git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "We've finally gotten rid of the struct clk_ops::round_rate() code after months of effort from Brian Masney. Now the only option is to use determine_rate(), which is good because that takes a struct argument instead of just a couple unsigned longs, allowing us to easily modify the way we determine and set rates in the clk tree. Beyond that core framework change we've got the typical pile of new SoC clk driver additions, fixes for clk data and/or adding missing clks because the consumer driver using those clks wasn't ready, etc. The usual suspects are all here: Qualcomm, Samsung, Mediatek, and Rockchip along with some newcomers making RISC-V SoCs like ESWIN's eic700 and Tenstorrent's Atlantis. The clk driver side of this looks pretty normal. Core: - Remove the round_rate() clk op (yay!) New Drivers: - ESWIN eic700 SoC clk support - Econet EN751221 SoC clock/reset support - Global TCSR, RPMh, and display clock controller support for the Qualcomm Eliza platform - TCSR, the multiple global, and the RPMh clock controller support for the Qualcomm Nord platform - GPU clock controller support for Qualcomm SM8750 - Video and GPU clock controller support for Qualcomm Glymur - Global clock controller support for Qualcomm IPQ5210 - Axis ARTPEC-9: Add new PLL clocks and new drivers for eight clock controllers on the SoC - ExynosAutov920: Add G3D (GPU) clock controller - Clock driver for the Rockchip RV1103B SoC - Initial support for the Renesas RZ/G3L (R9A08G046) SoC - Clock and reset controllers (e.g. PRCM) in the Tenstorrent Atlantis SoC" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (132 commits) clk: visconti: pll: initialize clk_init_data to zero clk: fsl-sai: Add MCLK generation support clk: fsl-sai: Extract clock setup into fsl_sai_clk_register() dt-bindings: clock: fsl-sai: Document clock-cells = <1> support clk: fsl-sai: Add i.MX8M support with 8 byte register offset clk: fsl-sai: Sort the headers dt-bindings: clock: fsl-sai: Document i.MX8M support clk: qcom: gcc: Add multiple global clock controller driver for Nord SoC clk: qcom: rpmh: Add support for Nord rpmh clocks clk: qcom: Add TCSR clock driver for Nord SoC dt-bindings: clock: qcom: Add Nord Global Clock Controller dt-bindings: clock: qcom-rpmhcc: Add support for Nord SoCs dt-bindings: clock: qcom: Document the Nord SoC TCSR Clock Controller clk: qcom: gcc-x1e80100: Keep GCC USB QTB clock always ON clk: qcom: Constify list of critical CBCR registers clk: qcom: Constify qcom_cc_driver_data clk: qcom: videocc-glymur: Constify qcom_cc_desc clk: qcom: Add a driver for SM8750 GPU clocks dt-bindings: clock: qcom: Add SM8750 GPU clocks clk: qcom: ipq-cmn-pll: Add IPQ8074 SoC support ...

Several things have been reworked in GPIO core: we unduplicated GPIO hog handling, reduced the number of SRCU locks and dereferences, improved support for software-node-based lookup and removed more legacy code after converting remaining users to modern alternatives. There's also a number of driver reworks and refactoring, documentation updates, some bug-fixes and new tests. GPIO core: - defer probe on software node lookups when the remote software node exists but has not been registered as a firmware node yet - unify GPIO hog handling by moving code duplicated in OF and ACPI modules into GPIO core and allow setting up hogs with software nodes - allow matching GPIO controllers by secondary firmware node if matching by primary does not succeed - demote deferral warnings to debug level as they are quite normal when using software nodes which don't support fw_devlink yet - disable the legacy GPIO character device uAPI v1 supprt in Kconfig by default - rework several core functions in preparation for the upcoming Revocable helper library for protecting resources against sudden removal, this reduces the number of SRCU dereferences in GPIO core - simplify file descriptor logic in GPIO character device code by using FD_PREPARE() - introduce a header defining symbols used by both GPIO consumers and providers to avoid having to include provider-specific headers from drivers which only consume GPIOs - replace snprintf() with strscpy() where formatting is not required New drivers: - add the gpio-by-pinctrl generic driver using the ARM SCMI protocol to control GPIOs (along with SCMI changes pulled from the pinctrl tree) - add a driver providing support for handling of platform events via GPIO-signalled ACPI events (used on Intel Nova Lake and later platforms) Driver changes: - extend the gpio-kempld driver with support for more recent models, interrupts and setting/getting multiple values at once - improve interrupt handling in gpio-brcmstb - add support for multi-SoC systems in gpio-tegra186 - make sure we return correct values from the .get() callbacks in several GPIO drivers by normalizing any values other than 0, 1 or negative error numbers - use flexible arrays in several drivers to reduce the number of required memory allocations - simplify synchronous waiting for virtual drivers to probe and remove the dedicated, a bit overengineered helper library dev-sync-probe - remove unneeded Kconfig dependencies on OF_GPIO in several drivers and subsystems - convert the two remaining users of of_get_named_gpio() to using GPIO descriptors and remove the (no longer used) function along with the header that declares it - add missing includes in gpio-mmio - shrink and simplify code in gpio-max732x by using guard(mutex) - remove duplicated code handling the 'ngpios' property from gpio-ts4800, it's already handled in GPIO core - use correct variable type in gpio-aspeed - add support for a new model in gpio-realtek-otto - allow to specify the active-low setting of simulated hogs over the configfs interface (in addition to existing devicetree support) in gpio-sim Bug fixes: - clear the OF_POPULATED flag on hog nodes in GPIO chip remove path on OF systems - fix resource leaks in error path in gpiochip_add_data_with_key() - drop redundant device reference in gpio-mpsse Tests: - add selftests for use-after-free cases in GPIO character device code DT bindings: - add a DT binding document for SCMI based, gpio-over-pinctrl devices - fix interrupt description in microchip,mpfs-gpio - add new compatible for gpio-realtek-otto - describe the resets of the mpfs-gpio controller - fix maintainer's email in gpio-delay bindings - remove the binding document for cavium,thunder-8890 as the corresponding device is bound over PCI and not firmware nodes Documentation: - update the recommended way of converting legacy boards to using software nodes for GPIO description - describe GPIO line value semantics - misc updates to kerneldocs Misc: - convert OMAP1 ams-delta board to using GPIO hogs described with software nodes" * tag 'gpio-updates-for-v7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (79 commits) gpio: swnode: defer probe on references to unregistered software nodes dt-bindings: gpio: cavium,thunder-8890: Remove DT binding Documentation: gpio: update the preferred method for using software node lookup gpio: gpio-by-pinctrl: s/used to do/is used to do/ gpio: aspeed: fix unsigned long int declaration gpio: rockchip: convert to dynamic GPIO base allocation gpio: remove dev-sync-probe gpio: virtuser: stop using dev-sync-probe gpio: aggregator: stop using dev-sync-probe gpio: sim: stop using dev-sync-probe gpio: Add Intel Nova Lake ACPI GPIO events driver gpiolib: Make deferral warnings debug messages gpiolib: fix hogs with multiple lines gpio: fix up CONFIG_OF dependencies gpio: gpio-by-pinctrl: add pinctrl based generic GPIO driver gpio: dt-bindings: Add GPIO on top of generic pin control firmware: arm_scmi: Allow PINCTRL_REQUEST to return EOPNOTSUPP pinctrl: scmi: ignore PIN_CONFIG_PERSIST_STATE pinctrl: scmi: Delete PIN_CONFIG_OUTPUT_IMPEDANCE_OHMS support pinctrl: scmi: Add SCMI_PIN_INPUT_VALUE ...

2026-04-08Documentation: gpio: update the preferred method for using software node lookupBartosz Golaszewski
In its current version, the manual for converting of board files from using GPIO lookup tables to software nodes recommends leaving the software nodes representing GPIO controllers as "free-floating", not attached objects and relying on the matching of their names against the GPIO controller's name. This is an abuse of the software node API and makes it impossible to create fw_devlinks between GPIO suppliers and consumers in this case. We want to remove this behavior from GPIOLIB and to this end, work on converting all existing drivers to using "attached" software nodes. Except for a few corner-cases where board files define consumers depending on GPIO controllers described in firmware - where we need to reference a real firmware node from a software node - which requires a more complex approach, most board files can easily be converted to using propert firmware node lookup. Update the documentation to recommend attaching the GPIO chip's software nodes to the actual platform devices and show how to do it.

2026-04-05staging: vme_user: replace deprecated mmap hook with mmap_prepareLorenzo Stoakes (Oracle)
The f_op->mmap interface is deprecated, so update driver to use its successor, mmap_prepare. The driver previously used vm_iomap_memory(), so this change replaces it with its mmap_prepare equivalent, mmap_action_simple_ioremap(). Functions that wrap mmap() are also converted to wrap mmap_prepare() instead. Also update the documentation accordingly.

2026-03-10workqueue: devres: Add device-managed allocate workqueueKrzysztof Kozlowski
Add a Resource-managed version of alloc_workqueue() to fix common problem of drivers mixing devm() calls with destroy_workqueue. Such naive and discouraged driver approach leads to difficult to debug bugs when the driver: 1. Allocates workqueue in standard way and destroys it in driver remove() callback, 2. Sets work struct with devm_work_autocancel(), 3. Registers interrupt handler with devm_request_threaded_irq(). Which leads to following unbind/removal path: 1. destroy_workqueue() via driver remove(), Any interrupt coming now would still execute the interrupt handler, which queues work on destroyed workqueue. 2. devm_irq_release(), 3. devm_work_drop() -> cancel_work_sync() on destroyed workqueue. devm_alloc_workqueue() has two benefits: 1. Solves above problem of mix-and-match devres and non-devres code in driver, 2. Simplify any sane drivers which were correctly using alloc_workqueue() + devm_add_action_or_reset().

2026-01-26mm, arch: consolidate hugetlb CMA reservationMike Rapoport (Microsoft)
Every architecture that supports hugetlb_cma command line parameter reserves CMA areas for hugetlb during setup_arch(). This obfuscates the ordering of hugetlb CMA initialization with respect to the rest initialization of the core MM. Introduce arch_hugetlb_cma_order() callback to allow architectures report the desired order-per-bit of CMA areas and provide a week implementation of arch_hugetlb_cma_order() for architectures that don't support hugetlb with CMA. Use this callback in hugetlb_cma_reserve() instead if passing the order as parameter and call hugetlb_cma_reserve() from mm_core_init_early() rather than have it spread over architecture specific code.

2026-01-23Documentation: use a source-read extension for the index link boilerplateJani Nikula
The root document usually has a special :ref:`genindex` link to the generated index. This is also the case for Documentation/index.rst. The other index.rst files deeper in the directory hierarchy usually don't. For SPHINXDIRS builds, the root document isn't Documentation/index.rst, but some other index.rst in the hierarchy. Currently they have a ".. only::" block to add the index link when doing SPHINXDIRS html builds. This is obviously very tedious and repetitive. The link is also added to all index.rst files in the hierarchy for SPHINXDIRS builds, not just the root document. Put the boilerplate in a sphinx-includes/subproject-index.rst file, and include it at the end of the root document for subproject builds in an ad-hoc source-read extension defined in conf.py. For now, keep having the boilerplate in translations, because this approach currently doesn't cover translated index link headers.
