gpio: regmap: add the .fixed_direction_output configuration parameter

2025-10-29T13:10:32Z

[ Upstream commit 00aaae60faf554c27c95e93d47f200a93ff266ef ] There are GPIO controllers such as the one present in the LX2160ARDB QIXIS FPGA which have fixed-direction input and output GPIO lines mixed together in a single register. This cannot be modeled using the gpio-regmap as-is since there is no way to present the true direction of a GPIO line. In order to make this use case possible, add a new configuration parameter - fixed_direction_output - into the gpio_regmap_config structure. This will enable user drivers to provide a bitmap that represents the fixed direction of the GPIO lines.

treewide: rename GPIO set callbacks back to their original names

2025-08-07T08:07:06Z

The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed. Rename the new callbacks back to their original names in one sweeping change. Signed-off-by: Bartosz Golaszewski

gpio: remove legacy GPIO line value setter callbacks

2025-08-07T07:56:43Z

With no more users of the legacy GPIO line value setters - .set() and .set_multiple() - we can now remove them from the kernel. Link: https://lore.kernel.org/r/20250725074651.14002-1-brgl@bgdev.pl Signed-off-by: Bartosz Golaszewski

gpio: generic: add new generic GPIO chip API

2025-07-07T07:43:52Z

As the first step in removing the fields specific to the gpio-mmio module from struct gpio_chip, we introduce a new set of generic GPIO chip interfaces that are meant to replace the existing bgpio_ ones. The new initialization function - gpio_generic_chip_init() - takes a configuration structure as argument instead of 9 separate parameters. This will allow easy extension if needed in the future. We hide the locking details behind a set of helpers in order to be able to move the raw spinlock out of struct gpio_chip without the users noticing. For now, the new APIs just wrap the existing ones. Once all users have been converted to the new interfaces, we'll pull them into gpio-mmio and implement them in a backward-compatible way while also moving all fields specific to the generic GPIO chip into struct gpio_generic_chip.

With no more users, we can now remove struct bgpio_pdata. Move the relevant bits from bgpio_parse_fw() into bgpio_pdev_probe() while maintaining the logical ordering (get flags before calling bgpio_init()).

gpio: mmio: add BGPIOF_NO_INPUT flag for GPO gpiochip

2025-06-19T07:05:33Z

When using bgpio_init with a gpiochip acting as a GPO (output only), the gpiochip ops `direction_input` was set to `bgpio_simple_dir_in` by default but we have no input ability. Adding this flag allows to set a valid ops for the `direction_output` ops without setting a valid ops for `direction_input` by default.

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 ...
