Pull remoteproc updates from Bjorn Andersson:
- Add i.MX94 support to the i.MX remoteproc driver, covering the
Cortex-M7 and Cortex-M33 Sync cores. This also fixes programming of
non-zero System Manager CPU/LMM reset vectors.
- Move the remoteproc resource table definitions to a separate header,
so they can be used by clients that do not otherwise depend on
remoteproc. Switch the firmware resource handling over to the common
iterator.
- Update the Xilinx R5F remoteproc driver to check the remote core
state before attaching, drop a binding header dependency, and add
firmware-name based auto boot support.
- Add Qualcomm Hawi ADSP/CDSP bindings, together with Shikra RPM
bindings and CDSP, LPAICP, and MPSS PAS support. Fix a Qualcomm
minidump leak, clean up PAS and WCSS reset handling, and make the
user-visible Qualcomm naming consistent.
- Remove a duplicate STM32_RPROC Kconfig dependency and make i.MX
remoteproc instances use the device node name so multiple processors
can be distinguished in sysfs.

Add entry in Stratix10 service layer that allow client to retrieve the ATF
version at runtime, which is useful for system diagnostics, compatibility
checks, and ensuring the correct secure firmware is in use.
The change introduces:
- A new service command definition in the Stratix10 service layer to
initiate the ATF version query.
- A corresponding macro definition in the header file to expose the command
ID for use by other components.
The service layer uses a Secure Monitor Call (SMC) to communicate with the
ATF and retrieve the version string, which can then be logged or validated
by client application.

Sashiko reported an inconsistent use of NULL vs ERR_PTR()
returns in the stub helpers in xynos-acpm-protocol.h.
Since this only happens on dead code for COMPILE_TEST=y, this is not
really a bug though. Having stub functions that return NULL is a common
way to define optional interfaces, where callers still work when the
feature is disabled, though this clearly does not work for acpm because
some callers have a NULL pointer dereference when compile testing.
Since CONFIG_EXYNOS_ACPM_PROTOCOL already supports compile-testing itself,
and all (both) drivers using it clearly require the support, so this
just simplifies the option space without losing any build coverage.
Remove the stub functions entirely and adjust the one Kconfig
dependency to require EXYNOS_ACPM_PROTOCOL unconditionally.

Introduce devm_acpm_get_by_phandle() to standardize how consumer
drivers acquire a handle to the ACPM IPC interface. Enforce the
use of the "samsung,acpm-ipc" property name across the SoC and
simplify the boilerplate code in client drivers.
The first consumer of this helper is the Exynos ACPM Thermal Management
Unit (TMU) driver. The TMU utilizes a hybrid management approach: direct
register access from the Application Processor (AP) is restricted to the
interrupt pending (INTPEND) registers for event identification.
High-level functional tasks, such as sensor initialization, threshold
programming, and temperature reads, are delegated to the ACPM firmware
via this IPC interface.

Replace the embedded `struct acpm_ops` inside `struct acpm_handle` with
a pointer to a `const struct acpm_ops`.
Previously, the operations structure was embedded directly within the
handle and populated dynamically at runtime via `acpm_setup_ops()`.
This resulted in mutable function pointers and unnecessary per-instance
memory overhead.
By defining `exynos_acpm_driver_ops` statically as a `const` structure,
the function pointers are now safely housed in the read-only `.rodata`
section. This improves security by preventing function pointer
overwrites, saves memory, and slightly reduces initialization overhead
in `acpm_probe()`.
Consequently, update all consumer drivers (clk, mfd) to access the
operations via the new pointer indirection (`->ops->`). Finally, fix
the previously empty kernel-doc description for the ops member to
reflect its new pointer nature.

Rename the `dvfs_ops` and `pmic_ops` members of `struct acpm_ops` to
`dvfs` and `pmic` respectively.
Since these members are housed within the `acpm_ops` structure and
utilize the `acpm_*_ops` types, the `_ops` suffix on the variable names
creates unnecessary redundancy (e.g., `handle.ops.dvfs_ops`).
This cleanup removes the stuttering, leading to cleaner consumer code.

Add support for dynamically discovering and exposing Configuration
Security Unit (CSU) registers through sysfs. Leverage the existing
PM_QUERY_DATA API to discover available registers at runtime, making
the interface flexible and maintainable.
Key features:
- Dynamic register discovery using PM_QUERY_DATA API
* PM_QID_GET_NODE_COUNT: Query number of available registers
* PM_QID_GET_NODE_NAME: Query register names by index
- Automatic sysfs attribute creation under csu_registers/ group
- Read operations via existing IOCTL_READ_REG API
- Write operations via existing IOCTL_MASK_WRITE_REG API
The sysfs interface is created at:
/sys/devices/platform/firmware:zynqmp-firmware/csu_registers/
Currently supported registers include:
- multiboot (CSU_MULTI_BOOT)
- idcode (CSU_IDCODE, read-only)
- pcap-status (CSU_PCAP_STATUS, read-only)
The dynamic discovery approach allows firmware to control which
registers are exposed without requiring kernel changes, improving
maintainability and security.
The firmware does not currently expose per-register access mode
information, so the kernel cannot distinguish read-only registers
from read-write ones at discovery time. All discovered registers are
therefore created with sysfs mode 0644, and the firmware is
responsible for rejecting writes to registers it treats as read-only
(for example idcode and pcap-status); that error is propagated back
to userspace from the store callback. If a per-register access-mode
query is added to the firmware in the future, sysfs permissions can
be tightened to match.
CSU register discovery is an optional feature: on firmware that lacks
support for PM_QID_GET_NODE_COUNT or PM_QID_GET_NODE_NAME, the probe
returns gracefully without exposing any sysfs entries. To keep the
memory footprint minimal on that path, partial devm allocations made
during discovery are explicitly released on failure so that no memory
lingers until device unbind when the feature is unavailable.

The remote state is set to RPROC_DETACHED if the resource table is found
in the memory. However, this can be wrong if the remote is not started,
but firmware is still loaded in the memory. Use PM_GET_NODE_STATUS call
to the firmware to request the state of the RPU node. If the RPU is
actually out of reset and running, only then move the remote state to
RPROC_DETACHED, otherwise keep the remote state to RPROC_OFFLINE.

Addresses two issues in the TH1520 AON firmware protocol driver:
1. Fix a potential buffer overflow where the code used unsafe pointer
arithmetic to access the 'mode' field through the 'resource' pointer
with an offset. This was flagged by Smatch static checker as:
"buffer overflow 'data' 2 <= 3"
2. Replace custom RPC_SET_BE* and RPC_GET_BE* macros with standard
kernel endianness conversion macros (cpu_to_be16, etc.) for better
portability and maintainability.
The functionality was re-tested with the GPU power-up sequence,
confirming the GPU powers up correctly and the driver probes
successfully.

In the current implementation, SVC client drivers such as socfpga-hwmon,
intel_fcs, stratix10-soc, stratix10-rsu each send an SMC command that
triggers a single thread in the stratix10-svc driver. Upon receiving a
callback, the initiating client driver sends a stratix10-svc-done signal,
terminating the thread without waiting for other pending SMC commands to
complete. This leads to a timeout issue in the firmware SVC mailbox service
when multiple client drivers send SMC commands concurrently.
To resolve this issue, a dedicated thread is now created per channel. The
stratix10-svc driver will support up to the number of channels defined by
SVC_NUM_CHANNEL. Thread synchronization is handled using a mutex to prevent
simultaneous issuance of SMC commands by multiple threads.
SVC_NUM_DATA_IN_FIFO is reduced from 32 to 8, since each channel now has
its own dedicated FIFO and the SDM processes commands one at a time.
8 entries per channel is sufficient while keeping the total aggregate
capacity the same (4 channels x 8 = 32 entries).
Additionally, a thread task is now validated before invoking kthread_stop
when the user aborts, ensuring safe termination.

For some parts, the DSP is kept running when in low power mode
(hibernation), leaving the firmware ALSA controls enabled, but the
registers are inaccessible. Attempts to access volatile firmware
controls whilst in this state would produce errors in the kernel log
due to a regmap_raw_read() into DSP registers whilst the regmap is in
cache_only.
To remove this error log, add a hibernating flag to indicate that the
controls are inaccessible, so we no longer try to read or write to the
registers whilst the regmap is in cache_only.
This would still produce an error when trying to read or write to these
controls, but this would be a different error (-EPERM instead of
-EBUSY), and would not produce a spurious error log in the kernel.
Upon wake from hibernation, the control caches are re-synced to the
hardware, if the DSP is running.

All the functions operating on the 'handle' pointer are claiming it is a
pointer to const thus they should not modify the handle. In fact that's
a false statement, because first thing these functions do is drop the
cast to const with container_of:
struct acpm_info *acpm = handle_to_acpm_info(handle);
And with such cast the handle is easily writable with simple:
acpm->handle.ops.pmic_ops.read_reg = NULL;
The code is not correct logically, either, because functions like
acpm_get_by_node() and acpm_handle_put() are meant to modify the handle
reference counting, thus they must modify the handle. Modification here
happens anyway, even if the reference counting is stored in the
container which the handle is part of.
The code does not have actual visible bug, but incorrect 'const'
annotations could lead to incorrect compiler decisions.

One of SAI interfaces is connected to AUDMIX in the i.MX952 chip, but
AUDMIX can be bypassed or not bypassed on the i.MX952 platform.
There are three use cases:
1) SAI -> Codec (No AUDMIX between SAI and Codec)
2) SAI -> Codec (Has AUDMIX, but AUDMIX is bypassed)
3) SAI -> AUDMIX -> Codec (Has AUDMIX and used)
So add 'fsl,sai-amix-mode' property for this feature
fsl,sai-amix-mode = "none": is for case 1)
fsl,sai-amix-mode = "bypass": is for case 2)

Qualcomm remote processor may rely on Static and Dynamic resources for
it to be functional. Static resources are fixed like for example,
memory-mapped addresses required by the subsystem and dynamic
resources, such as shared memory in DDR etc., are determined at
runtime during the boot process.
For most of the Qualcomm SoCs, when run with Gunyah or older QHEE
hypervisor, all the resources whether it is static or dynamic, is
managed by the hypervisor. Dynamic resources if it is present for a
remote processor will always be coming from secure world via SMC call
while static resources may be present in remote processor firmware
binary or it may be coming qcom_scm_pas_get_rsc_table() SMC call along
with dynamic resources.
Some of the remote processor drivers, such as video, GPU, IPA, etc., do
not check whether resources are present in their remote processor
firmware binary. In such cases, the caller of this function should set
input_rt and input_rt_size as NULL and zero respectively. Remoteproc
framework has method to check whether firmware binary contain resources
or not and they should be pass resource table pointer to input_rt and
resource table size to input_rt_size and this will be forwarded to
TrustZone for authentication. TrustZone will then append the dynamic
resources and return the complete resource table in the passed output
buffer.
More about documentation on resource table format can be found in
include/linux/remoteproc.h

For memory passed to TrustZone (TZ), it must either be part of a pool
registered with TZ or explicitly registered via SHMbridge SMC calls.
When Gunyah hypervisor is present, PAS SMC calls from Linux running at
EL1 are trapped by Gunyah running @ EL2, which handles SHMbridge
creation for both metadata and remoteproc carveout memory before
invoking the calls to TZ.
On SoCs running with a non-Gunyah-based hypervisor, Linux must take
responsibility for creating the SHM bridge before invoking PAS SMC
calls. For the auth_and_reset() call, the remoteproc carveout memory
must first be registered with TZ via a SHMbridge SMC call and once
authentication and reset are complete, the SHMbridge memory can be
deregistered.
Introduce qcom_scm_pas_prepare_and_auth_reset(), which sets up the SHM
bridge over the remoteproc carveout memory when Linux operates at EL2.
This behavior is indicated by a new field added to the PAS context data
structure. The function then invokes the auth_and_reset SMC call.

As a superset of the existing metadata context, the PAS context
structure enables both remoteproc and non-remoteproc subsystems to
better support scenarios where the SoC runs with or without the Gunyah
hypervisor. To reflect this, relevant SCM and metadata functions are
updated to incorporate PAS context awareness and remove metadata context
data structure completely.

When the Peripheral Authentication Service (PAS) method runs on a SoC
where Linux operates at EL2 (i.e., without the Gunyah hypervisor), the
reset sequences are handled by TrustZone. In such cases, Linux must
perform additional steps before invoking PAS SMC calls, such as creating
a SHM bridge. Therefore, PAS SMC calls require awareness and handling of
these additional steps when Linux runs at EL2.
To support this, there is a need for a data structure that can be
initialized prior to invoking any SMC or MDT functions. This structure
allows those functions to determine whether they are operating in the
presence or absence of the Gunyah hypervisor and behave accordingly.
Currently, remoteproc and non-remoteproc subsystems use different
variants of the MDT loader helper API, primarily due to differences in
metadata context handling. Remoteproc subsystems retain the metadata
context until authentication and reset are completed, while
non-remoteproc subsystems (e.g., video, graphics, IPA, etc.) do not
retain the metadata context and can free it within the
qcom_scm_pas_init() call by passing a NULL context parameter and due to
these differences, it is not possible to extend metadata context
handling to support remoteproc and non remoteproc subsystem use PAS
operations, when Linux operates at EL2.
Add PAS context data structure allocator helper function.

Add an argument to cs_dsp_mock_bin_add_raw_block() to pass a 32-bit
offset, and change the type of the existing offset argument to u16.
The cs_dsp_test_bin_error.c test uses cs_dsp_mock_bin_add_raw_block()
so it needs corresponding updates to pass 0 as the 32-bit offset.
Version 1 and 2 of the bin file format had a 16-bit offset on blocks
and the sample rate field of the blocks was not used. Version 3 adds
new block types that change the old sample rate field to be a 32-bit
offset with the old offset currently unused.
cs_dsp_mock_bin_add_raw_block() doesn't attempt to do any magic - its
purpose is to create a raw block exactly as specified by the calling
test code. So the test case can pass a value for both offset fields.

Handle a new type of data block that has a 32-bit offset. These are
identical to the normal blocks except that the offset is now in the
32-bit field that was previously 'sr'.
A new file version of 3 indicates that it is mandatory to process
the long-offset blocks, so that older code without that support will
reject the file.
The original 'sr' field was never used by the driver so it has been
renamed offset32.

Qualcomm driver updates for v6.19
Support for hardware-keymanager v1 support for wrapped keys is introduce
in the ICE driver.
Support for the new Kaanapali mobile platform is added to last-level
cache controller, pd-mapper, and UBWC drivers.
UBWC driver gains support for the Monaco and Glymur platforms.
The PMIC GLINK driver is extended to handle the differences found in
targets where the related firmware runs on the SoCCP.
Support for running on targets without initialized SMEM is provided, by
reworking the SMEM driver to differentiate between "not yet probed" and
"probed but there was no SMEM". An unwanted WARN_ON() that triggered if
clients asked for a SMEM item beyond the currently running system's
limit, was removed, to allow new use cases to gracefully fail on old
targets.
The Qualcomm socinfo driver is extended with support for version 20
through 23 and support for providing version information about more than
32 remote processors. Identifiers for QCS6490 and SM8850 are also added.
Additionally, a number of smaller bug fixes and cleanups in PBS, OCMEM,

The architectures supported by this driver have a maximum of 32-bits
of address, so we don't need more than 32-bits to store the length of
control data. Change the length in struct cs_dsp_coeff_ctl to an
unsigned int instead of a size_t. Also make a corresponding trivial
change to wm_adsp.c to prevent a compiler warning.
Tested on x86_64 builds this saves at least 4 bytes per control
(another 4 bytes might be saved if the compiler was inserting padding
to align the size_t).

cs_dsp_debugfs_wmfw_read() and cs_dsp_debugfs_bin_read() were identical
except for which struct member they printed. Move all this duplicated
code into a common function cs_dsp_debugfs_string_read().
The check for dsp->booted has been removed because this is redundant.
The two strings are set when the DSP is booted and cleared when the
DSP is powered-down.
Access to the string char * must be protected by the pwr_lock mutex. The
string is passed into cs_dsp_debugfs_string_read() as a pointer to the
char * so that the mutex lock can also be factored out into
cs_dsp_debugfs_string_read().
wmfw_file_name and bin_file_name members of struct cs_dsp have been
changed to const char *. It makes for a better API to pass a const
pointer into cs_dsp_debugfs_string_read().

Integrate Remote System Update(RSU) service commands into the
asynchronous framework for communicating with SDM. This allows the RSU
commands to be processed asynchronously, improving the responsiveness
of the Stratix10 service channel.
The asynchronous framework now supports the following RSU commands:
* COMMAND_RSU_GET_SPT_TABLE
* COMMAND_RSU_STATUS
* COMMAND_RSU_NOTIFY

Introduce support for asynchronous communication with the Stratix10
service channel. Define new structures to enable asynchronous messaging
with the Secure Device Manager (SDM). Add and remove asynchronous
support for existing channels. Implement initialization and cleanup
routines for the asynchronous framework. Enable sending and polling of
messages to the SDM asynchronously.
The new public functions added are:
- stratix10_svc_add_async_client: Adds a client to the service channel.
- stratix10_svc_remove_async_client: Removes an asynchronous client from
the service channel.
- stratix10_svc_async_send: Sends an asynchronous message to the SDM
mailbox in EL3 secure firmware.
- stratix10_svc_async_poll: Polls the status of an asynchronous service
request in EL3 secure firmware.
- stratix10_svc_async_done: Marks an asynchronous transaction as
complete and frees up the resources.
These changes enhance the functionality of the Stratix10 service channel
by allowing for more efficient and flexible communication with the
firmware.

Add support for a generic ioctl read/write interface using which users
can request firmware to perform read/write operations on a protected and
secure address space.
The functionality is introduced through the means of two new IOCTL IDs
which extend the existing PM_IOCTL EEMI API:
- IOCTL_READ_REG
- IOCTL_MASK_WRITE_REG
The caller only passes the node id of the given device and an offset.
The base address is not exposed to the caller and internally retrieved
by the firmware. Firmware will enforce an access policy on the incoming
read/write request.
