Pull SoC driver updates from Arnd Bergmann: "Lots of platform specific updates for Qualcomm SoCs, including a new TEE subsystem driver for the Qualcomm QTEE firmware interface. Added support for the Apple A11 SoC in drivers that are shared with the M1/M2 series, among more updates for those. Smaller platform specific driver updates for Renesas, ASpeed, Broadcom, Nvidia, Mediatek, Amlogic, TI, Allwinner, and Freescale SoCs. Driver updates in the cache controller, memory controller and reset controller subsystems. SCMI firmware updates to add more features and improve robustness. This includes support for having multiple SCMI providers in a single system. TEE subsystem support for protected DMA-bufs, allowing hardware to access memory areas that managed by the kernel but remain inaccessible from the CPU in EL1/EL0" * tag 'soc-drivers-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (139 commits) soc/fsl/qbman: Use for_each_online_cpu() instead of for_each_cpu() soc: fsl: qe: Drop legacy-of-mm-gpiochip.h header from GPIO driver soc: fsl: qe: Change GPIO driver to a proper platform driver tee: fix register_shm_helper() pmdomain: apple: Add "apple,t8103-pmgr-pwrstate" dt-bindings: spmi: Add Apple A11 and T2 compatible serial: qcom-geni: Load UART qup Firmware from linux side spi: geni-qcom: Load spi qup Firmware from linux side i2c: qcom-geni: Load i2c qup Firmware from linux side soc: qcom: geni-se: Add support to load QUP SE Firmware via Linux subsystem soc: qcom: geni-se: Cleanup register defines and update copyright dt-bindings: qcom: se-common: Add QUP Peripheral-specific properties for I2C, SPI, and SERIAL bus Documentation: tee: Add Qualcomm TEE driver tee: qcom: enable TEE_IOC_SHM_ALLOC ioctl tee: qcom: add primordial object tee: add Qualcomm TEE driver tee: increase TEE_MAX_ARG_SIZE to 4096 tee: add TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF tee: add TEE_IOCTL_PARAM_ATTR_TYPE_UBUF tee: add close_context to TEE driver operation ...

Pull MFD updates from Lee Jones: "This round of updates contains a fair amount of new device support, a couple of fixes and some refactoring. 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.

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 ...
