* | [media] media: add functions to allow creating interfacesMauro Carvalho Chehab2016-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Interfaces are different than entities: they represent a Kernel<->userspace interaction, while entities represent a piece of hardware/firmware/software that executes a function. Let's distinguish them by creating a separate structure to store the interfaces. Later patches should change the existing drivers and logic to split the current interface embedded inside the entity structure (device nodes) into a separate object of the graph.

* | [media] media: remove media entity .parent fieldJavier Martinez Canillas2016-01-11
| | | | | | | | | | | | | | | | | | | | Now that the struct media_entity .parent field is unused, it can be safely removed. Since all the previous users were converted to use the .mdev field from the embedded struct media_gobj instead.

* | [media] media: rename the function that create pad linksMauro Carvalho Chehab2016-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the new API, a link can be either between two PADs or between an interface and an entity. So, we need to use a better name for the function that create links between two pads. So, rename the such function to media_create_pad_link(). No functional changes. This patch was created via this shell script: for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f) $(find include/ -name '*.h' -type f) ; do sed s,media_entity_create_link,media_create_pad_link,g <$i >a && mv a $i; done Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Tested-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* | [media] media: use media_gobj inside linksMauro Carvalho Chehab2016-01-11
| | | | | | | | | | | | | | | | | | | | | | | | Just like entities and pads, links also need to have unique Object IDs along a given media controller.

* | [media] media: use media_gobj inside padsMauro Carvalho Chehab2016-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PADs also need unique object IDs that won't conflict with the entity object IDs. The pad objects are currently created via media_entity_init() and, once created, never change. While this will likely change in the future in order to support dynamic changes, for now we'll keep PADs as arrays and initialize the media_gobj embedded structs when registering the entity.

* | [media] media: get rid of unused "extra_links" param on media_entity_init()Mauro Carvalho Chehab2016-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, media_entity_init() creates an array with the links, allocated at init time. It provides a parameter (extra_links) that would allocate more links than the current needs, but this is not used by any driver. As we want to be able to do dynamic link allocation/removal, we'll need to change the implementation of the links. So, before doing that, let's first remove that extra unused parameter, in order to cleanup the interface first.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new media controller API to allocate media device as a device resource. When a media device is created on the main struct device which is the parent device for the interface device, it will be available to all drivers associated with that interface. For example, if a usb media device driver creates the media device on the main struct device which is common for all the drivers that control the media device, including the non-media ALSA driver, media controller API can be used to share access to the resources on the media device. This new interface provides the above described feature. A second interface that finds and returns the media device is added to allow drivers to find the media device created by any of the drivers associated with the device.

* | [media] videobuf2-core: fix plane_sizes handling in VIDIOC_CREATE_BUFSHans Verkuil2015-12-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The handling of q->plane_sizes was wrong in vb2_core_create_bufs(). The q->plane_sizes array was global and it was overwritten by create_bufs. So if reqbufs was called with e.g. size 100000 then q->plane_sizes[0] would be set to 100000. If create_bufs was called afterwards with size 200000, then q->plane_sizes[0] would be overwritten with the new value. Calling create_bufs again for size 100000 would cause an error since 100000 is now less than q->plane_sizes[0]. This patch fixes this problem by 1) removing q->plane_sizes and using the vb->planes[].length field instead, and 2) by introducing a min_length field in struct vb2_plane. This field is set to the plane size as returned by the queue_setup op and is the minimum required plane size. So user pointers or dmabufs should all be at least this size.

* | [media] vb2: drop v4l2_format argument from queue_setupHans Verkuil2015-12-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

Also, no fields after "private:" should be documented. As we don't want to strip the documentation, let's untag. This way, it will be seen only at the file, and not at the DocBooks.
