2025-06-20gpio: sysfs: remove the mockdev pointer from struct gpio_deviceBartosz Golaszewski
The usage of the mockdev pointer in struct gpio_device is limited to the GPIO sysfs code. There's no reason to keep it in this top-level structure. Create a separate structure containing the reference to the GPIO device and the dummy class device that will be passed to device_create_with_groups(). The !gdev->mockdev checks can be removed as long as we make sure that all operations on the GPIO class are protected with the sysfs lock.

2025-06-09gpiolib: acpi: Add a quirk for Acer Nitro V15Mario Limonciello
It is reported that on Acer Nitro V15 suspend only works properly if the keyboard backlight is turned off. In looking through the issue Acer Nitro V15 has a GPIO (#8) specified in _AEI but it has no matching notify device in _EVT. The values for GPIO #8 change as keyboard backlight is turned on and off. This makes it seem that GPIO #8 is actually supposed to be solely for keyboard backlight. Turning off the interrupt for this GPIO fixes the issue. Add a quirk that does just that.

git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio updates from Bartosz Golaszewski: "We have three new drivers, some refactoring in the GPIO core, lots of various changes across many drivers, new configfs interface for the virtual gpio-aggregator module and DT-bindings updates. The treewide conversion of GPIO drivers to using the new value setter callbacks is ongoing with another round of GPIO drivers updated. 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 ...
