There are few issues with the current code:
- the error code from kstrtouint() is shadowed
- the error code from asus_wmi_set_devstate() is ignored
- the extra check against 0 for count (this is guaranteed by sysfs)
Fix these issues by doing a slight refactoring of charge_threshold_store().

Previously, asus-wmi was using the AGFN interface and FAN_CTRL device
for CPU fan control. However, this code has been found to be not fully
working on some recent products, and having checked the spec, these
interfaces are marked as being removed from future products currently
in development.
The replacement appears to be the CPU_FAN device, added in spec version
8.3 (March 2014) and present on many modern Asus laptops.
Add support for this device, and use it whenever it is detected.
The older approach based on AGFN and FAN_CTRL is used as a fallback
on products that do not have such device.
Other than switching between automatic and full speed, there is
no fan speed control through this new interface.

The asus-wmi driver currently uses the "AGFN" interface and
the FAN_CTRL device for fan control. According to the spec, this
interface is very dated and marked as pending removal from products
currently in development.
Clean up the way that the AGFN fan is detected and handled, also
preparing the driver for the introduction of an alternate fan
control method needed to support recent Asus products.
Not anticipating further development of this interface, simplify
the code by dropping any notion of being able to control multiple
AGFN fans (this was already limited to just a single fan through only
exposing a single fan in sysfs).
Check for the presence of AGFN fans at probe time, simplifying the code
flow in asus_hwmon_sysfs_is_visible().

The APU3+ boards have two SIM sockets, while only one of them
can be routed to the mpcie slots at a time. Selection is done
via simswap gpio.
We currently don't have a fitting subsystem for those cases yet,
so just wire it up to a LED for the time being. While this isn't
really semantically correct, it's a good compromise.

On APUx we have also mpcie2/mpcie3 reset pins. To make it possible to reset
the ports from the userspace, add the definition to this platform
device. The gpio can then be exported by the legancy gpio subsystem to
toggle the mpcie reset pin.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array.
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.

kmemdup is introduced to duplicate a region of memory in a neat way.
Rather than kmalloc/kzalloc + memcpy, which the programmer needs to
write the size twice (sometimes lead to mistakes), kmemdup improves
readability, leads to smaller code and also reduce the chances of mistakes.
Suggestion to use kmemdup rather than using kmalloc/kzalloc + memcpy.

Pull x86 cpu-feature updates from Ingo Molnar:
- Rework the Intel model names symbols/macros, which were decades of
ad-hoc extensions and added random noise. It's now a coherent, easy
to follow nomenclature.
- Add new Intel CPU model IDs:
- "Tiger Lake" desktop and mobile models
- "Elkhart Lake" model ID
- and the "Lightning Mountain" variant of Airmont, plus support code
- Add the new AVX512_VP2INTERSECT instruction to cpufeatures
- Remove Intel MPX user-visible APIs and the self-tests, because the
toolchain (gcc) is not supporting it going forward. This is the
first, lowest-risk phase of MPX removal.
- Remove X86_FEATURE_MFENCE_RDTSC

After changing the valid_mask for the struct gpio_chip
to detect the need and presence of a valid mask with the
presence of a .init_valid_mask() callback to fill it in,
we augment the gpio_irq_chip to use the same logic.
Switch all driver using the gpio_irq_chio valid_mask
over to this new method.
This makes sure the valid_mask for the gpio_irq_chip gets
filled in when we add the gpio_chip, which makes it a
little easier to switch over drivers using the old
way of setting up gpio_irq_chip over to the new method
of passing the gpio_irq_chip along with the gpio_chip.
(See drivers/gpio/TODO for details.)

The Asus WMI spec indicates that the function being controlled here
is called "Fan Boost Mode". The user-facing documentation also calls it
this.
The spec uses the term "fan mode" is used to refer to other things,
including functionality expected to appear on future products.
We missed this before as we are not dealing with the most readable of
specs, and didn't forsee any confusion around shortening the name.
Rename "fan mode" to "fan boost mode" to improve consistency with the
spec and to avoid a future naming conflict.
There is no interface breakage here since this has yet to be included
in an official kernel release. I also updated the kernel version listed
under ABI accordingly.

Dell platform team told us that some (DMI whitelisted) Dell Latitude
machines have ST microelectronics accelerometer at I2C address 0x29.
Presence of that ST microelectronics accelerometer is verified by existence
of SMO88xx ACPI device which represent that accelerometer. Unfortunately
ACPI device does not specify I2C address.
This patch registers lis3lv02d device for selected Dell Latitude machines
at I2C address 0x29 after detection. And for Dell Vostro V131 machine at
I2C address 0x1d which was manually detected.
Finally commit a7ae81952cda ("i2c: i801: Allow ACPI SystemIO OpRegion to
conflict with PCI BAR") allowed to use i2c-i801 driver on Dell machines so
lis3lv02d correctly initialize accelerometer.
Tested on Dell Latitude E6440.

Pull x86 platform driver updates from Andy Shevchenko:
"Gathered a bunch of x86 platform driver changes. It's rather big,
since includes two big refactors and completely new driver:
- ASUS WMI driver got a big refactoring in order to support the TUF
Gaming laptops. Besides that, the regression with backlight being
permanently off on various EeePC laptops has been fixed.
- Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
X axis being inverted. This has been fixed.
- Intel PMC core driver has been extended to be ACPI enumerated if
the DSDT provides device with _HID "INT33A1". This allows to
convert the driver to be pure platform and support new hardware
purely based on ACPI DSDT.
- From now on the Intel Speed Select Technology is supported thru a
corresponding driver. This driver provides an access to the
features of the ISST, such as Performance Profile, Core Power, Base
frequency and Turbo Frequency.
- Mellanox platform drivers has been refactored and now extended to
support more systems, including new coming ones.
- The OLPC XO-1.75 platform is now supported.
- CB4063 Beckhoff Automation board is using PMC clocks, provided via
pmc_atom driver, for ethernet controllers in a way that they can't
be managed by the clock driver. The quirk has been extended to
cover this case.
- Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
the information of Chuwi Hi10 Air has been fixed to cover more
models based on the same platform.
- Xiaomi notebooks have WMI interface enabled. Thus, the driver to
support it has been provided. It required some extension of the
generic WMI library, which allows to propagate opaque context to
the ->probe() of the individual drivers.
This release includes debugfs clean up from Greg KH for several
drivers that drop return code check and make debugfs absence or
failure non-fatal.
Also miscellaneous fixes here and there, mostly for Acer WMI and
various Intel drivers"

Most modern platforms already have the ACPI device "INT33A1" that could
be used to attach to the driver. Switch the driver to using that and
thus make the intel_pmc_core.c a pure platform_driver.
Some of the legacy platforms though, may still not have this ACPI device
in their ACPI tables. Thus for such platforms, move the code to manually
instantiate a platform_device into a new file of its own. This would
instantiate the intel_pmc_core platform device and thus attach to
the driver, if the ACPI device for the same ("INT33A1") is not present
in a system where it should be. This was discussed here:

into microseconds
Refer to the Intel SDM Vol.4, the package C-state residency counters
of modern IA micro-architecture are all ticking in TSC frequency,
hence we can apply simple math to transform the ticks into microseconds.
i.e.,
residency (ms) = count / tsc_khz
residency (us) = count / tsc_khz * 1000
This also aligns to other sysfs debug entries of residency counter in
the same metric in microseconds, benefits reading and scripting.

Modify DMI matching order: perform matching based on DMI_BOARD_NAME
before matching based on DMI_BOARD_VENDOR and DMI_PRODUCT_NAME in order
to reduce the number of ‘dmi_table’ entries necessary for new systems
support and keep matching order in logical way.
For example, the existing check for DMI_PRODUCT_NAME with prefixes
“MSN27", “MSN24”, "MSB” matches systems MSN2700-BXXXX, MSN2700-XXXX,
MSN2410-BXXXX, MSB7800-XXXX, where ‘XXXX’ specifies some systems
hardware flavors.
At the same time these systems also matched by DMI_BOARD_NAME
“VMOD0001”, because they all have the same platform configuration (LED,
interrupt control, mux etcetera).
New systems with different platform configuration, but with similar
DMI_PRODUCT_NAME MSN2700-2XXXX, MSN2700-2XXXX, MSB7800-2XXXX are about
to be added. These system have similar DMI_PRODUCT_NAME, since they
have same ports configuration as their predecessors. All new systems
will be matched by DMI_BOARD_NAME “VMOD0008”.
With the change provided in the patch it is enough just to add
“VMOD0008” match following natural after “VMOD0007”, otherwise
“VMOD0008” or all “MSN2700-2XXXX”, “MSN2700-2XXXX”, “MSB7800-2XXXX”
should be added on top of ‘mlxplat_dmi_table” in order to be matched
before “MSN27", “MSN24”, "MSB”.

Activate 'i2c-mlxcpld' driver with 'platform_device_register_resndata'
instead off 'platform_device_register_simple' in order to pass platform
specific info.
Add platform i2c data for the next generation systems.

Commands which causes PUNIT writes, store them and restore them on system
resume. The driver stores all such requests in a hash table and stores the
the latest mailbox request parameters. On resume these commands mail box
commands are executed again. There are only 5 such mail box commands which
will trigger such processing so a very low overhead in store and execute
on resume. Also there is no order requirement for mail box commands for
these write/set commands. There is one MSR request for changing turbo
ratio limits, this also stored and get restored on resume and cpu online.

While using new non arhitectural features using PUNIT Mailbox and MMIO
read/write interface, still there is need to operate using MSRs to
control PUNIT. User space could have used user user-space MSR interface for
this, but when user space MSR access is disabled, then it can't. Here only
limited number of MSRs are allowed using this new interface.
