ca42c119fc platform/x86: acer-wmi: Add Turbo Mode support for Acer PH315-53
The Acer Predator Helios series (usually denoted by PHxxx-yy) features
a particular key above the keyboard named "TURBO".
The turbo key does 3 things:
1. Set all fan's speeds to TURBO mode
2. Overclocks the CPU and GPU in the safe range
3. Turn on an LED just below the turbo button

All the above actions are operating using WMI function calls,
and there is no custom OC level for turbo. It acts as a flag
for enabling turbo mode instead of telling processors to use
a specific multiply of power (e.g. 1.3x of power).

I've run some benchmark tests and it worked fine:

GpuTest 0.7.0
http://www.geeks3d.com

Module: FurMark
Normal mode Score: 7289 points (FPS: 121)
Turbo mode Score: 7675 points (FPS: 127)
Settings:
- 1920x1080 fullscreen
- antialiasing: Off
- duration: 60000 ms

Renderer:
- GeForce RTX 2060/PCIe/SSE2
- OpenGL: 4.6.0 NVIDIA 460.32.03

This feature is presented by Acer officially and should not harm
hardware in any case.

A challenging part of implementing this feature is that calling
overclock function requires knowing the exact count of fans
for CPU and GPU of each model, which to the best of my
knowledge is not available in the kernel.

So after checking the official PredatorSense application methods, it
turned out they have provided the software the list of fans in each model.
I have access to the mentioned list, and all similar PH-iii-jj can be
added easily by matching "DMI_PRODUCT_NAME".

Creating a specific file for the Acer gaming features is not possible
because the current in use WMI event GUID is required for the turbo button
and it's not possible to register multiple listeners on a single WMI event.

ef14f0e82c platform/x86: acer-wmi: Don't use ACPI_EXCEPTION()
ACPI_EXCEPTION is only intended for internal use by the ACPICA code.

ACPI_EXCEPTION was being used here to change the apci_status code into
something human-readable, use acpi_format_exception() for this instead,
which is the proper way to do this outside of ACPICA.

5c54cb6c62 platform/x86: acer-wmi: Add support for SW_TABLET_MODE on Switch devices
Add support for SW_TABLET_MODE on the Acer Switch 10 (SW5-012) and the
acer Switch 10 (S1003) models.

There is no way to detect if this is supported, so this uses DMI based
quirks setting force_caps to ACER_CAP_KBD_DOCK (these devices have no
other acer-wmi based functionality).

The new SW_TABLET_MODE functionality can be tested on devices which
are not in the DMI table by passing acer_wmi.force_caps=0x40 on the
kernel commandline.

39aa009bb6 platform/x86: acer-wmi: Add new force_caps module parameter
Add a new force_caps module parameter to allow overriding the drivers
builtin capability detection mechanism.

This can be used to for example:
-Disable rfkill functionality on devices where there is an AA OEM DMI
 record advertising non functional rfkill switches
-Force loading of the driver on devices with a missing AA OEM DMI record

Note that force_caps is -1 when unset, this allows forcing the
capability field to 0, which results in acer-wmi only providing WMI
hotkey handling while disabling all other (led, rfkill, backlight)
functionality.

Cleanup accelerometer device handling:
-Drop acer_wmi_accel_destroy instead directly call input_unregister_device.
-The information tracked by the CAP_ACCEL flag mirrors acer_wmi_accel_dev
 being NULL. Drop the CAP flag, this is a preparation change for allowing
 users to override the capability flags. Dropping the flag stops users
 from causing a NULL pointer dereference by forcing the capability.

set_quirks has a "if (!interface) return;" check at its beginning and
interface always is NULL when set_quirks is called from find_quirks,
so it is a no-op and we can drop it.

This also allows dropping the "if (!interface) return;" from set_quirks
since set_quirks now always is called with interface != NULL.

5516745311 platform-drivers-x86 for v5.3-1
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.

0b9dd93492 platform/x86: acer-wmi: no need to check return value of debugfs_create functions
When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Also, because there is no need to save the file dentry, remove the
variable that was saving it and just recursively delete the whole
directory.

3e2bc5c5b3 platform/x86: acer-wmi: Detect RF Button capability
If a machine reports a RF Button in the communication button device
bitmap, we need to remove it before calling Get Device Status otherwise
it will return the "Undefined device" (0xE2) error code.

Although this may be a BIOS bug, we don't really need to get or set the
RF Button status. The status indicator LED embedded in the button is
controlled by firmware logic, depending on the status of the wireless
radios present on the machine (WiFi || WWAN).

This commit fixes the wireless status indicator LED on the Acer
TravelMate P648-G2-MG, and cleans the following message from the kernel
log: "Get Current Device Status failed: 0xe2 - 0x0".

f9ac89f5ad platform/x86: acer-wmi: setup accelerometer when ACPI device was found
The 98d610c373 patch was introduced since v4.11-rc1 that it causes
that the accelerometer input device will not be created on workable
machines because the HID string comparing logic is wrong.

And, the patch doesn't prevent that the accelerometer input device
be created on the machines that have no BST0001. That's because
the acpi_get_devices() returns success even it didn't find any
match device.

This patch fixed the HID string comparing logic of BST0001 device.
And, it also makes sure that the acpi_get_devices() returns
acpi_handle for BST0001.

5241b1938a platform/x86: acer-wmi: Only supports AMW0_GUID1 on acer family
The AMW0_GUID1 wmi is not only found on Acer family but also other
machines like Lenovo, Fujitsu and Medion. In the past, acer-wmi handled
those non-Acer machines by quirks list.

But actually acer-wmi driver was loaded on any machine that had
AMW0_GUID1. This behavior is strange because those machines should be
supported by appropriate wmi drivers. e.g. fujitsu-laptop,
ideapad-laptop.

This patch adds the logic to check the machine that has AMW0_GUID1
should be in Acer/Packard Bell/Gateway white list. But, it still keeps
the quirk list of those supported non-acer machines for backward
compatibility.

c460228086 acer-wmi: remove threeg and interface sysfs interfaces
Since v3.0 kernel, acer-wmi driver auto detects internal 3G device and
provides the threeg rfkill interface. So the sysfs interface of 3G is
no longer necessary now.

The 7b8aca65 patch added kernel information log to remind to user space
for the threeg sysfs interface will be removed in 2012, then b58b9ffc patch
updated the interface removing time to 2014.

I think the 3 years lead time is enough for user space application to use
rfkill instead of sysfs interface to control 3G device.

This patch removes code about threeg sysfs interface. And it also removes the
unused interface sysfs that exposes which ACPI-WMI method used by acer-wmi
driver on the machine. The information is already exposed by the acer-wmi
initial log.

183fd8fcd7 acer-wmi: Add acpi_backlight=video quirk for the Acer KAV80
The acpi-video backlight interface on the Acer KAV80 is broken, and worse
it causes the entire machine to slow down significantly after a suspend/resume.

Blacklist it, and use the acer-wmi backlight interface instead. Note that
the KAV80 is somewhat unique in that it is the only Acer model where we
fall back to acer-wmi after blacklisting, rather then using the native
(e.g. intel) backlight driver. This is done because there is no native
backlight interface on this model.

d13374154e acer-wmi: Switch to acpi_video_unregister_backlight
Switch from acpi_video_unregister(), to acpi_video_unregister_backlight(),
so that the hotkeys handler registered by acpi-video stays in place.

Since there are no mappings for the atkbd raw codes for the brightness
keys used by newer Acer models in /lib/udev/hwdb.d/60-keyboard.hwdb, and
since we map the wmi events with a code of KE_IGNORE, we rely on acpi-video
to do the hotkey handling for us.

For laptops such as the Acer Aspire 5750 which uses intel gfx this works
despite us calling acpi_video_unregister() because the following happens:

 1) acpi-video module gets loaded (as it is a dependency of acer-wmi and i915)
 2) acpi-video does NOT call acpi_video_register()
 3) acer-wmi loads (assume it loads before i915), calls
    acpi_video_dmi_promote_vendor(); which sets
    ACPI_VIDEO_BACKLIGHT_DMI_VENDOR
 4) calls acpi_video_unregister -> not registered, nop
 5) i915 loads, calls acpi_video_register
 6) acpi_video_register registers the acpi_notifier for the hotkeys,
    does NOT register a backlight device because of
    ACPI_VIDEO_BACKLIGHT_DMI_VENDOR

But on the Acer Aspire 5750G, which uses nvidia graphics the following happens:
 1) acpi-video module gets loaded (as it is a dependency of acer-wmi)
 2) acpi-video calls acpi_video_register()
 3) acpi_video_register registers the acpi_notifier for the hotkeys,
    and a backlight device
 4) acer-wmi loads, calls acpi_video_dmi_promote_vendor()
 5) calls acpi_video_unregister, this unregisters BOTH the acpi_notifier for
    the hotkeys AND the backlight device

And we end up without any handler for the brightness hotkeys. This patch fixes
this by switching over to acpi_video_unregister_backlight() which keeps the
hotkey handler in place.

8b48463f89 ACPI: Clean up inclusions of ACPI header files
Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.

First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds.  For CONFIG_ACPI set,
<linux/acpi.h> includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.

Second, there are ordering dependencies between those files that always
have to be met.  Namely, it is required that <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there.  And <acpi/acpi.h> which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds.  That also is taken care of including
<linux/acpi.h> as appropriate.

e6c33f1fe7 acer-wmi: support Lenovo ideapad S205 10382JG wifi switch
Found another Lenovo ideapad S205 the product name is 10382JG, it has
a 0x78 EC register exposes the state of wifi hardware switch on the machine.

So, add this patch to support Lenovo ideapad S205-10382JG wifi hardware
switch in acer-wmi driver.

Evidently the Ideapad S205 is just a model name on the market, but they have
totally different product name in DMI table.

b859f15921 Drivers: platform: x86: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
