Melvin Vermeeren 7c1543f6b5 ALSA: dice: add stream format parameters for Mytek devices

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.

Takashi Sakamoto 58579c056c ALSA: dice: use extended protocol to detect available stream formats
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.

Takashi Sakamoto 28b208f600 ALSA: dice: add parameters of stream formats for models produced by Alesis
Alesis shipped some models with DICE ASICs. All of them just support
DICE original protocol and drivers can't retrieve all of available stream
formats without changing status of sampling transmission frequency
actually.

This commit puts some hard-coded parameters for the models. When detecting
the models, the corresponding parameters are copied as cache of stream
formats.

I note that each of pair of iO14/iO26 and MultiMix 8/12/16 has the same
model ID on their configuration ROM. The MultiMix 8/12/16 just support
one mode for sampling transmission frequency and ALSA dice driver already
handles them correctly. The iO14/iO26 support three modes and need
hard-coded parameters. To distinguish these two models, this commit let
the driver to retrieve current stream formats and compare it to known
parameters, then decide it.

Takashi Sakamoto df4833886f ALSA: fireworks/bebob/oxfw/dice: enable to make as built-in
When committed to upstream, these four modules had wrong entries for
Makefile. This forces them to be loadable modules even if they're set
as built-in.

This commit fixes this bug.

Takashi Sakamoto a113ff886b ALSA: dice: Add support for MIDI capture/playback
This commit adds a support for MIDI capture/playback

When MIDI substrams already start streaming and PCM substreams are going to
join at different sampling rate, streams are stopped once. Then sampling rate
is changed and streams are restarted.

Takashi Sakamoto 19af57b46d ALSA: dice: Split hwdep functionality into a file
This commit adds a file and move some codes related to hwdep functionality.

This interface is designed for mixer/control application. By using hwdep
interface, the application can get information about firewire node, can
lock/unlock kernel streaming and can get notification at starting/stopping
kernel streaming.

Additionally, this interface give a way to read Dice notification.

Takashi Sakamoto 6eb6c81eee ALSA: dice: Split stream functionality into a file
This commit adds a file with some helper functions for streaming, and move some
codes into the file with some arrangements.

Well-known CMP is not used to start/stop streams for Dice chipset. It's
achieved by writing to specific address. We call this way as 'enable'.
When devices are 'enabled', streaming starts in registered isochronous channel.
Some helper functions are already implemented in previous commit.

Basically, the stream is compliant to IEC 61883-6, so-called as AMDTP. But Dice
has a specific quirk, so called-as 'Dual Wire'. This quirk is applied at
176.4/192.0kHz. In this mode, each packet includes double number of events than
number in the specification, and stream runs at a half of sampling rate.

There is another quirk at bus reset. Dice chipset handles drivers' request but
don't re-enable streaming. So stream should be stopped.

Takashi Sakamoto 7c2d4c0cf5 ALSA: dice: Split transaction functionality into a file
This commit adds a file with some helper functions for transaction, and move
some codes into the file with some arrangements.

For Dice chipset, well-known FCP or AV/C commands are not used to control
devices. It's achieved by read/write transactions into specific addresses.

Dice's address area is split into 5 areas. Each area has its own role. The
offset for each area can be got by reading head of the address area. By
reading these areas, drivers can get to know device status. By writing these
areas, drivers can change device status.

Dice has a specific mechanism called as 'notification'. When device status is
changed, Dice devices tells the event by sending transaction. This notification
is sent to an address which drivers register in advance. But this causes an
issue to drivers.

To handle the notification, drivers need to allocate its own callback function
to the address region in host controller. This region is exclusive. For the
other applications, drivers must give a mechanism to read the received
notification. For this purpose, Dice driver already implements hwdep interface.

Dice chipset doesn't allow drivers to register several addresses. In this
reason, when this driver is applied to a device, the other drivers should
_not_ try to register its own address to the device.
