TEAC Corporation launched IF-FW/DM MkII as an add-in card for TASCAM
DM-3200 and DM-4800. This card uses TC Applied Technologies DICE II
ASIC.

This commit supports the add-in card. The configuration ROM content
includes some quirks:

- The category value stored in chip_ID_hi field of bus information block
  is zero.
- The value of model in unit directory (0x00022e) is different from the
  one in root directory (0x000006).

The hardware allows users to select the total number of audio data channels
available for system from 16 and 32 channels for both input and output
direction. In 16-channel mode,  all audio data are transferred in a
single isochronous packet stream, while in 32-channel mode, they are
transferred across two streams. After the user changes the channel
configuration on the hardware panel, the device temporarily disappears
from the bus and reappears with the new stream formats. During device
probing the ALSA dice driver checks the number of available isochronous
packet streams to determine the active mode of the hardware.

*-objs suffix is reserved rather for (user-space) host programs while
usually *-y suffix is used for kernel drivers (although *-objs works
for that purpose for now).

Let's correct the old usages of *-objs in Makefiles.

<title>ALSA: dice: add stream format parameters for Weiss devices</title>

Hard-coded stream format parameters are added for Weiss Engineering
FireWire devices. When the device vendor and model match, the parameters
are copied into the stream format cache. This allows for setting all
supported sampling rates up to 192kHz, and consequently adjusting the
number of available I/O channels.

<title>ALSA: dice: add support for Focusrite Saffire Pro 40 with TCD3070 ASIC</title>

<link rel='alternate' type='text/html' href='https://git.toradex.cn/cgit/linux-toradex.git/commit/?id=2133dc91d6658242009177b564ac47c49e08668a'/>
<id>2133dc91d6658242009177b564ac47c49e08668a</id>
<content type='text'>
TC Applied Technologies (TCAT) produces TCD3070 as final DICE ASIC for
communication in IEEE 1394 bus for IEC 61883-1/6 protocol. As long as I
know, latter model of Focusrite Saffire Pro 40 is an application of the
ASIC and only in the market for consumers.

This patchset adds support for the device. The device has several
remarkable points.

1. No support for extended synchronization information section in TCAT
general protocol. The value of GLOBAL_EXTENDED_STATUS register is always
zero. Additionally, NOTIFY_EXT_STATUS message is never emitted.

2. No support for TCAT protocol extension. Hard coding is required for
format of CIP payload.

3. During several seconds after changing sampling rate, the block to
process PCM frames is under disfunction. When starting packet streaming
during the state, the block is never function till configuring different
sampling rate and several seconds.

This commit adds support for the device. The item 1 and 2 can be
adaptable, while item 3 is not. It's not preferable that user process
is forced to sleep during the disfunction in the call of ioctl(2) with
SNDRV_PCM_IOCTL_HW_PARAMS or SNDRV_PCM_IOCTL_PREPARE request. It's
inconvenient but let user configure preferable sampling rate in advance
of starting PCM substream.

The content of configuration ROM in the device I used is available at:
 * https://github.com/takaswie/am-config-roms/

I note that any mixer control operation is implemented by unique
transaction. The frame of request consists of 16 bytes header followed
by payload.

header (4 quadlets):
1st: the type of request, prefixed with 0x8000
2nd: counter at 2 bytes in MSB side, the length of data at 2 bytes in LSB
     side
3rd: parameter 0
4th: parameter 1

payload (variable length if need):
5th-: data according to parameters

The request frame is sent by block write request to 0x'ffff'e040'01c0.

The frame of response is similar to the frame of request, but it is
header only, thus fixed to 16 bytes. The response frame is sent to the
address which is registered by lock transaction to 0x'ffff'e040'0008.

If the operation results in batch of data, the 2nd quadlet of header
includes the length of data like request. The data is itself readable
by read block request to 0x'ffff'e040'0030, which includes both
header and payload for data, thus the length to read should be the
length of data plus 16 bytes for header

The actual value of request, parameter 0, parameter 1, and data is
unclear yet.

I-ONIX FW810s was shipped in Lexicon brand of HARMAN International
industries, Inc 2009. The model uses TCD2220 ASIC as its communication
engine. TCAT general protocol is supported, its extension isn't.

This patch adds support for the model with hard-coded stream formats.

ASoC: Updates for v5.3

This is a very big update, mainly thanks to Morimoto-san's refactoring
work and some fairly large new drivers.

 - Lots more work on moving towards a component based framework from
   Morimoto-san.
 - Support for force disconnecting muxes from Jerome Brunet.
 - New drivers for Cirrus Logic CS47L35, CS47L85 and CS47L90, Conexant
   CX2072X, Realtek RT1011 and RT1308.

ASoC: Updates for v5.3

This is a very big update, mainly thanks to Morimoto-san's refactoring
work and some fairly large new drivers.

 - Lots more work on moving towards a component based framework from
   Morimoto-san.
 - Support for force disconnecting muxes from Jerome Brunet.
 - New drivers for Cirrus Logic CS47L35, CS47L85 and CS47L90, Conexant
   CX2072X, Realtek RT1011 and RT1308.

<title>ALSA: dice: add stream format parameters for PreSonus FireStudio</title>

<content type='text'>
FireStudio was launched by PreSonus 2009. This model consists of three
ICs for its packet processing on IEEE 1394 bus:

 - Texus Instruments TSB41AB2 for physical layer of IEEE 1394 bus
 - WaveFront semiconductor, Dice II STD ASIC for link layer of IEEE 1394
   bus and protocol layer
 - Xilinx Spartan XG3S500E FPGA for signal processing

This model don't support TCAT extended application protocol. For such
devices, ALSA dice driver needs to have hard-coded parameters for stream
formats.

This commit adds hard-coded table for this model. As a result, sampling
transfer frequencies of 88.2/96.0 kHz are supported. I note that this
patch can be backported to Linux kernel v4.18 and later.

Mytek manufactures some equipment with DICE-based firewire ports. These
devices contain old versions of DICE firmware which lacks detailed
stream format reporting for all sampling clock modes.

Building upon the recent work by Takashi Sakamoto, hard-coded parameters
are added for the Stereo 192 DSD-DAC. When the device vendor and model
match the coded parameters are copied into the stream format cache.

TC Applied Technologies (TCAT) have added extension to DICE protocol. This
protocol extension is called as Extended Application Protocol, a.k.a. EAP.

In this protocol extension, units get additional 9 address spaces. One of
it is for current configuration. In this address space, a pair of router
and stream formats are exposed per mode of three sampling transmission
frequencies.

This commit adds support the protocol extension for address space of the
current configuration to generate cache of stream formats.
