Linus Torvalds 102f9d3d45 sound updates for 6.2-rc1
This looks like a relatively calm development cycle; there have been
 only few changes in ALSA and ASoC core sides while we get lots of
 device-specific fixes and updates as usual.  Most of commits are about
 ASoC, including Intel SOF/AVS and many device tree updates.
 
 Below are some highlights:
 
 Core:
 - Improvement in memalloc helper for fallback allocations
 - More cleanups of ASoC DAPM code
 
 ASoC:
 - Factoring out of mapping hw_params onto SoundWire configuration
 - The ever ongoing overhauls of the Intel DSP code continue, including
   support for loading libraries and probes with IPC4 on SOF.
 - Support for more sample formats on JZ4740
 - Lots of device tree conversions and fixups
 - Support for Allwinner D1, a range of AMD and Intel systems, Mediatek
   systems with multiple DMICs, Nuvoton NAU8318, NXP fsl_rpmsg and
   i.MX93, Qualcomm AudioReach Enable, MFC and SAL, RealTek RT1318 and
   Rockchip RK3588
 
 ALSA:
 - Addition of PCM kselftest; still minimalistic but can be extended
   in future
 - Fixes for corner-case XRUNs with USB-audio implicit feedback mode
 - Usual device-specific quirk updates for USB- and HD-audio
 - FireWire DICE updates
 
 Also, this PR also contains a few cross-tree updates:
 - Some OMAP board file updates for removal of relevant OMAP platforms
 - A new I2C API update for I2C probe API adaption
 - A DRM update for the further hdmi-codec updates

Takashi Sakamoto 2133dc91d6 ALSA: dice: add support for Focusrite Saffire Pro 40 with TCD3070 ASIC
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.

For Lexicon I-ONIX FW810S, the call of ioctl(2) with

does not emit NOTIFY_CLOCK_ACCEPTED notification when accepting
GLOBAL_CLOCK_SELECT operation with the same parameters as current ones.

This commit fixes the regression. When receiving no notification, return
-ETIMEDOUT as long as operating for any change.

Takashi Sakamoto 4121f626d0 ALSA: dice: perform sequence replay for media clock recovery
This commit takes ALSA dice driver to perform sequence replay for media
clock recovery.

Unlike the other types of device, DICE-based devices interpret the value
of syt field of CIP header in rx packets as presentation time for audio
playback, thus it's required for driver to compute value for outgoing
packet adequate to the device. It's done by media clock recovery by
handling tx packets.

The device starts packet transmission immediately at operation to
GLOBAL_ENABLE thus on-the-fly mode is not required.

DICE ASICs supports several pairs of isochronous packet streams.
Actually, maximum two pairs of streams are supported by devices.
We have three cases regarding to the number of streams:

1. a pair of streams
2. two tx packet streams and one rx packet streams
3. one tx packet streams and two rx packet streams
4. two pair of streams

The decision of playback timing is slightly different in the four cases.

In the case 1, sequence replay in the pair results in suitable playback
timing.

In the case 2, sequence replay from the first tx packet stream to rx
packet stream results in suitable playback timing.

In the case 3, sequence replay from tx packet stream to all of rx packet
stream results in suitable playback timing. Furthermore, the cycle to
start receiving packets should be the same between all rx packet streams.

In the case 4, sequence replay in each pair results in suitable playback
timing. Furthermore, the cycle to start receiving packets should be the
same between all rx packet streams.

The sequence replay is tested with below models:

* For case 1:
  * TC Electronic Konnekt 24d (DiceII)
  * TC Electronic Konnekt 8 (DiceII)
  * TC Electronic Konnekt Live (DiceII)
  * TC Electronic Impact Twin (DiceII)
  * TC Electronic Digital Konnekt X32 (DiceII)
  * TC Electronic Desktop Konnekt 6 (TCD2220)
  * Solid State Logic Duende Classic (DiceII)
  * Solid State Logic Duende Mini (DiceII)
  * PreSonus FireStudio Project (TCD2210)
  * PreSonus FireStudio Mobile (TCD2210)
  * Lexicon I-ONIX FW810s (TCD2220)
  * Avid Mbox 3 Pro (TCD2220)

* For case 2 (but case 1 depends on sampling transfer frequency):
  * Alesis iO 26 (DiceII)
  * Alesis iO 14 (DiceII)
  * Alesis MultiMix 12 FireWire (DiceII)
  * Focusrite Saffire Pro 26 (TCD2220)

* For case 3 (but case 1 depends on sampling transfer frequency):
  * M-Audio Profire 610 (TCD2220)
  * Loud Technology Mackie Onyx Blackbird (TCD2210)

* For case 4:
  * TC Electronic Studio Konnekt 48 (DiceII + TCD2220)
  * PreSonus FireStudio (DiceII)
  * M-Audio Profire 2626 (TCD2220)
  * Focusrite Liquid Saffire 56 (TCD2220)

Takashi Sakamoto 41319eb56e ALSA: dice: wait just for NOTIFY_CLOCK_ACCEPTED after GLOBAL_CLOCK_SELECT operation
NOTIFY_CLOCK_ACCEPTED notification is always generated as a result of
GLOBAL_CLOCK_SELECT operation, however NOTIFY_LOCK_CHG notification
doesn't, as long as the selected clock is already configured. In the case,
ALSA dice driver waits so long. It's inconvenient for some devices to lock
to the sequence of value in syt field of CIP header in rx packets.

This commit wait just for NOTIFY_CLOCK_ACCEPTED notification by reverting
changes partially done by two commits below:

 * commit fbeac84dbe ("ALSA: dice: old firmware optimization for Dice notification")
 * commit aec045b80d ("ALSA: dice: change notification mask to detect lock status change")

I note that the successful lock to the sequence of value in syt field of
CIP header in rx packets results in NOTIFY_EXT_STATUS notification, then
EXT_STATUS_ARX1_LOCKED bit stands in GLOBAL_EXTENDED_STATUS register.
The notification can occur enough after receiving the batch of rx packets.
When the sequence doesn't include value in syt field of CIP header in rx
packets adequate to the device, the notification occurs again and the bit
is off.

Models in below series start transmission of packet after receiving the
sequence of packets:

 * Digidesign Digi00x family
 * RME Fireface series

Additionally, models in Tascam FireWire series start multiplexing PCM
frames into packets enough after receiving packets. It's required to
transfer packets on-the-fly for the above models according to nominal
sampling transfer frequency before starting sequence replay.

This commit allows drivers to decide whether the engine transfers packet

Takashi Sakamoto f9e5ecdfc2 ALSA: firewire-lib: add replay target to cache sequence of packet
In design of audio and music unit in IEEE 1394 bus, feedback of
effective sampling transfer frequency (STF) is delivered by packets
transferred from device. The devices supported by ALSA firewire stack
are categorized to three groups regarding to it.

 * Group 1:
   * Echo Audio Fireworks board module
   * Oxford Semiconductor OXFW971 ASIC
   * Digidesign Digi00x family
   * Tascam FireWire series
   * RME Fireface series

 * Group 2:
   * BridgeCo. DM1000/DM1100/DM1500 ASICs for BeBoB solution
   * TC Applied Technologies DICE ASICs

 * Group 3:
   * Mark of the Unicord FireWire series

In group 1, the effective STF is determined by the sequence of the number
of events per packet. In group 2, the sequence of presentation timestamp
expressed in syt field of CIP header is interpreted as well. In group 3,
the presentation timestamp is expressed in source packet header (SPH) of
each data block.

I note that some models doesn't take care of effective STF with large
internal buffer. It's reasonable to name it as group 0:

 * Group 0
   * Oxford Semiconductor OXFW970 ASIC

The effective STF is known to be slightly different from nominal STF for
all of devices, and to be different between the devices. Furthermore, the
effective STF is known to be shifted for long-period transmission. This
makes it hard for software to satisfy the effective STF when processing
packets to the device.

The effective STF is deterministic as a result of analyzing the batch of
packet transferred from the device. For the analysis, caching the sequence
of parameter in the packet is required.

This commit adds an option so that AMDTP domain structure takes AMDTP
stream structure to cache the sequence of parameters in packet transferred
from the device. The parameters are offset ticks of syt field against the
cycle to receive the packet and the number of data blocks per packet.

When starting AMDTP domain, tasks in process context yields running CPU
till all of isochronous context get callback, with an assumption that
it's OK to process content of packet.

However several isochronous cycles are skipped to transfer rx packets, or
the content of rx packets are dropped, to manage the timing to start
processing the packets.

This commit changes the timing for tasks in process context to wake up
when processing content of packet is actually ready.

Takashi Sakamoto 791a485f2d ALSA: dice: add support for Alesis MasterControl
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.

Takashi Sakamoto a9f47fcb5e ALSA: dice: loosen stream format check for MIDI conformant data channel
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.

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

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:

This commit allows ALSA dice driver to share PCM buffer size for both
capture and playback PCM substream. When AMDTP domain starts for one
of the PCM substream, buffer size of the PCM substream is stores to
AMDTP domain structure. Some AMDTP streams have already run with the
buffer size when another PCM substream starts, therefore the PCM
substream has a constraint to its buffer 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.

Takashi Sakamoto a8fb224802 ALSA: dice: use the same size of period for PCM substream in AMDTP streams
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.

Takashi Sakamoto 3a9236e972 ALSA: dice: fix wrong packet parameter for Alesis iO26
At higher sampling rate (e.g. 192.0 kHz), Alesis iO26 transfers 4 data
channels per data block in CIP.

Both iO14 and iO26 have the same contents in their configuration ROM.
For this reason, ALSA Dice driver attempts to distinguish them according
to the value of TX0_AUDIO register at probe callback. Although the way is
valid at lower and middle sampling rate, it's lastly invalid at higher
sampling rate because because the two models returns the same value for
read transaction to the register.

In the most cases, users just plug-in the device and ALSA dice driver
detects it. In the case, the device runs at lower sampling rate and
the driver detects expectedly. For this reason, this commit leaves the
way to detect as is.

Takashi Sakamoto e79c3f0c00 ALSA: dice: fix wrong reference count for stream functionality at error path of rawmidi interface
In IEC 61883-6, several types of sampling data can be multiplexed into
payload of common isochronous packet (CIP). For typical audio and music
units, PCM samples and MIDI messages are multiplexed into one packet
streaming.

ALSA dice driver allows applications of rawmidi interface to start
packet streaming for transmission of MIDI messages. However at error
path, the reference count of stream functionality is not operated
correctly. This can brings a bug that packet streaming is not stopped
when all referrers release the count.

This commit fixes the bug.

Takashi Sakamoto d5553026b5 ALSA: dice: update isochronous resources when starting packet streaming after bus-reset
After bus reset, isochronous resource manager releases all of allocated
isochronous resources. The nodes to transfer isochronous packet should
request reallocation of the resources.

However, between the bus-reset and invocation of 'struct fw_driver.update'
handler, ALSA PCM application can detect this situation by XRUN because
the target device cancelled to transmit packets once bus-reset occurs.

Due to the above mechanism, ALSA fireface driver just stops packet
streaming in the update handler, thus pcm.prepare handler should
request the reallocation.

This commit requests the reallocation in pcm.prepare callback when
bus generation is changed.

Takashi Sakamoto 3cd2c2d780 ALSA: dice: reserve/release isochronous resources in pcm.hw_params/hw_free callbacks
Once allocated, isochronous resources are available for packet
streaming, even if the streaming is cancelled. For this reason,
current implementation handles allocation of the resources and
starting packet streaming at the same time. However, this brings
complicated procedure to start packet streaming.

This commit separates the allocation and starting. The allocation is
done in pcm.hw_params callback and available till pcm.hw_free callback.
Even if any XRUN occurs, pcm.prepare callback is done to restart
packet streaming without releasing/allocating the resources.

There are two points to stop packet streaming; in pcm.hw_params and
pcm.prepare callbacks. The former point is a case that packet streaming
is already started for any MIDI substream then packet streaming is
requested with different sampling transfer frequency for any PCM
substream. The latter point is cases of any XRUN or packet queueing
error.

Takashi Sakamoto c4580f2097 ALSA: dice: add stream format parameters for PreSonus FireStudio
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.

Takashi Sakamoto b2e9e1c881 ALSA: dice: add support for Solid State Logic Duende Classic/Mini
Duende Classic was produced by Solid State Logic in 2006, as a
first model of Duende DSP series. The following model, Duende Mini
was produced in 2008. They are designed to receive isochronous
packets for PCM frames via IEEE 1394 bus, perform signal processing by
downloaded program, then transfer isochronous packets for converted
PCM frames.

These two models includes the same embedded board, consists of several
ICs below:
 - Texus Instruments Inc, TSB41AB3 for physical layer of IEEE 1394 bus
 - WaveFront semiconductor, DICE II STD ASIC for link/protocol layer
 - Altera MAX 3000A CPLD for programs
 - Analog devices, SHARC ADSP-21363 for signal processing (4 chips)

This commit adds support for the two models to ALSA dice driver. Like
support for the other devices, packet streaming is just available.
Userspace applications should be developed if full features became
available; e.g. program uploader and parameter controller.
