You will also see these commits coming in from other subsystems as with the relevant changes merged into mainline last cycle, I've started converting GPIO providers located elsewhere than drivers/gpio/. GPIO core: - use more lock guards where applicable - refactor GPIO ACPI code and shrink it in the process by 8% - move GPIO ACPI quirks into a separate file - remove unneeded #ifdef - convert GPIO devres helpers to using devm_add_action() where applicable which shrinks and simplifies the code - refactor GPIO descriptor validation in GPIO consumer interfaces - don't allow setting values on input lines in the GPIO core which will take off the burden from GPIO drivers of checking this down the line - provide gpiod_is_equal() as a way of safely comparing two GPIO descriptors (the only current user is in regulator core) New drivers: - add the GPIO module for the max77759 multifunction device - add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller - add the GPIO driver for the Spacemit K1 SoC Driver improvements: - convert more drivers to using the new GPIO line value setter callbacks - convert more drivers to making the irq_chip immutable as is recommended by the interrupt subsystem - extend build testing coverage by enabling more modules to be built with COMPILE_TEST=y - extend the gpio-aggregator module with a configfs interface that makes the setup easier for user-space than the existing driver-level sysfs attributes and also adds more advanced configuration features (such as referring to aggregated lines by their original names or modifying their names as exposed by the aggregated chip) - add a missing mutex_destroy() in gpio-imx-scu - add an OF polarity quirk for s5m8767 - allow building gpio-vf610 as a loadable module - make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS interface disabled (another small step towards getting rid of the global GPIO numberspace) - add support for level-triggered interrupts to gpio-pca953x - don't double-check the ngpios property in gpio-ds4520 as GPIO core already does it - don't double-check the number of GPIOs in gpio-imx-scu as GPIO core already does it - remove unused callbacks from gpio-max3191x DT bindings: - add device-tree bindings for max77759, spacemit,k1 and blzp1600 (new drivers added this cycle) - document more properties for gpio-vf610 and gpio-tegra186 - document a new pca95xx variant - fix style of examples in several GPIO DT-binding documents Misc: - TODO list updates" * tag 'gpio-updates-for-v6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (123 commits) gpio: timberdale: select GPIOLIB_IRQCHIP gpio: lpc18xx: select GPIOLIB_IRQCHIP gpio: grgpio: select GPIOLIB_IRQCHIP gpio: bcm-kona: select GPIOLIB_IRQCHIP dt-bindings: gpio: vf610: add ngpios and gpio-reserved-ranges gpio: davinci: select GPIOLIB_IRQCHIP gpiolib-acpi: Update file references in the Documentation and MAINTAINERS gpiolib: acpi: Move quirks to a separate file gpiolib: acpi: Add acpi_gpio_need_run_edge_events_on_boot() getter gpiolib: acpi: Handle deferred list via new API gpiolib: acpi: Make sure we fill struct acpi_gpio_info gpiolib: acpi: Switch to use enum in acpi_gpio_in_ignore_list() gpiolib: acpi: Use temporary variable for struct acpi_gpio_info gpiolib: remove unneeded #ifdef gpio: mpc8xxx: select GPIOLIB_IRQCHIP gpio: pxa: select GPIOLIB_IRQCHIP gpio: pxa: Make irq_chip immutable gpio: timberdale: Make irq_chip immutable gpio: xgene-sb: Make irq_chip immutable gpio: davinci: Make irq_chip immutable ...

Motivation & background: | Since commit | | c88d71508e36 ("x86/boot/64: Rewrite startup_64() in C") | | dated Jun 6 2017, we have been using C code on the boot path in a way | that is not supported by the toolchain, i.e., to execute non-PIC C | code from a mapping of memory that is different from the one provided | to the linker. It should have been obvious at the time that this was a | bad idea, given the need to sprinkle fixup_pointer() calls left and | right to manipulate global variables (including non-pointer variables) | without crashing. | | This C startup code has been expanding, and in particular, the SEV-SNP | startup code has been expanding over the past couple of years, and | grown many of these warts, where the C code needs to use special | annotations or helpers to access global objects.

2025-05-23platform/x86/intel/pmc: Fix Arrow Lake U/H NPU PCI IDTodd Brandt
The ARL requires that the GMA and NPU devices both be in D3Hot in order for PC10 and S0iX to be achieved in S2idle. The original ARL-H/U addition to the intel_pmc_core driver attempted to do this by switching them to D3 in the init and resume calls of the intel_pmc_core driver. The problem is the ARL-H/U have a different NPU device and thus are not being properly set and thus S0iX does not work properly in ARL-H/U. This patch creates a new ARL-H specific device id that is correct and also adds the D3 fixup to the suspend callback. This way if the PCI devies drop from D3 to D0 after resume they can be corrected for the next suspend. Thus there is no dropout in S0iX.

2025-05-15platform/x86/intel-uncore-freq: Add attributes to show agent typesSrinivas Pandruvada
Currently, users need detailed hardware information to understand the scope of controls within each uncore domain. Uncore frequency controls manage subsystems such as core, cache, memory, and I/O. The UFS TPMI provides this information, which can be used to present the scope more clearly. Each uncore domain consists of one or more agent types, with each agent type controlling one or more uncore hardware subsystems. For example, a single agent might control both the core and cache. Introduce a new attribute called "agent_types." This attribute displays a list of agents, separated by space character. The string representations for agent types are as follows: For core agent: core For cache agent: cache For memory agent: memory For I/O agent: io These agent types are read during probe time for each cluster and stored as part of the struct uncore_data.

2025-05-12platform/x86: dell-ddv: Implement the battery matching algorithmArmin Wolf
Since commit db0a507cb24d ("ACPICA: Update integer-to-hex-string conversions") the battery serial number is no longer distorted, allowing us to finally implement the battery matching algorithm. The battery matchign algorithm is necessary when translating between ACPI batteries and the associated indices used by the WMI interface based on the battery serial number. Since this serial number can only be retrieved when the battery is present we cannot perform the initial translation inside dell_wmi_ddv_add_battery() because the ACPI battery might be absent at this point in time. Introduce dell_wmi_ddv_battery_translate() which implements the battery matching algorithm and replaces dell_wmi_ddv_battery_index(). Also implement a translation cache for caching previous translations between ACPI batteries and indices. This is necessary because performing a translation can be very expensive.

The intent is to re-use the INT3472 code for parsing Intel camera sensor GPIOs and mapping them to the sensor for the atomisp driver, which currently has duplicate code. On atomisp devices there is no special INT3472 ACPI device, instead the Intel _DSM to get the GPIO type is part of the ACPI device for the sensor itself. To deal with this the mapping is done from ipu_bridge_init() instead of from a platform-device probe() function, there is no device to tie the lifetime of the gpiod_get() calls done by the INT3472 code to. Switch from devm_gpiod_get() to plain gpiod_get() + explicit gpiod_put() calls, to prepare for the code being re-used in the atomisp driver.

commit ba47652ba655 ("media: meye: remove this deprecated driver") removed the meye driver but left behind the code in sony-laptop.c which that driver used to call. Remove the sony_pic_camera_command() function, and the set of defines (SONY_PIC_COMMAND_*) in a header used for the interface and the static helpers it called. Cleanup remaining #defines.

2025-05-08platform/x86: ISST: Do Not Restore SST MSRs on CPU Online OperationSrinivas Pandruvada
During CPU offline/online operations, the hardware retains MSR settings. Even if all CPUs are offlined, the package does not lose its MSR settings. Therefore, it is unnecessary to restore MSRs which are modified during the online operation, and this extra step can be removed.

2025-05-08platform/x86: ISST: Support SST-PP revision 2Srinivas Pandruvada
SST PP revision 2 added fabric 1 P0, P1 and Pm frequencies. Export them by using a new IOCTL ISST_IF_GET_PERF_LEVEL_FABRIC_INFO. This IOCTL requires platforms with SST PP revision 2 or higher. To accommodate potential future increases in fabric count and avoid ABI changes, support is extended for up to 8 fabrics.

2025-05-08platform/x86: ISST: Support SST-TF revision 2Srinivas Pandruvada
SST-TF revision 2 supports a higher number of cores per bucket, as the current limit of 256 cores may be insufficient. To accommodate this, a new offset, "SST_TF_INFO-8," is introduced, allowing for a higher core count. Utilize this offset instead of the current "SST_TF_INFO-1" offset, based on SST-TF revision 2 or higher, and if there is a non-zero core count in any bucket.

2025-05-08platform/x86/tuxedo: Add virtual LampArray for TUXEDO NB04 devicesWerner Sembach
The TUXEDO Sirius 16 Gen1 and TUXEDO Sirius 16 Gen2 devices have a per-key controllable RGB keyboard backlight. The firmware API for it is implemented via WMI. To make the backlight userspace configurable this driver emulates a LampArray HID device and translates the input from hidraw to the corresponding WMI calls. This is a new approach as the leds subsystem lacks a suitable UAPI for per-key keyboard backlights, and like this no new UAPI needs to be established. The handle_* functions an corresponding structs are named based on the HID spec: HID Usage Tables 1.6 -> 26 Lighting And Illumination Page (0x59) Signed-off-by: Werner Sembach <wse@tuxedocomputers.com> Link: https://lore.kernel.org/r/20250425210043.342288-2-wse@tuxedocomputers.com Reviewed-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>
2025-05-08platform/x86: asus-wmi: Refactor Ally suspend/resumeLuke D. Jones
Adjust how the CSEE direct call hack is used. The results of months of testing combined with help from ASUS to determine the actual cause of suspend issues has resulted in this refactoring which immensely improves the reliability for devices which do not have the following minimum MCU FW version: - ROG Ally X: 313 - ROG Ally 1: 319 For MCU FW versions that match the minimum or above the CSEE hack is disabled and mcu_powersave set to on by default as there are no negatives beyond a slightly slower device reinitialization due to the MCU being powered off. As this is set only at module load time, it is still possible for mcu_powersave sysfs attributes to change it at runtime if so desired. Signed-off-by: Luke D.
