Actually remove amdtp.[ch], cmp.[ch].
The feature removal was done in 7301c8d3a0
but these files were not removed for some reason.

/* 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 | ...
