2025-10-01T19:04:12Z

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. Device Tree Bindings Updates: - Add device tree bindings for the TI BQ25703A charger" * tag 'mfd-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd: (69 commits) mfd: simple-mfd-i2c: Add compatible string for LX2160ARDB mfd: simple-mfd-i2c: Keep compatible strings in alphabetical order dt-bindings: mfd: twl: Add missing sub-nodes for TWL4030 & TWL603x dt-bindings: watchdog: Add SMARC-sAM67 support dt-bindings: mfd: tps6594: Allow gpio-line-names mfd: intel-lpss: Add Intel Wildcat Lake LPSS PCI IDs mfd: 88pm886: Add GPADC cell mfd: vexpress-sysreg: Use more common syntax for compound literals mfd: rz-mtu3: Fix MTU5 NFCR register offset mfd: max77705: Setup the core driver as an interrupt controller mfd: cs42l43: Remove IRQ masking in suspend mfd: cs42l43: Move IRQ enable/disable to encompass force suspend mfd: ls2kbmc: Add Loongson-2K BMC reset function support mfd: ls2kbmc: Introduce Loongson-2K BMC core driver mfd: bd71828, bd71815: Prepare for power-supply support dt-bindings: mfd: aspeed: Add AST2700 SCU compatibles dt-bindings: mfd: Convert aspeed,ast2400-p2a-ctrl to DT schema dt-bindings: mfd: fsl,mc13xxx: Add buttons node dt-bindings: mfd: fsl,mc13xxx: Convert txt to DT schema mfd: macsmc: Add "apple,t8103-smc" compatible ...

driver: reset: th1520-aon: add driver for poweroff/reboot via AON FW

2025-09-19T10:55:20Z

This driver implements poweroff/reboot support for T-Head TH1520 SoCs running the AON firmware by sending a message to the AON firmware's WDG part. This is a auxiliary device driver, and expects the AON channel to be passed via the platform_data of the auxiliary device.

power: supply: qcom_battmgr: handle charging state change notifications

2025-09-19T10:35:57Z

The X1E80100 battery management firmware sends a notification with code 0x83 when the battery charging state changes, such as switching between fast charge, taper charge, end of charge, or any other error charging states. The same notification code is used with bit[8] set when charging stops because the charge control end threshold is reached. Additionally, a 2-bit value is included in bit[10:9] with the same code to indicate the charging source capability, which is determined by the calculated power from voltage and current readings from PDOs: 2 means a strong charger over 60W, 1 indicates a weak charger, and 0 means there is no charging source. These 3-MSB [10:8] in the notification code is not much useful for now, hence just ignore them and trigger a power supply change event whenever 0x83 notification code is received. This helps to eliminate the unknown notification error messages.

2025-09-18T22:40:03Z

Current implementation uses handle_post_irq to actually handle chgin irq. This is not how things are meant to work in regmap-irq. Remove handle_post_irq, and request a threaded interrupt for chgin.
