https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux into soc/dt RISC-V Misc Devicetrees for v6.18 Starfive: The main new addition is support for the JH7110 Milk-V Mars CM lite SoM. Other than that, there's several cleanups done to the common JH7110 dtsi file, some relating to properties used by U-Boot or encountered during U-Boot development. Additionally, there's a binding and devicetree node for the memory controller on the JH7110. The memory controller only sees use in U-Boot, so the binding is here rather than in Krzysztof's branch. SiFive: Support for SiFive vendor-specific extensions in the binding file for extensions. These currently only see use in the SBI implementation. Microchip: Addition of support for the PolarFire SoC Discovery kit and non-engineering sample Icicle kit. The latter differs very slightly from the final ES devices due to bug fixes affecting functionality, and needs its own dts. To reduce duplication, the common portion of the two Icicle kits are moved into a dtsi. There's a few minor fixes here too, mostly low-hanging fruit detected during the addition of the Discovery kit that were then applied to the Icicle.

2025-09-25kconfig: Add transitional symbol attribute for migration supportKees Cook1-0/+32
During kernel option migrations (e.g. CONFIG_CFI_CLANG to CONFIG_CFI), existing .config files need to maintain backward compatibility while preventing deprecated options from appearing in newly generated configurations. This is challenging with existing Kconfig mechanisms because: 1. Simply removing old options breaks existing .config files. 2. Manually listing an option as "deprecated" leaves it needlessly visible and still writes them to new .config files. 3. Using any method to remove visibility (.e.g no 'prompt', 'if n', etc) prevents the option from being processed at all. Add a "transitional" attribute that creates symbols which are: - Processed during configuration (can influence other symbols' defaults) - Hidden from user menus (no prompts appear) - Omitted from newly written .config files (gets migrated) - Restricted to only having help sections (no defaults, selects, etc) making it truly just a "prior value pass-through" option. The transitional syntax requires a type argument and prevents type redefinition: config NEW_OPTION bool "New option" default OLD_OPTION config OLD_OPTION bool transitional help Transitional config for OLD_OPTION migration. This allows seamless migration: olddefconfig processes existing CONFIG_OLD_OPTION=y settings to enable CONFIG_NEW_OPTION=y, while CONFIG_OLD_OPTION is omitted from newly generated .config files. Added positive and negative testing via "testconfig" make target.

2025-09-25dt-bindings: touchscreen: add debounce-delay-us propertyDario Binacchi1-0/+4
Add support for glitch delay configuration. A detected signal is valid only if it remains stable longer than the configured delay; otherwise, it is considered a glitch. This property was introduced for the i.MX6UL touchscreen controller (TSC), which provides a hardware deglitch filter with four thresholds depending on the IPG clock frequency. In this use case, the IPG clock rate is 66 MHz, resulting in thresholds of 124 µs, 62 µs, 31 µs, and 15 µs, which requires a property with microsecond-level resolution.

2025-09-24hwmon: (dell-smm) Add support for automatic fan modeArmin Wolf1-21/+35
Many machines treat fan state 3 as some sort of automatic mode, which is superior to the separate SMM calls for switching to automatic fan mode for two reasons: - the fan control mode can be controlled for each fan separately - the current fan control mode can be retrieved from the BIOS On some machines however, this special fan state does not exist. Fan state 3 acts like a regular fan state on such machines or does not exist at all. Such machines usually use separate SMM calls for enabling/disabling automatic fan control. Add support for it. If the machine supports separate SMM calls for changing the fan control mode, then the other interface is ignored.

git://git.kernel.org/pub/scm/linux/kernel/git/jenswi/linux-tee into soc/drivers Add Qualcomm TEE driver (QTEE) This introduces a Trusted Execution Environment (TEE) driver for Qualcomm TEE (QTEE). QTEE enables Trusted Applications (TAs) and services to run securely. It uses an object-based interface, where each service is an object with sets of operations. Kernel and userspace services are also available to QTEE through a similar approach. QTEE makes callback requests that are converted into object invocations. These objects can represent services within the kernel or userspace process. We extend the TEE subsystem to understand object parameters and an ioctl call so client can invoke objects in QTEE: - TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF_* - TEE_IOC_OBJECT_INVOKE The existing ioctl calls TEE_IOC_SUPPL_RECV and TEE_IOC_SUPPL_SEND are used for invoking services in the userspace process by QTEE. The TEE backend driver uses the QTEE Transport Message to communicate with QTEE. Interactions through the object INVOKE interface are translated into QTEE messages. Likewise, object invocations from QTEE for userspace objects are converted into SEND/RECV ioctl calls to supplicants. * tag 'tee-qcomtee-for-v6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/jenswi/linux-tee: Documentation: tee: Add Qualcomm TEE driver tee: qcom: enable TEE_IOC_SHM_ALLOC ioctl tee: qcom: add primordial object tee: add Qualcomm TEE driver tee: increase TEE_MAX_ARG_SIZE to 4096 tee: add TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF tee: add TEE_IOCTL_PARAM_ATTR_TYPE_UBUF tee: add close_context to TEE driver operation tee: allow a driver to allocate a tee_device without a pool Link: https://lore.kernel.org/r/20250915174957.GA2040478@rayden Signed-off-by: Arnd Bergmann <arnd@arndb.de>

https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into soc/dt Allwinner Device Tree changes for 6.18 This tag contains two DT binding header changes that are shared with the clk tree. In this cycle we gained support for the MCU PRCM clock and reset controller on the A523/A527/T527 family of SoCs, the NPU which is a Vivante GC9000 IP block, and the NPU clock that was missing. The other PRCM clock controller gained default bus clock rate settings. These were not configured in the upstream U-boot bootloader, leading to them running at slower rates. The assigned rates are from the user manual. There is also a new board, the NetCube Systems Nagami SoM and two of its carrier boards. The A523 family development boards now have their internal RTC clocks configured correctly, so that the RTC does not drift wildly. The missing functions for the AXP717 on these boards are added. Missing reset GPIOs and delays for Ethernet PHYs are added. Last, the Cubie A5E now has its LEDs described and usable. An overlay for the Orange Pi Zero interface (addon) board was added. This can be used with the Orange Pi Zero and Zero Plus 2. Default audio routing for these two boards (to be used with the addon) were added to complement the overlay. * tag 'sunxi-dt-for-6.18' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux: arm64: dts: allwinner: sun55i: Complete AXP717A sub-functions arm64: dts: allwinner: t527: orangepi-4a: hook up external 32k crystal arm64: dts: allwinner: t527: avaota-a1: hook up external 32k crystal arm64: dts: allwinner: a527: cubie-a5e: Drop external 32.768 KHz crystal arm64: dts: sun55i: a523: Assign standard clock rates to PRCM bus clocks ARM: dts: sunxi: add support for NetCube Systems Nagami Keypad Carrier ARM: dts: sunxi: add support for NetCube Systems Nagami Basic Carrier ARM: dts: sunxi: add support for NetCube Systems Nagami SoM riscv: dts: allwinner: d1s-t113: Add pinctrl's required by NetCube Systems Nagami SoM dt-bindings: arm: sunxi: Add NetCube Systems Nagami SoM and carrier board bindings ARM: dts: allwinner: Add Orange Pi Zero Interface Board overlay ARM: dts: allwinner: orangepi-zero-plus2: Add default audio routing ARM: dts: allwinner: orangepi-zero: Add default audio routing arm64: dts: allwinner: a523: Add NPU device node arm64: dts: allwinner: a523: Add MCU PRCM CCU node dt-bindings: clock: sun55i-a523-ccu: Add A523 MCU CCU clock controller dt-bindings: clock: sun55i-a523-ccu: Add missing NPU module clock arm64: dts: allwinner: t527: avaota-a1: Add ethernet PHY reset setting arm64: dts: allwinner: a527: cubie-a5e: Add ethernet PHY reset setting arm64: dts: allwinner: a527: cubie-a5e: Add LEDs Link: https://lore.kernel.org/r/aMrtuZg8HlR--TAt@wens.tw Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2025-09-23KVM: x86: Enable guest SSP read/write interface with new uAPIsYang Weijiang1-0/+8
Add a KVM-defined ONE_REG register, KVM_REG_GUEST_SSP, to let userspace save and restore the guest's Shadow Stack Pointer (SSP). On both Intel and AMD, SSP is a hardware register that can only be accessed by software via dedicated ISA (e.g. RDSSP) or via VMCS/VMCB fields (used by hardware to context switch SSP at entry/exit). As a result, SSP doesn't fit in any of KVM's existing interfaces for saving/restoring state. Internally, treat SSP as a fake/synthetic MSR, as the semantics of writes to SSP follow that of several other Shadow Stack MSRs, e.g. the PLx_SSP MSRs. Use a translation layer to hide the KVM-internal MSR index so that the arbitrary index doesn't become ABI, e.g. so that KVM can rework its implementation as needed, so long as the ONE_REG ABI is maintained. Explicitly reject accesses to SSP if the vCPU doesn't have Shadow Stack support to avoid running afoul of ignore_msrs, which unfortunately applies to host-initiated accesses (which is a discussion for another day). I.e. ensure consistent behavior for KVM-defined registers irrespective of ignore_msrs.

2025-09-23KVM: x86: Introduce KVM_{G,S}ET_ONE_REG uAPIs supportYang Weijiang1-1/+5
Enable KVM_{G,S}ET_ONE_REG uAPIs so that userspace can access MSRs and other non-MSR registers through them, along with support for KVM_GET_REG_LIST to enumerate support for KVM-defined registers. This is in preparation for allowing userspace to read/write the guest SSP register, which is needed for the upcoming CET virtualization support. Currently, two types of registers are supported: KVM_X86_REG_TYPE_MSR and KVM_X86_REG_TYPE_KVM. All MSRs are in the former type; the latter type is added for registers that lack existing KVM uAPIs to access them. The "KVM" in the name is intended to be vague to give KVM flexibility to include other potential registers. More precise names like "SYNTHETIC" and "SYNTHETIC_MSR" were considered, but were deemed too confusing (e.g. can be conflated with synthetic guest-visible MSRs) and may put KVM into a corner (e.g. if KVM wants to change how a KVM-defined register is modeled internally). Enumerate only KVM-defined registers in KVM_GET_REG_LIST to avoid duplicating KVM_GET_MSR_INDEX_LIST, and so that KVM can return _only_ registers that are fully supported (KVM_GET_REG_LIST is vCPU-scoped, i.e. can be precise, whereas KVM_GET_MSR_INDEX_LIST is system-scoped).

2025-09-23dt-bindings: arm: Add label in the coresight componentsMao Jinlong15-0/+60
Current name of coresight component's folder consists of prefix of the device and the id in the device list. When run 'ls' command, we can get the register address of the device. Take CTI for example, if we want to set the config for modem CTI, but we can't know which CTI is modem CTI from all current information. cti_sys0 -> ../../../devices/platform/soc@0/138f0000.cti/cti_sys0 cti_sys1 -> ../../../devices/platform/soc@0/13900000.cti/cti_sys1 Add label to show hardware context information of each coresight device. There will be a sysfs node label in each device folder. cat /sys/bus/coresight/devices/cti_sys0/label Signed-off-by: Mao Jinlong <quic_jinlmao@quicinc.com> Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Reviewed-by: Mike Leach <mike.leach@linaro.org> Signed-off-by: Suzuki K Poulose <suzuki.poulose@arm.com> Link: https://lore.kernel.org/r/20250816072529.3716968-2-quic_jinlmao@quicinc.com

Features ======== Core - New helper to multiply data expressed in IIO types. - Add KUnit tests. - New IIO_ALTCURRENT type, similar to existing IIO_ALTVOLTAGE - Add some channel modifiers related to energy and power, such as reactive. adi,ad7124 - Support external clocks sources and output of the internal clocks. - Filter control. adi,ad7173 - Add filter support. Some fiddly interactions with other parameters on this device. adi,ad7779 - Add backend support which required control of the number of lanes used. liteon,ltr390 - Add runtime PM support. microchip,mcp9600 - Add support for different thermocouple types. Cleanup and minor fixes ======================= core - Switch info_mask fields to be unsigned. Not clear why they were ever signed. - Fix handling of negative channel scale in iio_convert_raw_to_processed() - Fix offset handling for channels without a scale attribute. - Improve the precision of scaling slightly. - Drop apparent handling of IIO_CHAN_INFO_PROCESSED for devices that don't have any such channels. various - Drop many pm_runtime_mark_last_busy() calls now pm_runtime_put_autosuspend() calls it internally. - Drop dev_err_probe() calls where the error code is hard coded as -ENOMEM as they don't do anything. - Drop dev_err() calls where the error code is -ENOMEM. This will reduce error prints, but memory failures generate a lot of messages anyway so unlikely we need these prints. current-sense-amplifier - Add #io-channels property this channel to be used by a consumer driver. adi,ad7124 - Fix incorrect clocks dt-binding property. - Make the mclk clock optional in DT - this is internal to the ADC so should never have been in he binding. - Fix up sample rate to comply with ABI. - Use read_avail() callback rather than opencoding similar. - Deploy guard() to clean up some lock handling. adi,ad7768 - Use devm_regulator_get_enable_read_voltage() to replace similar code. adi,ad7816 - Drop an unnecessary dev_set_drvdata() call as nothing uses the data. ad,adxl345 - Fix missing blank line before bullet list in documentation. arm,scmi - Use devm_kcalloc() for an array allocation rather than devm_kzalloc(). bosch,bmi270 - Match an ACPI ID seen in the wild.

2025-09-23VFS: rename kern_path_locked() and related functions.NeilBrown1-0/+12
kern_path_locked() is now only used to prepare for removing an object from the filesystem (and that is the only credible reason for wanting a positive locked dentry). Thus it corresponds to kern_path_create() and so should have a corresponding name. Unfortunately the name "kern_path_create" is somewhat misleading as it doesn't actually create anything. The recently added simple_start_creating() provides a better pattern I believe. The "start" can be matched with "end" to bracket the creating or removing. So this patch changes names: kern_path_locked -> start_removing_path kern_path_create -> start_creating_path user_path_create -> start_creating_user_path user_path_locked_at -> start_removing_user_path_at done_path_create -> end_creating_path and also introduces end_removing_path() which is identical to end_creating_path(). __start_removing_path (which was __kern_path_locked) is enhanced to call mnt_want_write() for consistency with the start_creating_path().

2025-09-23spi: rpc-if: Add resume support for RZ/G3EMark Brown3-8/+7
Merge series from Biju Das <biju.das.jz@bp.renesas.com>: On RZ/G3E using PSCI, s2ram powers down the SoC. After resume, reinitialize the hardware for SPI operations. Also Replace the macro SIMPLE_DEV_PM_OPS->DEFINE_SIMPLE_DEV_PM_OPS macro and use pm_sleep_ptr(). This lets us drop the check for CONFIG_PM_SLEEP and __maybe_unused attribute from PM functions.
