The boot-hartid can be a 64bit value on RV64 platforms but
the "boot-hartid" in DT is assumed to be 32bit only.
Detect the size of the "boot-hartid" in DT and use 32bit or 64bit
read appropriately.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"As the 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
WAS883x, and Texas Instruments TAS2780

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.

Introduce a new SMC command INTEL_SIP_SMC_FUNCID_SERVICE_COMPLETED
that polls if a previous asynchronous command was completed. This
SMC command is used by the new FPGA Crypto Service (FCS).
A basic example is that the FCS sends an AES data encryption
call to the secure device manager(SDM) and waits for the completion
of the operation by continuously polling the results with the new
command.

Move the fiddly bits of the efivar layer into its only remaining user,
efivarfs, and confine its use to that particular module. All other uses
of the EFI variable store have no need for this additional layer of
complexity, given that they either only read variables, or read and
write variables into a separate GUIDed namespace, and cannot be used to
manipulate EFI variables that are covered by the EFI spec and/or affect
the boot flow.

Switch the caching linked-list efivars layer implementation to the newly

Commit 5d9db883761a ("efi: Add support for a UEFI variable filesystem")
dated Oct 5, 2012, introduced a new efivarfs pseudo-filesystem to
replace the efivars sysfs interface that was used up to that point to
expose EFI variables to user space.
The main problem with the sysfs interface was that it only supported up
to 1024 bytes of payload per file, whereas the underlying variables
themselves are only bounded by a platform specific per-variable and
global limit that is typically much higher than 1024 bytes.
The deprecated sysfs interface is only enabled on x86 and Itanium, other
EFI enabled architectures only support the efivarfs pseudo-filesystem.
So let's finally rip off the band aid, and drop the old interface
entirely. This will make it easier to refactor and clean up the
underlying infrastructure that is shared between efivars, efivarfs and
efi-pstore, and is long overdue for a makeover.

__efivar_entry_iter() uses a list iterator in a dubious way, i.e., it
assumes that the iteration variable always points to an object of the
appropriate type, even if the list traversal exhausts the list
completely, in which case it will point somewhere in the vicinity of the
list's anchor instead.
Fortunately, we no longer use this function so we can just get rid of it
entirely.

Both efivars and efivarfs uses __efivar_entry_iter() to go over the
linked list that shadows the list of EFI variables held by the firmware,
but fail to call the begin/end helpers that are documented as a
prerequisite.
So switch to the proper version, which is efivar_entry_iter(). Given
that in both cases, efivar_entry_remove() is invoked with the lock held
already, don't take the lock there anymore.

Avoid the efivars layer and simply call the newly introduced EFI
varstore helpers instead. This simplifies the code substantially, and
also allows us to remove some hacks in the shared efivars layer that
were added for efi-pstore specifically.
In order to be able to delete the EFI variable associated with a record,
store the UTF-16 name of the variable in the pstore record's priv field.
That way, we don't have to make guesses regarding which variable the
record may have been loaded from.

The current efivars layer is a jumble of list iterators, shadow data
structures and safe variable manipulation helpers that really belong in
the efivarfs pseudo file system once the obsolete sysfs access method to
EFI variables is removed.
So split off a minimal efivar get/set variable API that reuses the
existing efivars_lock semaphore to mediate access to the various runtime
services, primarily to ensure that performing a SetVariable() on one CPU
while another is calling GetNextVariable() in a loop to enumerate the
contents of the EFI variable store does not result in surprises.

Even though the efivars_lock lock is documented as protecting the
efivars->ops pointer (among other things), efivar_init() happily
releases and reacquires the lock for every EFI variable that it
enumerates. This used to be needed because the lock was originally a
spinlock, which prevented the callback that is invoked for every
variable from being able to sleep. However, releasing the lock could
potentially invalidate the ops pointer, but more importantly, it might
allow a SetVariable() runtime service call to take place concurrently,
and the UEFI spec does not define how this affects an enumeration that
is running in parallel using the GetNextVariable() runtime service,
which is what efivar_init() uses.
In the meantime, the lock has been converted into a semaphore, and the
only reason we need to drop the lock is because the efivarfs pseudo
filesystem driver will otherwise deadlock when it invokes the efivars
API from the callback to create the efivar_entry items and insert them
into the linked list. (EFI pstore is affected in a similar way)
So let's switch to helpers that can be used while the lock is already
taken. This way, we can hold on to the lock throughout the enumeration.

Avoid abusing the efivar API by passing locally instantiated
efivar_entry structs into efivar_set_entry_safe(), rather than using the
API as intended. Instead, just call efi.set_variable() directly.

The efivars intermediate variable access layer provides an abstraction
that permits the EFI variable store to be replaced by something else
that implements a compatible interface, and caches all variables in the
variable store for fast access via the efivarfs pseudo-filesystem.
The SSDT override feature does not take advantage of either feature, as
it is only used when the generic EFI implementation of efivars is used,
and it traverses all variables only once to find the ones it is
interested in, and frees all data structures that the efivars layer
keeps right after.
So in this case, let's just call EFI's code directly, using the function
pointers in struct efi.

Commit b05b9f5f9dcf ("x86, mirror: x86 enabling - find mirrored memory
ranges") introduce the efi_find_mirror() function on x86. In order to reuse
the API we make it public.
Arm64 can support mirrored memory too, so function efi_find_mirror() is added to
efi_init() to this support for arm64.
Since efi_init() is shared by ARM, arm64 and riscv, this patch will bring
mirror memory support for these architectures, but this support is only tested
in arm64.

In SCMI v3.1 the power scale can be in micro-Watts. The upper layers, e.g.
cpufreq and EM should handle received power values properly (upscale when
needed). Thus, provide an interface which allows to check what is the
scale for power values. The old interface allowed to distinguish between
bogo-Watts and milli-Watts only (which was good for older SCMI spec).

Qualcomm driver updates for v5.20
This introduces a new driver that requests interconnect bandwidth based
on throughput measurements of the bwmon hardware blocks found associated
with, among other things, the CPU subsystem on many Qualcomm platforms.
It introduces support for the SCM wrapper driver to vote for
interconnect bandwidth for operations that needs bandwidth to the crypto
engine. This ensures both performance and guards against issues caused
by lacking votes for this path.
The socinfo driver gains knowledge about the SC7180P SoC.
It contains a range of fixes for spelling mistakes, refcount leaks in
various drivers and removes some redundant code from the apr remove
path.
The SCM DT bindings are updated to declare support for QCS404, SM6125
and SDX65.
The command db driver has a strncpy() converted to strscpy_pad() and
then back again with proper documentation to why this was the right API.

If an error occurs, debugfs_create_file() will return ERR_PTR(-ERROR),
so use IS_ERR() to check it.

Use memcpy_toio and memcpy_fromio variants of memcpy to guarantee no
unaligned access to IPC memory area. This is to allow the IPC memory to
be mapped as Device memory to further suppress speculative reads from
happening within the 64 kB memory area above the IPC memory when 64 kB
memory pages are used.

Arm SCMI updates for v5.20
The main additions this time around are:
1. The capability to trace full SCMI message headers and payloads.
The recent unearthing of chain of old firmware issues motivated
this effort so that it is easier to trace them and debug quicker
than it took this time around in absence of such tracing.
2. SCMI System power control driver to handle platform's requests for a
graceful shutdown. Though the system power control protocol has been
around since the begining of SCMI, it lacked the timeout information
that was added in SCMI v3.1 that enables kernel to take appropriate
action within the timeout and doesn't have to rely on any other
user inputs(which was blocking factor for addition of this driver
earlier)
3. Support for SCMI Power Capping protocol that was introduced in SCMI v3.1
This protocol is intended for controlling and monitoring the power
consumption of power capping domains. The firmware also provides the
hierarchy of powercap domains by providing parent domain information.
It also contains a bug fix in the old SCPI driver addressing possible
user-after-free issues.

Add an SCMI System Power control driver to handle platform's requests
carried by SYSTEM_POWER_STATE_NOTIFIER notifications: such platform
requested system-wide power state transitions are handled accordingly,
gracefully or forcefully, depending on the notifications' message flags.
Graceful requests are relayed to userspace using the same Kernel API used
to handle ACPI Shutdown bus events.

Add a method to get hold of a protocol, causing it to be initialized and
its resource accounting updated, without getting access to its operations
and handle.
Some protocols, like SCMI SystemPower, do not expose any protocol ops to
the kernel OSPM agent but still need to be at least initialized. This
helper avoids the need to invoke a full devm_get_protocol() only to get
the protocol initialized while throwing away unused the protocol ops and
handle.

In order to minimize SCMI platform fw-side complexity, only one single SCMI
platform should be in charge of SCMI SystemPower protocol communications
with the OSPM. Enforce the existence of one single unique device associated
with SystemPower protocol across any possible number of SCMI platforms, and
warn if a system tries to register different SystemPower devices from
multiple platforms.

When scpi probe fails, at any point, we need to ensure that the scpi_info
is not set and will remain NULL until the probe succeeds. If it is not
taken care, then it could result use-after-free as the value is exported
via get_scpi_ops() and could refer to a memory allocated via devm_kzalloc()
but freed when the probe fails.
