This driver uses the legacy gpiolib interfaces to get gpio
numbers from platform data. There are no in-tree users of
this driver, so nothing defines the platform data.
Add a dependency on GPIOLIB_LEGACY for the moment to avoid the build
failure, and make sure the sound driver does not get built without the
mfd portion either pass that dependency along.
Alternatively, we could remove the mfd driver along with the backlight
and regulator portions.

clang-21 warns about one uninitialized variable getting dereferenced
in madera_dev_init:
drivers/mfd/madera-core.c:739:10: error: variable 'mfd_devs' is uninitialized when used here [-Werror,-Wuninitialized]
739 | mfd_devs, n_devs,
| ^~~~~~~~
drivers/mfd/madera-core.c:459:33: note: initialize the variable 'mfd_devs' to silence this warning
459 | const struct mfd_cell *mfd_devs;
| ^
| = NULL
The code is actually correct here because n_devs is only nonzero
when mfd_devs is a valid pointer, but this is impossible for the
compiler to see reliably.
Change the logic to check for the pointer as well, to make this easier
for the compiler to follow.

When `devm_add_action_or_reset()` fails, it is due to a failed memory
allocation and will thus return `-ENOMEM`. `dev_err_probe()` doesn't do
anything when error is `-ENOMEM`. Therefore, remove the useless call to
`dev_err_probe()` when `devm_add_action_or_reset()` fails, and just
return the value instead.

We observed the initial probe of the da9063 failing in
da9063_get_device_type in about 30% of boots on a Xilinx ZynqMP based
board. The problem originates in da9063_i2c_blockreg_read, which uses
a single bus transaction to turn the register page and then read a
register. On the bus, this should translate to a write to register 0,
followed by a read to the target register, separated by a repeated
start. However, we found that after the write to register 0, the
controller sometimes continues directly with the register address of
the read request, without sending the chip address or a repeated start
in between, which makes the read request invalid.
To fix this, separate turning the page and reading the register into
two separate transactions. This brings the initialization code in line
with the rest of the driver, which uses register maps (which to my
knowledge do not use repeated starts after turning the page). This has
been included in our kernel for several months and was recently
included in a shipped product. For us, it reliably fixes the issue,
and we have not observed any new issues.
While the underlying problem is probably with the i2c controller or
its driver, I still propose a change here in the interest of
robustness: First, I'm not sure this issue can be fixed on the
controller side, since there are other issues related to repeated
start which can't (AR# 60695, AR# 61664). Second, similar problems
might exist with other controllers.

Testing has shown that reading multiple registers at once (for 10-bit
ADC values) does not work. Set the use_single_read regmap_config flag
to make regmap split these for us.
This should fix temperature opregion accesses done by
drivers/acpi/pmic/intel_pmic_chtdc_ti.c and is also necessary for
the upcoming drivers for the ADC and battery MFD cells.

Commit 9e36775c22c7 ("mfd: kempld: Remove custom DMI matching code")
removes the ability to load the driver if no matching system DMI data
is found. Before this commit the driver could be loaded using
alternative methods such as ACPI or `force_device_id` in the absence
of a matching system DMI entry.
Restore this ability while keeping the refactored

parts and put it with the other Maxim parts. No functional changes
just alphabetising.

Pull regulator updates from Mark Brown:
"The big change in this release is the addition of Rust bindings from
Daniel Almeida, allowing fairly basic consumer use with support for
enable and voltage setting operations. This should be good for the
vast majority of consumers.
Otherwise it's been quite quiet, a few new devices supported, plus
some cleanups and fixes.
Summary:
- Basic Rust bindings
- A fix for making large voltage changes on regulators where we limit
the size of voltage change we will do in one step, previously we
just got as close as we could in one step
- Cleanups of our usage of the PM autosuspend functions, this pulls
in some PM core changes on a shared tag
- Mode setting support for PCA9450
- Support for Mediatek MT6893 and MT8196 DVFSRC, Qualcomm PM7550 and
PMR735B, Raspberry Pi displays and TI TPS652G1
The TI driver pulls in the MFD portion of the support for the device
and the pinctrl driver which was in the same tag"

Pull gpio updates from Bartosz Golaszewski:
"There's one new driver (Apple SMC) and extensions to existing drivers
for supporting new HW models. A lot of different impovements across
drivers and in core GPIO code. Details on that are in the signed tag
as usual.
We managed to remove some of the legacy APIs. Arnd Bergmann started to
work on making the legacy bits optional so that we may compile them
only for older platforms that still really need them.
Rob Herring has done a lot of work to convert legacy .txt dt-bindings
for GPIO controllers to YAML. There are only a few left now in the
GPIO tree.
A big part of the commits in this PR concern the conversion of GPIO
drivers to using the new line value setter callbacks. This conversion
is now complete treewide (unless I've missed something) and once all
the changes from different trees land in mainline, I'll send you
another PR containing a commit dropping the legacy callbacks from the
tree.
As the quest to pay back technical dept never really ends, we're
starting another set of interface conversions, this time it's about
moving fields specific to only a handful of drivers using the
gpio-mmio helper out of the core gpio_chip structure that every
controller implements and uses. This cycle we introduce a new set of
APIs and convert a few drivers under drivers/gpio/, next cycle we'll
convert remaining modules treewide (in gpio, pinctrl and mfd trees)
and finally remove the old interfaces and move the gpio-mmio fields
into their own structure wrapping gpio_chip.
One last change I should mention here is the rework of the sysfs
interface. In 2016, we introduced the GPIO character device as the
preferred alternative to the sysfs class under /sys/class/gpio. While
it has seen a wide adoption with the help of its user-space
counterpart - libgpiod - there are still users who prefer the
simplicity of sysfs.
As far as the GPIO subsystem is concerned, the problem is not the
existince of the GPIO class as such but rather the fact that it
exposes the global GPIO numbers to the user-space, stopping us from
ever being able to remove the numberspace from the kernel. To that
end, this release we introduced a parallel, limited sysfs interface
that doesn't expose these numbers and only implements a subset of
features that are relevant to the existing users. This is a result of
several discussions over the course of last year and should allow us
to remove the legacy part some time in the future.
Summary:
GPIOLIB core:
- introduce a parallel, limited sysfs user ABI that doesn't expose
the global GPIO numbers to user-space while maintaining backward
compatibility with the end goal of it completely replacing the
existing interface, allowing us to remove it
- remove the legacy devm_gpio_request() routine which has no more
users
- start the process of allowing to compile-out the legacy parts of
the GPIO core for users who don't need it by introducing a new
Kconfig option: GPIOLIB_LEGACY
- don't use global GPIO numbers in debugfs output from the core code
(drivers still do it, the work is ongoing)
- start the process of moving the fields specific to the gpio-mmio
helper out of the core struct gpio_chip into their own structure
that wraps it: create a new header with modern interfaces and
convert several drivers to using it
- remove the platform data structure associated with the gpio-mmio
helper from the kernel after having converted all remaining users
to generic device properties
- remove legacy struct gpio definition as it has no more users
New drivers:
- add the GPIO driver for the Apple System Management Controller
Driver improvements:
- add support for new models to gpio-adp5585, gpio-tps65219 and
gpio-pca953x
- extend the interrupt support in gpio-loongson-64bit
- allow to mark the simulated GPIO lines as invalid in gpio-sim
- convert all remaining GPIO drivers to using the new GPIO value
setter callbacks
- convert gpio-rcar to using simple device power management ops
callbacks
- don't check if current direction of a line is output before setting
the value in gpio-pisosr and ti-fpc202: the GPIO core already
handles that
- also drop unneeded GPIO range checks in drivers, the core already
makes sure we're within bounds when calling driver callbacks
- use dev_fwnode() where applicable across GPIO drivers
- set line value in gpio-zynqmp-modepin and gpio-twl6040 when the
user wants to change direction of the pin to output even though
these drivers don't need to do anything else to actually set the
direction, otherwise a call like gpiod_direction_output(d, 1) will
not result in the line driver high
- remove the reduntant call to pm_runtime_mark_last_busy() from
gpio-arizona
- use lock guards in gpio-cadence and gpio-mxc
- check the return values of regmap functions in gpio-wcd934x and
gpio-tps65912
- use better regmap interfaces in gpio-wcove and gpio-pca953x
- remove dummy GPIO chip callbacks from several drivers in cases
where the GPIO core can already handle their absence
- allow building gpio-palmas as a module
Fixes:
- use correct bit widths (according to the documentation) in
gpio-virtio
Device-tree bindings:
- convert several of the legacy .txt documents for many different
devices to YAML, improving automatic validation
- create a "trivial" GPIO DT schema that covers a wide range of
simple hardware that share a set of basic GPIO properties
- document new HW: Apple MAC SMC GPIO block and adp5589 I/O expander
- document a new model for pca95xx
- add and/or remove properties in YAML documents for gpio-rockchip,
fsl,qoriq-gpio, arm,pl061 and gpio-xilinx
Misc:
- some minor refactoring in several places, adding/removing forward
declarations, moving defines to better places, constify the
arguments in some functions, remove duplicate includes, etc.
- documentation updates"

Originally an explicit ID for the AXP313/AXP323 regulator was set to
avoid a conflict with the primary AXP717 PMIC on Allwinner A523 family
boards.
This didn't entirely work since on some or all of these boards, the
interrupt line on this secondary PMIC was left unconnected, and thus
the driver would fall back to the generic "no interrupt; only regulators"
case, which didn't have the explicit ID set, thus undoing the intended
fix.
Also set an explicit ID for the regulator cell in the no IRQ generic
fall back case. This fixes the conflict for the AXP717 + AXP313/AXP323
case. For the actual single PMIC with no IRQ connected case, the ID does
not affect functionality, only the device naming of the regulator cell,
and by extension the name and path under sysfs.
