The most notable additions include new drivers for Loongson's Security Engine, RNG and TPM, new drivers for TI's TPS6594 Power Button and BQ257xx Charger ICs. The rest of the set provides a return value check fix and a refactoring to use a more modern GPIO API for the VEXPRESS sysreg driver, the removal of a deprecated IRQ ACK function from the MC13xxx RTC driver and a new DT binding for the aforementioned TI BQ257xx charger. New Support & Features: - Add a suite of drivers for the Loongson Security Engine, including the core controller, a Random Number Generator (RNG) and Trusted Platform Module (TPM) support. - Introduce support for the TI TPS6594 PMIC's power button, including the input driver, MFD cell registration, and a system power-off handler. - Add comprehensive support for the TI BQ257xx series of charger ICs, including the core MFD driver and a power supply driver for the charger functionality. Improvements & Fixes: - Check the return value of devm_gpiochip_add_data() in the VEXPRESS sysreg driver to prevent potential silent failures. Cleanups & Refactoring: - Add a MAINTAINERS entry for the new Loongson Security Engine drivers. - Convert the VEXPRESS sysreg driver to use the modern generic GPIO chip API. Removals: - Remove the deprecated and unused mc13xxx_irq_ack() function from the MC13xxx RTC, input and touchscreen drivers.

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 ... 2025-10-01T09:27:35+00:00 Lee Jones lee@kernel.org 2025-10-01T09:27:35+00:00 urn:sha1:e8c81284032ad9ba9ec3a89311c587aad0c84beb 2025-09-30T20:19:53+00:00 Dan Carpenter dan.carpenter@linaro.org 2025-09-30T12:25:33+00:00 urn:sha1:d655a684c24dde9e9f3f98f3dbae5a4f592117d4 Fix this copy and paste bug.

On the other hand, pwrkey should keep wakeup on. So do not enable wakeup for resin unless the "wakeup-source" property is specified in devicetree. Note, that this does change behavior by turning off wakeup by default for 'resin' and requiring a new dt property to be added to turn it on again. But since this is not expected behavior in the first place, and most users will not expect this, I'd argue this change is acceptable.
