Remove two unused pointers from struct cs_dsp_coeff_ctl by taking the
struct list_head out of struct cs_dsp_alg_region. On a x86_64 build
this saves 16 bytes per control.
Each cs_dsp_coeff_ctl instance needs to keep information about the
algorithm region it refers to. This is done by embedding an instance
of struct cs_dsp_alg_region. But cs_dsp_alg_region was also used to
store entries in a list of algorithm regions, and so had a struct
list_head object for that purpose. This list_head object is not used
with the embedded object in struct cs_dsp_alg_region so was just
wasted bytes.
A new struct cs_dsp_alg_region_list_item has been defined for creating
the list of algorithm regions. It contains a struct cs_dsp_alg_region
and a struct list_head.

1. Quirk framework to handle buggy firmware
With SCMI gaining broader adoption across arm64 platforms, it's
increasingly important to address how we consistently manage out-of-spec
SCMI firmware already deployed in the field. This change introduces a
lightweight quirk framework built around static_keys, enabling developers to:
- Define quirks and their match criteria, which can include:
o A list of compatibles ({ comp, comp2, NULL })
o Vendor ID / Sub-Vendor ID
o Firmware implementation version ranges ([Min_Vers, Max_Vers])
Matching proceeds from the most specific (longest match) to the least
specific. NULL entries are treated as wildcards (i.e., match any value).
This flexibility allows matching very specific combinations or just a
general compatible string.
The quirk code blocks/snippets implementing the workaround are placed near
their intended usage and guarded by a static_key that's tied to the quirk.
Once the SCMI core stack is initialized and retrieves platform info via the
base protocol, any matching quirks will have their associated static_keys
enabled.
2. Quirk for Qualcomm X1E platforms
On some Qualcomm X1E platforms, such as the Lenovo ThinkPad T14s, the
SCMI firmware fails to set the FastChannel support bit for PERF_LEVEL_GET,
yet it crashes when the driver attempts to fall back to standard messaging
which is clearly out-of-spec behavior.
To work around this, the new SCMI quirk framework is used to
unconditionally enable FC initialization for this firmware version.
In the future, once the fixed firmware version is identified, an upper
version bound can be added to the quirk match criteria. Alternatively,
matching can be further restricted using a SoC-specific compatible string
if always enabling FC proves problematic elsewhere.
3. Support for NXP i.MX LMM/CPU vendor protocol extensions
The i.MX95 System Manager (SM) implements Logical Machine Management (LMM)
and a CPU protocol to manage Logical Machines (LM) and CPUs (e.g., M7).
These changes integrate the vendor-specific protocol extensions
implementing the LMM and CPU protocols for the i.MX95, facilitating
standardized communication between the operating system and the platform's
firmware, which will be used by remoteproc drivers. The changes also
include the necessary device tree bindings.
4. Miscellaneous cleanups/changes
These mainly include polling support in SCMI raw mode. The cleanups
centralize error logging for SCMI device creation into a single helper
function, consolidate the device matching logic into a single function, and
ensure that devices must have a name for registration—removing support for
unnamed devices when matching drivers and devices for probing. Transport
devices are now excluded from bus matching, and the correct assignment of
the parent device for the arm-scmi platform device is ensured in the
transport drivers.

To allow ACPM clients to simply be children of the ACPM node in DT,
they need to be able to get the ACPM handle based on that ACPM node
directly.
Add an API to allow them to do so, devm_acpm_get_by_node().
At the same time, the previous approach of acquiring the ACPM handle
via a DT phandle is now obsolete and we can remove
devm_acpm_get_by_phandle(), which was there to facilitate that. There
are no existing or anticipated upcoming users of that API, because all
clients should be children of the ACPM node going forward.
Note that no DTs have been merged that use the old approach, so doing
this API change in this driver now will not affect any existing DTs or
client drivers.

Call cs_dsp_mock_xm_header_get_fw_version() to get the firmware version
from the dummy XM header data in cs_dsp_bin_err_test_common_init().
Make the same change to cs_dsp_bin_test_common_init() and remove the
cs_dsp_mock_xm_header_get_fw_version_from_regmap() function.
The code in cs_dsp_test_bin.c was correctly calling
cs_dsp_mock_xm_header_get_fw_version_from_regmap() to fetch the fw version
from a dummy header it wrote to XM registers. However in
cs_dsp_test_bin_error.c the test doesn't stuff a dummy header into XM, it
populates it the normal way using a wmfw file. It should have called
cs_dsp_mock_xm_header_get_fw_version() to get the data from its blob
buffer, but was calling cs_dsp_mock_xm_header_get_fw_version_from_regmap().
As nothing had been written to the registers this returned the value of
uninitialized data.
The only other use of cs_dsp_mock_xm_header_get_fw_version_from_regmap()
was cs_dsp_test_bin.c, but it doesn't need to use it. It already has a
blob buffer containing the dummy XM header so it can use
cs_dsp_mock_xm_header_get_fw_version() to read from that.

The T-Head TH1520 SoC uses an E902 co-processor running Always-On (AON)
firmware to manage power, clock, and other system resources [1]. This
patch introduces a driver implementing the AON firmware protocol,
allowing the Linux kernel to communicate with the firmware via mailbox
channels. Through an RPC-based interface, the kernel can initiate power
state transitions, update resource configurations, and perform other
AON-related tasks.

Alive Clock and Power Manager (ACPM) Message Protocol is defined for
the purpose of communication between the ACPM firmware and masters
(AP, AOC, ...). ACPM firmware operates on the Active Power Management
(APM) module that handles overall power activities.
ACPM and masters regard each other as independent hardware component and
communicate with each other using mailbox messages and shared memory.
This protocol driver provides the interface for all the client drivers
making use of the features offered by the APM. Add ACPM protocol support.

These are changes to SoC specific drivers and DT bindings that don't have
a separate subsystem tree, or that get grouped here for simplicity.
Nothing out of the ordinary for the 6.14 release here:
- Most of the updates are for Qualcomm specific drivers, adding support
for additional SoCs in the exssting drivers, and support for wrapped
encryption key access in the SCM firmware.

"These are changes to SoC specific drivers and DT bindings that don't
have a separate subsystem tree, or that get grouped here for
simplicity.
Nothing out of the ordinary for the 6.14 release here:

support for additional SoCs in the exssting drivers, and support
for wrapped encryption key access in the SCM firmware.

Add helper functions for the SCM calls required to support
hardware-wrapped inline storage encryption keys. These SCM calls manage
wrapped keys via Qualcomm's Hardware Key Manager (HWKM), which can only
be accessed from TrustZone.
QCOM_SCM_ES_GENERATE_ICE_KEY and QCOM_SCM_ES_IMPORT_ICE_KEY create a new
long-term wrapped key, with the former making the hardware generate the
key and the latter importing a raw key. QCOM_SCM_ES_PREPARE_ICE_KEY
converts the key to ephemerally-wrapped form so that it can be used for
inline storage encryption. These are planned to be wired up to new
ioctls via the blk-crypto framework; see the proposed documentation for
the hardware-wrapped keys feature for more information.
Similarly there's also QCOM_SCM_ES_DERIVE_SW_SECRET which derives a
"software secret" from an ephemerally-wrapped key and will be wired up
to the corresponding operation in the blk_crypto_profile.
These will all be used by the ICE driver in drivers/soc/qcom/ice.c.
[EB: merged related patches, fixed error handling, fixed naming, fixed
docs for size parameters, fixed qcom_scm_has_wrapped_key_support(),
improved comments, improved commit message.]

Add a mock regmap implementation to act as a simulated DSP for KUnit
testing. This is built as a utility module so that it could be used by
clients of cs_dsp to create a mock "DSP" for their own testing.
cs_dsp interacts with the DSP only through registers. Most of the
register space of the DSP is RAM. ADSP cores have a small set of control
registers. HALO Core DSPs have a much larger set of control registers but
only a small subset are used.
Most writes are "blind" in the sense that cs_dsp does not expect to
receive any sort of response from the DSP. So there isn't any need to
emulate a "DSP", only a set of registers that can be written and read
back.
The idea of the mock regmap is to use the cache to accumulate writes
which can then be tested against the values that are expected to be in
the registers.
Stray writes can be detected by dropping the cache entries for all
addresses that should have been written and then issuing a regcache_sync().
If this causes bus writes it means there were writes to unexpected
registers.

The QCOM_SCM_SVC_MP service provides QCOM_SCM_MP_CP_SMMU_APERTURE_ID,
which is used to trigger the mapping of register banks into the SMMU
context for per-processes page tables to function (in case this isn't

Refactors the reset handling mechanisms by replacing the reset ID's
enum type with a u32. This update improves flexibility, allowing the
reset ID to accommodate a broader range of values, including those
that may not fit into predefined enum values.
The use of u32 for reset ID enhances extensibility, especially for
hardware platforms or features where more granular control of reset
operations is required. By shifting to a general integer type, this
change reduces constraints and simplifies integration with other
system components that rely on non-enum-based reset IDs.

Add missing PM EEMI APIs interface in debug firmware driver.
The debugfs firmware driver interface is intended for testing and
debugging the EEMI APIs only. This interface does not contain any
checking regarding improper usage, and the number, type and valid
ranges of the arguments. This interface must be used with a lot of
care. In fact, accessing this interface during normal PM operation
will very likely cause unexpected problems.
The debugfs interface shouldn't be used in the production system and
hence it is disabled by default in defconfig.

Qualcomm driver updates for v6.12
Support is added for making SCM driver configure the system either for a
full or minimal ramdump following a system crash. The ramdump mode is
changed from being enable-only to enable/disable as requested.
The QSEECOM uefisecapp interface is allow-listed on Surface Laptop 7 and
Lenovo Thinkpad T14s, providing EFI variable access.
The change to match the SMD RPM driver based on the SMD channel name is
reverted, in favor of stepping back to OF-based matching, as a means to
get module autoloading to work properly.
AOSS, APR, ICE, OCMEM, PBS and SMP2P drivers has error handling cleaned
up using scoped resources.
Trace events are added to the BWMON and SMP2P drivers, for better
insights into their operations.
The X1E LLCC configuration data is updated based on recommended values.
A number of platforms are added to the in-kernel PD-mapper.
SocInfo driver is extended with IDs from SM7325, QCS8275 and QCS8300
families.

- MIDI2 time-base extension in ALSA sequencer API
ASoC:
- Syncing of features between simple-audio-card and the two
audio-graph cards
- Support for specifying the order of operations for components
within cards to allow quirking for unusual systems
- Lots of DT schema conversions
- Continued SOF/Intel updates for topology, SoundWire, IPC3/4

Drop the DMA mapping operations from qcom_scm_qseecom_app_send() and
convert all users of it in the qseecom module to using the TZ allocator
for creating SCM call buffers. As this is largely a module separate from
the SCM driver, let's use a separate memory pool. Set the initial size to
4K and - if we run out - add twice the current amount to the pool.

We have several SCM calls that require passing buffers to the TrustZone
on top of the SMC core which allocates memory for calls that require
more than 4 arguments.
Currently every user does their own thing which leads to code
duplication. Many users call dma_alloc_coherent() for every call which
is terribly unperformant (speed- and size-wise).
Provide a set of library functions for creating and managing pools of
memory which is suitable for sharing with the TrustZone, that is:
page-aligned, contiguous and non-cachable as well as provides a way of
mapping of kernel virtual addresses to physical space.
Make the allocator ready for extending with additional modes of operation
which will allow us to support the SHM bridge safety mechanism once all
users convert.

This one became bigger than usual, not in the total size but rather
containing lots of small changes all over the places. The majority of
changes are about ASoC, especially SOF / Intel stuff, and we see an
interesting work for ASoC DAPM graph visualization, while there are
many other code cleanup and refactoring, too.
Core:
- A deadlock fix at device disconnection
- A new tool dapm-graph for visualising the DAPM state
ASoC:
- Large updates throughout the Intel audio drivers
- Fixes and clarifications for the DAPM documentation
- Cleanups of accessors for driver data, module labelling, and for
constification
- Modernsation and cleanup work in the Mediatek drivers
- Several fixes and features for the DaVinci I2S driver
- New drivers for several AMD and Intel platforms, Nuvoton NAU8325,
Rockchip RK3308 and Texas Instruments PCM6240
HD-audio:
- Cleanup for CONFIG_PM dependencies
- Cirrus HD-audio codec fixes and quirks
Others:
- Series of tree-wide fixes in Makefiles to use *-y
- Additions of missing module descriptions
- Scarlett2 USB mixer enhancements
- A series of legacy emu10k1 fixes and improvements

It turns out that while the QSEECOM APP_SEND command has specific fields
for request and response buffers, uefisecapp expects them both to be in
a single memory region. Failure to adhere to this has (so far) resulted
in either no response being written to the response buffer (causing an
EIO to be emitted down the line), the SCM call to fail with EINVAL
(i.e., directly from TZ/firmware), or the device to be hard-reset.
While this issue can be triggered deterministically, in the current form
it seems to happen rather sporadically (which is why it has gone
unnoticed during earlier testing). This is likely due to the two
kzalloc() calls (for request and response) being directly after each
other. Which means that those likely return consecutive regions most of
the time, especially when not much else is going on in the system.
Fix this by allocating a single memory region for both request and
response buffers, properly aligning both structs inside it. This
unfortunately also means that the qcom_scm_qseecom_app_send() interface
needs to be restructured, as it should no longer map the DMA regions
separately. Therefore, move the responsibility of DMA allocation (or
mapping) to the caller.

It is a common pattern for functions to take and release the DSP
pwr_lock over the cs_dsp calls to read and write firmware controls.
Add wrapper functions to do this sequence so that the calling code can

Some error event IDs for Versal and Versal NET are different.
Both the platforms should access their respective error event
IDs so use sub_family_code to check for platform and check
error IDs for respective platforms. The family code is passed
via platform data to avoid platform detection again.
Platform data is setup when even driver is registered.

As per the current code base, PM_CLOCK_SETRATE and PM_CLOCK_GETRATE
APIs are not supported for the runtime operations. In the case of
ZynqMP returning an error from TF-A when there is any request to
access these APIs and for Versal also it is returning an error like
NO_ACCESS from the firmware. So, just removing the unused code to
avoid the confusion around these APIs.
Also, there is no issue with the backward compatibility as these APIs
were never used since implemented. Hence no need to bump up the
version of the feature check API as well.

Failure to register SGI for firmware event notification is non-fatal error
when feature is not supported by other modules such as Xen and TF-A. Add
_info level log message for such special case.
Also add XST_PM_INVALID_VERSION error code and map it to -EOPNOSUPP Linux
kernel error code. If feature is not supported or EEMI API version is
mismatch, firmware can return XST_PM_INVALID_VERSION = 4 or
XST_PM_NO_FEATURE = 19 error code.

that is being checked to the feature check API so it could be routed to

System-level platform management layer (do_fw_call()) has support for
maximum of 5 arguments as of now (1 EEMI API ID + 4 command arguments).
In order to support new EEMI PM_IOCTL IDs (Secure Read/Write), this
support must be extended to support one additional argument, which
results in a configuration of - 1 EEMI API ID + 5 command arguments.
Update zynqmp_pm_invoke_fn() and do_fw_call() with this new definition
containing variable arguments. As a result, update all the references

This introduces partial support for the Qualcomm Secure Execution
Environment SCM interface, and uses this to implement EFI variable
access on the Windows On Snapdragon devices (for now).
The 32/64-bit calling convention detector of the SCM interface is
updated to not choose 64-bit convention when Linux is 32-bit. The
"extern" specifier is dropped from the interface include file.
The LLCC driver gains support for carrying configuration for multiple
different system/DDR configurations for a given platform, and selecting
between them. Support for Q[DR]U1000 is added to the driver.
All exported symbols are transitioned to EXPORT_SYMBOL_GPL().
The platform_drivers in the Qualcomm SoC are transitioned to the
void-returning remove_new implementation.
The rmtfs memory driver gains support for leaving guard pages around the
used area, to avoid issues if the allocation happens to be placed

Merge tag 'qcom-drivers-for-6.7' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers
Qualcomm driver updates for v6.7
This introduces partial support for the Qualcomm Secure Execution
Environment SCM interface, and uses this to implement EFI variable
access on the Windows On Snapdragon devices (for now).
The 32/64-bit calling convention detector of the SCM interface is
updated to not choose 64-bit convention when Linux is 32-bit. The
"extern" specifier is dropped from the interface include file.
The LLCC driver gains support for carrying configuration for multiple
different system/DDR configurations for a given platform, and selecting
between them. Support for Q[DR]U1000 is added to the driver.
All exported symbols are transitioned to EXPORT_SYMBOL_GPL().
The platform_drivers in the Qualcomm SoC are transitioned to the
void-returning remove_new implementation.
The rmtfs memory driver gains support for leaving guard pages around the
used area, to avoid issues if the allocation happens to be placed
adjacent to another protected memory region.
The socinfo driver gains knowledge about IPQ8174, QCM6490, SM7150P and
various PMICs used together with SM8550.

Add support for SCM calls to Secure OS and the Secure Execution
Environment (SEE) residing in the TrustZone (TZ) via the QSEECOM
interface. This allows communication with Secure/TZ applications, for
example 'uefisecapp' managing access to UEFI variables.
For better separation, make qcom_scm spin up a dedicated child
(platform) device in case QSEECOM support has been detected. The
corresponding driver for this device is then responsible for managing
any QSEECOM clients. Specifically, this driver attempts to automatically
detect known and supported applications, creating a client (auxiliary)
device for each one. The respective client/auxiliary driver is then
responsible for managing and communicating with the application.
While this patch introduces only a very basic interface without the more
advanced features (such as re-entrant and blocking SCM calls and
listeners/callbacks), this is enough to talk to the aforementioned
'uefisecapp'.

1. Following the ARM SMC32 calling convention, the return value
from secure monitor is a 32-bit signed integer. This patch changes
the type of the return value of the function meson_sm_call().
2. Now, when meson_sm_call() returns a 32-bit signed integer, we need
to ensure that this value is not negative. It is important to check
that the return value is not negative in both the meson_sm_call_read()
and meson_sm_call_write() functions.
3. Add a comment explaining why it is necessary to check if the SMC
return value is equal to 0 in the function meson_sm_call_read().
It is not obvious when reading this code.

The main change this time is the introduction of the drivers/genpd
subsystem that gets split out from drivers/soc to keep common
functionality together. Ulf Hansson is taking over maintainership for
these and is sending a separate pull request with the same commits,
but they are in the soc drivers tree to avoid conflicts against other
soc driver patches.
The SCMI driver subsystem gets an update to version 3.2 of the
specification. There are also updates to memory, reset and other firmware
drivers.
On the soc driver side, the updates are mostly cleanups across a number
of Arm platforms. On driver for loongarch adds power management for DT
based systems, another driver is for HiSilicon's Arm server chips with
their HCCS system health interface.
The remaining updates for the most part add support for additional
hardware in existing drivers or contain minor cleanups. Most of these
are for the Qualcomm Snapdragon platform.

Compatible and clock handling in the Qualcomm SCM driver is cleaned up,
together with a couple stylistic cleanups and transition to mark
exported symbols GPL only.
An abstraction for the RPM subsystem is introduced, to make align the
structure of the SMD and GLINK nodes thereof with the structure when a
remoteproc is involved. This is done to facilitate associating
additional entities with the RPM subsystem.
The qmp_send() API is modified to not expose hardware requirements onto
the client drivers, and then further extended to allow command
formatting directly in the API, to facilitate this typical use case.
In the Qualcomm Command DB driver, NUL characters previously included in
identifiers are dropped from the debugfs, to facilitate scripting.
The thresholds of the BWMON driver are simplified to avoid hard coded
starting values.
The OCMEM driver is updated with some cleanups and fixes, and addition
of MSM8226 support.
PMIC_GLINK gains support for retimer switches, safe mode is selected
when the cable is disconnected from altmode and the same is enabled for
SM8550.
An off-by-one string length check is corrected in the QMI encoder
decoder library.
The RPMh tracepoints are extended to include the state of the request,
to provide needed context in the traced events.
The series from Ulf creating a genpd framework is integrated, to
facilitate the other changes to the cpr, rpmpd and rpmhpd driver.
SDX75 support is added to the rpmhpd driver, and the rpmpd driver is
extended with the same sync_state logic found in the rpmhpd driver.
The socinfo driver gains knowledge about SM4450 and SM7125, the IPQ5019
platform is dropped.
Clock handling in the GSBI driver is cleaned up with the use of
devm_clk_get_enabled().
The list of VMIDs defined for the SCM assign memory interface is
extended.

Qualcomm driver updates for v6.6
Compatible and clock handling in the Qualcomm SCM driver is cleaned up,
together with a couple stylistic cleanups and transition to mark
exported symbols GPL only.
An abstraction for the RPM subsystem is introduced, to make align the
structure of the SMD and GLINK nodes thereof with the structure when a
remoteproc is involved. This is done to facilitate associating
additional entities with the RPM subsystem.
The qmp_send() API is modified to not expose hardware requirements onto
the client drivers, and then further extended to allow command
formatting directly in the API, to facilitate this typical use case.
In the Qualcomm Command DB driver, NUL characters previously included in
identifiers are dropped from the debugfs, to facilitate scripting.
The thresholds of the BWMON driver are simplified to avoid hard coded
starting values.
The OCMEM driver is updated with some cleanups and fixes, and addition
of MSM8226 support.
PMIC_GLINK gains support for retimer switches, safe mode is selected
when the cable is disconnected from altmode and the same is enabled for
SM8550.
An off-by-one string length check is corrected in the QMI encoder
decoder library.
The RPMh tracepoints are extended to include the state of the request,
to provide needed context in the traced events.
The series from Ulf creating a genpd framework is integrated, to
facilitate the other changes to the cpr, rpmpd and rpmhpd driver.
SDX75 support is added to the rpmhpd driver, and the rpmpd driver is
extended with the same sync_state logic found in the rpmhpd driver.
The socinfo driver gains knowledge about SM4450 and SM7125, the IPQ5019
platform is dropped.
Clock handling in the GSBI driver is cleaned up with the use of
devm_clk_get_enabled().
The list of VMIDs defined for the SCM assign memory interface is
extended.

Here is the "big" set of char/misc and other driver subsystems for
6.4-rc1.
It's pretty big, but due to the removal of pcmcia drivers, almost breaks
even for number of lines added vs. removed, a nice change.
Included in here are:
- removal of unused PCMCIA drivers (finally!)
- Interconnect driver updates and additions
- Lots of IIO driver updates and additions
- MHI driver updates
- Coresight driver updates
- NVMEM driver updates, which required some OF updates
- W1 driver updates and a new maintainer to manage the subsystem
- FPGA driver updates
- New driver subsystem, CDX, for AMD systems
- lots of other small driver updates and additions
All of these have been in linux-next for a while with no reported
issues.

As usual, there are lots of minor driver changes across SoC platforms
from NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
These usually add support for additional chip variations in existing
drivers, but also add features or bugfixes.
The SCMI firmware subsystem gains a unified raw userspace interface
through debugfs, which can be used for validation purposes.
Newly added drivers include:
- New power management drivers for StarFive JH7110, Allwinner D1 and
Renesas RZ/V2M
- A driver for Qualcomm battery and power supply status
- A SoC device driver for identifying Nuvoton WPCM450 chips

Merge tag 'qcom-drivers-for-6.3-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers
More Qualcomm driver updates for 6.3
The qcom_scm.h file is moved into firmware/qcom, to avoid having any
Qualcomm-specific files directly in include/linux.
Support for PMIC GLINK is introduced, which on newer Qualcomm platforms
provides an interface to the firmware implementing battery management
and USB Type-C handling. Together with the base driver comes the custom
altmode support driver.
SMD RPM gains support for IPQ9574, and socinfo is extended with support
for revision 17 of the information format and soc_id for IPQ5332 and
IPQ8064 are added.
The qcom_stats is changes not to fail when not all parts are
initialized.

In case the tap delay required by Arasan SDHCI is set to 0, the current
embeddedsw firmware unconditionally writes IOU_SLCR SD_ITAPDLY to 0x100
(SD0_ITAPDLYENA=1, SD0_ITAPDLYSEL=0). Previous behavior was to keep the
IOU_SLCR SD_ITAPDLY set to 0x0. There is some sort of difference in the
behavior between SD0_ITAPDLYENA=1/0 with the same SD0_ITAPDLYSEL=0, even
though the behavior should be identical -- zero delay added to rxclk_in
line. The former breaks HS200 training in low temperature conditions.
Write IOU_SLCR SD_ITAPDLY register to 0 using PM_MMIO_WRITE which seem
to allow unrestricted WRITE access (and PM_MMIO_READ which allows read
access) to the entire address space. This way, it is possible to work
around the defect in IOCTL_SET_SD_TAPDELAY design which does not permit
clearing SDx_ITAPDLYENA bit.
Note that the embeddedsw firmware does not permit clearing the SD_ITAPDLY
SD0_ITAPDLYENA bit, this bit can only ever be set by the firmware and it
is often impossible to update the possibly broken firmware.

rproc-virtio device names are now auto generated, to avoid conflicts
between remoteproc instances.
The imx_rproc driver is extended with support for communicating with and
attaching to a running M4 on i.MX8QXP, as well as support for
attaching to the M4 after self-recovering from a crash. Support is
added for i.MX8QM and mailbox channels are reconnected during the
recovery process, in order to avoid data corruption.
The Xilinx Zynqmp firmware interface is extended and support for the
Xilinx R5 RPU is introduced.
Various resources leaks, primarily in error paths, throughout the
Qualcomm drivers are corrected.
Lastly a fix to ensure that pm_relax is invoked even if the remoteproc
instance is stopped between a crash is being reported and the recovery
handler is scheduled.

As diffstat shows, we've had lots of developments in a wide range
at this time; the majority of changes are about ASoC, including
subsystem-wide cleanups, continued SOF / Intel updates and a
bunch of new drivers (as usual), while there have been some
significant (but almost invisible) improvements in ALSA core
side, too. Below are some highlights:
Core:
- Faster lookups of control elements with Xarray; normal user
won't notice, but on the devices with tons of control elements,
it can be visibly faster
- Support for input validation for controls; this will harden
for badly written drivers in general with a slight overhead
- Deferred async signal handling for working around the potential
deadlocks
- Cleanup / refactoring raw MIDI locking code
ASoC:
- Restructing of the set_fmt() callbacks for making things clearer
in situations like CODEC to CODEC links
- Clean up and modernizing the DAI naming scheme setups
- Merge of more of the Intel AVS driver stack, including some
board integrations
- New version 4 mechanism for communication with SOF DSPs
- Suppoort for dynamically selecting the PLL to use at runtime on
i.MX platforms
- Improvements for CODEC to CODEC support in the generic cards
- Support for AMD Jadeite and various machines, AMD RPL, Intel
MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra
MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and

- arch topology and cache info changes that have been reviewed
and discussed a lot.
- potential error path cleanup fixes
- deferred driver probe cleanups
- firmware loader cleanups and tweaks
- documentation updates
- other small things
All of these have been in the linux-next tree for a while with no
reported problems.

Add helpers that can be layered on top of a buffer read from or to be
written to the DSP to faciliate accessing datastructures within the DSP
memory. These functions handle adding the padding bytes for the DSP,
converting to big endian, and packing arbitrary length data.

The code already has a post_stop callback, add a matching pre_stop
callback to the client_ops that is called before execution is stopped.
This callback provides a convenient place for the client code to
communicate with the DSP before it is stopped.
