media: uapi/linux/media.h: add request API

2018-08-31T15:04:23+00:00

Define the public request API.

This adds the new MEDIA_IOC_REQUEST_ALLOC ioctl to allocate a request
and two ioctls that operate on a request in order to queue the
contents of the request to the driver and to re-initialize the
request.

media: media.h: remove linux/version.h include

2018-07-27T11:52:39+00:00

The media.h public header is one of only three public headers that include
linux/version.h. Drop it from media.h. It was only used for an obsolete
define.

It has to be added to media-device.c, since that source relied on media.h
to include it.

media: media.h: reorder video en/decoder functions

2018-07-25T11:51:05+00:00

Keep the function defines in numerical order: 0x6000 comes after
0x2000, so move it back.

media: rename MEDIA_ENT_F_DTV_DECODER to MEDIA_ENT_F_DV_DECODER

2018-07-25T11:49:28+00:00

The use of 'DTV' is very confusing since it normally refers to Digital
TV e.g. DVB etc.

Instead use 'DV' (Digital Video), which nicely corresponds to the
DV Timings API used to configure such receivers and transmitters.

We keep an alias to avoid breaking userspace applications.

Since this alias is only available if __KERNEL__ is *not* defined
(i.e. it is only available for userspace, not kernelspace), any
drivers that use it also have to be converted to the new define.
These drivers are adv7604, adv7842 and tda1997x.

media: add flags field to struct media_v2_entity

2018-07-25T11:46:24+00:00

The v2 entity structure never exposed the entity flags, which made it
impossible to detect connector or default entities.

It is really trivial to just expose this information, so implement this.

media: add 'index' to struct media_v2_pad

2018-07-25T11:42:53+00:00

The v2 pad structure never exposed the pad index, which made it impossible
to call the MEDIA_IOC_SETUP_LINK ioctl, which needs that information.

It is really trivial to just expose this information, so implement this.

media: media.h: remove __NEED_MEDIA_LEGACY_API

2018-06-28T12:10:51+00:00

The __NEED_MEDIA_LEGACY_API define is 1) ugly and 2) dangerous
since it is all too easy for drivers to define it to get hold of
legacy defines. Instead just define what we need in media-device.c
which is the only place where we need the legacy define
(MEDIA_ENT_T_DEVNODE_UNKNOWN).

media: media.h: reorganize header to make it easier to understand

2018-02-26T15:14:46+00:00

The media.h public header is very messy. It mixes legacy and 'new' defines
and it is not easy to figure out what should and what shouldn't be used. It
also contains confusing comment that are either out of date or completely
uninteresting for anyone that needs to use this header.

The patch groups all entity functions together, including the 'old' defines
based on the old range base. The reader just wants to know about the available
functions and doesn't care about what range is used.

All legacy defines are moved to the end of the header, so it is easier to
locate them and just ignore them.

The legacy structs in the struct media_entity_desc are put under
also a much more effective signal to the reader that they shouldn't be used
compared to the old method of relying on '#if 1' followed by a comment.

The unused MEDIA_INTF_T_ALSA_* defines are also moved to the end of the header
in the legacy area. They are also dropped from intf_type() in media-entity.c.

All defines are also aligned at the same tab making the header easier to read.
