Support for the Motorola EZX phones based on Intel PXA processors was
removed in 2022, but this driver remained present in the tree. As far
as I can tell, the support was never quite functional upstream because
the board files did not actually instantiate the SPI device for the PCAP.
There are still also drivers for the various mfd cells: keys, touchscreen,
regulator and rtc, all of which are obviously orphaned as well but can
be removed separately as the Kconfig dependency now prevents them from
being enabled.

Improve code style. This includes the following:
- Formatting the max77759_chgr_irqs entries to fit in a single line
instead of breaking them into multiple lines to improve readability.
- Refactoring comments such that they're full sentences and have
punctuation marks for a couple of macro definitions to adhere to the
documentation style.
- Explicitly initializing `MAX77759_CHGR_MODE_OFF`.

The old-style gpio handling in wm8994 came from a commit 7c8844481a1c
("mfd: wm8994: Emulate level triggered interrupts if required") in
linux-3.11, but nothing in the kernel ever set the 'irq_gpio' member
in the wm8994_pdata structure, so this was always dead code.
Remove it now to reduce the dependency on the legacy gpio interfaces.

There are board files in-tree that want to request GPIOs from this chip.
They currently rely on the GPIO core's mechanism of matching software
nodes' labels against GPIO controller names. We want to remove this
behavior from the kernel and to this end, we need to associate the
referenced GPIO controller with its target software node.
Create a dedicated GPIO software node for cs5535, assign it to the GPIO
cell and expose its address in a new header.
We only expose a single software node instance but that's alright: all
existing hardware only contains a single cs5535 companion and the geode
board file for which we expose this is legacy anyway.

Add register definitions and a new 'type' enum to be passed via MFD
private data to support the BQ25792, which is a newer variant of the

BQ25792 shares similar logic of operation with the already supported
BQ25703A but has a completely different register map and different
electrical constraints.

The BD72720 header reserves an ID for BUCK11. While this does not (at
the moment) cause problems I can see, it is misleading as the BD72720

Samsung's S2MU005 PMIC includes subdevices for a charger, an MUIC (Micro
USB Interface Controller), and flash and RGB LED controllers.
S2MU005's interrupt registers divided into three domains, each for the
charger, flash LEDs, and the MUIC, packed into a single regmap IRQ chip
construct.
In devices other than S2MPG1X, the revision can be retrieved from the
first register of the PMIC regmap. In S2MU005 however, the location is
in offset 0x73. Introduce a switch-case block to allow selecting the
REG_ID register. S2MU005 also has a field mask for the revision. Apply
it using FIELD_GET() and get the extracted value.
Add initial support for S2MU005 in the PMIC driver, along with its three
interrupt chips, and support for allowing to fetch revision based on the
device variant.

CIDs set for MT6328, MT6331 and MT6332 are not appropriate.
Many Android downstream kernels define CID as below,
MT6328:
#define PMIC6328_E1_CID_CODE 0x2810
#define PMIC6328_E2_CID_CODE 0x2820
#define PMIC6328_E3_CID_CODE 0x2830
MT6331/MT6332:
#define PMIC6331_E1_CID_CODE 0x3110
#define PMIC6331_E2_CID_CODE 0x3120
#define PMIC6331_E3_CID_CODE 0x3130
#define PMIC6332_E1_CID_CODE 0x3210
#define PMIC6332_E2_CID_CODE 0x3220
#define PMIC6332_E3_CID_CODE 0x3230
The current configuration incorrectly uses the revision code as the CID.
Therefore, the driver cannot detect the same PMIC of different revisions.
(E1/E2 for MT6328, E1/E3 for MT6331/MT6332)
Based on these, the CID of MT6328, MT6331 and MT6332 should be corrected.
Additionally, the incorrect MT6331/MT6332 CID overlaps with the MT6320's
actual CID:
#define PMIC6320_E1_CID_CODE 0x1020
#define PMIC6320_E2_CID_CODE 0x2020
This causes a conflict in the switch-case statement of mt6397-irq.c,
this prevents adding support for MT6320.

One of the users of this driver - meraki-mx100 - abuses the software
node API by setting up a dummy software node without any logical link to
this GPIO controller and uses the fact that the GPIO core matches the
controller's label against the swnode's name to make the lookup work.
We want to remove this behavior from GPIOLIB in favor of actual matching
of firmware nodes but that would break this user. To facilitate that:
create a software node for the GPIO controller cell and expose its
address in the provided MFD header.

This converts the Arizona driver to use GPIO descriptors
exclusively, deletes the legacy code path an updates the
in-tree user of legacy GPIO.
The GPIO lines for mic detect polarity and headphone ID
detection are made exclusively descriptor-oriented. The
headphone ID detection could actually only be used by
the legacy GPIO code, but I converted it to use a
descriptor if someone would actually need it so we don't
just drop useful code.
The compatible "wlf,hpdet-id-gpio" is not in the device
tree bindings and only intended to be used by software
nodes if any. If someone insists I can try to add a
binding for it, but I doubt there is any real user so
it seems pointless.

Add a GPIO IRQ chip implementation for the kempld GPIO controller. Of
note is only how the parent IRQ is obtained.
The IRQ for the GPIO controller can be configured in the BIOS, along
with the IRQ for the I2C controller. These IRQ are returned by ACPI
but this information is only usable if both IRQ are configured. When
only one is configured, only one is returned making it impossible to
know which one it is.
Luckily the BIOS will set the configured IRQ in the PLD registers, so
it can be read from there instead, and that also work on platforms
without ACPI.
The vendor driver allowed to override the IRQ using a module
parameters, so there are boards in field which used this parameter
instead of properly configuring the BIOS. This implementation provides
this as well for compatibility.

The S2MPG10 PMIC is a Power Management IC for mobile applications with
buck converters, various LDOs, power meters, RTC, clock outputs, and
additional GPIO interfaces.
It has 10 buck and 31 LDO rails. Several of these can either be
controlled via software (register writes) or via external signals, in
particular by:
* one out of several input pins connected to a main processor's:
* GPIO pins
* other pins that are e.g. firmware- or power-domain-controlled
without explicit driver intervention
* a combination of input pins and register writes.
Control via input pins allows PMIC rails to be controlled by firmware,
e.g. during standby/suspend, or as part of power domain handling where
otherwise that would not be possible. Additionally toggling a pin is
faster than register writes, and it also allows the PMIC to ensure that
any necessary timing requirements between rails are respected
automatically if multiple rails are to be enabled or disabled quasi
simultaneously.
This commit implements support for all these rails and control
combinations.
Additional data needs to be stored for each regulator, e.g. the input
pin for external control, or a rail-specific ramp-rate for when
enabling a buck-rail. Therefore, probe() is updated slightly to make
that possible.
Note1: For an externally controlled rail, the regulator_ops provide an
empty ::enable() and no ::disable() implementations, even though Linux
can not enable the rail and one might think ::enable could be NULL.
Without ops->enable(), the regulator core will assume enabling such a
rail failed, though, and in turn never add a reference to its parent
(supplier) rail. Once a different (Linux-controlled) sibling (consumer)
rail on that same parent rail gets disabled, the parent gets disabled
(cutting power to the externally controlled rail although it should
stay on), and the system will misbehave.
Note2: While external control via input pins appears to exist on other
versions of this PMIC, there is more flexibility in this version, in
particular there is a selection of input pins to choose from for each
rail (which must therefore be configured accordingly if in use),
whereas other versions don't have this flexibility.

Add support for Samsung's S2MPG11 PMIC, which is a Power Management IC
for mobile applications with buck converters, various LDOs, power
meters, NTC thermistor inputs, and additional GPIO interfaces. It
typically complements an S2MPG10 PMIC in a main/sub configuration as
the sub-PMIC.
Like S2MPG10, communication is not via I2C, but via the Samsung ACPM
firmware.
While at it, we can also switch to asynchronous probe, which helps with
probe performance, as the drivers for s2mpg10 and s2mpg11 can probe in
parallel.
Note: The firmware uses the ACPM channel ID and the Speedy channel ID
to select the PMIC address. Since these are firmware properties, they
can not be retrieved from DT, but instead are deducted from the
compatible for now.

Bucks can reasonably be supplies for LDOs, but not the other way
around. Since rail registration is going to be ordered by 'enum
s2mpg10_regulators', it makes sense to specify bucks first, so that
during LDO registration it is more likely that the corresponding supply
is known already.
This can improve probe speed, as no unnecessary deferrals and retries
are required anymore.

Using a threaded interrupt without a dedicated primary handler mandates
the IRQF_ONESHOT flag to mask the interrupt source while the threaded
handler is active. Otherwise the interrupt can fire again before the
threaded handler had a chance to run.
Mark explained that this should not happen with this hardware since it
is a slow irqchip which is behind an I2C/ SPI bus but the IRQ-core will
refuse to accept such a handler.
Set IRQF_ONESHOT so the interrupt source is masked until the secondary
handler is done.

The TPS65214 PMIC variant has a LOCK_REG register that prevents writes to
nearly all registers when locked. Unlock the registers at probe time and
leave them unlocked permanently.
This approach is justified because:
- Register locking is very uncommon in typical system operation
- No code path is expected to lock the registers during runtime
- Adding a custom regmap write function would add overhead to every
register write, including voltage changes triggered by CPU OPP
transitions from the cpufreq governor which could happen quite
frequently

The ROHM BD72720 is a power management IC which continues the BD71828
family of PMICs. Similarly to the BD71815 and BD71828, the BD72720
integrates regulators, charger, RTC, clock gate and GPIOs.
The main difference to the earlier PMICs is that the BD72720 has two
different I2C slave addresses. In addition to the registers behind the
'main I2C address', most of the charger (and to some extent LED) control
is done via registers behind a 'secondary I2C slave address', 0x4c.

On S2MPG10 (and similar like S2MPG11), top-level interrupt status and
mask registers exist which need to be unmasked to get the PMIC
interrupts. This additional status doesn't seem to exist on other PMICs
in the S2MP* family, and the S2MPG10 driver is manually dealing with
masking and unmasking currently.
The correct approach here is to register this hierarchy as chained
interrupts, though, without any additional manual steps. Doing so will
also simplify addition of other, similar, PMICs (like S2MPG11) in the
future.
Update the driver to do just that.

Pull Char/Misc/IIO/Binder updates from Greg KH:
"Here is the big set of char/misc/iio and other driver subsystem
changes for 6.18-rc1.
Loads of different stuff in here, it was a busy development cycle in
lots of different subsystems, with over 27k new lines added to the
tree.
Included in here are:
- IIO updates including new drivers, reworking of existing apis, and
other goodness in the sensor subsystems
- MEI driver updates and additions
- NVMEM driver updates
- slimbus removal for an unused driver and some other minor updates
- coresight driver updates and additions
- MHI driver updates
- comedi driver updates and fixes
- extcon driver updates
- interconnect driver additions
- eeprom driver updates and fixes
- minor UIO driver updates
- tiny W1 driver updates
But the majority of new code is in the rust bindings and additions,
which includes:
- misc driver rust binding updates for read/write support, we can now
write "normal" misc drivers in rust fully, and the sample driver
shows how this can be done.
- Initial framework for USB driver rust bindings, which are disabled
for now in the build, due to limited support, but coming in through
this tree due to dependencies on other rust binding changes that
were in here. I'll be enabling these back on in the build in the
usb.git tree after -rc1 is out so that developers can continue to
work on these in linux-next over the next development cycle.
- Android Binder driver implemented in Rust.
This is the big one, and was driving a huge majority of the rust
binding work over the past years. Right now there are two binder
drivers in the kernel, selected only at build time as to which one
to use as binder wants to be included in the system at boot time.
The binder C maintainers all agreed on this, as eventually, they
want the C code to be removed from the tree, but it will take a few
releases to get there while both are maintained to ensure that the
rust implementation is fully stable and compliant with the existing
userspace apis.
All of these have been in linux-next for a while"

The only machine that still uses the old gpio number based interface
is the wlf_cragg_6410 board file. In order to remove the dependency
on the interfaces, add #ifdef blocks here.

Relying on other components to include those basic types is unreliable
and may cause compile errors like:
../include/linux/mfd/qnap-mcu.h:13:9: error: unknown type name ‘u32’
13 | u32 baud_rate;
| ^~~
../include/linux/mfd/qnap-mcu.h:17:9: error: unknown type name ‘bool’
17 | bool usb_led;
| ^~~~
So make sure, the types used in the header are available.
