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

target
This commit changes AMDTP domain to run on an IT context of 1394 OHCI as
IRQ target. No hardware interrupt is scheduled for the other isoc
contexts. All of the isoc context are processed in a callback for an isoc
context of IRQ target.
The IRQ target is automatically selected from a list of AMDTP streams,
thus users of AMDTP domain should add an AMDTP stream for IT context
at least.
The reason to select IT context as IRQ target is that the IT context
runs on local 1394 OHCI controller and it can be used as reliable,
constant IRQ generator. On the other hand, IR context can include skip
cycle according to isoc packet transferred by device.

process context callback
The aim of AMDTP domain is to process several isoc context in the same
time. However, current implementation is against this idea because it
flushes each isoc context in the end of processing context callback.
This commit cancels it.

Unlike other format-related DAI parameters, rdai->bit_clk_inv flag
is not properly re-initialized when setting format for new stream
processing. The inversion, if requested, is then applied not to default,
but to a previous value, which leads to SCKP bit in SSICR register being

In IEC 61883-1/6, one isoc packet can transfer events up to the value of
syt interval. This comes from the interval of isoc cycle. As 1394 OHCI
controller can generate hardware IRQ per isoc packet, the interval is
calculated as 125 usec.
In IEC 61883-1/6, two ways of transmission is described; blocking and
non-blocking methods. In blocking method, the sequence of packet includes
'empty' or 'NODATA' packets which include no events. In non-blocking
method, the number of events per packet is variable up to the syt
interval.
This commit uses double of the value of syt interval as minimum available
size of PCM period due to the above protocol design.

Linux driver for 1394 OHCI controller voluntarily flushes isoc context

kicks tasklet for the isoc context. This is inconvenient to process

ALSA IEC 61883-1/6 packet streaming engine controls 1394 OHCI controller
to generate hardware IRQ for fixed number of isochronous packets (=16)
since its first commit.
This commit allow the engine to generate it for variable period according
to the number of event to handle. For outgoing stream, internal
calculator is used to check the accumulated events. For incoming stream,
the number of data block in the packet of stream is used to check the
accumulated events. When it's unavailable, fixed number of packet
roughly calculated in advance is used instead of event counting.

fixed size
The number of packets in packet buffer has been fixed number (=48) since
first commit of ALSA IEC 61883-1/6 packet streaming engine.
This commit allows the engine to use variable number of packets in the
buffer. The size is calculated by a parameter in AMDTP domain structure
surely to store the number of events in the packets of buffer. Although
the value of parameter is expected to come from 'period size' parameter
of PCM substream, at present 48 is still used.

Przemysław Kopa reports that since commit b516ea586d71 ("PCI: Enable
NVIDIA HDA controllers"), the discrete GPU Nvidia GeForce GT 540M on his
2011 Samsung laptop refuses to runtime suspend, resulting in a power
regression and excessive heat.
Rivera Valdez witnesses the same issue with a GeForce GT 525M (GF108M)
of the same era, as does another Arch Linux user named "R0AR" with a
more recent GeForce GTX 1050 Ti (GP107M).
The commit exposes the discrete GPU's HDA controller and all four codecs
on the controller do not set the CLKSTOP and EPSS bits in the Supported
Power States Response. They also do not set the PS-ClkStopOk bit in the
Get Power State Response. hda_codec_runtime_suspend() therefore does
not call snd_hdac_codec_link_down(), which prevents each codec and the
PCI device from runtime suspending.
The same issue is present on some AMD discrete GPUs and we addressed it
by forcing runtime PM despite the bits not being set, see commit
57cb54e53bdd ("ALSA: hda - Force to link down at runtime suspend on
ATI/AMD HDMI").
Do the same for Nvidia HDMI codecs.

In current implementation, when opening a PCM substream, it's needed to
check whether the opposite PCM substream runs. This is to assign
effectual constraints (e.g. sampling rate) to opened PCM substream.
The number of PCM substreams on AMDTP streams in domain is recorded in
own structure. Usage of this count is an alternative of the above check.
This is better because the count is incremented in pcm.hw_params earlier
than pcm.trigger.
This commit replaces the check with the substream count and the value for
the size of PCM period. Unlike the other drivers in ALSA firewire stack,
no MIDI substream is multiplexed into AMDTP stream.
I note that Fireface AMDTP protocol has a quirk that tx stream includes
blank isochronous cycle. The packet for blank cycle is equivalent to
empty or NODATA packet in IEC 61883-6, thus the protocol is similar to
blocking transmission method of IEC 61883-6. On the other hand, rx
stream adopts non-blocking transmission method. Although the difference
of transmission method between tx/rx streams precisely brings different
timing for a certain amount of events due to their different calculation
for data blocks per packet, it's possible to approximate enough amount
of events mostly has the same timing. Actually current ALSA IEC 61883-1/6
engine uses large amount of data blocks for each hardware IRQ
(=16 packets).

substream can decide hardware parameters by restart packet streaming.
Just checking the substream count can brings regression.
Now AMDTP domain structure has a member for the size of PCM period in
PCM substream which starts AMDTP streams in domain. When the value has
zero and the substream count is greater than 1, it means that any MIDI
substream starts AMDTP streams in domain. Usage of the value can resolve

In current implementation, when opening a PCM substream, it's needed to
check whether the opposite PCM substream runs. This is to assign
effectual constraints (e.g. sampling rate) to opened PCM substream.
The number of PCM substreams and MIDI substreams on AMDTP streams in
domain is recorded in own structure. Usage of this count is an
alternative of the above check. This is better because the count is
incremented in pcm.hw_params earlier than pcm.trigger.
This idea has one issue because it's incremented for MIDI substreams as
well. In current implementation, for a case that any MIDI substream run
and a PCM substream is going to start, PCM application to start the PCM
substream can decide hardware parameters by restart packet streaming.
Just checking the substream count can brings regression.
Now AMDTP domain structure has a member for the size of PCM period in
PCM substream which starts AMDTP streams in domain. When the value has
zero and the substream count is greater than 1, it means that any MIDI
substream starts AMDTP streams in domain. Usage of the value can resolve
the above issue.
This commit replaces the check with the substream count and the value for
the size of PCM period.
Dice hardware has a quirk called as 'Dual Wire'. For a case of higher
sampling transmission frequency, this commit performs calculations between
the number of PCM frames and the number of events in AMDTP stream.

This commit is a preparation to share the size of PCM period between
PCM substreams on AMDTP streams in the same domain. At this time,
the size of PCM period in PCM substream which starts AMDTP streams in the
same domain is recorded.

In IEC 61883-6, it's called as 'event' what has presentation time
represented by timestamp in CIP header. Although the ratio of the number
of event against the number of data block is different depending on
event data type represented by the specific field in CIP header, it's
just one in the most cases supported by ALSA IEC 61883-1/6 engine.
In 1394 OHCI specification, applications can schedule hardware IRQ
by configuring descriptor with IRQ flag for packet against each
isochronous cycle. For future commit, I use the hardware IRQ for
isoc IT context to acknowledge the elapse of PCM period for both
playback/capture directions on AMDTP streams in the same domain.
This commit is a preparation for the above idea. This commit adds
a member into AMDTP domain structure to record the number of PCM frames.

On Asus MJ401TA (with Realtek ALC256), the headset mic is connected to
pin 0x19, with default configuration value 0x411111f0 (indicating no
physical connection).
Enable this by quirking the pin. Mic jack detection was also tested and
found to be working.
This enables use of the headset mic on this product.
