Pull RTC updates from Alexandre Belloni:
 "We see a net reduction of the number of lines of code thanks to the

Uwe Kleine-König 860e98066f mfd: lp3943: Drop #include <linux/pwm.h> from header
The header doesn't make use of any symbols declared in <linux/pwm.h>.
There are tree files that #include <mfd/lp3943.h>. Two of them
(i.e. drivers/gpio/gpio-lp3943.c and drivers/mfd/lp3943.c) also don't
use any and the third (drivers/pwm/pwm-lp3943.c) has an explicit include
of <linux/pwm.h> itself.

So drop the unused include. The intended side effect is that
drivers/gpio/gpio-lp3943.c and drivers/mfd/lp3943.c stop importing the
"PWM" module namespace.

Identification and hardware configuration registers allow to read the

So, rework the probe to avoid touching ARR register by simply read the
counter width when available. This may avoid messing with a possibly
running timer.
Also add useful bit fields to stm32-timers header file.

Thomas Richard 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>.

Heiko Stuebner 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.

Heiko Stuebner 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.

Linus Torvalds 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

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.

  Summary:

  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:
   - GPIO part of the MFD Congatec Board Controller
   - PolarFire GPIO controller
   - 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

   - kernel doc and comments tweaks

Andre Przywara 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
enum used, and using indexed initialisers for the string list.

`pm800_irq`, `pm805_irq` and `pm805_irq_chip` are not modified and can
be declared as const to move their data to a read-only section.

In order to keep the const modifier for the regmap_irq_chip structures,
the pointer used to reference them must be converted to const as well.
