Subject: [GIT PULL] MFD for v6.18
Good afternoon Linus,
The following changes since commit 8f5ae30d69d7543eee0d70083daf4de8fe15d585:
Linux 6.17-rc1 (2025-08-10 19:41:16 +0300)
are available in the Git repository at:

mfd: simple-mfd-i2c: Add compatible string for LX2160ARDB (2025-10-01 10:46:00 +0100)
----------------------------------------------------------------
MFD for v6.18
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.
