The soc_camera driver (and soc_camera.h header) is obsolete and depends
on BROKEN. It's time to remove this driver and the last references to it.
The first two patches remove a SoC Camera reference in two media drivers.
These references are obsolete (these drivers no longer use soc_camera),
so update the MODULE_DESCRIPTION.
The next three patches remove soc_camera depencies in three board files.
This has been compile tested. Note that the camera support for those
boards has been dead for a long time, so this really removes it. These
three patches are independent of the other patches in this series.
Then the soc_camera driver itself is removed (including soc_camera
dependent sensor drivers). This patch is also independent of the
other patches.
The final patch removes the soc_camera.h header, and that requires
that patches 3-6 are all merged.
Regards,
Hans

The soc_camera.h header driver is about to be removed, so drop camera
support from this board. Note that the soc_camera driver itself has
long since been deprecated and can't be compiled anymore (it depends
on BROKEN), so camera support on this board has been broken for a long
time (at least since 4.6 when the mx2_camera.c was removed from soc_camera).

The soc_camera driver is about to be removed, so drop camera
support from this board. Note that the soc_camera driver itself has
long since been deprecated and can't be compiled anymore (it depends
on BROKEN), so camera support on this board has been broken for a long
time (at least since 4.6 when the omap1_camera.c was removed from soc_camera).

The soc_camera driver is about to be removed, so drop camera
support from this board. Note that the soc_camera driver itself has
long since been deprecated and can't be compiled anymore (it depends
on BROKEN), so camera support on this board has been broken for a long
time (at least since 4.9 when the pxa_camera.c was removed from soc_camera).
Note that there is a new pxa_camera.c driver that replaced the old
soc_camera based driver, but using that would require these boards to
be converted to use the device tree.

* [PATCH 5/7] mach-pxa: palmz72/pcm990: remove soc_camera dependencies
@ 2020-06-26 11:53 ` Hans Verkuil

The soc_camera driver is about to be removed, so drop camera
support from this board. Note that the soc_camera driver itself has
long since been deprecated and can't be compiled anymore (it depends
on BROKEN), so camera support on this board has been broken for a long
time (at least since 4.9 when the pxa_camera.c was removed from soc_camera).
Note that there is a new pxa_camera.c driver that replaced the old
soc_camera based driver, but using that would require these boards to
be converted to use the device tree.

The soc_camera driver (and related soc_camera-dependent sensor
drivers) is obsolete and depends on BROKEN for a long time now.
Nobody is using it, so it is time to kill it off.

-The Soc-Camera Drivers
-======================
-
-Author: Guennadi Liakhovetski <g.liakhovetski@gmx.de>
-
-Terminology
------------
-
-The following terms are used in this document:
- - camera / camera device / camera sensor - a video-camera sensor chip, capable
- of connecting to a variety of systems and interfaces, typically uses i2c for
- control and configuration, and a parallel or a serial bus for data.
- - camera host - an interface, to which a camera is connected. Typically a
- specialised interface, present on many SoCs, e.g. PXA27x and PXA3xx, SuperH,
- i.MX27, i.MX31.
- - camera host bus - a connection between a camera host and a camera. Can be
- parallel or serial, consists of data and control lines, e.g. clock, vertical
- and horizontal synchronization signals.
-
-Purpose of the soc-camera subsystem
------------------------------------
-
-The soc-camera subsystem initially provided a unified API between camera host
-drivers and camera sensor drivers. Later the soc-camera sensor API has been
-replaced with the V4L2 standard subdev API. This also made camera driver re-use
-with non-soc-camera hosts possible. The camera host API to the soc-camera core
-has been preserved.
-
-Soc-camera implements a V4L2 interface to the user, currently only the "mmap"
-method is supported by host drivers. However, the soc-camera core also provides
-support for the "read" method.
-
-The subsystem has been designed to support multiple camera host interfaces and
-multiple cameras per interface, although most applications have only one camera
-sensor.
-
-Existing drivers
-----------------
-
-As of 3.7 there are seven host drivers in the mainline: atmel-isi.c,
-mx1_camera.c (broken, scheduled for removal), mx2_camera.c, mx3_camera.c,
-omap1_camera.c, pxa_camera.c, sh_mobile_ceu_camera.c, and multiple sensor
-drivers under drivers/media/i2c/soc_camera/.
-
-Camera host API
----------------
-
-A host camera driver is registered using the
-
-.. code-block:: none
-
- soc_camera_host_register(struct soc_camera_host *);
-
-function. The host object can be initialized as follows:
-
-.. code-block:: none
-
- struct soc_camera_host *ici;
- ici->drv_name = DRV_NAME;
- ici->ops = &camera_host_ops;
- ici->priv = pcdev;
- ici->v4l2_dev.dev = &pdev->dev;
- ici->nr = pdev->id;
-
-All camera host methods are passed in a struct soc_camera_host_ops:
-
-.. code-block:: none
-
- static struct soc_camera_host_ops camera_host_ops = {
- .owner = THIS_MODULE,
- .add = camera_add_device,
- .remove = camera_remove_device,
- .set_fmt = camera_set_fmt_cap,
- .try_fmt = camera_try_fmt_cap,
- .init_videobuf2 = camera_init_videobuf2,
- .poll = camera_poll,
- .querycap = camera_querycap,
- .set_bus_param = camera_set_bus_param,
- /* The rest of host operations are optional */
- };
-
-.add and .remove methods are called when a sensor is attached to or detached
-from the host. .set_bus_param is used to configure physical connection
-parameters between the host and the sensor. .init_videobuf2 is called by
-soc-camera core when a video-device is opened, the host driver would typically
-call vb2_queue_init() in this method. Further video-buffer management is
-implemented completely by the specific camera host driver. If the host driver
-supports non-standard pixel format conversion, it should implement a
-.get_formats and, possibly, a .put_formats operations. See below for more
-details about format conversion. The rest of the methods are called from
-respective V4L2 operations.
-
-Camera API
-----------
-
-Sensor drivers can use struct soc_camera_link, typically provided by the
-platform, and used to specify to which camera host bus the sensor is connected,
-and optionally provide platform .power and .reset methods for the camera. This
-struct is provided to the camera driver via the I2C client device platform data
-and can be obtained, using the soc_camera_i2c_to_link() macro. Care should be
-taken, when using soc_camera_vdev_to_subdev() and when accessing struct
-soc_camera_device, using v4l2_get_subdev_hostdata(): both only work, when
-running on an soc-camera host. The actual camera driver operation is implemented
-using the V4L2 subdev API. Additionally soc-camera camera drivers can use
-auxiliary soc-camera helper functions like soc_camera_power_on() and
-soc_camera_power_off(), which switch regulators, provided by the platform and call
-board-specific power switching methods. soc_camera_apply_board_flags() takes
-camera bus configuration capability flags and applies any board transformations,
-e.g. signal polarity inversion. soc_mbus_get_fmtdesc() can be used to obtain a
-pixel format descriptor, corresponding to a certain media-bus pixel format code.
-soc_camera_limit_side() can be used to restrict beginning and length of a frame
-side, based on camera capabilities.
-
-VIDIOC_S_CROP and VIDIOC_S_FMT behaviour
-----------------------------------------
-
-Above user ioctls modify image geometry as follows:
-
-VIDIOC_S_CROP: sets location and sizes of the sensor window. Unit is one sensor
-pixel. Changing sensor window sizes preserves any scaling factors, therefore
-user window sizes change as well.
-
-VIDIOC_S_FMT: sets user window. Should preserve previously set sensor window as
-much as possible by modifying scaling factors. If the sensor window cannot be
-preserved precisely, it may be changed too.
-
-In soc-camera there are two locations, where scaling and cropping can take
-place: in the camera driver and in the host driver. User ioctls are first passed
-to the host driver, which then generally passes them down to the camera driver.
-It is more efficient to perform scaling and cropping in the camera driver to
-save camera bus bandwidth and maximise the framerate. However, if the camera
-driver failed to set the required parameters with sufficient precision, the host
-driver may decide to also use its own scaling and cropping to fulfill the user's
-request.
-
-Camera drivers are interfaced to the soc-camera core and to host drivers over
-the v4l2-subdev API, which is completely functional, it doesn't pass any data.
-Therefore all camera drivers shall reply to .g_fmt() requests with their current
-output geometry. This is necessary to correctly configure the camera bus.
-.s_fmt() and .try_fmt() have to be implemented too. Sensor window and scaling
-factors have to be maintained by camera drivers internally. According to the
-V4L2 API all capture drivers must support the VIDIOC_CROPCAP ioctl, hence we
-rely on camera drivers implementing .cropcap(). If the camera driver does not
-support cropping, it may choose to not implement .s_crop(), but to enable
-cropping support by the camera host driver at least the .g_crop method must be
-implemented.
-
-User window geometry is kept in .user_width and .user_height fields in struct
-soc_camera_device and used by the soc-camera core and host drivers. The core
-updates these fields upon successful completion of a .s_fmt() call, but if these
-fields change elsewhere, e.g. during .s_crop() processing, the host driver is
-responsible for updating them.
-
-Format conversion
------------------
-
-V4L2 distinguishes between pixel formats, as they are stored in memory, and as
-they are transferred over a media bus. Soc-camera provides support to
-conveniently manage these formats. A table of standard transformations is
-maintained by soc-camera core, which describes, what FOURCC pixel format will
-be obtained, if a media-bus pixel format is stored in memory according to
-certain rules. E.g. if MEDIA_BUS_FMT_YUYV8_2X8 data is sampled with 8 bits per
-sample and stored in memory in the little-endian order with no gaps between
-bytes, data in memory will represent the V4L2_PIX_FMT_YUYV FOURCC format. These
-standard transformations will be used by soc-camera or by camera host drivers to
-configure camera drivers to produce the FOURCC format, requested by the user,
-using the VIDIOC_S_FMT ioctl(). Apart from those standard format conversions,
-host drivers can also provide their own conversion rules by implementing a
-.get_formats and, if required, a .put_formats methods.

From: Hans Verkuil @ 2020-06-26 11:53 UTC (permalink / raw)
To: linux-media; +Cc: linux-omap, linux-arm-kernel, Hans Verkuil, Arnd Bergmann
The soc_camera driver has been removed and all board files
that used it have been fixed. This header can now be removed
altogether.

* [PATCH 7/7] soc_camera.h: remove this unused header
@ 2020-06-26 11:53 ` Hans Verkuil
0 siblings, 0 replies; 33+ messages in thread
From: Hans Verkuil @ 2020-06-26 11:53 UTC (permalink / raw)
To: linux-media; +Cc: Hans Verkuil, linux-omap, Arnd Bergmann, linux-arm-kernel
The soc_camera driver has been removed and all board files
that used it have been fixed. This header can now be removed
altogether.
