Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab: - removal of sn9c102. This device driver was replaced a long time ago by gspca - solo6x10 and go7007 webcam drivers moved from staging into mainstream. They were waiting for an API to allow setting the image detection matrix - SDR drivers moved from staging into mainstream: sdr-msi3101 (renamed as msi2500) and rtl2832 - added SDR driver for airspy - added demux driver: si2165 - rework at several RC subsystem, making the code for RC-5 SZ variant to be added at the standard RC5 decoder - added decoder for the XMP IR protocol - tuner driver moved from staging into mainstream: msi3101 (renamed as msi001) - added documentation for some additional SDR pixfmt - some device tree bindings documented - added support for exynos3250 at s5p-jpeg - remove the obsolete, unmaintained and broken mx1_camera driver - added support for remote controllers at au0828 driver - added a RC driver: sunxi-cir - several driver fixes, enhancements and cleanups. * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (455 commits) [media] cx23885: fix UNSET/TUNER_ABSENT confusion [media] coda: fix build error by making reset control optional [media] radio-miropcm20: fix sparse NULL pointer warning [media] MAINTAINERS: Update go7007 pattern [media] MAINTAINERS: Update solo6x10 patterns [media] media: atmel-isi: add primary DT support [media] media: atmel-isi: convert the pdata from pointer to structure [media] media: atmel-isi: add v4l2 async probe support [media] rcar_vin: add devicetree support [media] media: pxa_camera device-tree support [media] media: mt9m111: add device-tree suppport [media] soc_camera: add support for dt binding soc_camera drivers [media] media: soc_camera: pxa_camera documentation device-tree support [media] media: mt9m111: add device-tree documentation [media] s5p-mfc: remove unnecessary calling to function video_devdata() [media] s5p-jpeg: add chroma subsampling adjustment for Exynos3250 [media] s5p-jpeg: Prevent erroneous downscaling for Exynos3250 SoC [media] s5p-jpeg: Assure proper crop rectangle initialization [media] s5p-jpeg: fix g_selection op [media] s5p-jpeg: Adjust jpeg_bound_align_image to Exynos3250 needs ...

-LICENSES AND DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION
-WARRANTIES OF MERCHANTABILITY, SUPPORT, AND FITNESS FOR A PARTICULAR
-PURPOSE AND NON-INFRINGEMENT.
-
-
-  1. SYSTEM REQUIREMENTS
-
-
-This driver requires Linux kernel 2.6.  Kernel 2.4 is not supported.  Using
-kernel 2.6.10 or later is recommended, as earlier kernels are known to have
-unstable USB 2.0 support.
-
-A fully built kernel source tree must be available.  Typically this will be
-linked from "/lib/modules/<KERNEL VERSION>/build" for convenience.  If this
-link does not exist, an extra parameter will need to be passed to the
-`make` command.
-
-All vendor-built kernels should already be configured properly.  However,
-for custom-built kernels, the following options need to be enabled in the
-kernel as built-in or modules:
-
-	CONFIG_MODULES           - Enable loadable module support
-	CONFIG_FW_LOADER         - Hotplug firmware loading support
-	CONFIG_I2C               - I2C support
-	CONFIG_VIDEO_DEV         - Video For Linux
-	CONFIG_SOUND             - Sound card support
-	CONFIG_SND               - Advanced Linux Sound Architecture
-	CONFIG_USB               - Support for Host-side USB
-	CONFIG_USB_EHCI_HCD      - EHCI HCD (USB 2.0) support
-
-Additionally, to use the example application, the following options need to
-be enabled in the ALSA section:
-
-	CONFIG_SND_MIXER_OSS     - OSS Mixer API
-	CONFIG_SND_PCM_OSS       - OSS PCM (digital audio) API
-
-The hotplug scripts, along with the fxload utility, must also be installed.
-These scripts can be obtained from <http://linux-hotplug.sourceforge.net/>.
-Hotplugging is used for loading firmware into the Cypruss EZ-USB chip using
-fxload and for loading firmware into the driver using the firmware agent.
-
-
-  2. COMPILING AND INSTALLING THE DRIVER
-
-
-Most users should be able to compile the driver by simply running:
-
-	$ make
-
-in the top-level directory of the driver kit.  First the kernel modules
-will be built, followed by the example applications.
-
-If the build system is unable to locate the kernel source tree for the
-currently-running kernel, or if the module should be built for a kernel
-other than the currently-running kernel, an additional parameter will need
-to be passed to make to specify the appropriate kernel source directory:
-
-	$ make KERNELSRC=/usr/src/linux-2.6.10-custom3
-
-Once the compile completes, the driver and firmware files should be
-installed by running:
-
-	$ make install
-
-The kernel modules will be placed in "/lib/modules/<KERNEL VERSION>/extra"
-and the firmware files will be placed in the appropriate hotplug firmware
-directory, usually /lib/firmware.  In addition, USB maps and scripts will
-be placed in /etc/hotplug/usb to enable fxload to initialize the EZ-USB
-control chip when the device is connected.
-
-
-  3. PAL/SECAM TUNER CONFIGURATION (TV402U-EU only)
-
-
-The PAL model of the Plextor ConvertX TV402U may require additional
-configuration to correctly select the appropriate TV frequency band and
-audio subchannel.
-
-Users with a device other than the Plextor ConvertX TV402U-EU should skip
-this section.
-
-The wide variety of PAL TV systems used in Europe requires that additional
-information about the local TV standards be passed to the driver in order
-to properly tune TV channels.  The two necessary parameters are (a) the PAL
-TV band, and (b) the audio subchannel format in use.
-
-In many cases, the appropriate TV band selection is passed to the driver
-from applications.  However, in some cases, the application only specifies
-that the driver should use PAL but not the specific information about the
-appropriate TV band.  To work around this issue, the correct TV band may be
-specified in the "force_band" parameter to the wis-sony-tuner module:
-
-     TV band           force_band
-     -------           ----------
-     PAL B/G                B
-     PAL I                  I
-     PAL D/K                D
-     SECAM L                L
-
-If the "force_band" parameter is specified, the driver will ignore any TV
-band specified by applications and will always use the band provided in the
-module parameter.
-
-The other parameter that can be specified is the audio subchannel format.
-There are several stereo audio carrier systems in use, including NICAM and
-three varieties of A2.  To receive audio broadcast on one of these stereo
-carriers, the "force_mpx_mode" parameter must be specified to the
-wis-sony-tuner module.
-
-     TV band           Audio subcarrier       force_mpx_mode
-     -------           ----------------       --------------
-     PAL B/G            Mono (default)               1
-     PAL B/G                  A2                     2
-     PAL B/G                 NICAM                   3
-     PAL I              Mono (default)               4
-     PAL I                   NICAM                   5
-     PAL D/K            Mono (default)               6
-     PAL D/K                 A2 (1)                  7
-     PAL D/K                 A2 (2)                  8
-     PAL D/K                 A2 (3)                  9
-     PAL D/K                 NICAM                  10
-     SECAM L            Mono (default)              11
-     SECAM L                 NICAM                  12
-
-If the "force_mpx_mode" parameter is not specified, the correct mono-only
-mode will be chosen based on the TV band.  However, the tuner will not
-receive stereo audio or bilingual broadcasts correctly.
-
-To pass the "force_band" or "force_mpx_mode" parameters to the
-wis-sony-tuner module, the following line must be added to the modprobe
-configuration file, which varies from one Linux distribution to another.
-
-     options wis-sony-tuner force_band=B force_mpx_mode=2
-
-The above example would force the tuner to the PAL B/G TV band and receive
-stereo audio broadcasts on the A2 carrier.
-
-To verify that the configuration has been placed in the correct location,
-execute:
-
-	$ modprobe -c | grep wis-sony-tuner
-
-If the configuration line appears, then modprobe will pass the parameters
-correctly the next time the wis-sony-tuner module is loaded into the
-kernel.
-
-
-  4. TESTING THE DRIVER
-
-
-Because few Linux applications are able to correctly capture from
-Video4Linux2 devices with only compressed formats supported, the new driver
-should be tested with the "gorecord" application in the apps/ directory.
-
-First connect a video source to the device, such as a DVD player or VCR.
-This will be captured to a file for testing the driver.  If an input source
-is unavailable, a test file can still be captured, but the video will be
-black and the audio will be silent.
-
-This application will auto-detect the V4L2 and ALSA/OSS device names of the
-hardware and will record video and audio to an AVI file for a specified
-number of seconds.  For example:
-
-	$ apps/gorecord -duration 60 capture.avi
-
-If this application does not successfully record an AVI file, the error
-messages produced by gorecord and recorded in the system log (usually in
-/var/log/messages) should provide information to help resolve the problem.
-
-Supplying no parameters to gorecord will cause it to probe the available
-devices and exit.  Use the -help flag for usage information.
-
-
-  5. USING THE DRIVER
-
-
-The V4L2 device implemented by the driver provides a standard compressed
-format API, within the following criteria:
-
-  * Applications that only support the original Video4Linux1 API will not
-    be able to communicate with this driver at all.
-
-  * No raw video modes are supported, so applications like xawtv that
-    expect only uncompressed video will not function.
-
-  * Supported compression formats are: Motion-JPEG, MPEG1, MPEG2 and MPEG4.
-
-  * MPEG video formats are delivered as Video Elementary Streams only.
-    Program Stream (PS), Transport Stream (TS) and Packetized Elementary
-    Stream (PES) formats are not supported.
-
-  * Video parameters such as format and input port may not be changed while
-    the encoder is active.
-
-  * The audio capture device only functions when the video encoder is
-    actively capturing video.  Attempts to read from the audio device when
-    the encoder is inactive will result in an I/O error.
-
-  * The native format of the audio device is 48Khz 2-channel 16-bit
-    little-endian PCM, delivered through the ALSA system.  No audio
-    compression is implemented in the hardware.  ALSA may convert to other
-    uncompressed formats on the fly.
-
-The include/ directory contains a C header file describing non-standard
-features of the GO7007SB encoder, which are described below:
-
-
-  GO7007IOC_S_COMP_PARAMS, GO7007IOC_G_COMP_PARAMS
-
-    These ioctls are used to negotiate general compression parameters.
-
-    To query the current parameters, call the GO7007IOC_G_COMP_PARAMS ioctl
-    with a pointer to a struct go7007_comp_params.  If the driver is not
-    set to MPEG format, the EINVAL error code will be returned.
-
-    To change the current parameters, initialize all fields of a struct
-    go7007_comp_params and call the GO7007_IOC_S_COMP_PARAMS ioctl with a
-    pointer to this structure.  The driver will return the current
-    parameters with any necessary changes to conform to the limitations of
-    the hardware or current compression mode.  Any or all fields can be set
-    to zero to request a reasonable default value.  If the driver is not
-    set to MPEG format, the EINVAL error code will be returned.  When I/O
-    is in progress, the EBUSY error code will be returned.
-
-    Fields in struct go7007_comp_params:
-
-	__u32                        The maximum number of frames in each
-	  gop_size                   Group Of Pictures; i.e. the maximum
-				     number of frames minus one between
-				     each key frame.
-
-	__u32                        The maximum number of sequential
-	  max_b_frames               bidirectionally-predicted frames.
-				     (B-frames are not yet supported.)
-
-	enum go7007_aspect_ratio     The aspect ratio to be encoded in the
-	  aspect_ratio               meta-data of the compressed format.
-
-				     Choices are:
-					GO7007_ASPECT_RATIO_1_1
-					GO7007_ASPECT_RATIO_4_3_NTSC
-					GO7007_ASPECT_RATIO_4_3_PAL
-					GO7007_ASPECT_RATIO_16_9_NTSC
-					GO7007_ASPECT_RATIO_16_9_PAL
-
-	__u32                        Bit-wise OR of control flags (below)
-	  flags
-
-    Flags in struct go7007_comp_params:
-
-	GO7007_COMP_CLOSED_GOP       Only produce self-contained GOPs, used
-				     to produce streams appropriate for
-				     random seeking.
-
-	GO7007_COMP_OMIT_SEQ_HEADER  Omit the stream sequence header.
-
-
-  GO7007IOC_S_MPEG_PARAMS, GO7007IOC_G_MPEG_PARAMS
-
-    These ioctls are used to negotiate MPEG-specific stream parameters when
-    the pixelformat has been set to V4L2_PIX_FMT_MPEG.
-
-    To query the current parameters, call the GO7007IOC_G_MPEG_PARAMS ioctl
-    with a pointer to a struct go7007_mpeg_params.  If the driver is not
-    set to MPEG format, the EINVAL error code will be returned.
-
-    To change the current parameters, initialize all fields of a struct
-    go7007_mpeg_params and call the GO7007_IOC_S_MPEG_PARAMS ioctl with a
-    pointer to this structure.  The driver will return the current
-    parameters with any necessary changes to conform to the limitations of
-    the hardware or selected MPEG mode.  Any or all fields can be set to
-    zero to request a reasonable default value.  If the driver is not set
-    to MPEG format, the EINVAL error code will be returned.  When I/O is in
-    progress, the EBUSY error code will be returned.
-
-    Fields in struct go7007_mpeg_params:
-
-	enum go7007_mpeg_video_standard
-	  mpeg_video_standard        The MPEG video standard in which to
-				     compress the video.
-
-				     Choices are:
-					GO7007_MPEG_VIDEO_MPEG1
-					GO7007_MPEG_VIDEO_MPEG2
-					GO7007_MPEG_VIDEO_MPEG4
-
-	__u32                        Bit-wise OR of control flags (below)
-	  flags
-
-	__u32                        The profile and level indication to be
-	  pali                       stored in the sequence header.  This
-				     is only used as an indicator to the
-				     decoder, and does not affect the MPEG
-				     features used in the video stream.
-				     Not valid for MPEG1.
-
-				     Choices for MPEG2 are:
-					GO7007_MPEG2_PROFILE_MAIN_MAIN
-
-				     Choices for MPEG4 are:
-					GO7007_MPEG4_PROFILE_S_L0
-					GO7007_MPEG4_PROFILE_S_L1
-					GO7007_MPEG4_PROFILE_S_L2
-					GO7007_MPEG4_PROFILE_S_L3
-					GO7007_MPEG4_PROFILE_ARTS_L1
-					GO7007_MPEG4_PROFILE_ARTS_L2
-					GO7007_MPEG4_PROFILE_ARTS_L3
-					GO7007_MPEG4_PROFILE_ARTS_L4
-					GO7007_MPEG4_PROFILE_AS_L0
-					GO7007_MPEG4_PROFILE_AS_L1

-					GO7007_MPEG4_PROFILE_AS_L3
-					GO7007_MPEG4_PROFILE_AS_L4
-					GO7007_MPEG4_PROFILE_AS_L5
-
-    Flags in struct go7007_mpeg_params:
-
-	GO7007_MPEG_FORCE_DVD_MODE   Force all compression parameters and
-				     bitrate control settings to comply
-				     with DVD MPEG2 stream requirements.
-				     This overrides most compression and
-				     bitrate settings!
-
-	GO7007_MPEG_OMIT_GOP_HEADER  Omit the GOP header.
-
-	GO7007_MPEG_REPEAT_SEQHEADER Repeat the MPEG sequence header at
-				     the start of each GOP.
-
-
-  GO7007IOC_S_BITRATE, GO7007IOC_G_BITRATE
-
-    These ioctls are used to set and query the target bitrate value for the
-    compressed video stream.  The bitrate may be selected by storing the
-    target bits per second in an int and calling GO7007IOC_S_BITRATE with a
-    pointer to the int.  The bitrate may be queried by calling
-    GO7007IOC_G_BITRATE with a pointer to an int where the current bitrate
-    will be stored.
-
-    Note that this is the primary means of controlling the video quality
-    for all compression modes, including V4L2_PIX_FMT_MJPEG.  The
-    VIDIOC_S_JPEGCOMP ioctl is not supported.
-
-
-----------------------------------------------------------------------------
-		   Installing the WIS PCI Voyager Driver
----------------------------------------------------------------------------
-
-The WIS PCI Voyager driver requires several patches to the Linux 2.6.11.x
-kernel source tree before compiling the driver.  These patches update the
-in-kernel SAA7134 driver to the newest development version and patch bugs
-in the TDA8290/TDA8275 tuner driver.
-
-The following patches must be downloaded from Gerd Knorr's website and
-applied in the order listed:
-
-	http://dl.bytesex.org/patches/2.6.11-2/i2c-tuner
-	http://dl.bytesex.org/patches/2.6.11-2/i2c-tuner2
-	http://dl.bytesex.org/patches/2.6.11-2/v4l2-api-mpeg
-	http://dl.bytesex.org/patches/2.6.11-2/saa7134-update
-
-The following patches are included with this SDK and can be applied in any
-order:
-
-	patches/2.6.11/saa7134-voyager.diff
-	patches/2.6.11/tda8275-newaddr.diff
-	patches/2.6.11/tda8290-ntsc.diff
-
-Check to make sure the CONFIG_VIDEO_SAA7134 option is enabled in the kernel
-configuration, and build and install the kernel.
-
-After rebooting into the new kernel, the GO7007 driver can be compiled and
-installed:
-
-	$ make SAA7134_BUILD=y
-	$ make install
-	$ modprobe saa7134-go7007
-
-There will be two V4L video devices associated with the PCI Voyager.  The
-first device (most likely /dev/video0) provides access to the raw video
-capture mode of the SAA7133 device and is used to configure the source
-video parameters and tune the TV tuner.  This device can be used with xawtv
-or other V4L(2) video software as a standard uncompressed device.
-
-The second device (most likely /dev/video1) provides access to the
-compression functions of the GO7007.  It can be tested using the gorecord
-application in the apps/ directory of this SDK:
-
-	$ apps/gorecord -vdevice /dev/video1 -noaudio test.avi
-
-Currently the frame resolution is fixed at 720x480 (NTSC) or 720x576 (PAL),
-and the video standard must be specified to both the raw and the compressed
-video devices (xawtv and gorecord, for example).
-
-
---------------------------------------------------------------------------
-RELEASE NOTES FOR WIS GO7007SB LINUX DRIVER
----------------------------------------------------------------------------
-
-Last updated: 5 November 2005
-
- - Release 0.9.7 includes new support for using udev to run fxload.  The
-   install script should automatically detect whether the old hotplug
-   scripts or the new udev rules should be used.  To force the use of
-   hotplug, run "make install USE_UDEV=n".  To force the use of udev, run
-   "make install USE_UDEV=y".
-
- - Motion detection is supported but undocumented.  Try the `modet` app
-   for a demonstration of how to use the facility.
-
- - Using USB2.0 devices such as the TV402U with USB1.1 HCDs or hubs can
-   cause buffer overruns and frame drops, even at low framerates, due to
-   inconsistency in the bitrate control mechanism.
-
- - On devices with an SAA7115, including the Plextor ConvertX, video height
-   values of 96, 128, 160, 192, 256, 320, and 384 do not work in NTSC mode.
-   All valid heights up to 512 work correctly in PAL mode.
-
- - The WIS Star Trek and PCI Voyager boards have no support yet for audio
-   or the TV tuner.

-4. Overview and features
-========================
-This driver attempts to support the video interface of the devices assembling
-the SONiX SN9C101, SN9C102, SN9C103, SN9C105 and SN9C120 PC Camera Controllers
-("SN9C1xx" from now on).
-
-The driver relies on the Video4Linux2 and USB core modules. It has been
-designed to run properly on SMP systems as well.
-
-The latest version of the SN9C1xx driver can be found at the following URL:
-http://www.linux-projects.org/
-
-Some of the features of the driver are:
-
-- full compliance with the Video4Linux2 API (see also "Notes for V4L2
-  application developers" paragraph);
-- available mmap or read/poll methods for video streaming through isochronous
-  data transfers;
-- automatic detection of image sensor;
-- support for built-in microphone interface;
-- support for any window resolutions and optional panning within the maximum
-  pixel area of image sensor;
-- image downscaling with arbitrary scaling factors from 1, 2 and 4 in both
-  directions (see "Notes for V4L2 application developers" paragraph);
-- two different video formats for uncompressed or compressed data in low or
-  high compression quality (see also "Notes for V4L2 application developers"
-  and "Video frame formats" paragraphs);
-- full support for the capabilities of many of the possible image sensors that
-  can be connected to the SN9C1xx bridges, including, for instance, red, green,
-  blue and global gain adjustments and exposure (see "Supported devices"
-  paragraph for details);
-- use of default color settings for sunlight conditions;
-- dynamic I/O interface for both SN9C1xx and image sensor control and
-  monitoring (see "Optional device control through 'sysfs'" paragraph);
-- dynamic driver control thanks to various module parameters (see "Module
-  parameters" paragraph);
-- up to 64 cameras can be handled at the same time; they can be connected and
-  disconnected from the host many times without turning off the computer, if
-  the system supports hotplugging;
-- no known bugs.
-
-
-5. Module dependencies
-======================
-For it to work properly, the driver needs kernel support for Video4Linux and
-USB.
-
-The following options of the kernel configuration file must be enabled and
-corresponding modules must be compiled:
-
-	# Multimedia devices
-	#
-	CONFIG_VIDEO_DEV=m
-
-To enable advanced debugging functionality on the device through /sysfs:
-
-	# Multimedia devices
-	#
-	CONFIG_VIDEO_ADV_DEBUG=y
-
-	# USB support
-	#
-	CONFIG_USB=m
-
-In addition, depending on the hardware being used, the modules below are
-necessary:
-
-	# USB Host Controller Drivers
-	#
-	CONFIG_USB_EHCI_HCD=m
-	CONFIG_USB_UHCI_HCD=m
-	CONFIG_USB_OHCI_HCD=m
-
-The SN9C103, SN9c105 and SN9C120 controllers also provide a built-in microphone
-interface. It is supported by the USB Audio driver thanks to the ALSA API:
-
-	# Sound
-	#
-	CONFIG_SOUND=y
-
-	# Advanced Linux Sound Architecture
-	#
-	CONFIG_SND=m
-
-	# USB devices
-	#
-	CONFIG_SND_USB_AUDIO=m
-
-And finally:
-
-	# USB Multimedia devices
-	#
-	CONFIG_USB_SN9C102=m
-
-
-6. Module loading
-=================
-To use the driver, it is necessary to load the "sn9c102" module into memory
-after every other module required: "videodev", "v4l2_common", "compat_ioctl32",
-"usbcore" and, depending on the USB host controller you have, "ehci-hcd",
-"uhci-hcd" or "ohci-hcd".
-
-Loading can be done as shown below:
-
-	[root@localhost home]# modprobe sn9c102
-
-Note that the module is called "sn9c102" for historic reasons, although it
-does not just support the SN9C102.
-
-At this point all the devices supported by the driver and connected to the USB
-ports should be recognized. You can invoke "dmesg" to analyze kernel messages
-and verify that the loading process has gone well:
-
-	[user@localhost home]$ dmesg
-
-or, to isolate all the kernel messages generated by the driver:
-
-	[user@localhost home]$ dmesg | grep sn9c102
-
-
-7. Module parameters
-====================
-Module parameters are listed below:
--------------------------------------------------------------------------------
-Name:           video_nr
-Type:           short array (min = 0, max = 64)
-Syntax:         <-1|n[,...]>
-Description:    Specify V4L2 minor mode number:
-		-1 = use next available
-		 n = use minor number n
-		You can specify up to 64 cameras this way.
-		For example:
-		video_nr=-1,2,-1 would assign minor number 2 to the second
-		recognized camera and use auto for the first one and for every
-		other camera.
-Default:        -1
--------------------------------------------------------------------------------
-Name:           force_munmap
-Type:           bool array (min = 0, max = 64)
-Syntax:         <0|1[,...]>
-Description:    Force the application to unmap previously mapped buffer memory
-		before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not
-		all the applications support this feature. This parameter is
-		specific for each detected camera.
-		0 = do not force memory unmapping
-		1 = force memory unmapping (save memory)
-Default:        0
--------------------------------------------------------------------------------
-Name:           frame_timeout
-Type:           uint array (min = 0, max = 64)
-Syntax:         <0|n[,...]>
-Description:    Timeout for a video frame in seconds before returning an I/O
-		error; 0 for infinity. This parameter is specific for each
-		detected camera and can be changed at runtime thanks to the
-		/sys filesystem interface.
-Default:        2
--------------------------------------------------------------------------------
-Name:           debug
-Type:           ushort
-Syntax:         <n>
-Description:    Debugging information level, from 0 to 3:
-		0 = none (use carefully)
-		1 = critical errors
-		2 = significant information
-		3 = more verbose messages
-		Level 3 is useful for testing only. It also shows some more
-		information about the hardware being detected.
-		This parameter can be changed at runtime thanks to the /sys
-		filesystem interface.
-Default:        2
--------------------------------------------------------------------------------
-
-
-8. Optional device control through "sysfs" [1]
-==========================================
-If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled,
-it is possible to read and write both the SN9C1xx and the image sensor
-registers by using the "sysfs" filesystem interface.
-
-Every time a supported device is recognized, a write-only file named "green" is
-created in the /sys/class/video4linux/videoX directory. You can set the green
-channel's gain by writing the desired value to it. The value may range from 0
-to 15 for the SN9C101 or SN9C102 bridges, from 0 to 127 for the SN9C103,
-SN9C105 and SN9C120 bridges.
-Similarly, only for the SN9C103, SN9C105 and SN9C120 controllers, blue and red
-gain control files are available in the same directory, for which accepted
-values may range from 0 to 127.
-
-There are other four entries in the directory above for each registered camera:
-"reg", "val", "i2c_reg" and "i2c_val". The first two files control the
-SN9C1xx bridge, while the other two control the sensor chip. "reg" and
-"i2c_reg" hold the values of the current register index where the following
-reading/writing operations are addressed at through "val" and "i2c_val". Their
-use is not intended for end-users. Note that "i2c_reg" and "i2c_val" will not
-be created if the sensor does not actually support the standard I2C protocol or
-its registers are not 8-bit long. Also, remember that you must be logged in as
-root before writing to them.
-
-As an example, suppose we were to want to read the value contained in the
-register number 1 of the sensor register table - which is usually the product
-identifier - of the camera registered as "/dev/video0":
-
-	[root@localhost #] cd /sys/class/video4linux/video0
-	[root@localhost #] echo 1 > i2c_reg
-	[root@localhost #] cat i2c_val
-
-Note that "cat" will fail if sensor registers cannot be read.
-
-Now let's set the green gain's register of the SN9C101 or SN9C102 chips to 2:
-
-	[root@localhost #] echo 0x11 > reg
-	[root@localhost #] echo 2 > val
-
-Note that the SN9C1xx always returns 0 when some of its registers are read.
-To avoid race conditions, all the I/O accesses to the above files are
-serialized.
-The sysfs interface also provides the "frame_header" entry, which exports the
-frame header of the most recent requested and captured video frame. The header
-is always 18-bytes long and is appended to every video frame by the SN9C1xx
-controllers. As an example, this additional information can be used by the user
-application for implementing auto-exposure features via software.
-
-The following table describes the frame header exported by the SN9C101 and
-SN9C102:

-
-"Yes" means that the pair is supported by the driver, while "No" means that the
-pair does not exist or is not supported by the driver.
-
-Only some of the available control settings of each image sensor are supported
-through the V4L2 interface.
-
-Donations of new models for further testing and support would be much
-appreciated. Non-available hardware will not be supported by the author of this
-driver.
-
-
-10. Notes for V4L2 application developers
-=========================================
-This driver follows the V4L2 API specifications. In particular, it enforces two
-rules:
-
-- exactly one I/O method, either "mmap" or "read", is associated with each
-file descriptor. Once it is selected, the application must close and reopen the
-device to switch to the other I/O method;
-
-- although it is not mandatory, previously mapped buffer memory should always
-be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's.
-The same number of buffers as before will be allocated again to match the size
-of the new video frames, so you have to map the buffers again before any I/O
-attempts on them.
-
-Consistently with the hardware limits, this driver also supports image
-downscaling with arbitrary scaling factors from 1, 2 and 4 in both directions.
-However, the V4L2 API specifications don't correctly define how the scaling
-factor can be chosen arbitrarily by the "negotiation" of the "source" and
-"target" rectangles. To work around this flaw, we have added the convention
-that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the
-scaling factor is restored to 1.
-
-This driver supports two different video formats: the first one is the "8-bit
-Sequential Bayer" format and can be used to obtain uncompressed video data
-from the device through the current I/O method, while the second one provides
-either "raw" compressed video data (without frame headers not related to the
-compressed data) or standard JPEG (with frame headers). The compression quality
-may vary from 0 to 1 and can be selected or queried thanks to the
-VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP V4L2 ioctl's. For maximum flexibility,
-both the default active video format and the default compression quality
-depend on how the image sensor being used is initialized.
-
-
-11. Video frame formats [1]
-=======================
-The SN9C1xx PC Camera Controllers can send images in two possible video
-formats over the USB: either native "Sequential RGB Bayer" or compressed.
-The compression is used to achieve high frame rates. With regard to the
-SN9C101, SN9C102 and SN9C103, the compression is based on the Huffman encoding
-algorithm described below, while with regard to the SN9C105 and SN9C120 the
-compression is based on the JPEG standard.
-The current video format may be selected or queried from the user application
-by calling the VIDIOC_S_FMT or VIDIOC_G_FMT ioctl's, as described in the V4L2
-API specifications.
-
-The name "Sequential Bayer" indicates the organization of the red, green and
-blue pixels in one video frame. Each pixel is associated with a 8-bit long
-value and is disposed in memory according to the pattern shown below:
-
-B[0]   G[1]    B[2]    G[3]    ...   B[m-2]         G[m-1]
-G[m]   R[m+1]  G[m+2]  R[m+2]  ...   G[2m-2]        R[2m-1]
-...
-...                                  B[(n-1)(m-2)]  G[(n-1)(m-1)]
-...                                  G[n(m-2)]      R[n(m-1)]
-
-The above matrix also represents the sequential or progressive read-out mode of
-the (n, m) Bayer color filter array used in many CCD or CMOS image sensors.
-
-The Huffman compressed video frame consists of a bitstream that encodes for
-every R, G, or B pixel the difference between the value of the pixel itself and
-some reference pixel value. Pixels are organised in the Bayer pattern and the
-Bayer sub-pixels are tracked individually and alternatingly. For example, in
-the first line values for the B and G1 pixels are alternatingly encoded, while
-in the second line values for the G2 and R pixels are alternatingly encoded.
-
-The pixel reference value is calculated as follows:
-- the 4 top left pixels are encoded in raw uncompressed 8-bit format;
-- the value in the top two rows is the value of the pixel left of the current
-  pixel;
-- the value in the left column is the value of the pixel above the current
-  pixel;
-- for all other pixels, the reference value is the average of the value of the
-  pixel on the left and the value of the pixel above the current pixel;
-- there is one code in the bitstream that specifies the value of a pixel
-  directly (in 4-bit resolution);
-- pixel values need to be clamped inside the range [0..255] for proper
-  decoding.
-
-The algorithm purely describes the conversion from compressed Bayer code used
-in the SN9C101, SN9C102 and SN9C103 chips to uncompressed Bayer. Additional
-steps are required to convert this to a color image (i.e. a color interpolation
-algorithm).
-
-The following Huffman codes have been found:
-0: +0 (relative to reference pixel value)
-100: +4
-101: -4?
-1110xxxx: set absolute value to xxxx.0000
-1101: +11
-1111: -11
-11001: +20
-110000: -20
-110001: ??? - these codes are apparently not used
-
-[1] The Huffman compression algorithm has been reverse-engineered and
-    documented by Bertrik Sikken.

-/*
-   OVERVIEW.
-   This is a small interface that allows you to add support for any CCD/CMOS
-   image sensors connected to the SN9C1XX bridges. The entire API is documented
-   below. In the most general case, to support a sensor there are three steps
-   you have to follow:
-   1) define the main "sn9c102_sensor" structure by setting the basic fields;
-   2) write a probing function to be called by the core module when the USB
-      camera is recognized, then add both the USB ids and the name of that
-      function to the two corresponding tables in sn9c102_devtable.h;
-   3) implement the methods that you want/need (and fill the rest of the main
-      structure accordingly).
-   "sn9c102_pas106b.c" is an example of all this stuff. Remember that you do
-   NOT need to touch the source code of the core module for the things to work
-   properly, unless you find bugs or flaws in it. Finally, do not forget to
-   read the V4L2 API for completeness.

-	   cover the whole array of pixels. The V4L2 API defines another

-	   of pixels, so no particular initialization is needed, if you have
-	   defined the correct default bounds in the structures.
-	   See the V4L2 API for further details.
-	   NOTE: once you have defined the bounds of the active window
