Linus Torvalds b4918003cf 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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
