<title>ALSA: dice: add support for Alesis MasterControl</title>

<content type='text'>
Alesis MasterControl was shipped 2009 and already discontinued. This model
consists of:
 * TSB41AB2 for physical layer of IEEE 1394
 * WaveFront Dice II STD for link layer and protocol implementation
 * FreeScale DSPB56374AE

Although the firmware of this model can respond against read transaction
to address space for TCAT extension protocol, the content is not valid
for protocol extension. This results in sound card without any PCM/MIDI
interfaces.

This commit adds support the model by adding hard-coded stream formats.

<title>ALSA: dice: loosen stream format check for MIDI conformant data channel</title>

<id>a9f47fcb5e25c088b91ed768061b2ab3602f7868</id>
<content type='text'>
ALSA dice driver expects devices to multiplex MIDI messages into first
port of isochronous communication. Actually devices perform for it.
However, check of stream format is invalid for second port of isochronous
communication. As a result, when the device supports two ports for
isochronous communication and the stream format is hard-coded, ALSA
dice driver fails to start packet streaming.

This commit loosens stream format check for MIDI conformant data channel.

At failure of attempt to detect protocol extension, ALSA dice driver
should be fallback to limited functionality. However it's not.

All the PCM ioctl ops of ALSA FireWire drivers do nothing but calling
the default handler.

Now PCM core accepts NULL as the default ioctl ops(*), so let's drop
altogether.

<content type='text'>
Some devices have a quirk to postpone transmission of isoc packet for
several dozen or hundred isoc cycles since configured to transmit.
Furthermore, some devices have a quirk to transmit isoc packet with
discontinued data of its header.

In 1394 OHCI specification, software allows to start isoc context with
certain isoc cycle. Linux firewire subsystem has kernel API to use it
as well.

This commit uses the functionality of 1394 OHCI controller to handle
the quirks. At present, this feature is convenient to ALSA bebob and
fireface driver. As a result, some devices can be safely handled, as
long as I know:
 - MAudio FireWire solo
 - MAudio ProFire Lightbridge
 - MAudio FireWire 410
 - Roland FA-66

Some devices have a quirk to postpone transmission of isoc packet for
several dozen or hundred isoc cycles since configured to transmit.
Furthermore, some devices have a quirk to transmit isoc packet with
discontinued data of its header.

In 1394 OHCI specification, software allows to start isoc context with
certain isoc cycle. Linux firewire subsystem has kernel API to use it
as well.

This commit uses the functionality of 1394 OHCI controller to handle
the quirks. At present, this feature is convenient to ALSA bebob and
fireface driver. As a result, some devices can be safely handled, as
long as I know:
 - MAudio FireWire solo
 - MAudio ProFire Lightbridge
 - MAudio FireWire 410
 - Roland FA-66

An isoc context for AMDTP stream is flushed to queue packet
by a call of pcm.ack. This commit extends this for AMDTP
domain.
