Commit 10a08fd65ec1 ("ACPI: PM: Set up EC GPE for system wakeup from
drivers that need it") assumed that the EC GPE would only need to be
set up for system wakeup if either the intel-hid or the intel-vbtn
driver was in use, but that turns out to be incorrect. In particular,
on ASUS Zenbook UX430UNR/i7-8550U, if the EC GPE is not enabled while
suspended, the system cannot be woken up by opening the lid or
pressing a key, and that machine doesn't use any of the drivers
mentioned above.
For this reason, always set up the EC GPE for system wakeup from
suspend-to-idle by setting and clearing its wake mask in the ACPI
suspend-to-idle callbacks.

The use of sscanf() is an overkill here. Moreover, there is no need to check
for count to be 0, since it's guaranteed by sysfs not to be.

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().

Merge tag 'v5.3-rc4' into next
Sync up with mainline to bring in device_property_count_u32 andother
newer APIs.
Notice that intel_button_array_enable() never disables the power
button which is the only one needed to wake up the system from
suspend-to-idle, so it can be safely called during suspend-to-idle
as well as during "regular" system suspend, and rearrange the
code in the driver's "suspend" and "resume" callbacks accordingly.
While at it, use pm_suspend_no_platform() to check if the current
suspend-resume cycle is suspend-to-idle, as that is the only
case when the device should be enabled while suspended.

Both intel-hid and intel-vbtn set a wakeup_mode flag causing them
to behave in a special way during system suspend and while suspended
in their "prepare" PM callbacks and clear it in their "resume" PM
callbacks. That may cause the wakeup_mode flag to remain set after
a system suspend failure (if some other driver's "suspend" callback
returns an error before the "suspend" callback of either intel-hid
or intel-vbtn is invoked).
After commit 10a08fd65ec1 ("ACPI: PM: Set up EC GPE for system wakeup
from drivers that need it") that also affects the "wakeup mask" bit
of the EC GPE, which may not be cleared after a failing system
suspend.
Fix this issue by adding "complete" PM callbacks to intel-hid and
intel-vbtn to clear the wakeup_mode flag and the "wakeup mask" bit
of the EC GPE if they have not been cleared earlier.

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 EC GPE needs to be set up for system wakeup only if there is a
driver depending on it, either intel-hid or intel-vbtn, bound to a
button device that is expected to wake up the system from sleep (such
as the power button on some Dell systems, like the XPS13 9360). It
doesn't need to be set up for waking up the system from sleep in any
other cases and whether or not it is expected to wake up the system
from sleep doesn't depend on whether or not the LPS0 device is
present in the ACPI namespace.
For this reason, rearrange the ACPI suspend-to-idle code to make the
drivers depending on the EC GPE wakeup take care of setting it up and
decouple that from the LPS0 device handling.
While at it, make intel-hid and intel-vbtn prepare for system wakeup
only if they are allowed to wake up the system from sleep by user
space (via sysfs).
[Note that acpi_ec_mark_gpe_for_wake() and acpi_ec_set_gpe_wake_mask()
are there to prevent the EC GPE from being disabled by the
acpi_enable_all_wakeup_gpes() call in acpi_s2idle_prepare(), so on
systems with either intel-hid or intel-vbtn this change doesn't
affect any interactions with the hardware or platform firmware.]

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.

Pull i2c updates from Wolfram Sang:
"New stuff from the I2C world:
- in the core, getting irqs from ACPI is now similar to OF
- new driver for MediaTek MT7621/7628/7688 SoCs
- bcm2835, i801, and tegra drivers got some more attention
- GPIO API cleanups
- cleanups in the core headers
- lots of usual driver updates"

Rename the laptops documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

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.
Miscellaneous fixes here and there, mostly for Acer WMI and
various Intel drivers.
The listed below commits are duplicated due to previously pushed fixes in v5.2 cycle:
- 1dd93f873d8e platform/x86: asus-wmi: Only Tell EC the OS will handle display hotkeys from asus_nb_wmi
- 89ae3a073625 platform/x86: intel-vbtn: Report switch events when event wakes device
- fa882fc80dc8 platform/x86: mlx-platform: Fix parent device in i2c-mux-reg device registration
