ * include/media/media-device.h. Allocation of the structure is handled by the
+ * media device driver, usually by embedding the &media_device instance in a
+ * larger driver-specific structure.
+ *
+ * Drivers register media device instances by calling
+ * __media_device_register() via the macro media_device_register()
+ * and unregistered by calling
+ * media_device_unregister().
+ *
+ * * Entities, pads and links:
+ *
+ * - Entities
+ *
+ * Entities are represented by a struct &media_entity instance, defined in
+ * include/media/media-entity.h. The structure is usually embedded into a
+ * higher-level structure, such as a v4l2_subdev or video_device instance,
+ * although drivers can allocate entities directly.
+ *
+ * Drivers initialize entity pads by calling
+ * media_entity_pads_init().
+ *
+ * Drivers register entities with a media device by calling
+ * media_device_register_entity()
+ * and unregistred by calling
+ * media_device_unregister_entity().
+ *
+ * - Interfaces
+ *
+ * Interfaces are represented by a struct &media_interface instance, defined in
+ * include/media/media-entity.h. Currently, only one type of interface is
+ * defined: a device node. Such interfaces are represented by a struct
+ * &media_intf_devnode.
+ *
+ * Drivers initialize and create device node interfaces by calling
+ * media_devnode_create()
+ * and remove them by calling:
+ * media_devnode_remove().
+ *
+ * - Pads
+ *
+ * Pads are represented by a struct &media_pad instance, defined in
+ * include/media/media-entity.h. Each entity stores its pads in a pads array
+ * managed by the entity driver. Drivers usually embed the array in a
+ * driver-specific structure.
+ *
+ * Pads are identified by their entity and their 0-based index in the pads
+ * array.
+ * Both information are stored in the &media_pad structure, making the
+ * &media_pad pointer the canonical way to store and pass link references.
+ *
+ * Pads have flags that describe the pad capabilities and state.
+ *
+ * %MEDIA_PAD_FL_SINK indicates that the pad supports sinking data.
+ * %MEDIA_PAD_FL_SOURCE indicates that the pad supports sourcing data.
+ *
+ * NOTE: One and only one of %MEDIA_PAD_FL_SINK and %MEDIA_PAD_FL_SOURCE must
+ * be set for each pad.
+ *
+ * - Links
+ *
+ * Links are represented by a struct &media_link instance, defined in
+ * include/media/media-entity.h. There are two types of links:
+ *
+ * 1. pad to pad links:
+ *
+ * Associate two entities via their PADs. Each entity has a list that points
+ * to all links originating at or targeting any of its pads.
+ * A given link is thus stored twice, once in the source entity and once in
+ * the target entity.
+ *
+ * Drivers create pad to pad links by calling:
+ * media_create_pad_link() and remove with media_entity_remove_links().
+ *
+ * 2. interface to entity links:
+ *
+ * Associate one interface to a Link.
+ *
+ * Drivers create interface to entity links by calling:
+ * media_create_intf_link() and remove with media_remove_intf_links().
+ *
+ * NOTE:
+ *
+ * Links can only be created after having both ends already created.
+ *
+ * Links have flags that describe the link capabilities and state. The
+ * valid values are described at media_create_pad_link() and
+ * media_create_intf_link().
+ *
+ * Graph traversal:
+ *
+ * The media framework provides APIs to iterate over entities in a graph.
+ *
+ * To iterate over all entities belonging to a media device, drivers can use
+ * the media_device_for_each_entity macro, defined in
+ * include/media/media-device.h.
+ *
+ * struct media_entity *entity;
+ *
+ * media_device_for_each_entity(entity, mdev) {
+ * // entity will point to each entity in turn
+ * ...
+ * }
+ *
+ * Drivers might also need to iterate over all entities in a graph that can be
+ * reached only through enabled links starting at a given entity. The media
+ * framework provides a depth-first graph traversal API for that purpose.
+ *
+ * Note that graphs with cycles (whether directed or undirected) are *NOT*
+ * supported by the graph traversal API. To prevent infinite loops, the graph
+ * traversal code limits the maximum depth to MEDIA_ENTITY_ENUM_MAX_DEPTH,
+ * currently defined as 16.
+ *
+ * Drivers initiate a graph traversal by calling
+ * media_entity_graph_walk_start()
+ *
+ * The graph structure, provided by the caller, is initialized to start graph
+ * traversal at the given entity.
+ *
+ * Drivers can then retrieve the next entity by calling
+ * media_entity_graph_walk_next()
+ *
+ * When the graph traversal is complete the function will return NULL.
+ *
+ * Graph traversal can be interrupted at any moment. No cleanup function call
+ * is required and the graph structure can be freed normally.
+ *
+ * Helper functions can be used to find a link between two given pads, or a pad
+ * connected to another pad through an enabled link
+ * media_entity_find_link() and media_entity_remote_pad()
+ *
+ * Use count and power handling:
+ *
+ * Due to the wide differences between drivers regarding power management
+ * needs, the media controller does not implement power management. However,
+ * the &media_entity structure includes a use_count field that media drivers
+ * can use to track the number of users of every entity for power management
+ * needs.
+ *
+ * The &media_entity.@use_count field is owned by media drivers and must not be
+ * touched by entity drivers. Access to the field must be protected by the
+ * &media_device.@graph_mutex lock.
+ *
+ * Links setup:
+ *
+ * Link properties can be modified at runtime by calling
+ * media_entity_setup_link()
+ *
+ * Pipelines and media streams:
+ *
+ * When starting streaming, drivers must notify all entities in the pipeline to
+ * prevent link states from being modified during streaming by calling
+ * media_entity_pipeline_start().
+ *
+ * The function will mark all entities connected to the given entity through
+ * enabled links, either directly or indirectly, as streaming.
+ *
+ * The &media_pipeline instance pointed to by the pipe argument will be stored
+ * in every entity in the pipeline. Drivers should embed the &media_pipeline
+ * structure in higher-level pipeline structures and can then access the
+ * pipeline through the &media_entity pipe field.

+ * must be identical for all nested calls to the function.
+ *
+ * media_entity_pipeline_start() may return an error. In that case, it will
+ * clean up any of the changes it did by itself.
+ *
+ * When stopping the stream, drivers must notify the entities with
+ * media_entity_pipeline_stop().
+ *
+ * If multiple calls to media_entity_pipeline_start() have been made the same
+ * number of media_entity_pipeline_stop() calls are required to stop streaming.
+ * The &media_entity pipe field is reset to NULL on the last nested stop call.
+ *
+ * Link configuration will fail with -%EBUSY by default if either end of the
+ * link is a streaming entity. Links that can be modified while streaming must
+ * be marked with the %MEDIA_LNK_FL_DYNAMIC flag.
+ *
+ * If other operations need to be disallowed on streaming entities (such as
+ * changing entities configuration parameters) drivers can explicitly check the
+ * media_entity stream_count field to find out if an entity is streaming. This
+ * operation must be done with the media_device graph_mutex held.
+ *
+ * Link validation:
+ *
+ * Link validation is performed by media_entity_pipeline_start() for any
+ * entity which has sink pads in the pipeline. The
+ * &media_entity.@link_validate() callback is used for that purpose. In
+ * @link_validate() callback, entity driver should check that the properties of
+ * the source pad of the connected entity and its own sink pad match. It is up
+ * to the type of the entity (and in the end, the properties of the hardware)
+ * what matching actually means.
+ *
+ * Subsystems should facilitate link validation by providing subsystem specific
+ * helper functions to provide easy access for commonly needed information, and
+ * in the end provide a way to use driver-specific callbacks.
