+Todo:
+	- checkpatch.pl cleanups
+	- sparse cleanups
+	- lots of little modules, should be merged together
+	  and added to the build.
+	- testing?
+	- handle churn in v4l layer.
+
+Please send patchs to Greg Kroah-Hartman <greg@kroah.com> and Cc: Ross

+
+Pete Eberlein <pete@sensoray.com>
+
+The driver was originally released under the GPL and is currently hosted at:
+http://nikosapi.org/wiki/index.php/WIS_Go7007_Linux_driver
+The go7007 firmware can be acquired from the package on the site above.
+
+I've modified the driver to support the following Video4Linux2 MPEG
+controls, with acceptable values:
+
+V4L2_CID_MPEG_STREAM_TYPE	V4L2_MPEG_STREAM_TYPE_MPEG2_DVD
+				V4L2_MPEG_STREAM_TYPE_MPEG_ELEM

+MICRONAS USA, INC., MAKES NO WARRANTIES TO ANY PERSON OR ENTITY WITH
+RESPECT TO THE SOFTWARE OR ANY DERIVATIVES THEREOF OR ANY SERVICES OR
+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_HOTPLUG           - Support for hot-pluggable devices
+	CONFIG_MODULES           - Enable loadable module support
+	CONFIG_KMOD              - Automatic kernel module loading
+	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_DEVICEFS      - USB device filesystem
+	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.

+					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_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.

+	  This option allows you to select a number of drivers that are
+	  not of the "normal" Linux kernel quality level.  These drivers
+	  are placed here in order to get a wider audience for use of
+	  them.  Please note that these drivers are under heavy
+	  development, may or may not work, and may contain userspace
+	  interfaces that most likely will be changed in the near
+	  future.
+
+	  Using any of these drivers will taint your kernel which might
+	  affect support options from both the community, and various
+	  commercial support orginizations.
+
+	  If you wish to work on these drivers, to help improve them, or
+	  to report problems you have with them, please see the
+	  driver_name.README file in the drivers/staging/ directory to
+	  see what needs to be worked on, and who to contact.
+
