b4918003cf 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"

3d6a17fccc dt-bindings: mfd: Move embedded controllers to own directory 
Move several embedded controller bindings (like ChromeOS EC, Gateworks
System Controller and Kontron sl28cpld Board Management) to new
subdirectory "embedded-controller" matching their purpose.

An embedded controller (EC) is a discrete component that contains a
microcontroller (i.e. a small CPU running a small firmware without
operating system) mounted into a larger computer system running
a fully fledged operating system that needs to utilize the embedded
controller as part of its operation.

So far the EC bindings were split between "mfd" and "platform"
directory.  MFD name comes from Linux, not hardware, and "platform" is a
bit too generic.

Rename Gateworks GSC and Huawei Gaokun filenames to match compatible, as
preferred for bindings.

71d689f60b dt-bindings: hwmon: isl68137: add bindings to support voltage dividers 
Add devicetree bindings to support declaring optional voltage dividers to
the rail outputs of supported digital multiphase regulators. Some
applications require Vout to exceed the voltage range that the Vsense pin
can detect. This binding definition allows users to define the
characteristics of a voltage divider placed between Vout and the Vsense
pin for any rail powered by the device.

These bindings copy the vout-voltage-divider property defined in the
maxim,max20730 bindings schema since it is the best fit for the use case
of scaling hwmon PMBus telemetry. The generic voltage-divider property
used by many iio drivers was determined to be a poor fit because that
schema is tied directly to iio for the purpose of scaling io-channel
voltages and the isl68137 driver is not an iio driver.

New schema file named isil,isl68137.yaml to align with the corresponding
driver name and pre-existing bindings ported from trivial bindings.
However, all new device bindings use renesas as the vendor prefix
since Renesas acquired Intersil and now maintains all documentation
for the devices.

80bc64201e dt-bindings: hwmon: pwm-fan: Document start from stopped state properties 
Delta AFC0612DB-F00 fan has to be set to at least 30% PWM duty cycle
to spin up from a stopped state, and can be afterward throttled down to
lower PWM duty cycle. Introduce support for operating such fans which
need to start at higher PWM duty cycle first and can slow down next.

Document two new DT properties, "fan-stop-to-start-percent" and
"fan-stop-to-start-usec". The former describes the minimum percent
of fan RPM at which it will surely spin up from stopped state. This
value can be found in the fan datasheet and can be converted to PWM
duty cycle easily. The "fan-stop-to-start-usec" describes the minimum
time in microseconds for which the fan has to be set to stopped state
start RPM for the fan to surely spin up.
