c2b148f3bc mfd: Add support for AAEON UP board FPGA 
The UP boards implement some features (pin controller, LEDs) through an
on-board FPGA.

This MFD driver implements the line protocol to communicate with the FPGA
through regmap, and registers pin controller and led cells.

This commit adds support for UP and UP Squared boards.

Based on the work done by Gary Wang <garywang@aaeon.com.tw>.

998f70d180 mfd: Add base driver for qnap-mcu devices 
These microcontroller units are used in network-attached-storage devices
made by QNAP and provide additional functionality to the system.

This adds the base driver that implements the serial protocol via
serdev and additionally hooks into the poweroff handlers to turn
off the parts of the system not supplied by the general PMIC.

Turning off (at least the TSx33 devices using Rockchip SoCs) consists of
two separate actions. Turning off the MCU alone does not turn off the main
SoC and turning off only the SoC/PMIC does not turn off the hard-drives.
Also if the MCU is not turned off, the system also won't start again until
it is unplugged from power.

So on shutdown the MCU needs to be turned off separately before the
main PMIC.

The protocol spoken by the MCU is sadly not documented, but was
obtained by listening to the chatter on the serial port, as thankfully
the "hal_app" program from QNAPs firmware allows triggering all/most
MCU actions from the command line.

The implementation of how to talk to the serial device got some
inspiration from the rave-sp servdev driver.

fa52c04dae mfd: core: Make platform_data pointer const in struct mfd_cell 
The content of the platform_data of a struct mfd_cell is simply passed on
to the platform_device_add_data() call in mfd_add_device() .

platform_device_add_data() already handles the data behind that pointer
as const and also uses kmemdup to create a copy of the data before
handing that copy over to the newly created platform-device,
so there is no reason to not extend this to struct mfd_cell, as the old
copy in the mfd_cell will be stale anyway.

This allows to pass structs gathered from of_device_get_match_data()
as platform-data to sub-devices - which is retrieved as const already.

131561f2ca gpio updates for v6.13-rc1 
GPIOLIB core:
 - use the new mem_is_zero() instead of memchr_inv(s, 0, n)
 - don't store debounce period twice needlessly
 - clean-up debugfs handling
 - remove leftover comments referring to no longer used spinlocks
 - unduplicate some operations like SRCU locks and initializing GPIO descriptors
 - constify the sysfs class struct
 - use lock guards in GPIO sysfs code
 - update GPIO uAPI internal flags all at once atomically for consistency with
   other places
 - modify the behavior of the sysfs interface by no longer exporting lines that
   are named inside the driver code or board files with the sysfs links bearing
   the line names as this has for many years been largely unused due to the
   prevalence of DT, ACPI and firmware nodes over board files and made the API
   inconsistent
 - for GPIO interrupt providers: free irqs that are still requested by users
   when removing the chip
 
 GPIO uAPI:
 - notify user-space about changes to GPIO lines' state (requested, released,
   reconfigured) triggered from the kernel as well (until now we'd only do
   this for changes triggered from user-space)
 - to that end: modify the internal workings of the notification mechanism by
   switching to an atomic notifier which allows us to send events from atomic
   context
 - also to that end store the debounce period in the GPIO descriptor struct
   and not in the character device context struct
 - while at it, also cover the corner-case of users introducing changes over
   sysfs while others watch them via the character device
 - don't report GPIO lines requested as interrupts as "used" to user-space as it
   can still request them as GPIOs
 
 New drivers:
 - add a driver for the GPIO functionality of the MFD Congatec Board Controller
 - add a driver for the PolarFire GPIO controller
 - add a driver supporting the GPIOs on FTDI FT2232H
 
 Driver improvements:
 - use generic device property accessors instead of OF-specific ones across
   many GPIO drivers (mpc8xxx, vf610, eic-sprd, davinci, ts4900, xilinx, mvebu)
 - use devres helpers to simplify error paths and either shrink or entirely
   remove the driver's remove() callback (grgpio, amdpt, menz127, max730x,
   ftgpio010, 74x164, ljca)
 - use helper variables to store the address of pdev->dev and avoid some
   line-breaks
 - use device_for_each_child_node_scoped() to avoid having to put the fwnode
   on breaks or errors (gpio-sim, gpio-dwapb, gpiolib-acpi)
 - use a scoped bitmap to simplify the code and drop goto labels in
   gpio-aggregator
 - drop unneeded Kconfig dependencies on OF_GPIO (grgpio, mveby, xilinx)
 - add support for new models to gpio-aspeed, gpio-rockchip and gpio-dwapb
 - clean-up ACPI handling and some other bits in gpio-xgene-sb
 - replace deprecated PCI functions in pcie-idio-24 and pci-idio-16
 - allow to build davinci and mvebu drivers with COMPILE_TEST=y
 - remove dead code in gpio-mb86s7x
 - switch back to using platform_driver::remove() (after the conversion to
   remove_new()) across the GPIO drivers
 - remove remaining uses of GPIOF_ACTIVE_LOW across the tree and drop this
   deprecated symbol
 - convert the gpio-altera driver to no longer pull in the deprecated
   legacy-of-mm-gpiochip.h header
 - use of_property_present() instead of of_property_read_bool() in gpiolib-of
   and gpio-rockchip
 - allow to build the tegra186 driver on Tegra234 platforms in Kconfig
 
 Late fixes:
 - add a missing return value check after devm_kasprintf() to gpio-grgpio
 
 DT bindings:
 - document the ngpios property of gpio-mmio
 - add support for a new aspeed model
 - fix the example for st,nomadik-gpio
 
 Other:
 - kernel doc and comments tweaks
 - fix typos in TODO
 - reorder headers alphabetically in some drivers

Merge tag 'gpio-updates-for-v6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "Three new drivers, support for some new models in existing ones and
  lots of various tweaks and improvements across the board (switching to
  using recommended APIs, code shrink and simplification, etc.).

  Also a new feature in the character device uAPI where we now notify
  the user-space about changes triggered by in-kernel users as well, not
  only when they were done by other user-space agents.

35fec94afe mfd: axp20x: Add support for AXP323 
The X-Powers AXP323 is a very close sibling of the AXP313A. The only
difference seems to be the ability to dual-phase the first two DC/DC
converter, which adds another register.

Add the required boilerplate to introduce a new PMIC to the AXP MFD
driver. Where possible, this just maps into the existing structs defined
for the AXP313A, only deviating where needed.

At the moment there is an implicit relationship between the AXP model
IDs and the order of the strings in the axp20x_model_names[] array.
This is fragile, and makes adding IDs in the middle error prone.

Make this relationship official by changing the ID type to the actual

cc52dc2fe3 pwm: Changes for v6.12-rc1 
This pull request contains some cleanups to the core and some mostly
 minor updates to a bunch of drivers and device tree bindings. One thing
 worth pointing out is that it contains an immutable branch containing
 support for a new mfd chip (Analog Devices ADP5585) with several sub
 drivers. So expect to get the four affected commits also from my fellow
 MFD and GPIO maintainers.

 Herring and Wolfram Sang for code contributions and reviews and to Lee

The ADP5585 is a 10/11 input/output port expander with a built in keypad
matrix decoder, programmable logic, reset generator, and PWM generator.
This driver supports the chip by modelling it as an MFD device, with two
child devices for the GPIO and PWM functions.

The driver is derived from an initial implementation from NXP, available
in commit 8059835bee19 ("MLK-25917-1 mfd: adp5585: add ADI adp5585 core
support") in their BSP kernel tree. It has been extensively rewritten.

769cb63166 mfd: syscon: Add of_syscon_register_regmap() API 
The of_syscon_register_regmap() API allows an externally created regmap
to be registered with syscon. This regmap can then be returned to client
drivers using the syscon_regmap_lookup_by_phandle() APIs.

The API is used by platforms where mmio access to the syscon registers is
not possible, and a underlying soc driver like exynos-pmu provides a SoC
specific regmap that can issue a SMC or hypervisor call to write the
register.

This approach keeps the SoC complexities out of syscon, but allows common
drivers such as  syscon-poweroff, syscon-reboot and friends that are used
by many SoCs already to be re-used.
