Srinivas Pandruvada fb5b36a413 platform/x86: ISST: Add IOCTL to Translate Linux logical CPU to PUNIT CPU number
Add processing for IOCTL command ISST_IF_GET_PHY_ID. This converts from the
Linux logical CPU to PUNIT CPU numbering scheme.

Srinivas Pandruvada 8fbfb6fc67 platform/x86: ISST: Store per CPU information
There are two per CPU data needs to be stored and cached to avoid repeated
MSR readings for accessing them later:

- Physical to logical CPU conversion
The PUNIT uses a different CPU numbering scheme which is not APIC id based.
So we need to establish relationship between PUNIT CPU number and Linux
logical CPU numbering which is based on APIC id. There is an MSR 0x53
(MSR_THREAD_ID), which gets physical CPU number for the local CPU where it
is read. Also the CPU mask in some messages will inform which CPUs needs
to be online/offline for a TDP level. During TDP switch if user offlined
some CPUs, then the physical CPU mask can't be converted as we can't
read MSR on an offlined CPU to go to a lower TDP level by onlining more
CPUs. So the mapping needs to be established at the boot up time.

- Bus number corresponding to a CPU
A group of CPUs are in a control of a PUNIT. The PUNIT device is exported
as PCI device. To do operation on a PUNIT for a CPU, we need to find out
to which PCI device it is related to. This is done by reading MSR 0x128
(MSR_CPU_BUS_NUMBER).

So during CPU online stages the above MSRs are read and stored. Later
this stored information is used to process IOCTLs request from the user
space.

Srinivas Pandruvada 35f2c14d2a platform/x86: ISST: Add common API to register and handle ioctls
Encapsulate common functions which all Intel Speed Select Technology
interface drivers can use. This creates API to register misc device for
user kernel communication and handle all common IOCTLs. As part of the
registry it allows a callback which is to handle domain specific ioctl
processing.

There can be multiple drivers register for services, which can be built
as modules. So this driver handle contention during registry and as well
as during removal. Once user space opened the misc device, the registered
driver will be prevented from removal. Also once misc device is opened by
the user space new client driver can't register, till the misc device is
closed.

There are two types of client drivers, one to handle mail box interface
and the other is to allow direct read/write to some specific MMIO space.

This common driver implements IOCTL ISST_IF_GET_PLATFORM_INFO.

Yurii Pavlovskyi b096f626a6 platform/x86: asus-wmi: Switch fan boost mode
The WMI exposes a write-only device ID where up to three fan modes can be
switched on some laptops (TUF Gaming FX505GM). There is a hotkey
combination Fn-F5 that does have a fan icon, which is designed to toggle
between fan modes. The DSTS of the device ID returns information about the
presence of this capability and the presence of each of the two additional
fan modes as a bitmask (0x01 - overboost present, 0x02 - silent present)
[1].

Add a SysFS entry that reads the last written value and updates value in
WMI on write and a hotkey handler that toggles the modes taking into
account their availability according to DSTS.

Modes:
* 0x00 - normal or balanced,
* 0x01 - overboost, increased fan RPM,
* 0x02 - silent, decreased fan RPM

Yurii Pavlovskyi 1a373d15e2 platform/x86: asus-wmi: Support WMI event queue
Event codes are expected to be retrieved from a queue on at least some
models. Specifically, very likely the ACPI WMI devices with _UID ATK are
queued whereas those with ASUSWMI are not [1].

The WMI event codes are pushed into a circular buffer queue. After the INIT
method is called, ACPI code is allowed to push events into this buffer.
The INIT method cannot be reverted. If the module is unloaded and an event
(such as hotkey press) gets emitted before inserting it back the events get
processed delayed by one or if the queue overflows, additionally delayed by
about 3 seconds.

It might be considered a minor issue and no normal user would likely
observe this (there is little reason unloading the driver), but it does
significantly frustrate a developer who is unlucky enough to encounter
this. Therefore, the fallback to unqueued behavior occurs whenever
something unexpected happens.

The fix flushes the old key codes out of the queue on load. After receiving
event the queue is read until either ..FFFF or 1 is encountered. Also as
noted in [1] it is checked whether notify code is equal to 0xFF before
enabling queue processing in WMI notify handler.

DSDT examples:

FX505GM
Device (ATKD)
{ ..
    Name (ATKQ, Package (0x10)
    {
        0xFFFFFFFF, ..
    }

    Method (IANQ, 1, Serialized)
    {
        If ((AQNO >= 0x10))
        {
            Local0 = 0x64
            While ((Local0 && (AQNO >= 0x10)))
            {
                Local0--
                Sleep (0x0A)
            }
            ...
        ..
        AQTI++
        AQTI &= 0x0F
        ATKQ [AQTI] = Arg0
        ...
    }

    Method (GANQ, 0, Serialized)
    {
        ..
        If (AQNO)
        {
            ...
            Local0 = DerefOf (ATKQ [AQHI])
            AQHI++
            AQHI &= 0x0F
            Return (Local0)
        }

        Return (One)
    }

This code is almost identical to K54C, which does return Ones on empty
queue.

K54C:
Method (GANQ, 0, Serialized)
{
    If (AQNO)
    {
        ...
        Return (Local0)
    }

    Return (Ones)
}

Yurii Pavlovskyi e0668f2888 platform/x86: asus-wmi: Improve DSTS WMI method ID detection
The DSTS method detection mistakenly selects DCTS instead of DSTS if
nothing is returned when the method ID is not defined in WMNB. As a result,
the control of keyboard backlight is not functional for TUF Gaming series
laptops. Implement detection based on _UID of the WMI device instead.

There is evidence that DCTS is handled by ACPI WMI devices that have _UID
ASUSWMI, whereas none of the devices without ASUSWMI respond to DCTS and
DSTS is used instead [1].

DSDT examples:

FX505GM (_UID ATK):
Method (WMNB, 3, Serialized)
{ ...
    If ((Local0 == 0x53545344))
    {
        ...
        Return (Zero)
    }
    ...
    // No return
}

K54C (_UID ATK):
Method (WMNB, 3, Serialized)
{ ...
    If ((Local0 == 0x53545344))
    {
        ...
        Return (0x02)

Add a new function to acpi.h / wmi.c that returns _UID of the ACPI WMI

    Name (_HID, "PNP0C14" /* Windows Management Instrumentation Device */)
      // _HID: Hardware ID
    Name (_UID, "ATK")  // _UID: Unique ID
    ..

Generally, it is possible that multiple PNP0C14 ACPI devices are present in
the system as mentioned in the commit message of commit bff431e49f
("ACPI: WMI: Add ACPI-WMI mapping driver").

Therefore the _UID is returned for a specific ACPI device that declares the
given GUID, to which it is also mapped by other methods of wmi module.

Gaming series laptops producing multiple ACPI errors in the kernel log.

The input buffer for WMI method invocation size is 2 dwords, whereas
3 are expected by this model.

FX505GM:
..
Method (WMNB, 3, Serialized)
{
    P8XH (Zero, 0x11)
    CreateDWordField (Arg2, Zero, IIA0)
    CreateDWordField (Arg2, 0x04, IIA1)
    CreateDWordField (Arg2, 0x08, IIA2)
    Local0 = (Arg1 & 0xFFFFFFFF)
    ...

Compare with older K54C:
...
Method (WMNB, 3, NotSerialized)
{
    CreateDWordField (Arg2, 0x00, IIA0)
    CreateDWordField (Arg2, 0x04, IIA1)
    Local0 = (Arg1 & 0xFFFFFFFF)
    ...

Increase buffer size to 3 dwords. No negative consequences of this change
are expected, as the input buffer size is not verified. The original
function is replaced by a wrapper for a new method passing value 0 for the
last parameter. The new function will be used to control RGB keyboard
backlight.

Greg Kroah-Hartman d30cdc9a8a platform/x86: samsung-laptop: 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.

Vadim Pasternak fa882fc80d platform/x86: mlx-platform: Fix parent device in i2c-mux-reg device registration
Fix the issue found while running kernel with the option
CONFIG_DEBUG_TEST_DRIVER_REMOVE.
Driver 'mlx-platform' registers 'i2c_mlxcpld' device and then registers
few underlying 'i2c-mux-reg' devices:
	priv->pdev_i2c = platform_device_register_simple("i2c_mlxcpld", nr,
							 NULL, 0);
	...
	for (i = 0; i < ARRAY_SIZE(mlxplat_mux_data); i++) {
		priv->pdev_mux[i] = platform_device_register_resndata(
						&mlxplat_dev->dev,
						"i2c-mux-reg", i, NULL,
						0, &mlxplat_mux_data[i],
						sizeof(mlxplat_mux_data[i]));

But actual parent of "i2c-mux-reg" device is priv->pdev_i2c->dev and
not mlxplat_dev->dev.
Patch fixes parent device parameter in a call to
platform_device_register_resndata() for "i2c-mux-reg".

It solves the race during initialization flow while 'i2c_mlxcpld.1' is
removing after probe, while 'i2c-mux-reg.0' is still in probing flow:
'i2c_mlxcpld.1'	flow:	probe -> remove -> probe.

Commit 78f3ac76d9 ("platform/x86: asus-wmi: Tell the EC the OS will

on various EeePC laptop models using the eeepc-wmi driver (Asus EeePC
1015BX, Asus EeePC 1025C).

The asus_wmi_set_devstate(ASUS_WMI_DEVID_BACKLIGHT, 2, NULL) call added
by that commit is made conditional in this commit and only enabled in
the quirk_entry structs in the asus-nb-wmi driver fixing the broken
display / backlight on various EeePC laptop models.

on various EeePC laptop models using the eeepc-wmi driver (Asus EeePC
1015BX, Asus EeePC 1025C).

The asus_wmi_set_devstate(ASUS_WMI_DEVID_BACKLIGHT, 2, NULL) call added
by that commit is made conditional in this commit and only enabled in
the quirk_entry structs in the asus-nb-wmi driver fixing the broken

Pali Rohár 19b07cb4a1 i2c: i801: Register optional lis3lv02d I2C device on Dell machines
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 a7ae81952c ("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.

In ACPI, and now also in DT, the USB connectors usually have
their own device nodes. In case of USB Type-C, those
connector (port) nodes are child nodes of the controller or
PHY device, in our case the fusb302. The software fwnodes
allow us to create a similar child node for fusb302 that
represents the connector also on Intel CHT.

This makes it possible replace the fusb302 specific device
properties which were deprecated with the common USB
connector properties that tcpm.c is able to use directly.

Heikki Krogerus 3370db3519 usb: typec: Registering real device entries for the muxes
Registering real device entries (struct device) for the mode
muxes as well as for the orientation switches.

The Type-C mux code was deliberately attempting to avoid
creation of separate device entries for the orientation
switch and the mode switch (alternate modes) because they
are not physical devices. They are functions of a single
physical multiplexer/demultiplexer switch device.

Unfortunately because of the dependency we still have on the
underlying mux device driver, we had to put in hacks like
the one in the commit 3e3b81965c ("usb: typec: mux: Take
care of driver module reference counting") to make sure the
driver does not disappear from underneath us. Even with
those hacks we were still left with a potential NUll pointer
dereference scenario, so just creating the device entries,
and letting the core take care of the dependencies. No more
hacks needed.

Here is another set of reviewed patches that adds SPDX tags to different

 comments to try to determine that the license of the file is
 "GPL-2.0-or-later".  Only the "obvious" versions of these matches are
 included here, a number of "non-obvious" variants of text have been
 found but those have been postponed for later review and analysis.
 
 These patches have been out for review on the linux-spdx@vger mailing

Chris Chiu 487579bab8 platform/x86: asus-wmi: Add fn-lock mode switch support
Some of latest ASUS laptops support new fn-lock mode switching.
This commit detect whether if the fn-lock option is enabled in
BIOS setting, and toggle the fn-lock mode via a new WMI DEVID
0x00100023 when the corresponding notify code captured.

The ASUS fn-lock mode switch is activated by pressing Fn+Esc.
When on, keys F1 to F12 behave as applicable, with meanings
defined by the application being used at the time. When off,
F1 to F12 directly triggers hardware features, well known audio
volume up/down, brightness up/down...etc, which were triggered
by holding down Fn key and F-keys.

Because there's no way to retrieve the fn-lock mode via existing
WMI methods per ASUS spec, driver need to initialize and keep the
fn-lock mode by itself.

Hans de Goede 5105e78e5b platform/x86: ideapad-laptop: Remove no_hw_rfkill_list
When the ideapad-laptop driver was first written it was written for laptops
which had a hardware rfkill switch. So when the first ideapad laptops
showed up without a hw rfkill switch and it turned out that in this case
the ideapad firmware interface would always report the wifi being hardware-
blocked, a DMI id list of models which lack a hw rfkill switch was started
(by yours truly). Things were done this way to avoid regressing existing
models with a hw rfkill switch. In hindsight this was a mistake.

Lenovo releases a lot of ideapad models every year and even the latest
models still use the "VPC2004" ACPI interface the ideapad-laptop driver
binds to. Having a hw rfkill switch is quite rare on modern hardware, so
all these new models need to be added to the no_hw_rfkill_list, leading
to a never ending game of whack a mole.

Worse the failure mode when not present on the list, is very bad. In this
case the ideapad-laptop driver will report the wifi as being hw-blocked,
at which points NetworkManager does not even try to use it and the user
ends up with non working wifi.

This leads to various Linux fora on the internet being filled with
wifi not working on ideapad laptops stories, which does not make Linux
look good.

The failure mode when we flip the default to assuming that a hw rfkill
switch is not present OTOH is quite benign. When we properly report the
wifi as being hw-blocked on ideapads which do have the hw-switch; and it
is in the wifi-off position, then at least when using NetworkManager +
GNOME3 the user will get a "wifi disabled in hardware" message when trying
to connect to the wifi from the UI. If OTOH we assume there is no hardware
rfkill switch, then the user will get an empty list for the list of
available networks. Although the empty list vs the "wifi disabled in
hardware" message is a regression, it is a very minor regression and it
can easily be fixed on a model by model basis by filling the new
hw_rfkill_list this commit introduces.

Therefor this commit removes the ever growing no_hw_rfkill_list, flipping
the default to assuming there is no hw rfkill switch and adding a new
hw_rfkill_list. Thereby fixing the wifi not working on all the current
ideapad and yoga models which are not on the list yet and also fixing it
for all future ideapad and yoga models using the "VPC2004" ACPI interface.

Note once this patch has been accepted upstream. I plan to write a blog
post asking for users of ideapads and yoga's with a hw rfkill switch to
step forward, so that we can populate the new hw_rfkill_list with the few
older yoga and ideapad models which actually have a hw rfkill switch.

Andy Shevchenko af6c7e1ffc platform/x86: intel_pmc_ipc: Don't map non-used optional resources
The intel_pmc_ipc driver has a placeholder for all possible resources
that may have been provided by ACPI. Since there are few optional ones,
the driver still uses them and binds to wrong ranges in resource tree:

  # grep intel_punit_ipc /proc/iomem
  00000000-00000000 : intel_punit_ipc
    00000000-00000000 : intel_punit_ipc
      00000000-00000000 : intel_punit_ipc
        00000000-00000000 : intel_punit_ipc

This leads to issues with resource management during inserting and
removing modules, such as intel_pmc_ipc itself, which can't be inserted
anymore after first removal.

Count the actual resources provided and supply only them to the child device.

This is a real fix of the commit 8cc7fb4a65

  ("intel_pmc_ipc: update acpi resource structure for Punit")

that also fixes a symptoms described in the commit 6cc8cbbc88

  ("platform/x86: intel_punit_ipc: Fix resource ioremap warning")

that is going to be reverted afterwards.

Linus Torvalds 3601fe43e8 This is the bulk of GPIO changes for the v5.1 cycle:
Core changes:
 
 - The big change this time around is the irqchip handling in
   the qualcomm pin controllers, closely coupled with the
   gpiochip. This rework, in a classic fall-between-the-chairs
   fashion has been sidestepped for too long. The Qualcomm
   IRQchips using the SPMI and SSBI transport mechanisms have
   been rewritten to use hierarchical irqchip. This creates
   the base from which I intend to gradually pull support for
   hierarchical irqchips into the gpiolib irqchip helpers to
   cut down on duplicate code. We have too many hacks in the
   kernel because people have been working around the missing
   hierarchical irqchip for years, and once it was there,
   noone understood it for a while. We are now slowly adapting
   to using it. This is why this pull requests include changes
   to MFD, SPMI, IRQchip core and some ARM Device Trees
   pertaining to the Qualcomm chip family. Since Qualcomm have
   so many chips and such large deployments it is paramount
   that this platform gets this right, and now it (hopefully)
   does.
 
 - Core support for pull-up and pull-down configuration, also
   from the device tree. When a simple GPIO chip support a
   "off or on" pull-up or pull-down resistor, we provide a
   way to set this up using machine descriptors or device tree.
   If more elaborate control of pull up/down (such as
   resistance shunt setting) is required, drivers should be
   phased over to use pin control. We do not yet provide a
   userspace ABI for this pull up-down setting but I suspect
   the makers are going to ask for it soon enough. PCA953x
   is the first user of this new API.
 
 - The GPIO mockup driver has been revamped after some
   discussion improving the IRQ simulator in the process.
   The idea is to make it possible to use the mockup for
   both testing and virtual prototyping, e.g. when you do
   not yet have a GPIO expander to play with but really
   want to get something to develop code around before
   hardware is available. It's neat. The blackbox testing
   usecase is currently making its way into kernelci.
 
 - ACPI GPIO core preserves non direction flags when updating
   flags.
 
 - A new device core helper for devm_platform_ioremap_resource()
   is funneled through the GPIO tree with Greg's ACK.
 
 New drivers:
 
 - TQ-Systems QTMX86 GPIO controllers (using port-mapped
   I/O)
 
 - Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
 
 - AMD G-Series PCH (Platform Controller Hub) GPIO driver.
 
 - Fintek F81804 & F81966 subvariants.
 
 - PCA953x now supports NXP PCAL6416.
 
 Driver improvements:
 
 - IRQ support on the Nintendo Wii (Hollywood) GPIO.
 
 - get_direction() support for the MVEBU driver.
 
 - Set the right output level on SAMA5D2.
 
 - Drop the unused irq trigger setting on the Spreadtrum
   driver.
 
 - Wakeup support for PCA953x.
 
 - A slew of cleanups in the various Intel drivers.

Rajneesh Bhardwaj 238f9c1135 platform/x86: intel_pmc_core: Quirk to ignore XTAL shutdown
On some platforms such as HP Elite-x2-1013-g3, the platform BIOS
enforces XTAL to remain off before S0ix state can be achieved. This may
not be optimum when we want to enable use cases like Low Power Audio,
Wake on Voice etc which always need 24mhz clock.

This introduces a new quirk to allow S0ix entry when all other
conditions except for XTAL clock are good on a given platform. The extra
power consumed by XTAL clock is about 2mw but it saves much more
platform power compared to the system that remains in just PC10.

Rajneesh Bhardwaj 8aba056a4e platform/x86: intel_pmc_core: Add Package cstates residency info
This patch introduces a new debugfs entry to read current Package
cstate residency counters. A similar variant of this patch was discussed
earlier "https://patchwork.kernel.org/patch/9908563/" but didn't make it
into mainline for various reasons. Current version only adds debugfs
entry which is quite useful for S0ix debug but excludes the exported API
that was there in initial version. Though there are tools like turbostat
and socwatch which can also show this info but sometimes its more
practical to have it here as it's hard to switch between various tools for
S0ix debug when pmc_core driver is the primary debug tool. Internal and
external customers have requested for this patch to be included in the
PMC driver on many occasions and Google Chrome OS team has already included
it in their builds. This becomes handy when requesting logs from external
customers who may not always have above mentioned tools in their integrated
kernel builds.

Package cstate residency MSRs provide useful debug information about
system idle states. In idle states system must enter deeper Package
cstates. Package cstates depend not only on Core cstates but also on
various IP block's power gating status and LTR values.

For Intel Core SoCs Package C10 entry is a must for deeper sleep states
such as S0ix. "Suspend-to-idle"  should ideally take this path:
PC0 -> PC10 -> S0ix. For S0ix debug, its logical to check for
Package C10 residency first if for some reason system fails to enter S0ix.

Please refer to this link for MSR details:
https://software.intel.com/sites/default/files/managed/22/0d/335592-sdm-vol-4.pdf

Usage:
cat /sys/kernel/debug/pmc_core/package_cstate_show

Commit ae7c8cba32 ("platform/x86: ideapad-laptop: add lenovo RESCUER
R720-15IKBN to no_hw_rfkill_list") added
    DMI_MATCH(DMI_BOARD_NAME, "80WW")
for Lenovo RESCUER R720-15IKBN.

But DMI_BOARD_NAME does not match 80WW on Lenovo RESCUER R720-15IKBN,
thus cause Wireless LAN still be hard blocked.

On Lenovo RESCUER R720-15IKBN:
    ~$ cat /sys/class/dmi/id/sys_vendor
    LENOVO
    ~$ cat /sys/class/dmi/id/board_name
    Provence-5R3
    ~$ cat /sys/class/dmi/id/product_name
    80WW
    ~$ cat /sys/class/dmi/id/product_version
    Lenovo R720-15IKBN

So on Lenovo RESCUER R720-15IKBN:
    DMI_SYS_VENDOR should match "LENOVO",
    DMI_BOARD_NAME should match "Provence-5R3",
    DMI_PRODUCT_NAME should match "80WW",
    DMI_PRODUCT_VERSION should match "Lenovo R720-15IKBN".

Fix it, and in according with other entries in no_hw_rfkill_list,
use DMI_PRODUCT_VERSION instead of DMI_BOARD_NAME.

Hans de Goede c994611aca platform/x86: asus-wmi: Allow loading on systems without the Asus Management GUID
hid-asus depends on asus-wmi through the asus_wmi_evaluate_method. Before
this commit asus-wmi, and thus hid-asus, could not be loaded on non-Asus
systems. This breaks using Asus bluetooth keyboards such as the Asus
T100CHI keyboard with non Asus systems.

This commit fixes this by allowing asus-wmi to load on systems without the
Asus Management GUID.

This is safe to do since all asus-wmi sub drivers use
asus_wmi_register_driver which also checks for the GUID.

This commit also improves the error messages in asus_wmi_register_driver
to include "ASUS" in their description to make them more clear. This is
important since we now rely on those errors when loaded on systems without
the Asus Management GUID.

but it is needed for the consumers of "ltr_ignore" as the index printing
for "ltr_show" is missing. For example, w/o this change, a user that wants
to ignore LTR from ME would do something like

echo 5 > ltr_ignore

but the index for ME is 6. Printing a reserved IP helps to properly

family agnostic <c977b98bbef5898ed3d30b08ea67622e9e82082a>" provided

e.g. the following condition

for (index = 0; index < pmcdev->map->ppfear_buckets &&
	index < PPFEAR_MAX_NUM_ENTRIES; index++, iter++)

is wrong because for CNL, PPFEAR_MAX_NUM_ENTRIES is hardcoded as 5 which
is _wrong_ and even though ppfear_buckets is 8, the loop fails to read
all eight registers needed for CNL PCH i.e. PPFEAR0 and PPFEAR1. This
patch refactors the pfear show logic to correctly read PCH IP power
gating status for Cannonlake and beyond.

The ACPI firmware node actually contains 3 I2cSerialBusV2 resources,
but this seems to be a copy and paste job from the BSG1160 firmware node
on other devices, since there is no i2c-client listening to the 0x68
address listed in the third resource and the 0x68 address is identical
to the address of the third resource in the BSG1160 nodes, where as the
other 2 addresses are different.

Add the ID to the I2C multi instantiate list, so that the
i2c-multi-instantiate.c driver can handle it;

And add the necessary info to the i2c-multi-instantiate.c driver to
enumerate all I2C slaves correctly.

To avoid triggering the:

Jérôme de Bretagne e97a34563d platform/x86: intel-hid: Missing power button release on some Dell models
Power button suspend for some Dell models was added in:

commit 821b853662 ("platform/x86: intel-hid: Power button suspend on Dell Latitude 7275")

by checking against the power button press notification (0xCE) to report
the power button press event. The corresponding power button release
notification (0xCF) was caught and ignored to stop it from being reported
as an "unknown event" in the logs.

The missing button release event is creating issues on Android-x86, as
reported on the project mailing list for a Dell Latitude 5175 model, since
the events are expected in down/up pairs.

Report the power button release event to fix this issue.

Linus Torvalds 457fa3469a Char/Misc driver patches for 4.21-rc1
Here is the big set of char and misc driver patches for 4.21-rc1.
 
 Lots of different types of driver things in here, as this tree seems to
 be the "collection of various driver subsystems not big enough to have
 their own git tree" lately.
 
 Anyway, some highlights of the changes in here:
   - binderfs: is it a rule that all driver subsystems will eventually
     grow to have their own filesystem?  Binder now has one to handle the
     use of it in containerized systems.  This was discussed at the
     Plumbers conference a few months ago and knocked into mergable shape
     very fast by Christian Brauner.  Who also has signed up to be
     another binder maintainer, showing a distinct lack of good judgement :)
   - binder updates and fixes
   - mei driver updates
   - fpga driver updates and additions
   - thunderbolt driver updates
   - soundwire driver updates
   - extcon driver updates
   - nvmem driver updates
   - hyper-v driver updates
   - coresight driver updates
   - pvpanic driver additions and reworking for more device support
   - lp driver updates.  Yes really, it's _finally_ moved to the proper
     parallal port driver model, something I never thought I would see
     happen.  Good stuff.
   - other tiny driver updates and fixes.
 
 All of these have been in linux-next for a while with no reported

Ayman Bagabas bf4fb28c6e platform/x86: add support for Huawei WMI hotkeys
This driver adds support for missing hotkeys on some Huawei laptops.
Laptops such as the Matebook X have non functioning hotkeys. Whereas
newer laptops such as the Matebook X Pro come with working hotkeys out
of the box.

Old laptops, such as the Matebook X, report hotkey events through ACPI
device "\WMI0". However, new laptops, such as the Matebook X Pro, does
not have this WMI device.

All the hotkeys on the Matebook X Pro work fine without this patch
except (micmute, wlan, and huawei key). These keys and the brightness
keys report events to "\AMW0" ACPI device. One problem is that
brightness keys on the Matebook X Pro work without this patch. This
results in reporting two brightness key press events one is captured
by ACPI and another by this driver.

A solution would be to check if such event came from the "\AMW0" WMI
driver then skip reporting event. Another solution would be to leave
this to user-space to handle. Which can be achieved by using "hwdb"
tables and remap those keys to "unknown". This solution seems more
natural to me because it leaves the decision to user-space.

This fix is necessary, because register used before for tachometer 7
has been than reserved for the second PWM for newer systems, which are
not supported yet in mlx-platform driver. So registers of tachometers

Ville Syrjälä 6a31061833 platform/x86: Fix config space access for intel_atomisp2_pm
We lose even config space access when we power gate the ISP
via the PUNIT. That makes lspci & co. produce gibberish.

To fix that let's try to implement actual runtime pm hooks
and inform the pci core that the device always goes to
D3cold. That will cause the pci core to resume the device
before attempting config space access.

This introduces another annoyance though. We get the
following error every time we try to resume the device:
intel_atomisp2_pm 0000:00:03.0: Refused to change power state, currently in D3

The reason being that the pci core tries to put the device
back into D0 via the standard PCI PM mechanism before
calling the driver resume hook. To fix this properly
we'd need to infiltrate the platform pm hooks (could
turn ugly real fast), or use pm domains (which don't
seem to exist on x86), or some extra early resume
hook for the driver (which doesn't exist either).
So maybe we just choose to live with the error?

Takashi Iwai 4e1d092445 platform/x86: thinkpad_acpi: Add audio mute LED classdev support
In the upcoming change, the binding of audio mute / mic-mute LED
controls will be switched with LED trigger.  This patch is the last
piece of preparation: adding the audio mute / mic-mute LED class
devices to thinkpad_acpi driver.

Two devices, platform::mute and platform::micmute, will be added for
controlling the mute LED and mic-mute LED, respectively.  The new
prefix "platform" is the suggestion by upstream for indicating the
generic laptop attribute.

Also this selects CONFIG_LEDS_TRIGGERS and CONFIG_LEDS_TRIGGERS_AUDIO
unconditionally.  Strictly speaking, these aren't 100% mandatory, but
leaving these manual selections would lead to a functional regression
easily once after converting from the dynamic symbol binding to the
LEDs trigger in a later patch.

As of this patch, the LED device isn't tied with the audio driver, and
can be changed via user-space at "platform::micmute" sysfs entry.
(This new prefix "platform" is the agreement among people for
indicating the generic laptop / system-wide attribute.)

The binding with HD-audio is still done via the existing exported
dell_micmute_led_set().  It will be replaced with the LED trigger
binding in later patches.

Also this selects CONFIG_LEDS_TRIGGERS and CONFIG_LEDS_TRIGGERS_AUDIO

When the OS registers to handle events from the display off hotkey the
EC will send a notification with 0x35 for every key press, independent
of the backlight state.

The behavior of this key on Windows, with the ATKACPI driver from Asus
installed, is turning off the backlight of all connected displays with a
fading effect, and any cursor input or key press turning the backlight
back on. The key press or cursor input that wakes up the display is also
passed through to the application under the cursor or under focus.

The key that matches this behavior the closest is KEY_SCREENLOCK.

João Paulo Rechi Vita 78f3ac76d9 platform/x86: asus-wmi: Tell the EC the OS will handle the display off hotkey
In the past, Asus firmwares would change the panel backlight directly
through the EC when the display off hotkey (Fn+F7) was pressed, and
only notify the OS of such change, with 0x33 when the LCD was ON and
0x34 when the LCD was OFF. These are currently mapped to
KEY_DISPLAYTOGGLE and KEY_DISPLAY_OFF, respectively.

Most recently the EC on Asus most machines lost ability to toggle the
LCD backlight directly, but unless the OS informs the firmware it is
going to handle the display toggle hotkey events, the firmware still
tries change the brightness through the EC, to no effect. The end result
is a long list (at Endless we counted 11) of Asus laptop models where
the display toggle hotkey does not perform any action. Our firmware
engineers contacts at Asus were surprised that there were still machines
out there with the old behavior.

Calling WMNB(ASUS_WMI_DEVID_BACKLIGHT==0x00050011, 2) on the _WDG device
tells the firmware that it should let the OS handle the display toggle
event, in which case it will simply notify the OS of a key press with
0x35, as shown by the DSDT excerpts bellow.

Zhang Xianwei 8055db3a5b platform/x86: thinkpad_acpi: Change the keymap for Favorites hotkey
The keycode KEY_FAVORITES(0x16c) used in thinkpad_acpi driver is too
big (out of range > 255) for xorg to handle.
xkeyboard-config has already mapped KEY_BOOKMARKS(156) to
XF86Favorites:

keycodes/evdev:
    <I164> = 164;   // #define KEY_BOOKMARKS           156

symbols/inet:
    key <I164>   {      [ XF86Favorites         ]       };

So change the keymap to KEY_BOOKMARKS for Favorites hotkey.
