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.

Just like we avoid specifying actual block devices like sda for fdisk
and dd examples, we should not specify specific thermal zones here.

On the platform I was testing on, zone0 was acpitz, and zone1 was for
this acerhdf driver.  Make the printk such that it won't work with a
blind cut-and-paste, and force the user to determine which zone is
correct for this driver.

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.

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().

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.

 The fujitsu-laptop driver is cleaned up and now supports hotkeys for
 Lifebook U7x7 models. Besides that the typo introduced by one of
 previous clean up series has been fixed.
 
 Specific to x86-based laptops HID device now supports
 KEY_ROTATE_LOCK_TOGGLE event which is emitted, for example,
 by Wacom MobileStudio Pro 13.
 
 Turbo MAX 3 technology is enabled for the rest of platforms that support
 Hardware-P-States feature which have core priority described by
 ACPI CPPC table.
 
 Mellanox on x86 gets better support of I2C bus in use including support
 of hotpluggable ones.
 
 Silead touchscreen is enabled on two tablet models, i.e Yours Y8W81 and
 I.T.Works TW701.
 
 From now on the second fan on Thinkpad P50 is supported.
 
 The topstar-laptop driver is reworked to support new models, in
 particular Topstar U931.
 
 Some of the changes had been already applied during v4.16 cycle and thus
 have a duplication here:

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.

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).

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.

bf8f65da31 platform/x86: topstar-laptop: add Topstar U931/RVP7 WLAN LED workaround
Topstar U931 laptops provide a LED synced with the WLAN adapter
hard-blocking state. Unfortunately, some models seem to be defective,
making impossible to hard-block the adapter with the WLAN switch and
thus the LED is useless.

An ACPI method is available to programmatically control this switch and
it indirectly allows to control the LED.

This commit registers the LED within the corresponding subsystem, making
possible for instance to use an rfkill-based trigger to synchronize the
LED with the device state.

This workaround is enabled automatically for Topstar U931/RVP7 laptops
based on a DMI check.

Drivers should not 'select' a subsystem. Instead they should depend
on it. If the subsystem is disabled, the user probably did that for
a purpose and one driver shouldn't be changing that.

This also makes all platform/x86/ drivers consistent w.r.t depending on
INPUT instead of selecting it.

New Acer laptops in 2018 will have a separate ACPI device for
notifications from the airplane mode hotkey. The device name in
the DSDT is SMKB and its ACPI _HID is 10251229.

For these models, when the airplane mode hotkey (Fn+F3) pressed,
a query 0x02 is started in the Embedded Controller, and all this
query does is a notify SMKB with the value 0x80.

        Scope (_SB.PCI0.LPCB.EC0)

07c455ee22 platform-drivers-x86 for v4.15-1
For this cycle we have quite an update for the Dell SMBIOS driver
 including WMI work to provide an interface for SMBIOS tokens via sysfs
 and WMI support for 2017+ Dell laptop models. SMM dispatcher code is
 split into a separate driver followed by a new WMI dispatcher.
 The latter provides a character device interface to user space.
 
 The pull request contains a merge of immutable branch from Wolfram Sang
 in order to apply a dependent fix to the Intel CherryTrail Battery
 Management driver.
 
 Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0
 support is added for Intel Skylake.
 
 Peaq WMI hotkeys driver gets its own maintainer and white list of
 supported models.
 
 Silead DMI is expanded to support few additional platforms.
 
 Tablet mode via GMMS ACPI method is added to support some ThinkPad
 tablets.

Pull x86 platform driver updates from Andy Shevchenko:
 "Here is the collected material against Platform Drivers x86 subsystem.
  It's rather bit busy cycle for PDx86, mostly due to Dell SMBIOS driver
  activity

  For this cycle we have quite an update for the Dell SMBIOS driver
  including WMI work to provide an interface for SMBIOS tokens via sysfs
  and WMI support for 2017+ Dell laptop models. SMM dispatcher code is
  split into a separate driver followed by a new WMI dispatcher. The
  latter provides a character device interface to user space.

  The git history also contains a merge of immutable branch from Wolfram
  Sang in order to apply a dependent fix to the Intel CherryTrail
  Battery Management driver.

  Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0
  support is added for Intel Skylake.

  Peaq WMI hotkeys driver gets its own maintainer and white list of
  supported models.

  Silead DMI is expanded to support few additional platforms.

1a258e6704 platform/x86: dell-smbios-wmi: Add new WMI dispatcher driver
The dell-smbios stack only currently uses an SMI interface which grants
direct access to physical memory to the firmware SMM methods via a pointer.

This dispatcher driver adds a WMI-ACPI interface that is detected by WMI
probe and preferred over the SMI interface in dell-smbios.

Changing this to operate over WMI-ACPI will use an ACPI OperationRegion
for a buffer of data storage when SMM calls are performed.

This is a safer approach to use in kernel drivers as the SMM will
only have access to that OperationRegion.

549b4930f0 platform/x86: dell-smbios: Introduce dispatcher for SMM calls
This splits up the dell-smbios driver into two drivers:
* dell-smbios
* dell-smbios-smm

dell-smbios can operate with multiple different dispatcher drivers to
perform SMBIOS operations.

Also modify the interface that dell-laptop and dell-wmi use align to this
model more closely.  Rather than a single global buffer being allocated
for all drivers, each driver will allocate and be responsible for it's own
buffer. The pointer will be passed to the calling function and each
dispatcher driver will then internally copy it to the proper location to
perform it's call.

Add defines for calls used by these methods in the dell-smbios.h header
for tracking purposes.

92b8c540bc platform/x86: dell-wmi-descriptor: split WMI descriptor into it's own driver
All communication on individual GUIDs should occur in separate drivers.
Allowing a driver to communicate with the bus to another GUID is just
a hack that discourages drivers to adopt the bus model.

The information found from the WMI descriptor driver is now exported
for use by other drivers.

455e027f33 platform/x86: intel_cht_int33fe: Update fusb302 type string, add properties
The fusb302 driver as merged in staging uses "typec_fusb302" as i2c-id
rather then just "fusb302" and needs us to set a number of device-
properties, adjust the intel_cht_int33fe driver accordingly.

One of the properties set is max-snk-mv which makes the fusb302 driver
negotiate up to 12V charging voltage, which is a bad idea on boards
which are not setup to handle this, so this commit also adds 2 extra
sanity checks to make sure that the expected Whiskey Cove PMIC +
TI bq24292i charger combo, which can handle 12V, is present.

ce6a90027c platform/x86: Add driver to force WMI Thunderbolt controller power status
Current implementations of Intel Thunderbolt controllers will go
into a low power mode when not in use.

Many machines containing these controllers also have a GPIO wired up
that can force the controller awake.  This is offered via a ACPI-WMI
interface intended to be manipulated by a userspace utility.

This mechanism is provided by Intel to OEMs to include in BIOS.
It uses an industry wide GUID that is populated in a separate _WDG
entry with no binary MOF.

This interface allows software such as fwupd to wake up thunderbolt
controllers to query the firmware version or flash new firmware.

eee77da1a7 platform/x86: fujitsu-laptop: rework debugging
Using a dedicated Kconfig option for enabling debugging means the user
may be forced to recompile their kernel in order to gather debugging
information, which is inconvenient.  Replace custom debugging
infrastructure with standard logging functions, taking advantage of
dynamic debug.  Replace a pr_info() call inside an ACPI callback with an
acpi_handle_info() call.

The following mapping was used:

  - FUJLAPTOP_DBG_ERROR -> acpi_handle_err()
  - FUJLAPTOP_DBG_WARN  -> acpi_handle_info() / dev_info()
  - FUJLAPTOP_DBG_INFO  -> acpi_handle_debug()
  - FUJLAPTOP_DBG_TRACE -> acpi_handle_debug() / dev_dbg()

This means that some events which used to only be logged when the user
explicitly requested it will now be logged by default:

  - ACPI method evaluation errors,
  - unknown ACPI notification codes,
  - unknown hotkey scancodes.

The first type of events should happen rarely, if ever at all.  The rest
is interesting from driver development perspective as their presence in
the logs will mean the driver is unaware of certain events, handling of
which should be implemented.

63dada87f7 platform/x86: Add driver for ACPI INT0002 Virtual GPIO device
Some peripherals on Bay Trail and Cherry Trail platforms signal a
Power Management Event (PME) to the Power Management Controller (PMC)
to wakeup the system. When this happens software needs to explicitly
clear the PME bus 0 status bit in the GPE0a_STS register to avoid an
IRQ storm on IRQ 9.

This is modelled in ACPI through the INT0002 ACPI device, which is
called a "Virtual GPIO controller" in ACPI because it defines the
event handler to call when the PME triggers through _AEI and _L02
methods as would be done for a real GPIO interrupt in ACPI.

This commit adds a driver which registers the Virtual GPIOs expected
by the DSDT on these devices, letting gpiolib-acpi claim the
virtual GPIO and install a GPIO-interrupt handler which call the _L02
handler as it would for a real GPIO controller.

f9dd82c0ea platform/x86: wmi-bmof: New driver to expose embedded Binary WMI MOF metadata
Many laptops (and maybe servers?) have embedded WMI Binary MOF metadata.
We do not yet have open-source tools for processing the data, although
one is in the works thanks to Pali:

	https://github.com/pali/bmfdec

There is currently no interface to get the data in the first place. By
exposing it, we facilitate the development of new tools.

This is based on the original work of Andy Lutomirski <luto@kernel.org>,
but contains several modifications in response to various reviews.
