[ Upstream commit b2e9e1c8810ee05c95f4d55800b8afae70ab01b4 ]

Duende Classic was produced by Solid State Logic in 2006, as a
first model of Duende DSP series. The following model, Duende Mini
was produced in 2008. They are designed to receive isochronous
packets for PCM frames via IEEE 1394 bus, perform signal processing by
downloaded program, then transfer isochronous packets for converted
PCM frames.

These two models includes the same embedded board, consists of several
ICs below:
 - Texus Instruments Inc, TSB41AB3 for physical layer of IEEE 1394 bus
 - WaveFront semiconductor, DICE II STD ASIC for link/protocol layer
 - Altera MAX 3000A CPLD for programs
 - Analog devices, SHARC ADSP-21363 for signal processing (4 chips)

This commit adds support for the two models to ALSA dice driver. Like
support for the other devices, packet streaming is just available.
Userspace applications should be developed if full features became
available; e.g. program uploader and parameter controller.

<title>ALSA: firewire-motu: use 'version' field of unit directory to identify model</title>

commit 2d012c65a9ca26a0ef87ea0a42f1653dd37155f5 upstream.

Current ALSA firewire-motu driver uses the value of 'model' field
of unit directory in configuration ROM for modalias for MOTU
FireWire models. However, as long as I checked, Pre8 and
828mk3(Hybrid) have the same value for the field (=0x100800).

unit            | version   | model
--------------- | --------- | ----------
828mkII         | 0x000003  | 0x101800
Traveler        | 0x000009  | 0x107800
Pre8            | 0x00000f  | 0x100800 &lt;-
828mk3(FW)      | 0x000015  | 0x106800
AudioExpress    | 0x000033  | 0x104800
828mk3(Hybrid)  | 0x000035  | 0x100800 &lt;-

When updating firmware for MOTU 8pre FireWire from v1.0.0 to v1.0.3,
I got change of the value from 0x100800 to 0x103800. On the other
hand, the value of 'version' field is fixed to 0x00000f. As a quick
glance, the higher 12 bits of the value of 'version' field represent
firmware version, while the lower 12 bits is unknown.

By induction, the value of 'version' field represents actual model.

This commit changes modalias to match the value of 'version' field,
instead of 'model' field. For degug, long name of added sound card
includes hexadecimal value of 'model' field.

<title>ALSA: firewire-motu: fix construction of PCM frame for capture direction</title>

commit f97a0944a72b26a2bece72516294e112a890f98a upstream.

In data blocks of common isochronous packet for MOTU devices, PCM
frames are multiplexed in a shape of '24 bit * 4 Audio Pack', described
in IEC 61883-6. The frames are not aligned to quadlet.

For capture PCM substream, ALSA firewire-motu driver constructs PCM
frames by reading data blocks byte-by-byte. However this operation
includes bug for lower byte of the PCM sample. This brings invalid
content of the PCM samples.

This commit fixes the bug.

<title>ALSA: bebob: use more identical mod_alias for Saffire Pro 10 I/O against Liquid Saffire 56</title>

<content type='text'>
commit 7dc661bd8d3261053b69e4e2d0050cd1ee540fc1 upstream.

ALSA bebob driver has an entry for Focusrite Saffire Pro 10 I/O. The
entry matches vendor_id in root directory and model_id in unit
directory of configuration ROM for IEEE 1394 bus.

On the other hand, configuration ROM of Focusrite Liquid Saffire 56
has the same vendor_id and model_id. This device is an application of
TCAT Dice (TCD2220 a.k.a Dice Jr.) however ALSA bebob driver can be
bound to it randomly instead of ALSA dice driver. At present, drivers
in ALSA firewire stack can not handle this situation appropriately.

This commit uses more identical mod_alias for Focusrite Saffire Pro 10
I/O in ALSA bebob driver.

This commit fixes hard-coded model-id for an unit of Apogee Ensemble with
a correct value. This unit uses DM1500 ASIC produced ArchWave AG (formerly
known as BridgeCo AG).

I note that this model supports three modes in the number of data channels
in tx/rx streams; 8 ch pairs, 10 ch pairs, 18 ch pairs. The mode is
switched by Vendor-dependent AV/C command, like:

$ cd linux-firewire-utils
$ ./firewire-request /dev/fw1 fcp 0x00ff000003dbeb0600000000 (8ch pairs)
$ ./firewire-request /dev/fw1 fcp 0x00ff000003dbeb0601000000 (10ch pairs)
$ ./firewire-request /dev/fw1 fcp 0x00ff000003dbeb0602000000 (18ch pairs)

When switching between different mode, the unit disappears from IEEE 1394
bus, then appears on the bus with different combination of stream formats.
In a mode of 18 ch pairs, available sampling rate is up to 96.0 kHz, else
up to 192.0 kHz.

As a result of investigation for Fireface 800, 'struct snd_ff_spec.regs'
is just for higher address to receive tx asynchronous packets of MIDI
messages, thus it can be simplified.

This commit simplifies it.

<title>ALSA: fireface: add support for packet streaming on Fireface 800</title>

This commit adds a functionality to multiplex PCM frames into isochronous
packets and demultiplex PCM frames from isochronous packets for ALSA PCM
applications.

Fireface 800 voluntarily maintains resources for tx isochronous
communication.  It performs reservation of isochronous channel and
allocation/update of bandwidth in some cases below:
 - at a first request to allocation after bus resets
 - at requests to allocation when further bandwidth is required

When request is grant and the unit is prepared, read data from
0x0000801c0008 represents isochronous channel for tx stream, then
the unit can handle requests to start communication. If driver
send the request without checking the register, the unit takes
panic to continue bus resets. The unit starts transmission of
tx packets after receiving several rx packets from driver.

I note that the unit can process tx/rx packets and generate/record
sound regardless of HOST LED.

The way to maintain isochronous resources on bus is different between
Fireface 400/800.

This commit is a preparation. This commit moves a function to allocate resource to
model-dependent implementation.

Fireface 400/800 use three modes against the number of data channels in
data block for both tx/rx packets.

This commit adds refactoring for it. Some enumerators are added to
represent each of mode and a function is added to calculate the mode
from sampling frequency code (sfc).

<title>ALSA: fireface: share helper function to switch fetching mode</title>

<content type='text'>
Both of Fireface 400/800 have the same register to switch frame fetching
mode regardless of difference of available number of PCM frames in
rx isochronous packet.

This commit moves a helper function from model-dependent implementation.
