6d5a2dda9b ALSA: firewire-motu: add support for MOTU 896 mk3 FireWire and Hybrid
Mark of the Unicorn released 896 mk3 FireWire in 2008 as part of the third
generation of its FireWire series. In 2011, 896 mk3 hybrid was released to
support USB protocol.

It supports sampling transfer frequency up to 192.0 kHz. The packet
format differs depending on both of current sampling transfer frequency
and the type of signal in optical interfaces. The model supports
transmission of PCM frames as well as MIDI messages.

The 896 mk3 FireWire consists of below ICs:

 * Texas Instruments TSB41AB2
 * Xilinx Spartan-3A FPGA, XC3S500E
 * Texas Instruments TMS320C6722
 * Microchip (Atmel) AT91SAM SAM7S256

It supports sampling transfer frequency up to 192.0 kHz. The packet
format differs depending on both of current sampling transfer frequency
and the type of signal in two pairs of optical interfaces. The model
supports transmission of PCM frames, while has no port for MIDi messages.

The model supports command mechanism to configure internal DSP. Hardware
meter information is available in the first 2 chunks of each data block
of tx packet.

This commit adds support for it. The 896 mk3 FireWire is just tested, but
the 896 mk3 Hybrid is not yet.

90b28f3bb8 ALSA: firewire-motu: add message parser for meter information in command DSP model
Some of MOTU models allows software to configure their DSP parameters by
command included in asynchronous transaction. The models multiplex messages
for hardware meters into isochronous packet as well as PCM frames. For
convenience, I call them as 'command DSP' model.

This patch adds message parser for them to gather hardware meter
information.

5b24119e91 ALSA: firewire-motu: fix rx packet format at higher rate for MOTU 828 mk3 Hybrid
I assumed that the combination of packet formats for MOTU 828 mk3 Hybrid
is the same as MOTU 828 mk3 FireWire. However at higher sampling rate, it
is different. MOTU 828 mk3 Hybrid has additional 4 dummy data chunks for
rx packet.

This commit fixes the issue to which I address at a commit f2ac3b8395
("ALSA: firewire-motu: sequence replay for source packet header").

b431f16f16 ALSA: firewire-motu: add support for MOTU 896
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.

d13d6b284d ALSA: firewire-motu: add support for MOTU 828
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
   packet processing layer)
 * QuickLogic QuickRAM QL4016 (Data block processing layer and digital
   signal processing)

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.

bd10737282 ALSA: firewire-motu: code refactoring to handle model specific switch for protocol v2
In MOTU FireWire series, devices which support protocol version 2 have
several types of hardware design to process audio data frames for isoc
packet. Roughly devices are categorized into three groups:
 - 828mkII
 - Traveler/896HD
 - UltraLite/8pre FireWire

Some bit flags in register addressed by 0x'ffff'f000'0b14
includes device-specific effects.

This commit cleanups implementation of protocol v2 in this point.

6af86bdb8a ALSA: firewire-motu: add support for MOTU 4pre
MOTU 4pre was launched in 2012 by MOTU, Inc. This commit allows userspace
applications can transmit and receive PCM frames and MIDI messages for
this model via ALSA PCM interface and RawMidi/Sequencer interfaces.

The device supports MOTU protocol version 3. Unlike the other devices, the
device is simply designed. The size of data block is fixed to 10 quadlets
during available sampling rates (44.1 - 96.0 kHz). Each data block
includes 1 source packet header, 2 data chunks for messages, 8 data chunks
for PCM samples and 2 data chunks for padding to quadlet alignment. The
device has no MIDI, optical, BNC and AES/EBU interfaces.

Like support for the other MOTU devices, the quality of playback sound
is not enough good with periodical noise yet.

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.

61ccc6f6b2 ALSA: firewire: block .remove callback of bus driver till all of ALSA character devices are released
At present, in .remove callback of bus driver just decrease reference
count of device for ALSA card instance. This delegates release of the
device to a process in which the last of ALSA character device is
released.

On the other hand, the other drivers such as for devices on PCIe are
programmed to block .remove callback of bus driver till all of ALSA
character devices are released.

For consistency of behaviour for whole drivers, this probably confuses
users. This commit takes drivers in ALSA firewire stack to imitate the
above behaviour.

366a20d7a7 ALSA: firewire: use managed-resource of fw unit device for private data
At present, private data of each driver in ALSA firewire stack is
allocated/freed by kernel slab allocator for corresponding unit on
IEEE 1394 bus. In this case, resource-managed slab allocator is
available to release memory object automatically just before releasing
device structure for the unit. This idea can prevent runtime from
memory leak due to programming mistakes.

This commit uses the allocator for the private data. These drivers
already use reference counter to maintain lifetime of device structure
for the unit by a pair of fw_unit_get()/fw_unit_put(). The private data
is safely released in a callback of 'struct snd_card.private_free().

6c5e1ac0e1 ALSA: firewire-motu: add support for Motu Traveler
This commit adds support for MOTU Traveler, launched in 2005, discontinued
quite before. As a result, transmission of PCM frame and MIDI messages is
available via ALSA PCM and RawMIDI/Sequencer interfaces.

This model supports sampling transmission frequency up to 192.0 kHz, and
AES/EBU on XLR interface and ADAT on optical interface. Unlike
Motu 828MkII, Windows driver can switch fetching mode for DSP, like
mute/unmute feature.

Although this commit enables high sampling transmission frequency, actual
sound from this model is not good. As long as I tested, it's silence at
176.4 kHz, and it includes hissing noise at 192.0 kHz. In my opinion, as I
reported at 3526ce7f9ba7 ('ALSA: firewire-motu: add MOTU specific protocol
layer'), timestamping on source packet header (SPH) may not still be good
for this model as well.

3a93d082ba ALSA: firewire-motu: add support for MOTU Audio Express
MOTU Audio Express is one of third generation in MOTU FireWire
series, produced in 2011. This model consists of three chips:
 * TI TSB41AB2 (Physical layer for IEEE 1394 bus)
 * Microchip USB3300 (Hi-Speed USB Device with ULPI interface)
 * Xilinx Spartan-3A FPGA, XC3S400A (Link layer for IEEE 1394 bus, packet
   processing and data block processing layer)

This commit adds support for this model. As I expected, it works with
current implementaion of protocol version 3. On the other hand, the unit
has a quirk to request subaction originated by any driver.

5 bits in LSB side of the field has ack code in acknowledge from the unit
(see clause 7.2.2). A list of the code is shown in Table 3-2.

As long as I investigated, in a case of the '-reserved-' acknowledge
message from the unit, the field has 0x10. On the table, this value is
'Reserved for definition by future 1394 standards'. As long as I know,
any specifications of IEEE 1394 has no such extensions, thus the unit is
out of specification. Besides, I note that the unit does not always
acknowledge with the invalid code. I guess this is a bug of firmware. I
confirmed the bug in firmware version 1.04 and this is the latest one.

5992e30034 ALSA: firewire-motu: add support for MOTU 828mk3 (FireWire/Hybrid) as a model with protocol version 3
MOTU 828mk3 (FireWire/Hybrid) is one of third generation in MOTU FireWire
series, produced in 2008/2014. This model consists of three chips for
functionality on IEEE 1394 bus:

 * TI TSB41AB2 (Physical layer for IEEE 1394 bus)
 * Xilinx Spartan-3E FPGA Family (Link layer for IEEE 1394 bus, packet
   processing and data block processing layer)
 * TI TMS320C6722 (Digital signal processing)

This commit adds a support for this model, with its unique protocol as
version 3. This protocol has some additional features to protocol
version 2.

 * Support several optical interfaces.
 * Support a data chunk for return of reverb effect.
 * Have a quirk of tx packets.
 * Support heartbeat asynchronous transaction.

In this protocol, series of transferred packets has some quirks. Below
fields in CIP headers of the packets are out of IEC 61883-1:
 - SID (source node id): always 0x0d
 - DBS (data block size): always 0x04
 - DBC (data block counter): always 0x00
 - EOH (End of header): always 0x00

Below is an actual sample of transferred packets.

quads CIP1       CIP2
520   0x0D040400 0x22FFFFFF
  8   0x0D040400 0x22FFFFFF
520   0x0D040400 0x22FFFFFF
520   0x0D040400 0x22FFFFFF
  8   0x0D040400 0x22FFFFFF

Status of clock is configured by write transactions to 0x'ffff'f000'0b14,
as well as version 2, while meanings of fields are different from the
former protocols. Modes of optical interfaces are configured by write
transactions to 0x'ffff'f000'0c94.

Drivers can register its address to receive heatbeat transactions from the
unit. 0x'ffff'f000'0b0c is for the higher part and 0x'ffff'f000'0b10 is
for the lower part. Nevertheless, this feature is not useless for this
driver and this commit omits it.

Each data block consists of two parts in a point of the number of included
data chunks. In both of 'fixed' and 'differed' parts, the number of
included data blocks are a multiple of 4, thus depending on models there's
some empty data chunks. For example, 828mk3 includes one pair of empty
data chunks in its fixed part. When optical interface is configured to
S/PDIF, 828mk3 includes one pair of empty data chunks in its differed part.
To reduce consumption of CPU cycles with additional conditions/loops, this
commit just exposes these empty chunks to user space as PCM channels.

Additionally, 828mk3 has a non-negligible overhead to change its sampling
transfer frequency. When softwares send asynchronous transaction to
perform it, LED on the unit starts to blink. In a worst case, it continues
blink during several seconds; e.g. 10 seconds. When stopping blinking,
the unit seems to be prepared for the requested sampling transfer
frequency. To wait for the preparation, this commit forces the driver
to call task scheduler and applications sleeps for 4 seconds.

9e796e7d59 ALSA: firewire-motu: add MIDI functionality
In MOTU FireWire series, MIDI messages are multiplexed to isochronous
packets as well as PCM frames, while the way is different from the one
in IEC 61883-6.

MIDI messages are put into a certain position in message chunks. One data
block can includes one byte of the MIDI messages. When data block includes
a MIDI byte, the block has a flag in a certain position of the message
chunk. These positions are unique depending on protocols.

Once a data block includes a MIDI byte, some following data blocks includes
no MIDI bytes. Next MIDI byte appears on a data block corresponding to
next cycle of physical MIDI bus. This seems to avoid buffer overflow caused
by bandwidth differences between IEEE 1394 bus and physical MIDI bus.

This commit adds MIDI functionality to transfer/receive MIDI messages.

dd49b2d1f0 ALSA: firewire-motu: add PCM functionality
This commit adds PCM functionality to transmit/receive PCM samples.

When one of PCM substreams are running or external clock source is
selected, current sampling rate is used. Else, the sampling rate is
changed according to requests from a userspace application.

Available number of samples in a frame of PCM substream is determined at
open(2) to corresponding PCM character device. Later, packet streaming
starts by ioctl(2) with SNDRV_PCM_IOCTL_PREPARE. In theory, between them,
applications can change state of the unit by any write transaction to
change the number. In this case, this driver may fail packet streaming due
to wrong data format.

9b2bb4f2f4 ALSA: firewire-motu: add stream management functionality
This commit adds a functionality to manage packet streaming for MOTU
FireWire series.

The streaming is not controlled by CMP, thus against IEC 61883-1. Write
transaction to certain addresses start/stop packet streaming.

Transactions to 0x'ffff'f000'0b00 results in isochronous channel number for
both directions and starting/stopping transmission of packets. The
isochronous channel number is represented in 6 bit field, thus units can
identify the channels up to 64, as IEEE 1394 bus specification described.

Transactions to 0x'ffff'f000'0b10 results in packet format for both
directions and transmission speed. When each of data block includes fixed
part of data chunks only, corresponding flags stand.

When bus reset occurs, the units continue to transmit packets with
non-contiguous data block counter. This causes discontinuity detection in
packet streaming engine and ALSA PCM applications receives EPIPE from any
I/O operation. In this case, typical applications manage to recover
corresponding PCM substream. This behaviour is kicked much earlier than
callback of bus reset handler by Linux FireWire subsystem, therefore
status of packet streaming is not changed in the handler.

All models of MOTU FireWire series can be controlled by write transaction
to addresses in a range from 0x'ffff'f0000'0b00 to 0x'ffff'f000'0cff.

The models support asynchronous notification. This notification has 32 bit
field data, and is transferred when status of clock changes. Meaning of
the value is not enough clear yet.

Drivers can register its address to receive the notification. Write
transaction to 0x'ffff'f000'0b04 registers higher 16 bits of the address.
Write transaction to 0x'ffff'f0000'0b08 registers the rest of bits. The
address includes node ID, thus it should be registered every time of bus
reset.

59f6482c21 ALSA: firewire-motu: add an abstraction layer for three types of protocols
In an aspect of used protocols to communicate, models of MOTU FireWire
units are categorized to three generations.

This commit adds an abstraction layer of the protocols for features
related to packet streaming functionality. This layer includes 5
operations.

When configuring packet streaming functionality with sampling rate and
sampling transmission frequency, .get_clock_rate and .set_clock_rate are
called with proper arguments. MOTU FireWire series supports up to 192.0kHz.

When checking current source of sampling clock (not clock for packetization
layer), .get_clock_source is used. Enumeration is added to represent the
sources supported by this series. This operation can be used to expose
available sampling rate to user space applications when the unit is
configured to use any input signal as source of clock instead of crystal
clock.

In the protocols, the path between packet processing layer and digital
signal processing layer can be controlled. This looks a functionality to
'mute' the unit. For this feature, .switch_fetching_mode is added. This
can be used to suppress noises every time packet streaming starts/stops.

In a point of the size of data blocks at a certain sampling transmission
frequency, the most units accept several modes. This is due to usage of
optical interfaces. The size differs depending on which modes are
configured to the interfaces; None, S/PDIF and ADAT. Additionally, format
of packet is different depending on protocols. To cache current size of
data blocks and its format, .cache_packet_formats is added. This is used
by PCM functionality, packet streaming functionality and data block
processing layer.
