-/* OVERVIEW
- * --------
- *
- * The AMDTP driver is designed to expose the IEEE1394 bus as a
- * regular OSS soundcard, i.e. you can link /dev/dsp to /dev/amdtp and
- * then your favourite MP3 player, game or whatever sound program will
- * output to an IEEE1394 isochronous channel.  The signal destination
- * could be a set of IEEE1394 loudspeakers (if and when such things
- * become available) or an amplifier with IEEE1394 input (like the
- * Sony STR-LSA1).  The driver only handles the actual streaming, some
- * connection management is also required for this to actually work.
- * That is outside the scope of this driver, and furthermore it is not
- * really standardized yet.
- *
- * The Audio and Music Data Tranmission Protocol is available at
- *
- *     http://www.1394ta.org/Download/Technology/Specifications/2001/AM20Final-jf2.pdf
- *
- *
- * TODO
- * ----
- *
- * - We should be able to change input sample format between LE/BE, as
- *   we already shift the bytes around when we construct the iso
- *   packets.
- *
- * - Fix DMA stop after bus reset!
- *
- * - Clean up iso context handling in ohci1394.
- *
- *
- * MAYBE TODO
- * ----------
- *
- * - Receive data for local playback or recording.  Playback requires
- *   soft syncing with the sound card.
- *
- * - Signal processing, i.e. receive packets, do some processing, and
- *   transmit them again using the same packet structure and timestamps
- *   offset by processing time.
- *
- * - Maybe make an ALSA interface, that is, create a file_ops
- *   implementation that recognizes ALSA ioctls and uses defaults for
- *   things that can't be controlled through ALSA (iso channel).
- *
- *   Changes:
- *
- * - Audit copy_from_user in amdtp_write.
- *                           Daniele Bellucci <bellucda@tiscali.it>

-/* The userspace interface for the Audio & Music Data Transmission
- * Protocol driver is really simple. First, open /dev/amdtp, use the
- * ioctl to configure format, rate, dimension and either plug or
- * channel, then start writing samples.
- *
- * The formats supported by the driver are listed below.
- * AMDTP_FORMAT_RAW corresponds to the AM824 raw format, which can
- * carry any number of channels, so use this if you're streaming
- * multichannel audio.  The AMDTP_FORMAT_IEC958_PCM corresponds to the
- * AM824 IEC958 encapsulation without the IEC958 data bit set, using
- * AMDTP_FORMAT_IEC958_AC3 will transmit the samples with the data bit
- * set, suitable for transmitting compressed AC-3 audio.
- *
- * The rate field specifies the transmission rate; supported values
- * are 32000, 44100, 48000, 88200, 96000, 176400 and 192000.
- *
- * The dimension field specifies the dimension of the signal, that is,
- * the number of audio channels.  Only AMDTP_FORMAT_RAW supports
- * settings greater than 2.
- *
- * The mode field specifies which transmission mode to use. The AMDTP
- * specifies two different transmission modes: blocking and
- * non-blocking.  The blocking transmission mode always send a fixed
- * number of samples, typically 8, 16 or 32.  To exactly match the
- * transmission rate, the driver alternates between sending empty and
- * non-empty packets.  In non-blocking mode, the driver transmits as
- * small packets as possible.  For example, for a transmission rate of
- * 44100Hz, the driver should send 5 41/80 samples in every cycle, but
- * this is not possible so instead the driver alternates between
- * sending 5 and 6 samples.
- *
- * The last thing to specify is either the isochronous channel to use
- * or the output plug to connect to.  If you know what channel the
- * destination device will listen on, you can specify the channel
- * directly and use the AMDTP_IOC_CHANNEL ioctl.  However, if the
- * destination device chooses the channel and uses the IEC61883-1 plug
- * mechanism, you can specify an output plug to connect to.  The
- * driver will pick up the channel number from the plug once the
- * destination device locks the output plug control register.  In this
- * case set the plug field and use the AMDTP_IOC_PLUG ioctl.
- *
- * Having configured the interface, the driver now accepts writes of
- * regular 16 bit signed little endian samples, with the channels
- * interleaved.  For example, 4 channels would look like:
- *
- *   | sample 0                                      | sample 1    ...
- *   | ch. 0     | ch. 1     | ch. 2     | ch. 3     | ch. 0     | ...
- *   | lsb | msb | lsb | msb | lsb | msb | lsb | msb | lsb | msb | ...
- *
