Pull irq updates from Thomas Gleixner: "The interrupt departement provides: - A mechanism to shield isolated tasks from managed interrupts: The affinity of managed interrupts is completely controlled by the kernel and user space has no influence on them. The reason is that the automatically assigned affinity correlates to the multi-queue CPU handling of block devices. If the generated affinity mask spaws both housekeeping and isolated CPUs the interrupt could be routed to an isolated CPU which would then be disturbed by I/O submitted by a housekeeping CPU. The new mechamism ensures that as long as one housekeeping CPU is online in the assigned affinity mask the interrupt is routed to a housekeeping CPU. If there is no online housekeeping CPU in the affinity mask, then the interrupt is routed to an isolated CPU to keep the device queue intact, but unless the isolated CPU submits I/O by itself these interrupts are not raised. - A small addon to the device tree irqdomain core code to avoid duplication in irq chip drivers - Conversion of the SiFive PLIC to hierarchical domains - The usual pile of new irq chip drivers: SiFive GPIO, Aspeed SCI, NXP INTMUX, Meson A1 GPIO - The first cut of support for the new ARM GICv4.1 - The usual pile of fixes and improvements in core and driver code" * tag 'irq-core-2020-01-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (33 commits) genirq, sched/isolation: Isolate from handling managed interrupts irqchip/gic-v4.1: Allow direct invalidation of VLPIs irqchip/gic-v4.1: Suppress per-VLPI doorbell irqchip/gic-v4.1: Add VPE INVALL callback irqchip/gic-v4.1: Add VPE eviction callback irqchip/gic-v4.1: Add VPE residency callback irqchip/gic-v4.1: Add mask/unmask doorbell callbacks irqchip/gic-v4.1: Plumb skeletal VPE irqchip irqchip/gic-v4.1: Implement the v4.1 flavour of VMOVP irqchip/gic-v4.1: Don't use the VPE proxy if RVPEID is set irqchip/gic-v4.1: Implement the v4.1 flavour of VMAPP irqchip/gic-v4.1: VPE table (aka GICR_VPROPBASER) allocation irqchip/gic-v3: Add GICv4.1 VPEID size discovery irqchip/gic-v3: Detect GICv4.1 supporting RVPEID irqchip/gic-v3-its: Fix get_vlpi_map() breakage with doorbells irqdomain: Fix a memory leak in irq_domain_push_irq() irqchip: Add NXP INTMUX interrupt multiplexer support dt-bindings: interrupt-controller: Add binding for NXP INTMUX interrupt multiplexer irqchip: Define EXYNOS_IRQ_COMBINER irqchip/meson-gpio: Add support for meson a1 SoCs ...

2020-01-07gpiolib: acpi: Add honor_wakeup module-option + quirk mechanismHans de Goede1-1/+31
On some laptops enabling wakeup on the GPIO interrupts used for ACPI _AEI event handling causes spurious wakeups. This commit adds a new honor_wakeup option, defaulting to true (our current behavior), which can be used to disable wakeup on troublesome hardware to avoid these spurious wakeups. This is a workaround for an architectural problem with s2idle under Linux where we do not have any mechanism to immediately go back to sleep after wakeup events, other then for embedded-controller events using the standard ACPI EC interface, for details see: https://lore.kernel.org/linux-acpi/61450f9b-cbc6-0c09-8b3a-aff6bf9a0b3c@redhat.com/ One series of laptops which is not able to suspend without this workaround is the HP x2 10 Cherry Trail models, this commit adds a DMI based quirk which makes sets honor_wakeup to false on these models.

2019-12-11gpiolib: fix up emulated open drain outputsRussell King1-0/+8
gpiolib has a corner case with open drain outputs that are emulated.

This is different from the behaviour with a true open-drain output. Unify the semantics here.

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v5.5 kernel cycle Core changes: - Expose pull up/down flags for the GPIO character device to userspace. After clear input from the RaspberryPi and Beagle communities, it has been established that prototyping, industrial automation and make communities strongly need this feature, and as we want people to use the character device, we have implemented the simple pull up/down interface for GPIO lines. This means we can specify that a (chip-specific) pull up/down resistor can be enabled, but does not offer fine-grained control such as cases where the resistance of the same pull resistor can be controlled (yet). - Introduce devm_fwnode_gpiod_get_index() and start to phase out the old symbol devm_fwnode_get_index_gpiod_from_child(). - A bit of documentation clean-up work. - Introduce a define for GPIO line directions and deploy it in all GPIO drivers in the drivers/gpio directory. - Add a special callback to populate pin ranges when cooperating with the pin control subsystem and registering ranges as part of adding a gpiolib driver and a gpio_irq_chip driver at the same time. This is also deployed in the Intel Merrifield driver. New drivers: - RDA Micro GPIO controller. - XGS-iproc GPIO driver. Driver improvements: - Wake event and debounce support on the Tegra 186 driver. - Finalize the Aspeed SGPIO driver. - MPC8xxx uses a normal IRQ handler rather than a chained handler" * tag 'gpio-v5.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (64 commits) gpio: Add TODO item for regmap helper Documentation: gpio: driver.rst: Fix warnings gpio: of: Fix bogus reference to gpiod_get_count() gpiolib: Grammar s/manager/managed/ gpio: lynxpoint: Setup correct IRQ handlers MAINTAINERS: Replace my email by one @kernel.org gpiolib: acpi: Make acpi_gpiochip_alloc_event always return AE_OK gpio/mpc8xxx: fix qoriq GPIO reading gpio: mpc8xxx: Don't overwrite default irq_set_type callback gpiolib: acpi: Print pin number on acpi_gpiochip_alloc_event errors gpiolib: fix coding style in gpiod_hog() drm/bridge: ti-tfp410: switch to using fwnode_gpiod_get_index() gpio: merrifield: Pass irqchip when adding gpiochip gpio: merrifield: Add GPIO <-> pin mapping ranges via callback gpiolib: Introduce ->add_pin_ranges() callback gpio: mmio: remove untrue leftover comment gpio: em: Use platform_get_irq() to obtain interrupts gpio: tegra186: Add debounce support gpio: tegra186: Program interrupt route mapping gpio: tegra186: Derive register offsets from bank/port ...
2019-11-28gpio: Handle counting of Freescale chipselectsLinus Walleij1-0/+27
We have a special quirk to handle the Freescale nonstandard SPI chipselect GPIOs in the gpiolib-of.c file, but it currently only handles the case where the GPIOs are actually requested (gpiod_*get()). We also need to handle that the SPI core attempts to count the GPIOs before use, and that needs a similar quirk in the OF part of the library.

Pull driver core updates from Greg KH: "Here is the "big" set of driver core patches for 5.5-rc1 There's a few minor cleanups and fixes in here, but the majority of the patches in here fall into two buckets: - debugfs api cleanups and fixes - driver core device link support for boot dependancy issues The debugfs api cleanups are working to slowly refactor the debugfs apis so that it is even harder to use incorrectly. That work has been happening for the past few kernel releases and will continue over time, it's a long-term project/goal The driver core device link support missed 5.4 by just a bit, so it's been sitting and baking for many months now. It's from Saravana Kannan to help resolve the problems that DT-based systems have at boot time with dependancy graphs and kernel modules. Turns out that no one has actually tried to build a generic arm64 kernel with loads of modules and have it "just work" for a variety of platforms (like a distro kernel). The big problem turned out to be a lack of dependency information between different areas of DT entries, and the work here resolves that problem and now allows devices to boot properly, and quicker than a monolith kernel.

Pull MIPS updates from Paul Burton: "The main MIPS changes for 5.5: - Atomics-related code sees some rework & cleanup, most notably allowing Loongson LL/SC errata workarounds to be more bulletproof & their correctness to be checked at build time. - Command line setup code is simplified somewhat, resolving various corner cases. - MIPS kernels can now be built with kcov code coverage support. - We can now build with CONFIG_FORTIFY_SOURCE=y. - Miscellaneous cleanups. And some platform specific changes: - We now disable some broken TLB functionality on certain Ingenic systems, and JZ4780 systems gain some devicetree nodes to support more devices. - Loongson support sees a number of cleanups, and we gain initial support for Loongson 3A R4 systems. - We gain support for MediaTek MT7688-based GARDENA Smart Gateway systems. - SGI IP27 (Origin 2*) see a number of fixes, cleanups & simplifications. - SGI IP30 (Octane) systems are now supported" * tag 'mips_5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (107 commits) MIPS: SGI-IP27: Enable ethernet phy on second Origin 200 module MIPS: PCI: Fix fake subdevice ID for IOC3 MIPS: Ingenic: Disable abandoned HPTLB function.
