Add support to ideapad-laptop for Lenovo platforms that have DYTC
version 5 support or newer to use the platform profile feature.
Mostly based on Mark Pearson <markpearson@lenovo.com>'s thinkpad-acpi
work but massaged to fit ideapad driver.
Note that different from ThinkPads, IdeaPads's Thermal Hotkey won't
trigger profile switch itself, we'll leave it for userspace programs.
Tested on Lenovo Yoga-14S ARE Chinese Edition.

There are no bugs or problems ever reported outside from Intel

The ACPI-enabled Intel MID platforms neither have WDAT table nor proper IDs
to instantiate watchdog device. In order to keep them working move the board
code from arch/x86 to drivers/platform/x86.
Note, the complete SFI support is going to be removed, that's why PDx86
has been chosen as a new home for it. This is the only device which needs

Add the uv_sysfs driver to construct a read-only sysfs interface at
/sys/firmware/sgi_uv/ to expose information gathered from UV BIOS. This
information includes:
* UV Hub descriptions, including physical location
* Cabling layout between hubs on the fabric
* PCI topology, including physical location of PCI cards
Together, the information provides a robust physical description of a UV
system, useful for correlating to performance data or performing remote
support.

AMD Power Management Controller driver a.k.a. amd-pmc driver is the
controller which is meant for the final S2Idle transaction that goes to
the PMFW running on the AMD SMU (System Management Unit) responsible for
tuning of the VDD.
Once all the monitored list or the idle constraints are met, this driver
would go and set the OS_HINT (meaning all the devices have reached to
their lowest state possible) via the SMU mailboxes.
This driver would also provide some debug capabilities via debugfs.

Add support for the Intel Platform Monitoring Technology crashlog
interface. This interface provides a few sysfs values to allow for
controlling the crashlog telemetry interface as well as a character
driver to allow for mapping the crashlog memory region so that it can be
accessed after a crashlog has been recorded.
This driver is meant to only support the server version of the crashlog
which is identified as crash_type 1 with a version of zero. Currently no
other types are supported.

PMT Telemetry is a capability of the Intel Platform Monitoring Technology.
The Telemetry capability provides access to device telemetry metrics that
provide hardware performance data to users from read-only register spaces.
With this driver present the intel_pmt directory can be populated with
telem<x> devices. These devices will contain the standard intel_pmt sysfs
data and a "telem" binary sysfs attribute which can be used to access the
telemetry data.
Also create a PCI device id list for early telemetry hardware that require
workarounds for known issues.

Intel Platform Monitoring Technology is meant to provide a common way to
access telemetry and system metrics.
Register mappings are not provided by the driver. Instead, a GUID is read
from a header for each endpoint. The GUID identifies the device and is to
be used with an XML, provided by the vendor, to discover the available set
of metrics and their register mapping. This allows firmware updates to
modify the register space without needing to update the driver every time
with new mappings. Firmware writes a new GUID in this case to specify the
new mapping. Software tools with access to the associated XML file can
then interpret the changes.
The module manages access to all Intel PMT endpoints on a system,
independent of the device exporting them. It creates an intel_pmt class
to manage the devices. For each telemetry endpoint, sysfs files provide
GUID and size information as well as a pointer to the parent device the
telemetry came from. Software may discover the association between
endpoints and devices by iterating through the list in sysfs, or by looking
for the existence of the class folder under the device of interest. A
binary sysfs attribute of the same name allows software to then read or map
the telemetry space for direct access.

Many Bay Trail and Cherry Trail devices come with a camera attached to
Intel's Image Signal Processor. Linux currently does not have a driver for
these, so they do not work as a camera.
Some of these camera's have a status LED which is controlled through a GPIO
in some cases, e.g. on the Asus T100TA and Asus T200TA, there is a firmware
issue where the LED gets turned on at boot.
This commit adds a Linux LED driver for the camera LED on these devices.
This driver will turn the LED off at boot and also allows controlling the
LED (so the user can repurpose it) through the sysfs LED interface.
Which GPIO is attached to the LED is usually not described in the ACPI
tables, so this driver contains per-system info about the GPIO inside the
driver. This means that this driver only works on systems the driver knows
about.

Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:

userspace-api books (a longstanding request from Jon);
- The media Kconfig was reorganized, in order to make easier to select
drivers and their dependencies;
- The testing drivers now has a separate directory;
- added a new driver for Rockchip Video Decoder IP;
- The atomisp staging driver was resurrected. It is meant to work with
4 generations of cameras on Atom-based laptops, tablets and cell

making it in good shape.
- Added some V4L2 core ancillary routines to help with h264 codecs;
- Added an ov2740 image sensor driver;
- The si2157 gained support for Analog TV, which, in turn, added
support for some cx231xx and cx23885 boards to also support analog
standards;
- Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and
V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera

Slim Bootloader(SBL) is a small open-source boot firmware,
designed for running on certain Intel platforms. SBL can be
thought-of as fulfilling the role of a minimal BIOS
implementation, i.e initializing the hardware and booting
Operating System.
Since SBL is not UEFI compliant, firmware update cannot be triggered
using standard UEFI runtime services. Further considering performance
impact, SBL doesn't look for a firmware update image on every reset
and does so only when firmware update signal is asserted.
SBL exposes an ACPI-WMI device which comes up in sysfs as
/sys/bus/wmi/44FADEB1xxx and this driver adds a
"firmware_update_request" device attribute. This attribute normally
has a value of 0 and userspace can signal SBL to update firmware,
on next reboot, by writing a value of 1 like:
echo 1 > /sys/bus/wmi/devices/44FADEB1xxx/firmware_update_request
This driver only implements a signaling mechanism, the actual firmware
update process and various details like firmware update image format,
firmware image location etc are defined by SBL and are not in the
scope of this driver.

Intel Elkhart Lake exposes SCU/PMC as an ACPI device that only supports
IPC functionality so add a platform driver supporting it. Interrupt is
optional so we let intel_scu_ipc_probe() to decide based on the passed
platform data whether it uses interrupt or polling.

This driver only creates a bunch of platform devices sharing resources
belonging to the PMC device. This is pretty much what MFD subsystem is
for so move the driver there, renaming it to intel_pmc_bxt.c which
should be more clear what it is.
MFD subsystem provides nice helper APIs for subdevice creation so
convert the driver to use those. Unfortunately the ACPI device includes
separate resources for most of the subdevices so we cannot simply call
mfd_add_devices() to create all of them but instead we need to call it
separately for each device.
The new MFD driver continues to expose two sysfs attributes that allow
userspace to send IPC commands to the PMC/SCU to avoid breaking any
existing applications that may use these. Generally this is bad idea so
document this in the ABI documentation.

The SCU IPC functionality is usable outside of Intel MID devices. For
example modern Intel CPUs include the same thing but now it is called
PMC (Power Management Controller) instead of SCU. To make the IPC
available for those split the driver into core part (intel_scu_ipc.c)
and the SCU PCI driver part (intel_scu_pcidrv.c) which then calls the
former before it goes and creates rest of the SCU devices. The SCU IPC
will also register a new class that gets assigned to the device that is
created under the parent PCI device.
We also split the Kconfig symbols so that INTEL_SCU_IPC enables the SCU
IPC library and INTEL_SCU_PCI the SCU driver and convert the users
accordingly. While there remove default y from the INTEL_SCU_PCI symbol
as it is already selected by X86_INTEL_MID.

I'm resubmitting this patch with review feedback addressed:
https://patchwork.kernel.org/patch/10584079/
The patch was previously not resubmitted because it required a change
that was reverted in the ACPICA. That has since been corrected:
9159c09a2a
We've been using this patch for a while and user reports confirm that it
works:
https://github.com/linux-surface/linux-surface
Previous description follows.
>8------------------------------------------------------8<
The MSHW0011 device is a chip that replaces the battery firmware
by using ACPI operation regions on the Surface 3.
It is unclear whether or not the chip will be reused somewhere else
(under Windows, the chip is called "Surface Platform Power Driver"
and the driver is provided by Microsoft).
The values have been obtained by reverse engineering, and are subject to
errors. Looks like it works on overall pretty well.
I couldn't manage to get the IRQ correctly triggered, so I am using a
good old polling thread to check for changes. This is something
to be fixed in a later version.

Some server users set limits on the uncore frequency using MSR 620H, while
running latency sensitive workloads. Here uncore frequency controls
RING/LLC(last-level cache) clocks.
But MSR control is not always possible from the user space, so this driver
provides a sysfs interface to set max and min frequency limits. This MSR
620H is a die scoped in multi-die system or package scoped in non multi-die
systems.
When this driver is loaded, a new directory is created under
/sys/devices/system/cpu.
For example on a two package Skylake server:
$cd /sys/devices/system/cpu/intel_uncore_frequency
$ls
package_00_die_00 package_01_die_00
$ls package_00_die_00
max_freq_khz min_freq_khz initial_max_freq_khz
initial_min_freq_khz
$grep . *

min_freq_khz:1200000
initial_max_freq_khz:2400000
initial_min_freq_khz:1200000
Here, initial_max_freq_khz and initial_min_freq_khz are read only
attributes to show power up or initial values of max and min frequencies
respectively. Other attributes are read-write, so that users can modify.

Existing intel_cht_int33fe ACPI pseudo-device driver assumes that
hardware has Type-C connector and register related devices described as
I2C connections in the _CRS resource.
There is at least one hardware (Lenovo Yoga Book YB1-91L/F) with Micro-B
USB connector exists. It has INT33FE device in the DSDT table but
there are only two I2C connection described: PMIC and BQ27452 battery
fuel gauge.
Splitting existing INT33FE driver allow to maintain code for USB Micro-B
(or AB) connector variant separately and make it simpler.
Split driver to intel_cht_int33fe_common.c and
intel_cht_int33fe_{microb,typec}.c. Compile all this sources to one .ko
module to make user experience easier.

We have added polled mode to the normal input devices with the intent of
retiring input_polled_dev. This converts peaq-wmi driver to use the
polling mode of standard input devices and removes dependency on
INPUT_POLLDEV.
Because the new polling coded does not allow peeking inside the poller
structure to get the poll interval, we change the "debounce" process to
operate on the time basis, instead of counting events.
We also fix error handling during initialization, as previously we leaked
input device structure when we failed to register it.

Move from WMI driver to platform driver. This move is necessary since
the driver is no longer a hotkeys driver only. Platform driver makes it
easier for users to access sysfs attributes under (i.e.

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.

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.

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
issues.

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.

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.

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.

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.

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

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

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.

If DELL_WMI "select"s DELL_SMBIOS, the DELL_SMBIOS dependencies are
ignored and it is still possible to end up with unmet direct
dependencies.
Change the select to a depends on.

Right now it's possible to set dell laptop to compile in but this
causes dell-smbios to compile in which breaks if dcdbas is a module.
Dell laptop shouldn't select dell-smbios anymore, but depend on it.

Dell SMBIOS driver fixed against memory leaks.
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:

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.

Similarly to DCDBAS for DELL_SMBIOS_SMM, if DELL_SMBIOS_WMI is enabled,
DELL_SMBIOS becomes dependent on ACPI_WMI. Update the depends lines to
prevent a configuration where DELL_SMBIOS=y and either backend
dependency =m. Update the comment accordingly.

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).

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.
