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.

Vaio Picturebook Motion Eye Camera Driver
=========================================

This driver enable the use of video4linux compatible applications with the
Motion Eye camera. This driver requires the "Sony Laptop Extras" driver (which
can be found in the "Misc devices" section of the kernel configuration utility)
to be compiled and installed (using its "camera=1" parameter).
It can do at maximum 30 fps @ 320x240 or 15 fps @ 640x480.
Grabbing is supported in packed YUV colorspace only.
MJPEG hardware grabbing is supported via a private API (see below).
Hardware supported
------------------
This driver supports the 'second' version of the MotionEye camera :)
The first version was connected directly on the video bus of the Neomagic
video card and is unsupported.
The second one, made by Kawasaki Steel is fully supported by this
driver (PCI vendor/device is 0x136b/0xff01)
The third one, present in recent (more or less last year) Picturebooks
(C1M* models), is not supported. The manufacturer has given the specs
to the developers under a NDA (which allows the development of a GPL
driver however), but things are not moving very fast (see
http://r-engine.sourceforge.net/) (PCI vendor/device is 0x10cf/0x2011).
There is a forth model connected on the USB bus in TR1* Vaio laptops.
This camera is not supported at all by the current driver, in fact
little information if any is available for this camera
(USB vendor/device is 0x054c/0x0107).
Driver options
--------------
Several options can be passed to the meye driver using the standard
module argument syntax (<param>=<value> when passing the option to the
module or meye.<param>=<value> on the kernel boot line when meye is
statically linked into the kernel). Those options are:
.. code-block:: none
gbuffers: number of capture buffers, default is 2 (32 max)
gbufsize: size of each capture buffer, default is 614400
video_nr: video device to register (0 = /dev/video0, etc)
Module use
----------
In order to automatically load the meye module on use, you can put those lines
in your /etc/modprobe.d/meye.conf file:
.. code-block:: none
alias char-major-81 videodev
alias char-major-81-0 meye
options meye gbuffers=32
Usage:
------
.. code-block:: none
xawtv >= 3.49 (<http://bytesex.org/xawtv/>)
for display and uncompressed video capture:
xawtv -c /dev/video0 -geometry 640x480
or
xawtv -c /dev/video0 -geometry 320x240
motioneye (<http://popies.net/meye/>)
for getting ppm or jpg snapshots, mjpeg video
Bugs / Todo
-----------
- 'motioneye' still uses the meye private v4l1 API extensions.

Private API
-----------
The driver supports frame grabbing with the video4linux API,
so all video4linux tools (like xawtv) should work with this driver.
Besides the video4linux interface, the driver has a private interface
for accessing the Motion Eye extended parameters (camera sharpness,
agc, video framerate), the snapshot and the MJPEG capture facilities.
This interface consists of several ioctls (prototypes and structures
can be found in include/linux/meye.h):
MEYEIOC_G_PARAMS and MEYEIOC_S_PARAMS
Get and set the extended parameters of the motion eye camera.
The user should always query the current parameters with
MEYEIOC_G_PARAMS, change what he likes and then issue the
MEYEIOC_S_PARAMS call (checking for -EINVAL). The extended
parameters are described by the meye_params structure.
MEYEIOC_QBUF_CAPT
Queue a buffer for capture (the buffers must have been
obtained with a VIDIOCGMBUF call and mmap'ed by the
application). The argument to MEYEIOC_QBUF_CAPT is the
buffer number to queue (or -1 to end capture). The first
call to MEYEIOC_QBUF_CAPT starts the streaming capture.
MEYEIOC_SYNC
Takes as an argument the buffer number you want to sync.
This ioctl blocks until the buffer is filled and ready
for the application to use. It returns the buffer size.
MEYEIOC_STILLCAPT and MEYEIOC_STILLJCAPT
Takes a snapshot in an uncompressed or compressed jpeg format.
This ioctl blocks until the snapshot is done and returns (for
jpeg snapshot) the size of the image. The image data is
available from the first mmap'ed buffer.
Look at the 'motioneye' application code for an actual example.

This is the video4linux driver for the Motion Eye camera found
in the Vaio Picturebook laptops. Please read the material in
<file:Documentation/admin-guide/media/meye.rst> for more information.
If you say Y or M here, you need to say Y or M to "Sony Laptop
Extras" in the misc device section.
This driver is deprecated and is scheduled for removal by
the beginning of 2023. See the TODO file for more information.
To compile this driver as a module, choose M here: the
module will be called meye.
# SPDX-License-Identifier: GPL-2.0-only
obj-$(CONFIG_VIDEO_MEYE) += meye.o
The meye driver does not use the vb2 framework for streaming
video, instead it implements this in the driver.
To prevent removal of this driver early 2023 it has to be
converted to use vb2. Contact the linux-media@vger.kernel.org
mailing list if you want to do this.
