[ Upstream commit bf0cd60b7e33cf221fbe1114e4acb2c828b0af0d ]
AV/C deferred transaction was supported at a commit 00a7bb81c20f ("ALSA:
firewire-lib: Add support for deferred transaction") while 'deferrable'
flag can be uninitialized for non-control/notify AV/C transactions.

This commit fixes the bug. The bug has no disadvantage for the non-
control/notify AV/C transactions since the flag has an effect for AV/C
response with INTERIM (0x0f) status which is not used for the transactions
in AV/C general specification.

[ Upstream commit cddcd5472abb7b8a9c37ccbcf0908b79740a01b5 ]
A user reports functional regression for Mackie Onyx 1640i that the device
generates slow sound with ALSA oxfw driver which supports media clock
recovery. Although the device is based on OXFW971 ASIC, it does not
transfer isochronous packet with own event frequency as expected. The
device seems to adjust event frequency according to events in received
isochronous packets in the beginning of packet streaming. This is
unknown quirk.
This commit fixes the regression to turn the recovery off in driver
side. As a result, nominal frequency is used in duplex packet streaming
between device and driver. For stability of sampling rate in events of
transferred isochronous packet, 4,000 isochronous packets are skipped
in the beginning of packet streaming.

In MOTU protocol v2/v3, first two data chunks across 2nd and 3rd data
channels includes message bytes from device. The total size of message
is 48 bits per data block.
The 'data_block_message' tracepoints event produced by ALSA firewire-motu
driver exposes the sequence of messages to userspace in 64 bit storage,
however lower 32 bits are actually available since current implementation
truncates 16 bits in upper of the message as a result of bit shift
operation within 32 bit storage.
This commit fixes the bug by perform the bit shift in 64 bit storage.

Loud Technologies Mackie Onyx 1640i (former model) is identified as
the model which uses OXFW971. The analysis of packet dump shows that
it transfers events in blocking method of IEC 61883-6, however the
default behaviour of ALSA oxfw driver is for non-blocking method.
This commit adds code to detect it assuming that all of loud models
based on OXFW971 have such quirk. It brings no functional change
except for alignment rule of PCM buffer.

Mark of the Unicorn (MOTU) shipped 896HD 2003 as one of models in second
generation of its FireWire series, and already discontinued it. The model
consists of below ICs:
* Texas Instruments TSB41AB2
* Phillips Semiconductors PDI1394L40
* Altera cyclone EP1C3
* Texas Instruments TMS320VC5402
It supports sampling transmission frequency up to 192.0 kHz. The packet
format differs depending on both of sampling transfer frequency and enabling
ADAT channels. The model doesn't support MIDI message transmission.
This commit adds support for it.

OXFW 971 has no function to use the value in syt field of received
isochronous packet for playback timing generation. In kernel prepatch for
v5.14, ALSA OXFW driver got change to send NO_INFO value in the field
instead of actual timing value. The change brings Apogee Duet FireWire to
generate no playback sound, while output meter moves.
As long as I investigate, _any_ value in the syt field takes the device to
generate sound. It's reasonable to think that the device just ignores data
blocks in packet with NO_INFO value in its syt field for audio data
processing.
This commit adds a new flag for the quirk to fix regression.

ALSA bebob driver has duplicated entries for modalias of
'ieee1394:ven00000AACmo00000002sp0000A02Dver00010001' since entries for
two devices below have the same parameters:
* Acoustic Reality eAR Master One, Eroica, Figaro, and Ciaccona
* TerraTec Aureon 7.1 FireWire
I relied on FFADO revision 737 to add the former entry, on the other hand,
the latter is based on message posted by actual user with information of
sysfs node:
* https://sourceforge.net/p/ffado/mailman/ffado-user/thread/5743F969.2080204%40marcobaldo.ch/
It appears that they have OUI of Terratec Electronic GmbH (0x000aac) and
the same model ID, thus suffice to say that they have something common
in their internals.
Although it's not going to make a big difference, this commit arranges
the entries.

A user of FFADO project reported the issue of ToneWeal FW66. As a result,
the device is identified as one of applications of BeBoB solution.
I note that in the report the device returns contradictory result in plug
discovery process for audio subunit. Fortunately ALSA BeBoB driver doesn't
perform it thus it's likely to handle the device without issues.
I receive no reaction to test request for this patch yet, however it would
be worth to add support for it.

is different. MOTU 828 mk3 Hybrid has additional 4 dummy data chunks for
rx packet.

MOTU 896 is a second model in MOTU FireWire series, produced in 2001. This
model consists of three chips:
* Texas Instruments TSB41AB2 (Physical layer for IEEE 1394 bus)
* Philips Semiconductors PDI 1394L21BE (Link layer for IEEE 1394 bus and
packet processing layer)
* QuickLogic QuickRAM QL4016 (Data block processing layer and digital
signal processing)
This commit adds a support for the model, with its unique protocol as
version 1. The features of this protocol are:
* no MIDI support.
* Rx packets have no data chunks for control and status messages.
* Tx packets have 2 bytes for control and status messages in the end of
each data block.
* The most of settings are represented in bit flag in one quadlet address
(0x'ffff'f000'0b14).
* It's selectable to use signal on optical interface, however the device
has no register specific to it. The state has effect just to whether
to exclude differed data chunks.
* The internal multiplexer is not configured by software.
Just after powering on, the device has a quirk to fail handling
transaction. I recommend users to connect the device enough after powering
on.

MOTU 828 is a first model in MOTU FireWire series, produced in 2001. This
model consists of three chips:
* Texas Instruments TSB41AB1 (Physical layer for IEEE 1394 bus)
* Philips Semiconductors 1394L21BE (Link layer for IEEE 1394 bus and

* QuickLogic QuickRAM QL4016 (Data block processing layer and digital

This commit adds a support for this model, with its unique protocol as
version 1. The features of this protocol are:
* no MIDI support.
* Rx packets have no data chunks for control and status messages.
* Tx packets have 2 data chunks for control and status messages in the
end of each data block. The chunks consist of data block counter
(4 byte) and message (2 byte).
* All of settings are represented in bit flag in one quadlet address
(0x'ffff'f000'0b00).
* When optical interface is configured as S/PDIF, signals of the interface
is multiplexed for packets, instead of signals of coaxial interface.
* The internal multiplexer is not configured by software.
I note that the device has a quirk to mute output voluntarily during
receiving batch of packets in the beginning of packet streaming. The
operation to unmute should be done by software enough after the device
shifts the state, however it's not deterministic. Furthermore, just
after switching rate of sampling clock, the device keeps the state longer.
This patch manages to sleep 100 msec before unmute operation, but it may
fail to release the mute in the case that the rate is changed. As a
workaround, users can restart packet streaming at the same rate, or write
to specific register from userspace.

The quirking bit-flags are currently set as contiguous integer enum values
and so currently SND_BEBOB_QUIRK_INITIAL_DISCONTINUOUS_DBC is zero and so
he quirking never getting set or tested correctly for this quirk. Fix this
by setting the quirking constants as shifted bit values.

For Mackie D.2 FireWire option card, 0x00000f is used for the value of
immediate entry for vendor in unit directory. The value comes from report
by FFADO user in below page:
* http://subversion.ffado.org/wiki/AvcModels/MackieD.2.
However, it seems to be wrong. There are two causes; vendor's mistake to
decide value for GUID field in configuration ROM against standard, as
Stefan Richter mentioned in below post:
* https://lore.kernel.org/alsa-devel/1443917823-13516-1-git-send-email-o-takashi@sakamocchi.jp/#t
Another is implementation of libffado. The library doesn't print out the
value from immediate entry for vendor in unit directory. It just print out
the first 6 bytes of GUID as vendor ID.
This commit replaces with correct vendor OUI.

All of drivers in ALSA firewire stack processes two chances to process
isochronous packets in any isochronous context; in software IRQ context
for 1394 OHCI, and in process context of ALSA PCM application.
In the process context, callbacks of .pointer and .ack are utilized. The
callbacks are done by ALSA PCM core under acquiring lock of PCM substream,
In design of ALSA PCM core, call of snd_pcm_period_elapsed() is used for
drivers to awaken user processes from waiting for available frames. The
function voluntarily acquires lock of PCM substream, therefore it is not
called in the process context since it causes dead lock.
As a workaround to avoid the dead lock, all of drivers in ALSA firewire
stack uses workqueue to delegate the call. A variant of
snd_pcm_period_elapsed() without lock acquisition can obsolete the
workqueue.
An extra care is needed for the callback of .pointer since it's called
from snd_pcm_period_elapsed(). The isochronous context in Linux FireWire
subsystem is safe mostly for nested call except in software IRQ context.
