Takashi Sakamoto ecb40fd2c8 ALSA: dice: share PCM buffer size for both direction
This commit allows ALSA dice driver to share PCM buffer size for both
capture and playback PCM substream. When AMDTP domain starts for one
of the PCM substream, buffer size of the PCM substream is stores to
AMDTP domain structure. Some AMDTP streams have already run with the
buffer size when another PCM substream starts, therefore the PCM
substream has a constraint to its buffer size.

Takashi Sakamoto 94c8101a27 ALSA: dice: register the size of PCM period to AMDTP domain
This commit is a preparation to share the size of PCM period between
PCM substreams on AMDTP streams in the same domain. At this time,
the size of PCM period in PCM substream which starts AMDTP streams in the
same domain is recorded.

Takashi Sakamoto e79c3f0c00 ALSA: dice: fix wrong reference count for stream functionality at error path of rawmidi interface
In IEC 61883-6, several types of sampling data can be multiplexed into
payload of common isochronous packet (CIP). For typical audio and music
units, PCM samples and MIDI messages are multiplexed into one packet
streaming.

ALSA dice driver allows applications of rawmidi interface to start
packet streaming for transmission of MIDI messages. However at error
path, the reference count of stream functionality is not operated
correctly. This can brings a bug that packet streaming is not stopped
when all referrers release the count.

This commit fixes the bug.

Takashi Sakamoto 3cd2c2d780 ALSA: dice: reserve/release isochronous resources in pcm.hw_params/hw_free callbacks
Once allocated, isochronous resources are available for packet
streaming, even if the streaming is cancelled. For this reason,
current implementation handles allocation of the resources and
starting packet streaming at the same time. However, this brings
complicated procedure to start packet streaming.

This commit separates the allocation and starting. The allocation is
done in pcm.hw_params callback and available till pcm.hw_free callback.
Even if any XRUN occurs, pcm.prepare callback is done to restart
packet streaming without releasing/allocating the resources.

There are two points to stop packet streaming; in pcm.hw_params and
pcm.prepare callbacks. The former point is a case that packet streaming
is already started for any MIDI substream then packet streaming is
requested with different sampling transfer frequency for any PCM
substream. The latter point is cases of any XRUN or packet queueing
error.

to add.

This commit uses the cache for this purpose.

Takashi Sakamoto fcbe08d469 ALSA: dice: enclose identifiers referred by single function
Some identifiers are referred just by one functions. In this case, they
can be put into the function definition. This brings two merits; readers
can easily follow codes related to the identifiers, developers are free
from name conflict.

This commit moves such identifiers to each function definition.

Takashi Sakamoto 8ae25b760a ALSA: dice: have two sets of isochronous resources/streams
Currently ALSA dice driver handles a pair of isochronous resources for
IEC 61883-1/6 packet streaming. While, according to some documents about
ASICs named as 'Dice', several isochronous streams are available.

Here, I start to describe ASICs produced under 'Dice' name.
 * Dice II (designed by wavefront semiconductor, including TCAT's IP)
   * STD (with limited functionality of DTCP)
   * CP  (with full functionality of DTCP)
 * TCD2210/2210-E (so-called 'Dice Mini')
 * TCD2220/2220-E (so-called 'Dice Jr.')
 * TCD3070-CH (so-called 'Dice III')

Some documents are public and we can see hardware design of them. We can
find some articles about hardware internal register definitions
(not registers exported to IEEE 1394 bus).

* DICE II User Guide
  * http://www.tctechnologies.tc/archive/downloads/dice_ii_user_guide.pdf
    * 6.1 AVS Audio Receivers
      * Table 6.1: AVS Audio Receiver Memory Map
        * ARX1-ARX4
    * 6.2 AVS Audio Transmitters
      * Table 6.2: AVS Audio Transmitter Memory Map
        * ATX1, ATX2
* TCD22xx User Guide

        * ATX1, ATX2
* DICE III
  * http://www.tctechnologies.tc/downloads/TCD3070-CH.pdf
    * Dual stream 63 channel transmitter/receiver

For Dice II and TCD22xx series, maximum 16 data channels are transferred in
an AMDTP packet, while for Dice III, maximum 32 data channels are
transferred.

According to the design of the series of these ASICs, this commit allows
this driver to handle additional set of isochronous resources. For
practical reason, two pair of isochronous resources are added. As of this
commit, this driver still use a pair of the first isochronous resources.

This commit changes the way to add ALSA MIDI ports. This driver read the
number of multiplexed MIDI substreams from hardware register, then adds the
same number of ALSA MIDI ports. This commit is based on my assumption that
the number is fixed at all of supported sampling transfer frequency.

In IEC 61883-6, MIDI messages are transferred in MIDI conformant data
channel. Essentially, packet streaming layer is not responsible for MIDI
functionality.

This commit moves MIDI trigger helper function from the layer to AM824

later commits.

This commit adds a support for MIDI capture/playback

When MIDI substrams already start streaming and PCM substreams are going to
join at different sampling rate, streams are stopped once. Then sampling rate
is changed and streams are restarted.
