2016-07-17[media] doc-rst: Fix conversion for v4l2 core functionsMauro Carvalho Chehab1-5/+8
The conversion from DocBook lead into some conversion issues, basically due to the lack of proper support at kernel-doc. So, address them: - Now, the C files with the exported symbols also need to be added. So, all headers need to be included twice: one to get the structs/enums/.. and another one for the functions; - Notes should use the ReST tag, as kernel-doc doesn't recognizes it anymore; - Identation needs to be fixed, as ReST uses it to identify when a format "tag" ends. - kernel-doc doesn't escape things like *pointer, so we need to manually add a escape char before it. - On some cases, kernel-doc conversion requires violating the 80-cols, as otherwise it won't properly parse the source code.

2016-03-03[media] v4l: Add generic pipeline power management codeSakari Ailus1-1/+42
When the Media controller framework was merged, it was decided not to add pipeline power management code for it was not seen generic. As a result, a number of drivers have copied the same piece of code, with same bugfixes done to them at different points of time (or not at all). Add these functions to V4L2. Their use is optional for drivers.

2016-02-27[media] media: v4l-core add enable/disable source common interfacesShuah Khan1-1/+64
Add a new interfaces to be used by v4l-core to invoke enable source and disable_source handlers in the media_device. The enable_source helper function invokes the enable_source handler to find media source entity connected to the entity and check is it is available or busy. If source is available, link is activated and pipeline is started. The disable_source helper function invokes the disable_source handler to deactivate and stop the pipeline.

2016-02-10[media] v4l2-mc: add a generic function to create the media graphMauro Carvalho Chehab1-0/+25
The em28xx_v4l2_create_media_graph() is almost generic enough to be at the core, as an ancillary function. Make it even more generic, by getting rid of em28xx-specific code, relying only at the media_device, in order to discover all entities found on PC-customer's hardware and add it at the V4L2 core.

2016-02-01[media] v4l2-mc.h: move tuner PAD definitions to this new headerMauro Carvalho Chehab1-0/+38
The customer PC hardware can be shipped with lots of different configurations, as vendors use to replace some of the chips on their hardware along the time. All drivers that support such devices are prepared to handle the hardware differences, using their own auto-probing logic. They do it in a way that number of inputs and outputs for a given hardware type doesn't change. Now that we're adding media controller capabilities to those drivers, we need to standardize the number of inputs and outputs for each hardware type, as we want to have a generic function at the V4L2 core that would create the links for the entities that are expected on such hardware. Such standard is already there for tuners, but tuner.h is not the best place to store such data, as we'll need to add definitions also for analog TV demodulators. Also, we'll need a place to put a set of MC handling functions. So, let's create a v4l2-mc.h to store such kind of definitions. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
