Linus Torvalds ba65a4e712 This pull request is entirely SoC clk drivers, not for lack of trying to modify
the core clk framework. The majority diff wise is for the new Rockchip and
 Qualcomm clk drivers which is mostly lines and lines of data structures to
 describe the clk hardware in these SoCs. Beyond those two, Renesas continues to
 incrementally add clks to their SoC drivers, causing them to show up higher in
 the diffstat this time because they added quite a few clks all over the place.
 Overall it is a semi-quiet release that has some new clk drivers and the usual
 fixes for clock data that was wrong or missing and non-critical cleanups that
 plug error paths or fix typos.
 
 New Drivers:
  - Qualcomm IPQ5424 Network Subsystem Clock Controller
  - Qualcomm SM8750 Video Clock Controller
  - Rockchip RV1126B and RK3506 clock drivers
  - i.MX8ULP SIM LPAV clock driver
  - Samsung ACPM (firmware interface) clock driver
  - Altera Agilex5 clock driver

Linus Torvalds 83bd89291f Char/Misc/IIO driver updates for 6.19-rc1
Here is the big set of char/misc/iio driver updates for 6.19-rc1.  Lots
 of stuff in here including:
   - lots of IIO driver updates, cleanups, and additions.
   - large interconnect driver changes as they get converted over to a
     dynamic system of ids
   - coresight driver updates
   - mwave driver updates
   - binder driver updates and changes
   - comedi driver fixes now that the fuzzers are being set loose on them
   - nvmem driver updates
   - new uio driver addition
   - lots of other small char/misc driver updates, full details in the
     shortlog
 
 All of these have been in linux-next for a while now, with no reported
 issues other than a merge conflict with your tree that should be trivial
 to handle (take both sides).

Arnd Bergmann 3d497bf8ef 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,
 GSBI, TZMEM, and MDT-loader are included.

firmware: cs_dsp: Store control length as 32-bit
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).

firmware: cs_dsp: Factor out common debugfs string read
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().

Mahesh Rao ec52379341 firmware: stratix10-svc: Add support for RSU commands in asynchronous framework
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

Mahesh Rao bcb9f4f070 firmware: stratix10-svc: Add support for async communication
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

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

Amirreza Zarrabi 4b700098c0 firmware: qcom: scm: add support for object invocation
Qualcomm TEE (QTEE) hosts Trusted Applications (TAs) and services in
the secure world, accessed via objects. A QTEE client can invoke these
objects to request services. Similarly, QTEE can request services from
the nonsecure world using objects exported to the secure world.

Add low-level primitives to facilitate the invocation of objects hosted
in QTEE, as well as those hosted in the nonsecure world.

If support for object invocation is available, the qcom_scm allocates
a dedicated child platform device. The driver for this device communicates
with QTEE using low-level primitives.

The original change aimed to simplify the handling of optional features by
removing conditional stubs. However, the use of conditional stubs is
necessary when CONFIG_IMX_SCMI_MISC_DRV is n, while consumer driver is
set to y.

This is not a matter of preserving legacy patterns, but rather to ensure

Madhav Bhatt 548fe51740 firmware: xilinx: Add debugfs support for PM_GET_NODE_STATUS
Add new debug interface to support PM_GET_NODE_STATUS to get the node
information like requirements and usage.

The debugfs firmware driver interface is only meant for testing and
debugging EEMI APIs. Hence, it is by-default disabled in production
systems.

Bartosz Golaszewski dc3f4e75c5 firmware: qcom: scm: take struct device as argument in SHM bridge enable
qcom_scm_shm_bridge_enable() is used early in the SCM initialization
routine. It makes an SCM call and so expects the internal __scm pointer
in the SCM driver to be assigned. For this reason the tzmem memory pool
is allocated *after* this pointer is assigned. However, this can lead to
a crash if another consumer of the SCM API makes a call using the memory
pool between the assignment of the __scm pointer and the initialization
of the tzmem memory pool.

As qcom_scm_shm_bridge_enable() is a special case, not meant to be
called by ordinary users, pull it into the local SCM header. Make it
take struct device as argument. This is the device that will be used to
make the SCM call as opposed to the global __scm pointer. This will
allow us to move the tzmem initialization *before* the __scm assignment
in the core SCM driver.

firmware: cs_dsp: Remove unused struct list_head from cs_dsp_coeff_ctl
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.

Arnd Bergmann 4e61c011b0 Arm SCMI updates for v6.16
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.

   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.

André Draszik a8dc26a0ec firmware: exynos-acpm: introduce devm_acpm_get_by_node()
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.

firmware: cs_dsp: test_bin_error: Fix uninitialized data used as fw version
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.

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

Gaurav Kashyap 1d45a1cd9f firmware: qcom: scm: add calls for wrapped key support
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.]

firmware: cs_dsp: Add mock wmfw file generator for KUnit testing
Add a mock firmware file that emulates what the firmware build tools
would normally create. This will be used by KUnit tests to generate a
test wmfw file.

firmware: cs_dsp: Add mock DSP memory map for KUnit testing
Add helper functions to implement an emulation of the DSP memory map.

There are three main groups of functionality:

1. Define a mock cs_dsp_region table.
2. Calculate the addresses of memory and algorithms from the firmware
   header in XM.
3. Build a mock XM header in emulated XM.

firmware: cs_dsp: Add mock regmap for KUnit testing
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.
