The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

+        ---help---
+          This option allows you to select a number of media drivers that
+	  don't have the "normal" Linux kernel quality level.
+	  Most of them don't follow properly the V4L, DVB and/or RC API's,
+	  so, they won't likely work fine with the existing applications.
+	  That also means that, once fixed, their API's will change to match
+	  the existing ones.
+
+          If you wish to work on these drivers, to help improve them, or
+          to report problems you have with them, please use the
+	  linux-media@vger.kernel.org mailing list.
+
+          If in doubt, say N here.

+
+
+
+SUPPORTED HARDWARE
+------------------
+
+This driver is intended for use with hardware having USB ID 05e1:0408.
+Two kinds of EasyCAP have this USB ID, namely:
+
+    *  EasyCAP USB 2.0 Video Adapter with Audio, Model DC60,
+       having input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
+
+    *  EasyCAP002 4-Channel USB 2.0 DVR, having input cables labelled
+       1, 2, 3, 4 and an unlabelled input cable for a microphone.
+
+
+BUILD OPTIONS AND DEPENDENCIES
+------------------------------
+
+Unless EASYCAP_DEBUG is defined during compilation it will not be possible
+to select a debug level at the time of module installation.
+
+
+KNOWN RUNTIME ISSUES
+--------------------
+
+(1) Intentionally, this driver will not stream material which is unambiguously
+identified by the hardware as copy-protected.  Normal video output will be
+present for about a minute but will then freeze when this situation arises.
+
+(2) The controls for luminance, contrast, saturation, hue and volume may not
+always work properly.
+
+(3) Reduced-resolution S-Video seems to suffer from moire artefacts.
+
+
+INPUT NUMBERING
+---------------
+
+For the EasyCAP with S-VIDEO input cable the driver regards a request for
+inputs numbered 0 or 1 as referring to CVBS and a request for input
+numbered 5 as referring to S-VIDEO.
+
+For the EasyCAP with four CVBS inputs the driver expects to be asked for
+any one of inputs numbered 1,2,3,4.  If input 0 is asked for, it is
+interpreted as input 1.
+
+
+MODULE PARAMETERS
+-----------------
+
+Three module parameters are defined:
+
+debug      the easycap module is configured at diagnostic level n (0 to 9)
+gain       audio gain level n (0 to 31, default is 16)
+bars       whether to display testcard bars when incoming video signal is lost
+           0 => no, 1 => yes (default)
+
+
+SUPPORTED TV STANDARDS AND RESOLUTIONS
+--------------------------------------
+
+The following TV standards are natively supported by the hardware and are
+usable as (for example) the "norm=" parameter in the mplayer command:
+
+    PAL_BGHIN,    NTSC_N_443,
+    PAL_Nc,       NTSC_N,
+    SECAM,        NTSC_M,        NTSC_M_JP,
+    PAL_60,       NTSC_443,
+    PAL_M.
+
+In addition, the driver offers "custom" pseudo-standards with a framerate
+which is 20% of the usual framerate.  These pseudo-standards are named:
+
+    PAL_BGHIN_SLOW,    NTSC_N_443_SLOW,
+    PAL_Nc_SLOW,       NTSC_N_SLOW,
+    SECAM_SLOW,        NTSC_M_SLOW,        NTSC_M_JP_SLOW,
+    PAL_60_SLOW,       NTSC_443_SLOW,
+    PAL_M_SLOW.
+
+
+The available picture sizes are:
+
+     at 25 frames per second:   720x576, 704x576, 640x480, 360x288, 320x240;
+     at 30 frames per second:   720x480, 640x480, 360x240, 320x240.
+
+
+WHAT'S TESTED AND WHAT'S NOT
+----------------------------
+
+This driver is known to work with mplayer, mencoder, tvtime, zoneminder,
+xawtv, gstreamer and sufficiently recent versions of vlc.  An interface
+to ffmpeg is implemented, but serious audio-video synchronization problems
+remain.
+
+The driver is designed to support all the TV standards accepted by the
+hardware, but as yet it has actually been tested on only a few of these.
+
+I have been unable to test and calibrate the S-video input myself because I
+do not possess any equipment with S-video output.
+
+
+UDEV RULES
+----------
+
+In order that the special files /dev/easycap0 and /dev/easysnd1 are created
+with conveniently relaxed permissions when the EasyCAP is plugged in, a file
+is preferably to be provided in directory /etc/udev/rules.d with content:
+
+ACTION!="add|change", GOTO="easycap_rules_end"
+ATTRS{idVendor}=="05e1", ATTRS{idProduct}=="0408", \
+	MODE="0666", OWNER="root", GROUP="root"
+LABEL="easycap_rules_end"
+
+
+MODPROBE CONFIGURATION
+----------------------
+
+The easycap module is in competition with the module snd-usb-audio for the
+EasyCAP's audio channel, and its installation can be aided by providing a
+file in directory /etc/modprobe.d with content:
+
+options easycap  gain=16 bars=1
+install easycap /sbin/rmmod snd-usb-audio; /sbin/modprobe --ignore-install easycap
+
+
+ACKNOWLEGEMENTS AND REFERENCES
+------------------------------
+This driver makes use of information contained in the Syntek Semicon DC-1125
+Driver, presently maintained at http://sourceforge.net/projects/syntekdriver/
+by Nicolas Vivien.  Particularly useful has been a patch to the latter driver
+provided by Ivor Hewitt in January 2009.  The NTSC implementation is taken
+from the work of Ben Trask.

+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.
+
+				     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_L2
+					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.

+1. Both ir-kbd-i2c and lirc_zilog provide support for RX events for
+the chips supported by lirc_zilog.  Before moving lirc_zilog out of staging:
+
+a. ir-kbd-i2c needs a module parameter added to allow the user to tell
+   ir-kbd-i2c to ignore Z8 IR units.
+
+b. lirc_zilog should provide Rx key presses to the rc core like ir-kbd-i2c
+   does.
+
+
+2. lirc_zilog module ref-counting need examination.  It has not been
+verified that cdev and lirc_dev will take the proper module references on
+lirc_zilog to prevent removal of lirc_zilog when the /dev/lircN device node
+is open.
+
+(The good news is ref-counting of lirc_zilog internal structures appears to be
+complete.  Testing has shown the cx18 module can be unloaded out from under
+irw + lircd + lirc_dev, with the /dev/lirc0 device node open, with no adverse
+effects.  The cx18 module could then be reloaded and irw properly began
+receiving button presses again and ir_send worked without error.)
+
+
+3. Bridge drivers, if able, should provide a chip reset() callback
+to lirc_zilog via struct IR_i2c_init_data.  cx18 and ivtv already have routines
+to perform Z8 chip resets via GPIO manipulations.  This would allow lirc_zilog
+to bring the chip back to normal when it hangs, in the same places the
+original lirc_pvr150 driver code does.  This is not strictly needed, so it
+is not required to move lirc_zilog out of staging.
+
+Note: Both lirc_zilog and ir-kbd-i2c support the Zilog Z8 for IR, as programmed
+and installed on Hauppauge products.  When working on either module, developers
+must consider at least the following bridge drivers which mention an IR Rx unit
+at address 0x71 (indicative of a Z8):
+
+	ivtv cx18 hdpvr pvrusb2 bt8xx cx88 saa7134

+ * Steve's changes to improve transmission fidelity:
+ *   - for systems with the rdtsc instruction and the clock counter, a
+ *     send_pule that times the pulses directly using the counter.
+ *     This means that the LIRC_SERIAL_TRANSMITTER_LATENCY fudge is
+ *     not needed. Measurement shows very stable waveform, even where
+ *     PCI activity slows the access to the UART, which trips up other
+ *     versions.
+ *   - For other system, non-integer-microsecond pulse/space lengths,
+ *     done using fixed point binary. So, much more accurate carrier
+ *     frequency.
+ *   - fine tuned transmitter latency, taking advantage of fractional
+ *     microseconds in previous change
+ *   - Fixed bug in the way transmitter latency was accounted for by
+ *     tuning the pulse lengths down - the send_pulse routine ignored
+ *     this overhead as it timed the overall pulse length - so the
+ *     pulse frequency was right but overall pulse length was too
+ *     long. Fixed by accounting for latency on each pulse/space
+ *     iteration.

+ * This LIRC driver provides access to the TechnoTrend USB IR Receiver.

+ * isochronous USB packets each of size 128 byte.
+ * Currently the driver reduces the sampling rate by factor of 8 as this

+ * But the driver does not rely on RC-5 it should be able to decode every
+ * IR signal that is not too fast.

+	* Motion detection flags need to be moved to v4l2
+	* Some private CIDs need to be moved to v4l2
+
+TODO (general):
+
+	* encoder on/off controls
+	* mpeg cid bitrate mode (vbr/cbr)
+	* mpeg cid bitrate/bitrate-peak
+	* mpeg encode of user data
+	* mpeg decode of user data
+	* switch between 4 frames/irq to 1 when using mjpeg (and then back
+	  when not)
+	* implement a CID control for motion areas/thresholds
+	* implement CID controls for mozaic areas
+	* allow for higher level of interval (for < 1 fps)
+	* sound:
+	  - implement playback via external sound jack
+	  - implement loopback of external sound jack with incoming audio?
+	  - implement pause/resume
