Merge tag 'media/v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull missed media updates from Mauro Carvalho Chehab:
 "It seems I screwed-up my previous pull request: it ends up that only
  half of the media patches that were in linux-next got merged in -rc1.

  The script which creates the signed tags silently failed due to
  5.19->6.0 so it ended generating a tag with incomplete stuff.

  So here are the missing parts:

   - a DVB core security fix

   - lots of fixes and cleanups for atomisp staging driver

   - old drivers that are VB1 are being moved to staging to be
     deprecated

   - several driver updates - mostly for embedded systems, but there are
     also some things addressing issues with some PC webcams, in the UVC
     video driver"

@ -214,18 +214,29 @@ Link properties can be modified at runtime by calling
Pipelines and media streams
^^^^^^^^^^^^^^^^^^^^^^^^^^^
A media stream is a stream of pixels or metadata originating from one or more
source devices (such as a sensors) and flowing through media entity pads
towards the final sinks. The stream can be modified on the route by the
devices (e.g. scaling or pixel format conversions), or it can be split into
multiple branches, or multiple branches can be merged.
A media pipeline is a set of media streams which are interdependent. This
interdependency can be caused by the hardware (e.g. configuration of a second
stream cannot be changed if the first stream has been enabled) or by the driver
due to the software design. Most commonly a media pipeline consists of a single
stream which does not branch.
When starting streaming, drivers must notify all entities in the pipeline to
prevent link states from being modified during streaming by calling
:c:func:`media_pipeline_start()`.
The function will mark all entities connected to the given entity through
enabled links, either directly or indirectly, as streaming.
The function will mark all the pads which are part of the pipeline as streaming.
The struct media_pipeline instance pointed to by
the pipe argument will be stored in every entity in the pipeline.
the pipe argument will be stored in every pad in the pipeline.
Drivers should embed the struct media_pipeline
in higher-level pipeline structures and can then access the
pipeline through the struct media_entity
pipeline through the struct media_pad
pipe field.
Calls to :c:func:`media_pipeline_start()` can be nested.

@ -28,3 +28,22 @@ Since getting a picture requires multiple processing steps,
this means that unlike in fixed pipelines the soft pipelines
on the ISP can do multiple processing steps in a single pipeline
element (in a single binary).
###
The sensor drivers use of v4l2_get_subdev_hostdata(), which returns
a camera_mipi_info struct. This struct is allocated/managed by
the core atomisp code. The most important parts of the struct
are filled by the atomisp core itself, like e.g. the port number.
The sensor drivers on a set_fmt call do fill in camera_mipi_info.data
which is a atomisp_sensor_mode_data struct. This gets filled from
a function called <sensor_name>_get_intg_factor(). This struct is not
used by the atomisp code at all. It is returned to userspace by
a ATOMISP_IOC_G_SENSOR_MODE_DATA and the Android userspace does use this.
Other members of camera_mipi_info which are set by some drivers are:
-metadata_width, metadata_height, metadata_effective_width, set by
the ov5693 driver (and used by the atomisp core)
-raw_bayer_order, adjusted by the ov2680 driver when flipping since
flipping can change the bayer order
