dt-bindings: bus: stm32mp25-rifsc: Allow 2 size cells

2026-02-04T02:58:09+00:00

There are users already with 2 size cells, and there's no reason to not support that. Reviewed-by: Gatien Chevallier Link: https://patch.msgid.link/20251215212700.3320634-1-robh@kernel.org Signed-off-by: Rob Herring (Arm)

dt-bindings: bus: aspeed: Require syscon for AST2600 AHB controller

2025-12-15T15:24:58+00:00

The AST2600's ACRY (eliptic curve and RSA crypto engine) requires access to configuration exposed by the AHB controller. The devicetree already describes the AHB controller node as a syscon, so require this in the binding to satisfy the ACRY relationship.

2025-11-14T08:46:12+00:00

The STM32MP21x platforms have a slightly different RIFSC. While its core functionalities are similar, the wiring is not the same. Hence, declare a new compatible.

Pull MFD updates from Lee Jones: "New Support & Features: - Add extensive support for the Analog Devices ADP5589 I/O expander, including core MFD, GPIO, PWM, and a new keypad matrix input driver. This also adds support for handling various events including GPI, keypad, reset and unlock ev ents - Add support for the TI TPS652G1 PMIC, a stripped-down version of the TPS65224, including core MFD, PFSM, pinctrl, and GPIO support - Add support for the Apple Silicon System Management Controller (SMC), including the core MFD driver which handles the RTKit-based protocol, a new GPIO driver for PMU GPIOs, and a new reboot/power-off driver. Improvements & Fixes: - Dynamically add ADP5585 sub-devices based on device tree properties - Move ADP5585 oscillator control from the child PWM driver to the main MFD driver to better handle shared resources - Add support for a hardware reset pin and VDD regulator to the ADP5585 driver - Update the TPS65219 MFD cell's GPIO compatible string for the TPS65214 to reflect hardware capabilities correctly - Separate the ChromeOS EC charge-control probing from the USB-PD subsystem, allowing it to probe independently based on the dedicated EC_FEATURE_CHARGER - Fix an interrupt naming typo in the MT6370 driver - Fix RK806 PMIC reset behavior by allowing the reset mode to be customized via a new device tree property - Fix AXP20X regulator cell ID conflicts for secondary PMICs on boards without an IRQ line connected - Fix MT6397 keypad sub-device creation to use specific names instead of a generic one, ensuring correct driver binding - Fix a build warning in the stm32-timers driver by adding a missing include for export.h. Cleanups & Refactoring: - Refactor the ADP5585 driver to simplify how regmap defaults are handled, making it easier to add new chip variants - Introduce per-chip register map structures for the ADP5585/ADP5589 family to handle differences between the devices - Convert several drivers to use dev_fwnode() instead of of_fwnode_handle() - Make various static structures const in the cs40l50, rohm-bd71828, tps65219, and twl6040 drivers - Remove redundant pm_runtime_mark_last_busy() calls from several drivers - Alphabetize Kconfig entries for Cirrus Logic and Maxim drivers - Remove unused fields from the 'tps65219' struct - Update several MFD-related headers to follow the 'Include What You Use' (IWYU) principle. Removals: - Remove the old, platform-data-based adp5589-keys input driver, which is now superseded by the new MFD-based adp5585-keys driver - Remove the unused twl6030_mmc_card_detect() functions and associated header declarations - Remove the now unused pcf50633/core.h header file - Remove the fsl,imx8qxp-csr device tree binding, which was being used incorrectly. Device Tree Bindings Updates: - Add support for the Analog Devices ADP5589 I/O expander to the adi,adp5585.yaml binding - Add new properties to the adi,adp5585.yaml binding for input events, including keypad pins, unlock events, and reset events - Add a reset-gpios property to the adi,adp5585.yaml binding - Add the TI TPS652G1 PMIC to the ti,tps6594.yaml binding - Add new bindings for the Apple Mac System Management Controller (SMC) and its sub-devices: apple,smc.yaml, apple,smc-gpio.yaml, and apple,smc-reboot.yaml - Convert the Freescale MXS LRADC binding (mxs-lradc) to YAML schema format - Convert and combine the NXP LPC1850 CREG, DMAMUX, and USB OTG PHY bindings into a single YAML schema file - Convert the TI TPS65910 binding to YAML schema format - Add a comment to the samsung,s2mps11.yaml binding to clarify the use of 'oneOf' for interrupt properties - Add the rockchip,reset-mode property to the rockchip,rk806.yaml binding to allow customization of the PMIC's reset behavior" * tag 'mfd-next-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd: (28 commits) mfd: dt-bindings: Convert TPS65910 to DT schema mfd: Minor Cirrus/Maxim Kconfig order fixes mfd: Remove redundant pm_runtime_mark_last_busy() calls mfd: mt6397: Do not use generic name for keypad sub-devices mfd: axp20x: Set explicit ID for regulator cell if no IRQ line is present mfd: mt6370: Fix the interrupt naming typo mfd: rk8xx-core: Allow to customize RK806 reset mode dt-bindings: mfd: rk806: Allow to customize PMIC reset mode mfd: syscon: atmel-smc: Don't use "proxy" headers mfd: madera: Don't use "proxy" headers mfd: wm8350-core: Don't use "proxy" headers dt-bindings: mfd: samsung,s2mps11: Add comment about interrupts properties mfd: davinci_voicecodec: Don't use "proxy" headers mfd: pcf50633: Remove the header file core.h mfd: tps65219: Remove another unused field from 'struct tps65219' mfd: tps65219: Remove an unused field from 'struct tps65219' mfd: tps65219: Constify struct regmap_irq_sub_irq_map and tps65219_chip_data mfd: rohm-bd71828: Constify some structures dt-bindings: mfd: fsl,imx8qxp-csr: Remove binding documentation mfd: axp20x: Set explicit ID for AXP313 regulator ...
