Linus Torvalds 24e5c3241a MFD for v6.17
- New Support & Features
   * Add extensive support for the Analog Devices ADP5589 I/O expander, including
     core MFD, GPIO, PWM, and a new keypad matrix input driver. This also adds
     support for handling various events including GPI, keypad, reset and unlock
     ev ents.
   * Add support for the TI TPS652G1 PMIC, a stripped-down version of the TPS65224,
     including core MFD, PFSM, pinctrl, and GPIO support.
   * Add support for the Apple Silicon System Management Controller (SMC), including
     the core MFD driver which handles the RTKit-based protocol, a new GPIO driver
     for PMU GPIOs, and a new reboot/power-off driver.
 
 - Improvements & Fixes
   * Dynamically add ADP5585 sub-devices based on device tree properties.
   * Move ADP5585 oscillator control from the child PWM driver to the main MFD
     driver to better handle shared resources.
   * Add support for a hardware reset pin and VDD regulator to the ADP5585 driver.
   * Update the TPS65219 MFD cell's GPIO compatible string for the TPS65214 to
     reflect hardware capabilities correctly.
   * Separate the ChromeOS EC charge-control probing from the USB-PD subsystem,
     allowing it to probe independently based on the dedicated EC_FEATURE_CHARGER.
   * Fix an interrupt naming typo in the MT6370 driver.
   * Fix RK806 PMIC reset behavior by allowing the reset mode to be customized via a
     new device tree property.
   * Fix AXP20X regulator cell ID conflicts for secondary PMICs on boards without an
     IRQ line connected.
   * Fix MT6397 keypad sub-device creation to use specific names instead of a
     generic one, ensuring correct driver binding.
   * Fix a build warning in the stm32-timers driver by adding a missing include for
     export.h.
 
 - Cleanups & Refactoring
   * Refactor the ADP5585 driver to simplify how regmap defaults are handled, making
     it easier to add new chip variants.
   * Introduce per-chip register map structures for the ADP5585/ADP5589 family to
     handle differences between the devices.
   * Convert several drivers to use dev_fwnode() instead of of_fwnode_handle().
   * Make various static structures const in the cs40l50, rohm-bd71828, tps65219,
     and twl6040 drivers.
   * Remove redundant pm_runtime_mark_last_busy() calls from several drivers.
   * Alphabetize Kconfig entries for Cirrus Logic and Maxim drivers.
   * Remove unused fields from the 'tps65219' struct.
   * Update several MFD-related headers to follow the 'Include What You Use' (IWYU)
     principle.
 
 - Removals
   * Remove the old, platform-data-based adp5589-keys input driver, which is now
     superseded by the new MFD-based adp5585-keys driver.
   * Remove the unused twl6030_mmc_card_detect() functions and associated header
     declarations.
   * Remove the now unused pcf50633/core.h header file.
   * Remove the fsl,imx8qxp-csr device tree binding, which was being used
     incorrectly.
 
 - Device Tree Bindings Updates
   * Add support for the Analog Devices ADP5589 I/O expander to the adi,adp5585.yaml
     binding.
   * Add new properties to the adi,adp5585.yaml binding for input events, including
     keypad pins, unlock events, and reset events.
   * Add a reset-gpios property to the adi,adp5585.yaml binding.
   * Add the TI TPS652G1 PMIC to the ti,tps6594.yaml binding.
   * Add new bindings for the Apple Mac System Management Controller (SMC) and its
     sub-devices: apple,smc.yaml, apple,smc-gpio.yaml, and apple,smc-reboot.yaml.
   * Convert the Freescale MXS LRADC binding (mxs-lradc) to YAML schema format.
   * Convert and combine the NXP LPC1850 CREG, DMAMUX, and USB OTG PHY bindings into
     a single YAML schema file.
   * Convert the TI TPS65910 binding to YAML schema format.
   * Add a comment to the samsung,s2mps11.yaml binding to clarify the use of 'oneOf'
     for interrupt properties.
   * Add the rockchip,reset-mode property to the rockchip,rk806.yaml binding to
     allow customization of the PMIC's reset behavior.

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.
