programming:
DSP side configures the buffer and sets the GEN bit
Host side sets the RUN bit.
In order to follow this flow, a new global message type has been added to
prepare the DSP side of the DMA:
host sends LOAD_LIBRARY_PREPARE with the dma_id
DSP side sets its buffer and sets the GEN bit
Host sets the RUN bit
Host sends LOAD_LIBRARY with dma_id and lib_id
DSP receives the library data.
It is up to the platform code to use the new prepare stage message and how
to handle the reply to it from the firmware, which can indicate that the
message type is not supported/handled.
In this case the kernel should proceed to the LOAD_LIBRARY stage assuming
a single stage library loading:
host sends LOAD_LIBRARY_PREPARE with the dma_id
DSP replies that the message type is not supported/handled
Host acknowledges the return code and sets the RUN bit
Host sends LOAD_LIBRARY with dma_id and lib_id

An alternate solution was suggested earlier using a dedicated topology

The PCI device registers contain a subsystem ID (SSID), that is
separate from the silicon ID. The PCI specification defines it thus:
"They provide a mechanism for board vendors to distiguish their
boards from one another even thought the boards may have the same
PCI controller on them."
This allows the driver for the silicon part to apply board-speficic
settings based on this SSID.
The CS35L56 driver uses this to select the correct firmware file for
the board. The actual ID is part of the PCI register set of the
host audio interface so this set of patches includes extracting the
SSID from the Intel audio controller and passing it to the machine
driver and then to ASoC components. Other PCI audio controllers
will have the same SSID registers, so can use the same mechanism to

For non-SoundWire systems there is no Windows equivalent of the ASoC driver

2. Linux-specific systems.
3. Composite devices where the cs35l56 is not present in ACPI and is

Case 2 can use the firmware-uid property, though the PCI SSID is supported

ASoC: soc-card: Add storage for PCI SSID
Add members to struct snd_soc_card to store the PCI subsystem ID (SSID)
of the soundcard.
The PCI specification provides two registers to store a vendor-specific
SSID that can be read by drivers to uniquely identify a particular
"soundcard". This is defined in the PCI specification to distinguish
products that use the same silicon (and therefore have the same silicon
ID) so that product-specific differences can be applied.
PCI only defines 0xFFFF as an invalid value. 0x0000 is not defined as
invalid. So the usual pattern of zero-filling the struct and then
assuming a zero value unset will not work. A flag is included to
indicate when the SSID information has been filled in.
Unlike DMI information, which has a free-format entirely up to the vendor,
the PCI SSID has a strictly defined format and a registry of vendor IDs.
It is usual in Windows drivers that the SSID is used as the sole identifier
of the specific end-product and the Windows driver contains tables mapping
that to information about the hardware setup, rather than using ACPI
properties.
This SSID is important information for ASoC components that need to apply
hardware-specific configuration on PCI-based systems.
As the SSID is a generic part of the PCI specification and is treated as
identifying the "soundcard", it is reasonable to include this information
in struct snd_soc_card, instead of components inventing their own custom
ways to pass this information around.

The CODEC driver must be extended to support the S32 LE format

SKU, which uses a 48Mhz MCLK, which seems to be too high of a frequency

ASoC: cs35l41: Fix broken shared boost activation
Enabling the active/passive shared boosts requires setting SYNC_EN, but
*not* before receiving the PLL Lock signal.
Due to improper error handling, it was not obvious that waiting for the
completion operation times out and, consequently, the shared boost is
never activated.
Further investigations revealed the signal is triggered while
snd_pcm_start() is executed, right after receiving the
SNDRV_PCM_TRIGGER_START command, which happens long after the
SND_SOC_DAPM_PRE_PMU event handler is invoked as part of
snd_pcm_prepare(). That is where cs35l41_global_enable() is called
from.
Increasing the wait duration doesn't help, as it only causes an
unnecessary delay in the invocation of snd_pcm_start(). Moving the wait
and the subsequent regmap operations to the SNDRV_PCM_TRIGGER_START
callback is not a solution either, since they would be executed in an
IRQ-off atomic context.
Solve the issue by setting the SYNC_EN bit in PWR_CTRL3 register right
after receiving the PLL Lock interrupt.
Additionally, drop the unnecessary writes to PWR_CTRL1 register, part of
the original mdsync_up_seq, which would have toggled GLOBAL_EN with
unwanted consequences on PLL locking behavior.
