https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers 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. * tag 'scmi-updates-6.16' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: quirk: Force perf level get fastchannel firmware: arm_scmi: quirk: Fix CLOCK_DESCRIBE_RATES triplet firmware: arm_scmi: Add common framework to handle firmware quirks firmware: arm_scmi: Ensure that the message-id supports fastchannel MAINTAINERS: add entry for i.MX SCMI extensions firmware: imx: Add i.MX95 SCMI CPU driver firmware: imx: Add i.MX95 SCMI LMM driver firmware: arm_scmi: imx: Add i.MX95 CPU Protocol firmware: arm_scmi: imx: Add i.MX95 LMM protocol dt-bindings: firmware: Add i.MX95 SCMI LMM and CPU protocol firmware: arm_scmi: imx: Add LMM and CPU documentation firmware: arm_scmi: Add polling support to raw mode firmware: arm_scmi: Exclude transport devices from bus matching firmware: arm_scmi: Assign correct parent to arm-scmi platform device firmware: arm_scmi: Refactor error logging from SCMI device creation to single helper firmware: arm_scmi: Refactor device matching logic to eliminate duplication firmware: arm_scmi: Ensure scmi_devices are always matched by name as well Link: https://lore.kernel.org/r/20250507134713.49039-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2025-04-22firmware: exynos-acpm: introduce devm_acpm_get_by_node()André Draszik
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.

2025-04-10firmware: cs_dsp: test_bin_error: Fix uninitialized data used as fw versionRichard Fitzgerald
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.

2025-01-08firmware: qcom: scm: add calls for wrapped key supportGaurav Kashyap
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.

2024-12-13firmware: cs_dsp: Add mock regmap for KUnit testingRichard Fitzgerald
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.

2024-10-02firmware: xilinx: use u32 for reset ID in reset APIsRonak Jain
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.

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.

2024-06-23firmware: qcom: add a dedicated TrustZone buffer allocatorBartosz Golaszewski
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.

2024-04-09firmware: qcom: uefisecapp: Fix memory related IO errors and crashesMaximilian Luz
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.

2024-01-04drivers: soc: xilinx: add check for platformJay Buddhabhatti
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.
