Merge tag 'mfd-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd

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"
