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.

In 1394 OHCI (rev.1.1), after OUTPUT_LAST* descriptors is processed,
'xferStaus' field is filled with 'ContextControl[0:15]' (see clause 7.1.3).
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.

In protocols of MOTU FireWire series, when transferring MIDI messages,
transmitter set existence flag to one byte on first several quadlets. The
position differs depending on protocols and models, however two cases are
confirmed; in 5th byte and 8th byte from MSB side.
This commit adds a series of specification flag to describe them. When
the existence flag is in the 5th byte, SND_MOTU_SPEC_[R|T]X_MIDI_2ND_Q is
used. Else, another set of the flag is used. Here, '_Q' means quadlet.

In ALSA control interface, applications can execute two types of request
for value of members on each element; ELEM_READ and ELEM_WRITE. In ALSA
control core, these two requests are handled within read lock of a
counting semaphore, therefore several processes can run to execute these
two requests at the same time. This has an issue because ELEM_WRITE
requests have an effect to change state of the target element. Concurrent
access should be controlled for each of ELEM_READ/ELEM_WRITE case.
This commit uses the counting semaphore as write lock for ELEM_WRITE
requests, while use it as read lock for ELEM_READ requests. The state of
a target element is maintained exclusively between ELEM_WRITE/ELEM_READ
operations.
There's a concern. If the counting semaphore is acquired for read lock
in implementations of 'struct snd_kcontrol.put()' in each driver, this
commit shall cause dead lock. As of v4.13-rc5, 'snd-mixer-oss.ko',
'snd-emu10k1.ko' and 'snd-soc-sst-atom-hifi2-platform.ko' includes codes
for read locks, but these are not in a call graph from
'struct snd_kcontrol.put(). Therefore, this commit is safe.
In current implementation, the same solution is applied for the other
operations to element; e.g. ELEM_LOCK and ELEM_UNLOCK. There's another
discussion about an overhead to maintain concurrent access to an element
during operating the other elements on the same card instance, because the
lock primitive is originally implemented to maintain a list of elements on
the card instance. There's a substantial difference between
per-element-list lock and per-element lock.
Here, let me investigate another idea to add per-element lock to maintain
the concurrent accesses with inquiry/change requests to an element. It's
not so frequent for applications to operate members on elements, while
adding a new lock primitive to structure increases memory footprint for
all of element sets somehow. Experimentally, inquiry operation is more
frequent than change operation and usage of counting semaphore for the
inquiry operation brings no blocking to the other inquiry operations. Thus
the overhead is not so critical for usual applications. For the above
reasons, in this commit, the per-element lock is not introduced.

Any control event is queued by a call of snd_ctl_notify(). This function
adds the event to each queue of opened file data corresponding to ALSA
control character devices. This function acquired two types of lock; a
counting semaphore for a list of the opened file data and a spinlock for
card data opened by the file. Typically, this function is called after
acquiring a counting semaphore for a list of elements in the card data.
In current implementation of a handler for ELEM_WRITE request, the
function is called after releasing the semaphore for a list of elements
in the card data. This release is not necessarily needed.
This commit removes the release to call the function within the critical
section so that later commits are simple.

The previously listed SoCs were also incomplete: for instance, tegra124

The ASRC function is for asynchronous MCLK and LRCLK. For RT5663 ASRC
should be enabled to support pcm format with 100fs.
ASRC function will track i2s clock and generate corresponding

commit 4842e98f26 ("ALSA: seq: Fix race at
creating a queue") attempted to fix a race reported by syzkaller. That
fix has been described as follows:
"
When a sequencer queue is created in snd_seq_queue_alloc(),it adds the
new queue element to the public list before referencing it. Thus the
queue might be deleted before the call of snd_seq_queue_use(), and it
results in the use-after-free error, as spotted by syzkaller.
The fix is to reference the queue object at the right time.
"
Even with that fix in place, syzkaller reported a use-after-free error.
It specifically pointed to the last instruction "return q->queue" in
snd_seq_queue_alloc(). The pointer q is being used after kfree() has
been called on it.
It turned out that there is still a small window where a race can
happen. The window opens at
snd_seq_ioctl_create_queue()->snd_seq_queue_alloc()->queue_list_add()
and closes at
snd_seq_ioctl_create_queue()->queueptr()->snd_use_lock_use(). Between
these two calls, a different thread could delete the queue and possibly
re-create a different queue in the same location in queue_list.
This change prevents this situation by calling snd_use_lock_use() from
snd_seq_queue_alloc() prior to calling queue_list_add(). It is then the
caller's responsibility to call snd_use_lock_free(&q->use_lock).

The commit 0181307abc ("ALSA: seq: Reorganize kconfig and build")
rewrote the dependency of each sequencer module in a standard way, but
there was one change applied mistakenly: CONFIG_SND_SEQ_MIDI isn't
enabled properly by CONFIG_SND_RAWMIDI. I seem to have changed the
wrong one instead, CONFIG_SND_SEQ_MIDI_EMUL, which is eventually
reverse-selected by CONFIG_SND_SEQ_MIDI itself. This ended up the
lack of snd-seq-midi module as reported below.
The fix is to put def_tristate properly to CONFIG_SND_SEQ_MIDI instead
of *_MIDI_EMUL entry.

Current snd_soc_pcm_runtime has platform / codec pointers, and we could
use these specific pointer. But these will be replaced to more generic
"component" soon, and will need more generic method to get each
connected component pointer from rtd.
This patch adds new snd_soc_rtdcom_xxx() to connect/disconnect
component to rtd. It means same as previous "platform" / "codec"
pointer style, but more generic.
We can find necessary component pointer from rtd by using component
driver name on snd_soc_rtdcom_lookup().
Here, the reason why it uses "driver name" is that "component name"
was created by fmt_single_name() and difficult to use it from driver.
Driver of course knows its "driver name", thus, using it is more easy.

This patch move the codec reset code from dai ops to codec probe, so
that the codec is not held in reset when headset detection block is
still active.
Without this patch the codec block will be in reset as long as its not
actively used, which means headset events will not be functional if the
codec dai is not actively used. Point to note is that the headset
detection blocks will work in low power when there is no active audio
usecase and switch to micbias source when audio usecase is active.
Existing dapms should put the codec in low power state anyway when there
is no audio usecase.

Each module's dai callback function availability is controlled
by mod->status. For example "always called", "call once".
In .probe/.remove case, it needs to be called always, because
.probe will call xxx_attach() function on .probe, especially
if platform is using MIXer.
For example, below case, MIX0/DVC0/SSI0 needs to be called twice.
playback = <&src0 &ctu02 &mix0 &dvc0 &ssi0>;
playback = <&src2 &ctu03 &mix0 &dvc0 &ssi0>;

But, because of it, PIO mode needed to call free_irq() when removing,
not only DMA mode.
This patch call free_irq() both PIO/DMA. Otherwise, rsnd IRQ handler

In case of SSI0 playback, SSI1 capture, SSI0 might be shared for
clock output if clock master mode.
Current rsnd driver had been assumed that SSI clock contiguous
output which is needed for SSI parent needs SSICR::EN (SSI module
enable) bit.
But, this bit controls data input/output, not for clock.
Clock contiguous output needs SSICR : FORCE, SCKD, SWSD,
and SSIWSR : CONT. Not SSICR : EN.
Because of this wrong assumption, and insufficient control, on current
code, for example, if it starts SSI0(playback) -> SSI1(capture) order,
SSI0 SSICR::EN bit will temporarily be 0.
It causes playback side underrun error. This is bug.
We can reproduce this issue with SSI+SRC (without DVC), and capture
during playback operation.
This patch fixup current (wrong) assumption, and control SSICR::EN bit
correctly.

User-defined element set registers own handler to get callbacks from TLV
ioctl handler. In the handler, execution path bifurcates depending on
requests from user space. At write request, container in given buffer is
registered to the element set, or replaced old TLV data. At the read
request, the registered data is copied to user space. The command request
is not allowed. In current implementation, function of the handler
includes codes for the two cases.
This commit adds two helper functions for these cases so that readers can
easily get the above design.

In a design of ALSA control core, execution path bifurcates depending on
target element. When a set with the target element has a handler, it's
called. Else, registered buffer is copied to user space. These two
operations are apparently different. In current implementation, they're
on the same function with a condition statement. This makes it a bit hard
to understand conditions of each case.
This commit splits codes for these two cases.

At a previous commit, concurrent requests for TLV data are maintained
exclusively between read requests and write/command requests. TLV
callback handlers in each driver has no risk from concurrent access for
reference/change.
In current implementation, 'struct snd_card' has a mutex to control
concurrent accesses to user-defined element sets. This commit obsoletes it.

In ALSA control interface, applications can execute three types of request
for Type-Length-Value (TLV) data to a set of elements; read, write and
command. In ALSA control core, all of the requests are handled within read
lock to a counting semaphore, therefore several processes can run to access
to the data at the same time for any purposes. This has an issue because
write and command requests have side effect to change state of a set of
elements for the TLV data. Concurrent access should be controlled for each
of reference/change case.
This commit uses the counting semaphore as read lock for TLV read requests,
while use it as write lock for TLV write/command requests. The state of a
set of elements for the TLV data is maintained exclusively between read
requests and write/command requests, or between write and command requests.

Any control event is queued by a call of snd_ctl_notify(). This function
adds the event to each queue of opened file data corresponding to ALSA
control character devices. This function acquired two types of lock; a
counting semaphore for a list of the opened file data and a spinlock for
card data opened by the file. Typically, this function is called after
acquiring a counting semaphore for a list of elements in the card data.
In current implementation of TLV request handler, the function is called
after releasing the semaphore for a list of elements in the card data.
This release is not necessarily needed.
This commit removes the release to call the function within the critical
section so that later commits are simple.
