Replace direct printk() calls with the appropriate dev_*() logging
APIs.Use dev_err, dev_warn, dev_info, or dev_dbg to reflect the correct
severity level. Pass the canonical struct device pointer so logs
include device context and become traceable to specific hardware
instances.Improve log clarity, make messages filterable by device
and align the driver with kernel logging conventions to aid
debugging and maintenance.

The function SND_SOC_DAPM_AIF_OUT has its third parameter
as stream index. The stream index is numbered from 0 to 3 for
every output interface widget but with same stream name
"HiFi Capture". So, if the stream name is same, the stream
index cannot be different. Also for capture, there is only one
stream "HiFi Capture", so only one stream index. Therefore,
with this patch changed the stream index to 0 for all the output
interface widgets with stream name "HiFi Capture".

Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:
Next installment of the SDCA changes, hopefully the next series after
this should be the full class driver. It is worth noting this series has
a build dependency on a patch working its way through the PM/ACPI tree:
commit ac46f5b6c6 ("ACPICA: Add SoundWire File Table (SWFT) signature")
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git
But we can probably worry about that later, as normally there is a
reasonable amount of review on these SDCA series'.
This series broadly breaks down into 3 chunks, first there are several
changes to remove the assumption that the struct device used for SDCA
purposes represents the SoundWire slave. This is because the SDCA class
driver will be made of an auxiliary driver for each SDCA Function, thus
the SoundWire slave will be on the parent device for each individual
driver. Then there are patches to add support for UMP/FDL. And then
finally since the rest of the HID support is there and UMP was the last
missing part required a small patch to add a function to allow reporting
of HID events from SDCA devices.

Until now, all products with an amplifier supported by the cs35l56 driver
have shipped with Microsoft Windows pre-installed. The factory calibration
of speaker protection has therefore been done using the Windows driver.
However, products that ship with a Linux-based distro must be able to
perform the factory calibration procedure from within the Linux-based
environment. This patch series adds that support.
NOTE: unfortunately this is yet another series that is mainly ASoC but
also needs some changes to the HDA driver, and they have build dependencies
on the ASoC code. I suggest taking this all through Mark's tree and we'll
avoid sending any other commits to the HDA driver until it has all landed
in Takashi's tree.
The TX side of the SPDIF block on the A523 is almost the same the
previous generations, the only difference being that it has separate
module clock inputs for the TX and RX side.
Since this driver currently only supports TX, add support for a
different clock name so that TX and RX clocks can be separated
if RX support is ever added. Then add support for the A523.

The SPDIF hardware block in the A523 SoC has the same layout as the
H616 for the transmitter side. However unlike previous generations,
the hardware block now takes separate module clocks for the TX and RX
sides. This presumably allows the hardware to send and receive audio
streams at different sample rates. The new hardware also gained RX
insertion detection, and some extra information registers.
Add a new compatible for it without any fallbacks.

The SDCA core processes two different struct device's at various times,
usually it is processing the struct device associated with an individual
SDCA Function driver. However, there are times that it is processing the
struct device associated with the actual SoundWire peripheral, usually
the parent of the Function device.
To ensure this distinction remains clear in the code, rename the variable
when handling the actual SoundWire device to sdev.

Add a set of test cases for cs_amp_set_efi_calibration_data().
Broadly there are two type of behavior being tested:
How the EFI is updated:
- Create a new EFI
- Overwrite part of existing content
- Overwrite part of zero-filled preallocated content
- Grow the file to append new content
And how the location within the content is chosen:
- Overwrite a specific array entry
- Overwrite an entry with the same calTarget (silicon ID)
- Overwrite a free entry
- Append after existing data
Plus some cases for error conditions.

Add cs_amp_set_efi_calibration_data() to write an amp calibration
blob to UEFI calibration variable.
The UEFI variable will be updated or created as necessary.
- If a Vendor-specific variable exists it will be updated,
else if the Cirrus variable exists it will be update
else the Cirrus variable will be created.
Some collateral changes are required:
- cs_amp_convert_efi_status() now specifically handles
EFI_WRITE_PROTECTED error.
- cs_amp_get_cal_efi_buffer() can optionally return the name,
guid and attr of the variable it found.
- cs_amp_get_cal_efi_buffer() will update the 'size' field of
the returned data blob if it is zero. The BIOS could have
pre-allocated the UEFI variable as zero-filled

Add a pointer argument to cs_amp_get_efi_variable() to optionally
return the EFI variable attributes.
Originally this function internally consumed the attributes from
efi.get_variable(). The calling code did not use the attributes
so this was a small simplification.
However, when writing to a pre-existing variable we would want to
pass the existing attributes to efi.set_variable(). This patch
deals with the change to return the attribute in preparation for
adding code to update the variable.

Create debugfs files that can be used to perform factory calibration.
During manufacture, the production line must perform a factory calibration
of the amps. This commit adds this functionality via debugfs files.
As this is only needed during manufacture, there is no need for this to be
available in a normal system so a Kconfig item has been added to enable
this. The new Kconfig option is inside a sub-menu because items do not
group and indent if the parent is invisible or there are multiple parent
dependencies. Anyway the sub-menu reduces the clutter.
cs35l56_hda_apply_calibration() has been changed to return an error code
that can be reported back through the debugfs write. The original call to
this function doesn't check the return code because in normal use it
doesn't matter whether this fails - the firmware will default to a safe
calibration for the platform. But tooling using the debugfs files might
want to know if there was an error.

Add core code to support factory calibration. This can be used by both
the ASoC and HDA drivers.
This code consists of implementations of debugfs handlers for three
debugfs files used to start factory calibration and read the results.
This is not a full implementation of debugfs files. There are some
requirements to synchronize with the rest of the amp driver, and the way
this is done is significantly different between ASoC and HDA. Therefore
cs35l56-shared.c provides the main part of the file handlers, but the
files themselves are defined in the ASoC and HDA drivers with suitable
handling before calling into this shared code.
The cal_data file allows the calibration to be read and also for a
previous calibration to be written (for systems where the storage is not
something directly accessible to drivers, such as on filesystems). Code
outside the kernel should treat the content of cal_data as an opaque blob,
so the struct definition is not exported as a user API.

Add helper functions for performing factory calibration.
cs_amp_read_cal_coeffs() reads the results of a calibration into a
struct cirrus_amp_cal_data. The calTime member is also filled in with
the current time (which is defined to be in Windows format).
cs_amp_write_ambient_temp() writes a given temperature value to the
firmware control for ambient temperature.
The cs_amp_cal_target_u64() has been moved into the header file so
that it can be used by the calling code and by KUnit tests.
cs_amp_create_debugfs() creates a debugfs directory to contain
debugfs files related to calibration. This is placed in a directory
in debugfs root, named "cirrus_logic". The purpose of this is to
make it easier for tooling to find the files it needs by keeping
control of the layout under this directory. By contrast the ASoC
debugfs can vary between kernel releases and doesn't have a strictly
stable naming convention. HDA does not have a debugfs directory at all
and enabling the general ALSA debugfs (which is normally disabled) has
other side-effects.

Read the silicon ID from the amp during one-time cs35l56_hw_init()
and store it in struct cs35l56_base, instead of reading it from
registers every time it is needed.
Note that marking it non-volatile without a default in regmap isn't
a suitable alternative because this causes regcache_sync() to always
write the cached value out to the registers. This could trigger a bus
fault interrupt inside the amp, which we want to avoid.
