Andy Shevchenko 85624f90c8 platform/x86: asus-wmi: Make it depend on ACPI battery API
When driver has been switched to use ACPI battery API in the commit

  7973353e92 ("Refactor charge threshold to use the battery hooking API")

it makes it implicitly dependent to a corresponding kernel configuration
option.

Make this dependency explicit in Kconfig.

Linus Torvalds 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.
 
 The listed below commits are duplicated due to previously pushed fixes in v5.2 cycle:
 - 1dd93f873d platform/x86: asus-wmi: Only Tell EC the OS will handle display hotkeys from asus_nb_wmi

Linus Torvalds 97ff4ca46d Char / Misc driver patches for 5.3-rc1
Here is the "large" pull request for char and misc and other assorted
 smaller driver subsystems for 5.3-rc1.
 
 It seems that this tree is becoming the funnel point of lots of smaller
 driver subsystems, which is fine for me, but that's why it is getting
 larger over time and does not just contain stuff under drivers/char/ and
 drivers/misc.
 
 Lots of small updates all over the place here from different driver
 subsystems:
   - habana driver updates
   - coresight driver updates
   - documentation file movements and updates
   - Android binder fixes and updates
   - extcon driver updates
   - google firmware driver updates
   - fsi driver updates
   - smaller misc and char driver updates
   - soundwire driver updates
   - nvmem driver updates
   - w1 driver fixes
 
 All of these have been in linux-next for a while with no reported

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.

Some function keys on the built in keyboard on Xiaomi's notebooks does
not produce any key events when pressed in combination with the function
key. Some of these keys do report that they are being pressed via WMI
events.

This driver reports key events for Fn+F7 and double tap on Fn.

Other WMI events that are reported by the hardware but not utilized by
this driver are Caps Lock(which already work) and Fn lock/unlock.

warning: unmet direct dependencies detected for BACKLIGHT_CLASS_DEVICE.

ACPI_CMPC selects BACKLIGHT_CLASS_DEVICE but BACKLIGHT_CLASS_DEVICE
depends on BACKLIGHT_LCD_SUPPORT.

Copy BACKLIGHT_LCD_SUPPORT dependency into ACPI_CMPC to fix

WARNING: unmet direct dependencies detected for BACKLIGHT_CLASS_DEVICE

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.

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.

Takashi Iwai d00fa46e0a platform/x86: dell-laptop: Add micmute LED trigger support
This patch adds the LED trigger support for audio mic-mute control.
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
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

Hans de Goede 49ad712afa platform/x86: Add Intel AtomISP2 dummy / power-management driver
The Image Signal Processor found on Cherry Trail devices is brought up in
D0 state on devices which have camera sensors attached to it. The ISP will
not enter D3 state again without some massaging of its registers beforehand
and the ISP not being in D3 state blocks the SoC from entering S0ix modes.

There was a driver for the ISP in drivers/staging but that got removed
again because it never worked. It does not seem likely that a real
driver for the ISP will be added to the mainline kernel anytime soon.

This commit adds a dummy driver which contains the necessary magic from
the staging driver to powerdown the ISP, so that Cherry Trail devices where
the ISP is used will properly use S0ix modes when suspended.

Together with other recent S0ix related fixes this allows S0ix modes to
be entered on e.g. a Chuwi Hi8 Pro and a HP x2 210.

Linus Torvalds 899fbc33fd platform-drivers-x86 for v4.19-1
The driver for Silead touchscreen configurations has been renamed
 from silead_dmi to touchscreen_dmi since it starts supporting other
 touchscreens which require some DMI quirks. At the same release cycle
 it gets expanded to cover cases for Chuwi Vi10, ONDA V891W,
 Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets.
 
 Another bunch of changes is related to Mellanox platform code to allow
 user space to communicate with Mellanox for system control and
 monitoring purposes. The driver notifies user on hotplug device signal
 receiving.
 
 ASUS WMI drivers recognize lid flip action on UX360, and correctly
 toggles airplane mode LED. In addition the keyboard backlight toggle
 gets support.
 
 ThinkPad ACPI driver enables support for calculator key (on at least P52).
 It also has been fixed to support three characters model designators,
 which are used for modern laptops. Earlier the battery, marked as BAT1,
 on ThinkPad laptops has not been configured properly, which is fixed.
 On the opposite the multi-battery configurations now probed correctly.
 
 Dell SMBIOS driver starts working on some Dell servers which do not
 support token interface. The regression with backlight detection has
 also been fixed. In order to support dock mode on some laptops,
 Intel virtual button driver has been fixed. The last but not least
 is the fix to Intel HID driver due to changes in Dell systems that
 prevented to use power button.

Merge tag 'platform-drivers-x86-v4.19-1' of git://git.infradead.org/linux-platform-drivers-x86

Pull x86 platform driver updates from Andy Shevchenko:

 - The driver for Silead touchscreen configurations has been renamed
   from silead_dmi to touchscreen_dmi since it starts supporting other
   touchscreens which require some DMI quirks

   It also gets expanded to cover cases for Chuwi Vi10, ONDA V891W,
   Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets.

 - Another bunch of changes is related to Mellanox platform code to
   allow user space to communicate with Mellanox for system control and
   monitoring purposes. The driver notifies user on hotplug device
   signal receiving.

 - ASUS WMI drivers recognize lid flip action on UX360, and correctly
   toggles airplane mode LED. In addition the keyboard backlight toggle
   gets support.

 - ThinkPad ACPI driver enables support for calculator key (on at least
   P52). It also has been fixed to support three characters model
   designators, which are used for modern laptops. Earlier the battery,
   marked as BAT1, on ThinkPad laptops has not been configured properly,
   which is fixed. On the opposite the multi-battery configurations now
   probed correctly.

 - Dell SMBIOS driver starts working on some Dell servers which do not
   support token interface. The regression with backlight detection has
   also been fixed. In order to support dock mode on some laptops, Intel
   virtual button driver has been fixed. The last but not least is the
   fix to Intel HID driver due to changes in Dell systems that prevented
   to use power button.

Hans de Goede e64e84987d platform/x86: Add ACPI i2c-multi-instantiate pseudo driver
On systems with ACPI instantiated i2c-clients, normally there is 1 fw_node
per i2c-device and that fw-node contains 1 I2cSerialBus resource for that 1
i2c-device.

But in some rare cases the manufacturer has decided to describe multiple
i2c-devices in a single ACPI fwnode with multiple I2cSerialBus resources.

An earlier attempt to fix this in the i2c-core resulted in a lot of extra
code to support this corner-case.

This commit introduces a new i2c-multi-instantiate driver which fixes this
in a different way. This new driver can be built as a module which will
only loaded on affected systems.

This driver will instantiate a new i2c-client per I2cSerialBus resource,
using the driver_data from the acpi_device_id it is binding to to tell it
which chip-type (and optional irq-resource) to use when instantiating.

Note this driver depends on a platform device being instantiated for the
ACPI fwnode, see the i2c_multi_instantiate_ids list of ACPI device-ids in
drivers/acpi/scan.c: acpi_device_enumeration_by_parent().

Hans de Goede 74421786f0 platform/x86: Rename silead_dmi to touchscreen_dmi
Not only silead touchscreens need some extra info not available in the
ACPI tables to work properly. X86 devices with a Chipone ICN8505 chip also
need some DMI based extra configuration.

There is no reason to have separate dmi config code per touchscreen
controller vendor. This commit renames silead_dmi to a more generic
touchscreen_dmi name (and Kconfig option) in preparation of adding
info for tablets with an ICN8505 based touchscreen.

Note there are no functional changes all code changes are limited to
removing references to silead where these are no longer applicable.

Vadim Pasternak ef0f62264b platform/x86: mlx-platform: Add physical bus number auto detection
mlx-platform does not provide a bus number to i2c-mlxcpld, assuming it
is always one. On some x86 systems, other i2c drivers may probe before
i2c-mlxcpld, causing bus one to be busy.

Make mlx-platform determine which adapter number is free prior to
activating i2c-mlxpld, adjusting the mux base numbers accordingly.
Update the mlxreg-hotplug pdata similarly.

This adds an explicit mlx-platform build dependency on I2C, update the
Kconfig accordingly. Add the missing REGMAP dependency while we're at
it.

Darren Hart (VMware) 32d7b19bad platform/x86: dell-smbios: Resolve dependency error on DCDBAS
When the DELL_SMBIOS_SMM backend is enabled, the DELL_SMBIOS symbol
depends on DELL_DCDBAS, and we must avoid the situation where
DELL_SMBIOS=y and DCDBAS=m.

Adding the conditional dependency to DELL_SMBIOS such as:

depends !DELL_SMBIOS_SMM || (DCDBAS || DCDBAS=n)

results in the Kconfig tooling complaining about a circular dependency,
although it appears to work in practice.

Avoid the errors by simplifying the dependency and forcing DELL_SMBIOS
to be <= DCDBAS if DCDBAS is enabled (thanks to Greg KH for the
suggestion).

Darren Hart (VMware) 329d58b890 platform/x86: Allow for SMBIOS backend defaults
Avoid accidental configurations by setting default y for DELL_SMBIOS
backends. Avoid this impacting the default build size, by making them
dependent on DELL_SMBIOS, so they only appear when DELL_SMBIOS is
manually selected, or by DELL_LAPTOP or DELL_WMI.

While DELL_SMBIOS does have a prompt, it does not have any dependencies.
Keeping DELL_SMBIOS visible, despite being "select"ed by DELL_LAPTOP and
DELL_WMI, is a deliberate choice to provide context for the WMI and SMM
backends, which would otherwise appear to float without context within
the menu.

Some race conditions were raised due to dell-smbios and its backends
not being ready by the time that a consumer would call one of the
exported methods.

To avoid this problem, guarantee that all initialization has been
done by linking them all together and running init for them all.

As part of this change the Kconfig needs to be adjusted so that
CONFIG_DELL_SMBIOS_SMM and CONFIG_DELL_SMBIOS_WMI are boolean
rather than modules.

CONFIG_DELL_SMBIOS is a visually selectable option again and both
CONFIG_DELL_SMBIOS_WMI and CONFIG_DELL_SMBIOS_SMM are optional.

Darren Hart (VMware) cc69c88fbe platform/x86: dell-smbios: Resolve dependency error on DCDBAS
When the DELL_SMBIOS_SMM backend is enabled, the DELL_SMBIOS symbol
depends on DELL_DCDBAS, and we must avoid the situation where
DELL_SMBIOS=y and DCDBAS=m.

Adding the conditional dependency to DELL_SMBIOS such as:

depends !DELL_SMBIOS_SMM || (DCDBAS || DCDBAS=n)

results in the Kconfig tooling complaining about a circular dependency,
although it appears to work in practice.

Avoid the errors by simplifying the dependency and forcing DELL_SMBIOS
to be <= DCDBAS if DCDBAS is enabled (thanks to Greg KH for the
suggestion).

Darren Hart (VMware) c715e43455 platform/x86: Allow for SMBIOS backend defaults
Avoid accidental configurations by setting default y for DELL_SMBIOS
backends. Avoid this impacting the default build size, by making them
dependent on DELL_SMBIOS, so they only appear when DELL_SMBIOS is
manually selected, or by DELL_LAPTOP or DELL_WMI.

While DELL_SMBIOS does have a prompt, it does not have any dependencies.
Keeping DELL_SMBIOS visible, despite being "select"ed by DELL_LAPTOP and
DELL_WMI, is a deliberate choice to provide context for the WMI and SMM
backends, which would otherwise appear to float without context within
the menu.
