git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio updates from Bartosz Golaszewski: "There are two new drivers and support for more models in existing ones. The generic GPIO API has been reworked and all users converted which allowed us to move the fields specific to the generic GPIO implementation out of the high-level struct gpio_chip into its own structure that wraps the gpio_chip. Other than that, there's nothing too exciting. Mostly minor tweaks and fixes all over the place, some refactoring and some small new features in helper modules. GPIO core: - add support for sparse pin ranges to the glue between GPIO and pinctrl - use a common prefix across all GPIO descriptor flags for improved namespacing New drivers: - add new GPIO driver for the Nuvoton NCT6694 - add new GPIO driver for MAX7360 Driver improvements: - add support for Tegra 256 to the gpio-tegra186 driver - add support for Loongson-2K0300 to the gpio-loongson-64bit driver - refactor the gpio-aggregator module to expose its GPIO forwarder API to other in-kernel users (to enable merging of a new pinctrl driver that uses it) - convert all remaining drivers to using the modernized generic GPIO chip API and remove the old interface - stop displaying global GPIO numbers in debugfs output of controller drivers - extend the gpio-regmap helper with a new config option and improve its support for GPIO interrupts - remove redundant fast_io parameter from regmap configs in GPIO drivers that already use MMIO regmaps which imply it - add support for a new model in gpio-mmio: ixp4xx expansion bus - order includes alphabetically in a few drivers for better readability - use generic device properties where applicable - use devm_mutex_init() where applicable - extend build coverage of drivers by enabling more to be compiled with COMPILE_TEST enabled - allow building gpio-stmpe as a module - use dev_err_probe() where it makes sense in drivers Late driver fixes: - fix setting GPIO direction to output in gpio-mpfs Documentation: - document the usage of software nodes with GPIO chips Device-tree bindings: - Add DT bindings documents for new hardware: Tegra256, MAX7360 - Document a new model in Loongson bindings: LS2K0300 - Document a new model using the generic GPIO binding: IXP4xx - Convert the DT binding for fsl,mxs-pinctrl to YAML - fix the schema ID in the "trivial" GPIO schema - describe GPIO hogs in the generic GPIO binding" * tag 'gpio-updates-for-v6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (122 commits) gpio: mpfs: fix setting gpio direction to output gpio: generic: move GPIO_GENERIC_ flags to the correct header gpio: generic: rename BGPIOF_ flags to GPIO_GENERIC_ gpio: nomadik: fix the debugfs helper stub MAINTAINERS: Add entry on MAX7360 driver input: misc: Add support for MAX7360 rotary input: keyboard: Add support for MAX7360 keypad gpio: max7360: Add MAX7360 gpio support gpio: regmap: Allow to provide init_valid_mask callback gpio: regmap: Allow to allocate regmap-irq device pwm: max7360: Add MAX7360 PWM support pinctrl: Add MAX7360 pinctrl driver mfd: Add max7360 support dt-bindings: mfd: gpio: Add MAX7360 rtc: Add Nuvoton NCT6694 RTC support hwmon: Add Nuvoton NCT6694 HWMON support watchdog: Add Nuvoton NCT6694 WDT support can: Add Nuvoton NCT6694 CANFD support i2c: Add Nuvoton NCT6694 I2C support gpio: Add Nuvoton NCT6694 GPIO support ...

2025-09-14Input: cros_ec_keyb - Defer probe until parent EC device is registeredTzung-Bi Shih1-0/+6
The `cros_ec_keyb` driver can be probed before the cros_ec_device has completed the registration. This creates a race condition where `cros_ec_keyb` might access uninitialized data. Fix this by calling `cros_ec_device_registered()` to check the parent's status. If the device is not yet ready, return -EPROBE_DEFER to ensure the probe is retried later.

Support for MT6359 PMIC keys has been added recently. However, the key release event is not properly handled: only key press events are generated, leaving key states stuck in "pressed". This patch ensures that both key press and key release events are properly emitted by handling the release logic correctly. Introduce a 'key_release_irq' member to the 'mtk_pmic_regs' to identify the devices that have a separate irq for the release event.

2025-07-27Input: atkbd - correctly map F13 - F24Werner Sembach1-6/+6
Currently only F23 is correctly mapped for PS/2 keyboards. According to this table: https://download.microsoft.com/download/1/6/1/161ba512-40e2-4cc9-843a-923143f3456c/translate.pdf - F24 and Zenkaku/Hankaku share the same scancode, but since in real world Zenkaku/Hankaku keys seem to just use the tilde scancode, this patch binds the scancode to F24. Note that on userspace side the KEY_ZENKAKUHANKAKU keycode is currently not bound in xkeyboard-config, so it is (mostly*) unused anyway. * Qt on Wayland and therefore KDE on Wayland can see the keypress anyway for some reason and it is actually used in a touchpad toggle shortcut, but this is currently being fixed in both KDE and xkeyboard-config to make this less weird, so it could directly be fixed to correctly handle the F24 keypress instead. - The scancodes for F13-F22 are currently unmapped so there will probably be no harm in mapping them. This would also fix the issue that some of these keys can't be mapped as the target from userspace using the `setkeycodes` command.

2025-04-29Input: mtk-pmic-keys - fix possible null pointer dereferenceGary Bisson1-2/+2
In mtk_pmic_keys_probe, the regs parameter is only set if the button is parsed in the device tree. However, on hardware where the button is left floating, that node will most likely be removed not to enable that input. In that case the code will try to dereference a null pointer. Let's use the regs struct instead as it is defined for all supported platforms. Note that it is ok setting the key reg even if that latter is disabled as the interrupt won't be enabled anyway.

2025-04-09Input: matrix_keypad - detect change during scanMarkus Burri1-0/+16
For a setup where the matrix keypad is connected over a slow interface (e.g. a gpio-expansion over i2c), the scan can take a longer time to read. Interrupts need to be disabled during scan. And therefore changes in this period are not detected. To improve this situation, scan the matrix again if the row state changed during interrupts disabled. The rescan is repeated until no change is detected anymore.
