7fbd1753b6 ALSA: firewire-lib/fireworks: fix miss detection of received MIDI messages
In IEC 61883-6, 8 MIDI data streams are multiplexed into single
MIDI conformant data channel. The index of stream is calculated by
modulo 8 of the value of data block counter.

In fireworks, the value of data block counter in CIP header has a quirk
with firmware version v5.0.0, v5.7.3 and v5.8.0. This brings ALSA
IEC 61883-1/6 packet streaming engine to miss detection of MIDI
messages.

This commit fixes the miss detection to modify the value of data block
counter for the modulo calculation.

For maintainers, this bug exists since a commit 18f5ed365d ("ALSA:
fireworks/firewire-lib: add support for recent firmware quirk") in Linux
kernel v4.2. There're many changes since the commit.  This fix can be
backported to Linux kernel v4.4 or later. I tagged a base commit to the
backport for your convenience.

Besides, my work for Linux kernel v5.3 brings heavy code refactoring and
some structure members are renamed in 'sound/firewire/amdtp-stream.h'.
The content of this patch brings conflict when merging -rc tree with
this patch and the latest tree. I request maintainers to solve the
conflict to replace 'tx_first_dbc' with 'ctx_data.tx.first_dbc'.

bcb46a0e0e sound fixes for 5.2-rc5
you might feel like a deja vu to receive a bulk of changes at rc5,
 and it happens again; we've got a collection of fixes for ASoC.
 Most of fixes are targeted for the newly merged SOF (Sound Open
 Firmware) stuff and the relevant fixes for Intel platforms.
 
 Other than that, there are a few regression fixes for the recent
 ASoC core changes and HD-audio quirk, as well as a couple of
 FireWire fixes and for other ASoC codecs.

Stanton SCS.1m can transfer isochronous packet with Multi Bit Linear
Audio data channels, therefore it allows software to capture PCM
substream. However, ALSA oxfw driver doesn't.

This commit changes the driver to add one PCM substream for capture
direction.

 One significant one-liner fix is the disablement of the node-power
 saving on Realtek codecs, which may potentially cover annoying bugs
 like the background noises or click noises on many devices.
 
 Other than that, a fix for FireWire bit definitions, and another fix

cc4f8e91c4 ALSA: firewire-lib: use 8 byte header for IR context to get isochronous cycle
In kernel API of Linux FireWire subsystem, handlers of isochronous
receive (IR) context can get context headers as an argument of
callback. When 4 byte header is used, the context header includes
isochronous packet header for each packet. When 8 byte header is
used, it includes isochronous cycle as well.

ALSA IEC 61883-1/6 engine uses 4 byte header, and computes isochronous
cycle from the cycle of interrupt. The usage of 8 byte header can
obsolete the computation.

Furthermore, this change works well for a case that a series of
packet in one interrupt includes skipped isochronous cycle,

This commit uses 8 byte header to handle isochronous cycle.

35033d8cb7 ALSA: firewire-motu: add support MOTU 8pre FireWire
This commit adds support for MOTU 8pre FireWire, which was shipped 2007
and nowadays already discontinued. Userspace applications can transmit
and receive PCM frames and MIDI messages for this model via ALSA PCM
interface and RawMidi/Sequencer interfaces.

Like the other models of MOTU FireWire series, this model has many
quirks in its CIP.

At first, data channels for two pairs of optical interfaces. At lower
sampling transmission frequency, i.e. 44.1 and 48.0 kHz, one pair is
available for ADAT data, thus 8 data chunks are transferred by CIP.
At middle sampling transmission frequency, i.e.  88.2 and 96.0 kHz,
two pairs are available to keep 8 chunks for ADAT data, thus CIP
still includes 8 data chunks.

Apart from data chunks for optical interface, CIP includes fixed number
of data chunks. In tx stream, two chunks for status message, eight
chunks for samples from analog 1-8 input, two chunks for mix-return.
In rx stream, two chunks for control message, two chunks for main 1-2
output, two chunks for phone 1-2 output, two chunks for dummy 1-2.

CIP header in tx stream includes quirks for its dbs and dbc fields.
The value of dbs field is fixed to 0x13, against its actual size.
The value of dbc field is firstly updated to 0x07 from zero, then
it's incremented continuously according to actual number of data h
blocks.

Finally, the model has own bits to disable frame fetch.

This commit uses several options to absorb the above quirks.

2d012c65a9 ALSA: firewire-motu: use 'version' field of unit directory to identify model
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 <-
828mk3(FW)      | 0x000015  | 0x106800
AudioExpress    | 0x000033  | 0x104800
828mk3(Hybrid)  | 0x000035  | 0x100800 <-

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.

f97a0944a7 ALSA: firewire-motu: fix construction of PCM frame for capture direction
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.

7dc661bd8d ALSA: bebob: use more identical mod_alias for Saffire Pro 10 I/O against Liquid Saffire 56
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.

b2e9e1c881 ALSA: dice: add support for Solid State Logic Duende Classic/Mini
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.

d8002539ec ALSA: fireface: comment cleanup about destination address of async transactions for MIDI messages
In Fireface series, registration of higher 4 bytes of destination
address for asynchronous transaction of MIDI messages is done by
a write transaction to model-specific register.

On the other hand, registration of lower 4 bytes of the address is
selectable from 4 options. A register for this registration includes
the other purpose options such as input attenuation. Thus this
driver expects userspace applications to configure the register.

Actual behaviour for the asynchronous transaction is different
depending on protocols. In former protocol, destination offset
of each transaction is the same as the registered address even if
it is block request. In latter models, destination offset of each
transaction is the offset of previous transaction plus 4 byte
and the transaction is quadlet request.

This commit cleanups comments about the above mechanism.

f0f9f497d4 ALSA: fireface: support rx MIDI functionality for Fireface UCX
In latter model of Fireface series, asynchronous transaction includes
a prefix byte to indicate the way to decode included MIDI bytes.

Upper 4 bits of the prefix byte indicates port number, and the rest 4
bits indicate the way to decode rest of bytes for MIDI messages.

Basically the rest bits indicates the number of bytes for MIDI message.
However, if the last byte of each MIDi message is included, the rest
bits are 0xf. For example:

message: f0 00 00 66 14 20 00 00 f7
offset: content (big endian, port 0)
 '0030: 0x02f00000
 '0030: 0x03006614
 '0030: 0x03200000
 '0030: 0x0ff70000

This commit supports encoding scheme for the above and allows
applications to transfer MIDI messages via ALSA rawmidi interface.
An unused member (running_status) is reused to keep state of
transmission of system exclusive messages.

For your information, this is a dump of config rom.

73f5537fb2 ALSA: fireface: support tx MIDI functionality of Fireface UCX
Fireface UCX transfers asynchronous transactions for MIDI messages.
One transaction includes quadlet data therefore it can transfer 3
message bytes as maximum. Base address of the destination is
configured by two settings; a register for higher 8 byte of the
address, and a bitflag to option register indicates lower 8byte.

The register for higher address is 0x'ffff'0000'0034. Unfortunately,
firmware v24 includes a bug to ignore registered value for the
destination address and transfers to 0x0001xxxxxxxx always. This
driver doesn't work well if the bug exists, therefore users should
install the latest firmware (v27).

The bitflag is a part of value to be written to option register
(0x'ffff'0000'0014).

lower addr:  bitflag (little endian)
 '0000'0000: 0x00002000
 '0000'0080: 0x00004000
 '0000'0100: 0x00008000
 '0000'0180: 0x00010000

This register includes more options but they are not relevant to
packet streaming or MIDI functionality. This driver don't touch it.

Furthermore, the transaction is sent to address offset incremented
by 4 byte to the offset in previous time. When it reaches base address
plus 0x7c, next offset is the base address.

Content of the transaction includes a prefix byte. Upper 4 bits of
the byte indicates port number, and the rest 4 bits indicate the way
to decode rest of bytes for MIDI message.

Except for system exclusive messages, the rest bits are the same as
status bits of the message without channel bits. For system exclusive
messages, the rest bits are encoded according to included message bytes.
For example:

message: f0 7e 7f 09 01 f7
offset: content (little endian, port 0)
 '0000: 0x04f07e7f
 '0004: 0x070901f7

message: f0 00 00 66 14 20 00 00 00 f7
offset: content (little endian, port 1)
 '0014: 0x14f00000
 '0018: 0x14661420
 '001c: 0x14000000
 '0020: 0x15f70000

message: f0 00 00 66 14 20 00 00 f7
offset: content (little endian, port 0)
 '0078: 0x04f00000
 '007c: 0x04661420
 '0000: 0x070000f7

This commit supports decoding scheme for the above and allows
applications to receive MIDI messages via ALSA rawmidi interface.
The lower 8 bytes of destination address is fixed to 0x'0000'0000,
thus this driver expects userspace applications to configure option
register with bitflag 0x00002000 in advance.

900896771a ALSA: fireface: add model-dependent parameter for address range to receive async transaction
In Fireface series, drivers can register destination address for
asynchronous transaction which transfers MIDI messages from device.

In former models, all of the transactions arrive at the registered
address without any offset. In latter models, each of the transaction
arrives at the registered address with sequential offset within 0x00
to 0x7f. This seems to be for discontinuity detection.

This commit adds model-dependent member for the address range.

In a series of Fireface, devices transfer asynchronous transaction with
MIDI messages. In the transaction, content is different depending on
models. ALSA fireface driver has protocol-dependent handler to pick up
MIDI messages from the content.

In latter models of the series, the transaction is transferred to range
of address sequentially. This seems to check continuity of transferred
messages.

address for received transactions.

644b2e9740 ALSA: bebob: fix model-id of unit for Apogee Ensemble
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.

fc716397a5 ALSA: fireface: add support for packet streaming on Fireface 800
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.

a91f676074 ALSA: fireface: add support for Fireface 800 with MIDI functionality only
Fireface 800 is a flagship model of RME GmbH for audio and music units
on IEEE 1394 bus, shipped 2004. This model consists of four chips:
 - TI TSB81BA3D for physical layer on cable environment of EEE 1394 bus
 - TI TSB82AA2 for link layer for 1394 OHCI bus bridge to PCI bus
 - Xilinx Spartan-3 FPGA XC3S400
 - Xilinx High-Performance CPLD XC9572XL

This commit adds support Fireface 800. In this time, the support is
restricted to its MIDI functionality, thus this commit adds some
condition statements to avoid touching streaming functionality.

Unlike Fireface 400, Fireface 800 has no functionality to suppress
asynchronous transactions for MIDI messages except for unregister of
listen address in controller side, thus the feature is available as is.
