* [media] v4l: v4l2_subdev userspace frame interval APILaurent Pinchart2011-03-22
| | | | | | | | | | | | | | | The three new ioctl VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL, VIDIOC_SUBDEV_G_FRAME_INTERVAL and VIDIOC_SUBDEV_S_FRAME_INTERVAL can be used to enumerate and configure a subdev's frame rate from userspace. Two new video::g/s_frame_interval subdev operations are introduced to support those ioctls. The existing video::g/s_parm operations are deprecated and shouldn't be used anymore.

* [media] v4l: v4l2_subdev userspace format APILaurent Pinchart2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a userspace API to get, set and enumerate the media format on a subdev pad. The format at the output of a subdev usually depends on the format at its input(s). The try format operation is thus not suitable for probing format at individual pads, as it can't modify the device state and thus can't remember the format tried at the input to compute the output format. To fix the problem, pass an extra argument to the get/set format operations to select the 'try' or 'active' format. The try format is used when probing the subdev. Setting the try format must not change the device configuration but can store data for later reuse. Data storage is provided at the file-handle level so applications probing the subdev concurently won't interfere with each other. The active format is used when configuring the subdev. It's identical to the format handled by the usual get/set operations.

* [media] v4l: Group media bus pixel codes by types and sort them alphabeticallyLaurent Pinchart2011-03-22
| | | | | | | | | | | | | | | Adding new pixel codes at the end of the enumeration will soon create a mess, so group the pixel codes by type and sort them by bus_width, bits per component, samples per pixel and order of subsamples. As the codes are part of the kernel ABI their value can't change when a new code is inserted in the enumeration, so they are given an explicit numerical value. When inserting a new pixel code developers must use and update the next free value.

* [media] v4l: Add a media_device pointer to the v4l2_device structureLaurent Pinchart2011-03-22
| | | | | | | | | | | | | | | | | The pointer will later be used to register/unregister media entities when registering/unregistering a v4l2_subdev or a video_device. With the introduction of media devices, device drivers need to store a pointer to a driver-specific structure in the device's drvdata. v4l2_device can't claim ownership of the drvdata anymore. To maintain compatibility with drivers that rely on v4l2_device storing a pointer to itself in the device's drvdata, v4l2_device_register() will keep doing so if the drvdata is NULL.

* [media] media: Pipelines and media streamsLaurent Pinchart2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | Drivers often need to associate pipeline objects to entities, and to take stream state into account when configuring entities and links. The pipeline API helps drivers manage that information. When starting streaming, drivers call media_entity_pipeline_start(). The function marks all entities connected to the given entity through enabled links, either directly or indirectly, as streaming. Similarly, when stopping the stream, drivers call media_entity_pipeline_stop(). The media_entity_pipeline_start() function takes a pointer to a media pipeline and stores it in every entity in the graph. Drivers should embed the media_pipeline structure in higher-level pipeline structures and can then access the pipeline through the media_entity structure. Link configuration will fail with -EBUSY by default if either end of the link is a streaming entity, unless the link is marked with the MEDIA_LNK_FL_DYNAMIC flag.

* [media] media: Entities, pads and linksLaurent Pinchart2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As video hardware pipelines become increasingly complex and configurable, the current hardware description through v4l2 subdevices reaches its limits. In addition to enumerating and configuring subdevices, video camera drivers need a way to discover and modify at runtime how those subdevices are connected. This is done through new elements called entities, pads and links. 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. Links are stored in the source entity. To make backwards graph walk faster, a copy of all links is also stored in the sink entity. The copy is known as a backlink and is only used to help graph traversal. The entity API is made of three functions: - media_entity_init() initializes an entity. The caller must provide an array of pads as well as an estimated number of links. The links array is allocated dynamically and will be reallocated if it grows beyond the initial estimate. - media_entity_cleanup() frees resources allocated for an entity. It must be called during the cleanup phase after unregistering the entity and before freeing it. - media_entity_create_link() creates a link between two entities. An entry in the link array of each entity is allocated and stores pointers to source and sink pads. When a media device is unregistered, all its entities are unregistered automatically. The code is based on Hans Verkuil <hverkuil@xs4all.nl> initial work.

The two child drivers are drivers/media/radio/radio-wl1273.c and sound/soc/codecs/wl1273.c. The radio-wl1273 driver implements the V4L2 interface and communicates with the device. The ALSA codec offers digital audio, without it only analog audio is available. Signed-off-by: Matti J.
