Merge tag 'scmi-updates-6.16' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/driversArm SCMI updates for v6.161. 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 wellLink: https://lore.kernel.org/r/20250507134713.49039-1-sudeep.holla@arm.comSigned-off-by: Arnd Bergmann List of files: /linux/Documentation/ABI/testing/debugfs-scmi-raw
