Merge tag 'sound-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
"There are a few intensive changes in ALSA core side at this time that
helped with significant code reduction. Meanwhile we keep getting new
stuff, so the total size still grows...

Anyway, the below are some highlights in this development cycle.

ALSA core:

- New helpers to manage page allocations and card object with devres

- Refactoring for memory allocation with wc-pages

- A new PCM hardware flag SNDRV_PCM_INFO_EXPLICIT_SYNC for
controlling the explicit sync of the stream control; it'll be used
for ASoC SOF and non-coherent memory in future

ASoC:

- Lots of cleanups and improvements to the Intel drivers, including
some new systems support

- New support for AMD Vangoh, CUI CMM-4030D-261, Mediatek Mt8195,
Renesas RZ/G2L Mediatek Mt8195, RealTek RT101P, Renesas RZ/G2L,
Rockchip RK3568 S/PDIF

USB-audio:

- Re-organized the quirk handling and a new option quirk_flags

- Fix for a regression in 5.14 code change for JACK

- Quirks for Sony WALKMAN, Digidesign mbox

HD-audio:

- Enhanced support for CS8409 codec

- More consistent shutdown behavior with the runtime PM

- The model option can accept the PCI or codec SSID as an alias

- Quirks for ASUS ROG, HP Spectre x360

Others:

- Lots of code reduction in legacy drivers with devres helpers

- FireWire MOTU 896HD support"

ALSA: firewire-motu: add support for MOTU 896HD

Mark of the Unicorn (MOTU) shipped 896HD 2003 as one of models in second
generation of its FireWire series, and already discontinued it. The model
consists of below ICs:

* Texas Instruments TSB41AB2
* Phillips Semiconductors PDI1394L40
* Altera cyclone EP1C3
* Texas Instruments TMS320VC5402

It supports sampling transmission frequency up to 192.0 kHz. The packet
format differs depending on both of sampling transfer frequency and enabling
ADAT channels. The model doesn't support MIDI message transmission.

This commit adds support for it.

Pull sound updates from Takashi Iwai:
"As the diffstat scatters over the tree, we've got many tree-wide small
changes, but also got quite a few intrusive changes in the core side.
The only ABI-visible core change is the new rawmidi framing mode
support while others are kernel-internal, mostly code refactoring
and/or nice improvements.

Here are some highlights:

Core:
- A new framing access mode for rawmidi to get timestamps
- Cleanup / refactoring of buffer memory management helper code
- Support for automatic negotiation of ASoC DAI formats
- Revival of software suspend for PCM and control core, as a
preliminary work for PCI BAR rescan support

ASoC:
- Accessory detection support for several Qualcomm parts
- Support for IEC958 control with hdmi-codec
- Merging of Tegra machine drivers into a single driver
- Support for AmLogic SM1 TOACODEC, Intel AlderLake-M, several NXP
i.MX8 variants, NXP TFA1 and TDF9897, Rockchip RK817, Qualcomm
Quinary MI2S, Texas Instruments TAS2505

USB-audio:

- Code cleanup / fixes of usx2y driver
- Scarlett2 mixer code fixes and enhancements
- Quirks for Ozone and Denon devices

- A few quirks for HP and ASUS machines
- Display power management fixes

I assumed that the combination of packet formats for MOTU 828 mk3 Hybrid

is different. MOTU 828 mk3 Hybrid has additional 4 dummy data chunks for

ALSA: firewire-motu: add support for MOTU 896

MOTU 896 is a second model in MOTU FireWire series, produced in 2001. This
model consists of three chips:

* Texas Instruments TSB41AB2 (Physical layer for IEEE 1394 bus)
* Philips Semiconductors PDI 1394L21BE (Link layer for IEEE 1394 bus and
packet processing layer)
* QuickLogic QuickRAM QL4016 (Data block processing layer and digital
signal processing)

This commit adds a support for the model, with its unique protocol as
version 1. The features of this protocol are:

* no MIDI support.
* Rx packets have no data chunks for control and status messages.
* Tx packets have 2 bytes for control and status messages in the end of
each data block.
* The most of settings are represented in bit flag in one quadlet address
(0x'ffff'f000'0b14).
* It's selectable to use signal on optical interface, however the device
has no register specific to it. The state has effect just to whether
to exclude differed data chunks.
* The internal multiplexer is not configured by software.

Just after powering on, the device has a quirk to fail handling
transaction. I recommend users to connect the device enough after powering
on.

* QuickLogic QuickRAM QL4016 (Data block processing layer and digital

This commit adds a support for this model, with its unique protocol as
version 1. The features of this protocol are:

* no MIDI support.
* Rx packets have no data chunks for control and status messages.
* Tx packets have 2 data chunks for control and status messages in the
end of each data block. The chunks consist of data block counter
(4 byte) and message (2 byte).
* All of settings are represented in bit flag in one quadlet address
(0x'ffff'f000'0b00).
* When optical interface is configured as S/PDIF, signals of the interface
is multiplexed for packets, instead of signals of coaxial interface.
* The internal multiplexer is not configured by software.

I note that the device has a quirk to mute output voluntarily during
receiving batch of packets in the beginning of packet streaming. The
operation to unmute should be done by software enough after the device
shifts the state, however it's not deterministic. Furthermore, just
after switching rate of sampling clock, the device keeps the state longer.
This patch manages to sleep 100 msec before unmute operation, but it may
fail to release the mute in the case that the rate is changed. As a
workaround, users can restart packet streaming at the same rate, or write
to specific register from userspace.

ALSA: firewire-motu: add support for MOTU 896HD

Mark of the Unicorn (MOTU) shipped 896HD 2003 as one of models in second
generation of its FireWire series, and already discontinued it. The model
consists of below ICs:

* Texas Instruments TSB41AB2
* Phillips Semiconductors PDI1394L40
* Altera cyclone EP1C3
* Texas Instruments TMS320VC5402

It supports sampling transmission frequency up to 192.0 kHz. The packet
format differs depending on both of sampling transfer frequency and enabling
ADAT channels. The model doesn't support MIDI message transmission.

This commit adds support for it.
