Laurent Pinchart d0e3440dab media: mc: Expand MUST_CONNECT flag to always require an enabled link
[ Upstream commit b3decc5ce7d778224d266423b542326ad469cb5f ]

The MEDIA_PAD_FL_MUST_CONNECT flag indicates that the pad requires an
enabled link to stream, but only if it has any link at all. This makes
little sense, as if a pad is part of a pipeline, there are very few use
cases for an active link to be mandatory only if links exist at all. A
review of in-tree drivers confirms they all need an enabled link for
pads marked with the MEDIA_PAD_FL_MUST_CONNECT flag.

Expand the scope of the flag by rejecting pads that have no links at
all. This requires modifying the pipeline build code to add those pads
to the pipeline.

Merge tag 'media/v6.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - new i2c drivers: ds90ub913, ds90ub953, ds90ub960, dw9719, ds90ub913

 - new Intel IVSC MEI drivers

 - some Mediatek platform drivers were moved to a common location

 - Intel atomisp2 driver is now working with the main ov2680 driver. Due
   to that, the atomisp2 ov2680 staging one was removed

 - the bttv driver was finally converted to videobuf2 framework. This
   was the last one upstream using videobuf version 1 core. We'll likely
   remove the old videobuf framework on 6.7

 - lots of improvements at atomisp driver: it now works with normal I2C
   sensors. Several compile-mode dependecies to select between ISP2400
   and ISP2401 are now solved in runtime

 - a new ipu-bridge logic was added to work with IVSC MEI drivers

 - venus driver gained better support for new VPU versions

 - the v4l core async framework has gained lots of improvements and
   cleanups

 - lots of other cleanups, improvements and driver fixes

Tomi Valkeinen f57fa29592 media: v4l2-subdev: Add new ioctl for client capabilities
Add new ioctls to set and get subdev client capabilities. Client in this
context means the userspace application which opens the subdev device
node. The client capabilities are stored in the file handle of the
opened subdev device node, and the client must set the capabilities for
each opened subdev.

For now we only add a single flag, V4L2_SUBDEV_CLIENT_CAP_STREAMS, which
indicates that the client is streams-aware.

The reason for needing such a flag is as follows:

Many structs passed via ioctls, e.g. struct v4l2_subdev_format, contain
reserved fields (usually a single array field). These reserved fields
can be used to extend the ioctl. The userspace is required to zero the
reserved fields.

We recently added a new 'stream' field to many of these structs, and the
space for the field was taken from these reserved arrays. The assumption
was that these new 'stream' fields are always initialized to zero if the
userspace does not use them. This was a mistake, as, as mentioned above,
the userspace is required to zero the _reserved_ fields. In other words,
there is no requirement to zero this new stream field, and if the
userspace doesn't use the field (which is the case for all userspace
applications at the moment), the field may contain random data.

This shows that the way the reserved fields are defined in v4l2 is, in
my opinion, somewhat broken, but there is nothing to do about that.

To fix this issue we need a way for the userspace to tell the kernel
that the userspace has indeed set the 'stream' field, and it's fine for
the kernel to access it. This is achieved with the new ioctl, which the
userspace should usually use right after opening the subdev device node.

Dorota Czaplejewicz 1fde66dc57 media: media api: Try to make enum usage clearer
This clarifies which side of the calls is responsible for doing what to
which parts of the struct. It also expands the terse description of the
access algorithm into more prose-like, active voice description, which
trades conciseness for ease of comprehension.

Fixed: typo "format" -> "frame size" in enum-frame-size
Added: no holes in the enumeration
Added: enumerations per what?
Added: who fills in what in calls
Changed: "given" -> "specified"

Dorota Czaplejewicz 5a26272f9c media: doc/media api: Try to make enum usage clearer
This clarifies which side of the calls is responsible for doing what to
which parts of the struct. This also explicitly states that repeating
values are disallowed. It also expands the terse description of the access
algorithm into more prose-like, active voice description, which trades
conciseness for ease of comprehension.

Added: mbus codes must not repeat
Added: no holes in the enumeration
Added: enumerations per what?
Added: who fills in what in calls
Changed: "zero" -> "0"
Changed: "given" -> "specified"

Still unclear how it works so didn't describe: "which". What is a "try
format" vs "active format"?

Merge tag 'media/v6.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - Removal of several VB1-only deprecated drivers: cpia2, fsl-viu, meye,
   stkwebcam, tm6000, vpfe_capture and zr364xx

 - saa7146 recovered from staging/deprecated. We opted to give ti a
   chance, and, instead of deprecating it, the intention is to write
   patches migrating it from VB1 to VB2.

 - av7110 returned from staging/deprecated/ to staging/ as we're not
   planning on dropping it any time soon

 - media controller API has gained experimental support for G_ROUTING
   and streams API. No drivers use it right now. We're planning to add
   one after -rc1, giving some time to experience the API and eventually
   have changes during the next development cycle

 - New sensor drivers: imx296, imx415, ov8858

 - Atomisp had lots of changes, specially on its sensor's interface,
   making atomisp sensor drivers closer to normal sensor drivers

 - media controller kAPI has gained some helpers to traverse pipelines

 - uvcvideo now better support power line control

 - lots of bug fixes, cleanups and driver improvements

Merge tag 'drm-next-2023-02-23' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
 "There are a bunch of changes all over in the usual places.

  Highlights:

   - habanalabs moves from misc to accel

   - first accel driver for Intel VPU (Versatile Processing Unit)
     inference engine

   - dropped all the ancient legacy DRI1 drivers. I think it's been at
     least 10 years since anyone has heard about these.

   - Intel DG2 updates and prelim Meteorlake enablement

   - etnaviv adds support for Versilicon NPU device (a GPU like engine
     with inference accelerators)

Hans Verkuil ba47652ba6 media: meye: remove this deprecated driver
The meye driver does not use the vb2 framework for streaming
video, instead it implements this in the driver. This is error prone,
and nobody stepped in to convert this driver to that framework.

The hardware is very old, so the decision was made to remove it
altogether.

Sakari Ailus 58388bd700 media: Documentation: Update documentation for streams
Document how streams interacts with formats and selections.

Update documentation in respect to what is allowed, in particular streams
are only supported via full routes, source-only routes are not supported
right now.

The centerpiece of the API additions are streams. Albeit routes are
configured via S_ROUTING IOCTL that also declares streams, it is streams
that are accessed through other APIs. Thus refer to streams instead of
routes in documentation.

Tomi Valkeinen 2f91e10ee6 media: subdev: add stream based configuration
Add support to manage configurations (format, crop, compose) per stream,
instead of per pad. This is accomplished with data structures that hold
an array of all subdev's stream configurations.

The number of streams can vary at runtime based on routing. Every time
the routing is changed, the stream configurations need to be
re-initialized.

Linus Torvalds a7cacfb068 This was a not-too-busy cycle for documentation; highlights include:
- The beginnings of a set of translations into Spanish, headed up by Carlos
   Bilbao.
 
 - More Chinese translations.
 
 - A change to the Sphinx "alabaster" theme by default for HTML generation.
   Unlike the previous default (Read the Docs), alabaster is shipped with
   Sphinx by default, reducing the number of other dependencies that need to
   be installed.  It also (IMO) produces a cleaner and more readable result.
 
 - The ability to render the documentation into the texinfo format
   (something Sphinx could always do, we just never wired it up until now).
 
 Plus the usual collection of typo fixes, build-warning fixes, and minor
 updates.
