156ec4731c platform/x86: amd-pmc: Add AMD platform support for S2Idle
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.

3cd420b2eb platform/x86: thinkpad_acpi: Add BAT1 is primary battery quirk for Thinkpad Yoga 11e 4th gen
The Thinkpad Yoga 11e 4th gen with the N3450 / Celeron CPU only has
one battery which is named BAT1 instead of the expected BAT0, add a
quirk for this. This fixes not being able to set the charging tresholds
on this model; and this alsoe fixes the following errors in dmesg:

ACPI: \_SB_.PCI0.LPCB.EC__.HKEY: BCTG evaluated but flagged as error
thinkpad_acpi: Error probing battery 2
battery: extension failed to load: ThinkPad Battery Extension
battery: extension unregistered: ThinkPad Battery Extension

Note that the added quirk is for the "R0K" BIOS versions which are
used on the Thinkpad Yoga 11e 4th gen's with a Celeron CPU, there
is a separate "R0L" BIOS for the i3/i5 based versions. This may also
need the same quirk, but if that really is necessary is unknown.

685489a32c platform/x86: thinkpad_acpi: Do not report SW_TABLET_MODE on Yoga 11e
The Yoga 11e series has 2 accelerometers described by a BOSC0200 ACPI node.
This setup relies on a Windows service which reads both accelerometers and
then calculates the angle between the 2 halves to determine laptop / tent /
tablet mode and then reports the calculated mode back to the EC by calling
special ACPI methods on the BOSC0200 node.

The bmc150 iio driver does not support this (it involves double
calculations requiring sqrt and arccos so this really needs to be done
in userspace), as a result of this on the Yoga 11e the thinkpad_acpi
code always reports SW_TABLET_MODE=0, starting with GNOME 3.38 reporting
SW_TABLET_MODE=0 causes GNOME to:

1. Not show the onscreen keyboard when a text-input field is focussed
   with the touchscreen.
2. Disable accelerometer based auto display-rotation.

This makes sense when in laptop-mode but not when in tablet-mode. But
since for the Yoga 11e the thinkpad_acpi code always reports
SW_TABLET_MODE=0, GNOME does not know when the device is in tablet-mode.

Stop reporting the broken (always 0) SW_TABLET_MODE on Yoga 11e models
to fix this.

Note there are plans for userspace to support 360 degree hinges style
2-in-1s with 2 accelerometers and figure out the mode by itself, see:

5ef9998c96 platform/x86: Intel PMT Crashlog capability driver
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.

e2729113ce platform/x86: Intel PMT class driver
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.

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

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

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

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

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

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

ea856ec266 platform/x86: asus-wmi: Add support for SW_TABLET_MODE on UX360
The UX360CA has a WMI device id 0x00060062, which reports whether the
lid is flipped in tablet mode (1) or in normal laptop mode (0).

Add a quirk (quirk_asus_use_lid_flip_devid) for devices on which this
WMI device should be used to figure out the SW_TABLET_MODE state, as
opposed to the quirk_asus_use_kbd_dock_devid.

Additionally, the device needs to be queried on resume and restore
because the firmware does not generate an event if the laptop is put to
sleep while in tablet mode, flipped to normal mode, and later awoken.

It is assumed other UX360* models have the same WMI device. As such, the
quirk is applied to devices with DMI_MATCH(DMI_PRODUCT_NAME, "UX360").
More devices with this feature need to be tested and added accordingly.

The reason for using an allowlist via the quirk mechanism is that the new
WMI device (0x00060062) is also present on some models which do not have
a 360 degree hinge (at least FX503VD and GL503VD from Hans' DSTS
collection) and therefore its presence cannot be relied on.

When unloading wmi driver module, device #2 will be first unregistered.
But device_destroy() using MKDEV(0, 0) will locate PNP0C14:00 first

c071afcea6 platform/x86: mlx-platform: Remove PSU EEPROM configuration
Remove PSU EEPROM configuration for systems class equipped with
Mellanox chip Spectrume-2. Till now all the systems from this class
used few types of power units, all equipped with EEPROM device with
address space two bytes. Thus, all these devices have been handled by
EEPROM driver "24c32".
There is a new requirement is to support power unit replacement by "off
the shelf" device, matching electrical required parameters. Such device
could be equipped with different EEPROM type, which could be one byte
address space addressing or even could be not equipped with EEPROM.
In such case "24c32" will not work.

46461f8709 platform/x86: intel_pmc_core: fix: Replace dev_dbg macro with dev_info()
dev_dbg macro is used to dump the debug registers in resume from an S0ix
failure. However, when CONFIG_DYNAMIC_DEBUG is not set, the user may not be
able to find the debug dump on an S0ix failure which defeats the purpose.
The output of these messages is already controlled by a module parameter,
warn_on_s0ix_failures, making it a 2 step process to enable anyway when
CONFIG_DYNAMIC_DEBUG is set.

Hence, replace dev_dbg with dev_info, allowing the control of the messages
solely through the module parameter which is N by default.

Fixes commit 913f984a83 ("platform/x86: intel_pmc_core: Add an
additional parameter to pmc_core_lpm_display()")

HP Spectre notebooks (and probably other model as well)
support up to 4 thermal policy:
 - HP Recommended
 - Performance
 - Cool
 - Quiet

at least on HP Spectre x360 Convertible 15-df0xxx the firmware sets the
thermal policy to default but hardcode the odvp0 variable to 1, this causes
thermald to choose the wrong DPTF profile witch result in low performance
when notebook is on AC, calling thermal policy write command allow firmware
to correctly set the odvp0 variable.

 "One final pdx86 fix for Tablet Mode reporting regressions (which make

  These regressions were caused by the asus-nb-wmi and the intel-vbtn

  to report it on more models.

  Due to a miscommunication between Andy and me, Andy's earlier pull-req

Hans de Goede
1797d588af platform/x86: asus-wmi: Fix SW_TABLET_MODE always reporting 1 on many different models
Commit b0dbd97de1 ("platform/x86: asus-wmi: Add support for
SW_TABLET_MODE") added support for reporting SW_TABLET_MODE using the
Asus 0x00120063 WMI-device-id to see if various transformer models were
docked into their keyboard-dock (SW_TABLET_MODE=0) or if they were
being used as a tablet.

The new SW_TABLET_MODE support (naively?) assumed that non Transformer
devices would either not support the 0x00120063 WMI-device-id at all,
or would NOT set ASUS_WMI_DSTS_PRESENCE_BIT in their reply when querying
the device-id.

Unfortunately this is not true and we have received many bug reports about
this change causing the asus-wmi driver to always report SW_TABLET_MODE=1
on non Transformer devices. This causes libinput to think that these are
360 degree hinges style 2-in-1s folded into tablet-mode. Making libinput
suppress keyboard and touchpad events from the builtin keyboard and
touchpad. So effectively this causes the keyboard and touchpad to not work
on many non Transformer Asus models.

This commit fixes this by using the existing DMI based quirk mechanism in
asus-nb-wmi.c to allow using the 0x00120063 device-id for reporting
SW_TABLET_MODE on Transformer models and ignoring it on all other models.

8169bd3e6e platform/x86: intel-vbtn: Switch to an allow-list for SW_TABLET_MODE reporting
2 recent commits:
cfae58ed68 ("platform/x86: intel-vbtn: Only blacklist SW_TABLET_MODE
on the 9 / "Laptop" chasis-type")
1fac39fd03 ("platform/x86: intel-vbtn: Also handle tablet-mode switch on
"Detachable" and "Portable" chassis-types")

Enabled reporting of SW_TABLET_MODE on more devices since the vbtn ACPI
interface is used by the firmware on some of those devices to report this.

Testing has shown that unconditionally enabling SW_TABLET_MODE reporting
on all devices with a chassis type of 8 ("Portable") or 10 ("Notebook")
which support the VGBS method is a very bad idea.

Many of these devices are normal laptops (non 2-in-1) models with a VGBS
which always returns 0, which we translate to SW_TABLET_MODE=1. This in
turn causes userspace (libinput) to suppress events from the builtin
keyboard and touchpad, making the laptop essentially unusable.

Since the problem of wrongly reporting SW_TABLET_MODE=1 in combination
with libinput, leads to a non-usable system. Where as OTOH many people will
not even notice when SW_TABLET_MODE is not being reported, this commit
changes intel_vbtn_has_switches() to use a DMI based allow-list.

The new DMI based allow-list matches on the 31 ("Convertible") and
32 ("Detachable") chassis-types, as these clearly are 2-in-1s and
so far if they support the intel-vbtn ACPI interface they all have
properly working SW_TABLET_MODE reporting.

Besides these 2 generic matches, it also contains model specific matches
for 2-in-1 models which use a different chassis-type and which are known
to have properly working SW_TABLET_MODE reporting.

This has been tested on the following 2-in-1 devices:

Dell Venue 11 Pro 7130 vPro
HP Pavilion X2 10-p002nd
HP Stream x360 Convertible PC 11
Medion E1239T

938835aa90 platform/x86: intel_pmc_core: do not create a static struct device
A struct device is a dynamic structure, with reference counting.
"Tricking" the kernel to make a dynamic structure static, by working
around the driver core release detection logic, is not nice.

Because of this, this code has been used as an example for others on
"how to do things", which is just about the worst thing possible to have
happen.

Fix this all up by making the platform device dynamic and providing a
real release function.

d823346876 platform/x86: intel-vbtn: Fix SW_TABLET_MODE always reporting 1 on the HP Pavilion 11 x360
Commit cfae58ed68 ("platform/x86: intel-vbtn: Only blacklist
SW_TABLET_MODE on the 9 / "Laptop" chasis-type") restored SW_TABLET_MODE
reporting on the HP stream x360 11 series on which it was previously broken
by commit de9647efea ("platform/x86: intel-vbtn: Only activate tablet
mode switch on 2-in-1's").

It turns out that enabling SW_TABLET_MODE reporting on devices with a
chassis-type of 10 ("Notebook") causes SW_TABLET_MODE to always report 1
at boot on the HP Pavilion 11 x360, which causes libinput to disable the
kbd and touchpad.

The HP Pavilion 11 x360's ACPI VGBS method sets bit 4 instead of bit 6 when
NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT collection
shows only one other model, the Medion E1239T ever setting bit 4 and it
always sets this together with bit 6.

So lets treat bit 4 as a second bit which when set indicates the device not
being in tablet-mode, as we already do for bit 6.

While at it also prefix all VGBS constant defines with "VGBS_".

8a333dab28 platform/x86: asus-nb-wmi: Revert "Do not load on Asus T100TA and T200TA"
The WMI INIT method on for some reason turns on the camera LED on these
2-in-1s, without the WMI interface allowing further control over the LED.

To fix this commit b5f7311d3a ("platform/x86: asus-nb-wmi: Do not load
on Asus T100TA and T200TA") added a blacklist with these 2 models on it
since the WMI driver did not add any extra functionality to these models.

Recently I've been working on making more 2-in-1 models report their
tablet-mode (SW_TABLET_MODE) to userspace; and I've found that these 2
Asus models report this through WMI. This commit reverts the adding
of the blacklist, so that the Asus WMI driver can be used on these
models to report their tablet-mode. I have another patch fixing the LED
issue in a different manner.

Note this is the second time the we revert the adding of the
asus_nb_wmi_blacklist. It was reverted before in commit:

aab9e7896e ("platform/x86: asus-nb-wmi: Revert "Do not load on Asus
T100TA and T200TA")"

But some how (accidentally re-applying of the patch?) it got re-added
again in commit 3bd12da7f5 ("platform/x86: asus-nb-wmi: Do not load
on Asus T100TA and T200TA"), so now we need to revert it again.

Commit 696c6523ec ("platform/x86: thinkpad_acpi: add mapping for new
hotkeys") added support for a bunch of new hotkeys, but the
clipping/snipping tool hotkey got ignored because there was no good
key-code to map it to.

Recently a new KEY_SELECTIVE_SCREENSHOT keycode was added by commit
3b059da983 ("Input: allocate keycode for "Selective Screenshot" key")
quoting from the commit message:

"New Chrome OS keyboards have a "snip" key that is basically a selective
screenshot (allows a user to select an area of screen to be copied).
Allocate a keycode for it."

Support for this "snip" key seems like it is also a good match for the
clipping/snipping tool hotkey, so map this hotkey to the new
KEY_SELECTIVE_SCREENSHOT key-code.

7ed7748d2c platform/x86: thinkpad_acpi: Add support for new hotkeys found on X1C8 / T14
New Lenovo Thinkpad models, e.g. the X1 Carbon 8th gen and the new T14 gen1
models have 3 new symbols / shortcuts on their F9-F11 keys (and the
thinkpad_acpi driver receives 3 new hkey events for these):

F9:  Has a symbol resembling a rectangular speech balloon, the manual says
     the hotkey functions shows or hides the notification center
F10: Has a symbol of a telephone horn which has been picked up from the
     receiver, the manual says: "Answer incoming calls"
F11: Has a symbol of a telephone horn which is resting on the receiver,
     the manual says: "Decline incoming calls"

And these Thinkpad models also send a new 0x1316 hkey events when the
Fn + right Shift key-combo is pressed.

This commit adds support for these 4 new hkey events.

f6b35db072 First set of new device support, cleanups and features for IIO in the 5.9 cycle
Some new devices, but particularly good this time is the core rework coming
 from Alexandru. Some of this has been in Analog's tree a long time, but other
 parts are motivated by closing down common mistakes in new drivers.
 
 Changes since first try at this pull request:
 * Add missed patch to actually remove iio_priv_to_dev and as a result
   also drop a few ingenic patches that need to be updated to take this
   into account.
 * Fix an ordering issue int he pollfunc attach in the core rework.
 
 New device support
 * qcom pmic7 adc
   - New driver using common qcom-vadc library. Some associated cleanups and
     refactors.
 * invensense icm42600
   - New driver supporting icm42600, icm42602, icm42605 and icm42622 via i2c
     or spi.  These are all 6 axis IMUs with gyro and accelerometers.
     Driver supports buffered modes using the hardware fifo and interpolation
     for accurate timestamps.
 * sensirion scd30
   - New driver for this carbon dioxide sensor including i2c and serial
     interfaces + bindings.
 
 Features
 * ak8975
   - Add reset gpio support.
 * bma400
   - Support SPI.
 * bmc150
   - Document and add support for bmc156b and bmm150b, tidy up _magn endings.
 * bmi160
   - Regulator and mount matrix support.
 * mxc4005
   - Add ID for mxc6655
 * rockchip-saradc
   - Triggered buffer support.
 
 DT bindings
 * qcom spmi-vadc converted to yaml + pmic7 bindings
 * ak8975 tidy up and convert to yaml + add reset-gpio binding
 * ingenic-adc -convert to yaml.
 
 Core rework all carried through by Alexandru Ardelean.
 * Assign parent device in the core rather than every driver. A few devices
   need to provide specific non standard parents, so there is support for
   overriding.
 * Start to take parts of struct iio_dev opaque to the drivers.
   This will be a long term job, but should reduce the number of drivers
   we get that use parts that are currently only 'internal' by documentation.
 * Move attach and detach of pollfunc to the core.  Every triggered buffer
   using driver had to do the same thing, so lets do it in the core.  The
   hard part here was getting all the drivers into canonical form so there
   would be no functional changes in this final patch.  That's taken quite
   a lot of work over last couple of cycles!
 
 Cleanups and minor fixes.
 * docs
   - Improve IIO_CONCENTRATION channel type description in ABI docs.
   - Drop doubled word cases.
   - Http to Https conversion.
 * core
   - Make iio_device_get_drvdata take a const struct iio_dev * avoiding some
     nasty casts.
 * ADCs
   - Drop lots of users of of_match_ptr macro, includes of mod_devicetable.h
     and CONFIG_OF protections.  These prevent use of ACPI PRP0001 with these
     drivers and get coppied into lots of new drivers.
 * ad5380
   - Constify iio_chan_spec_ext_info
 * ad5592r
   - Constify iio_chan_spec_ext_info
   - Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)

3f649ab728 treewide: Remove uninitialized_var() usage
Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.

In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:

git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
	xargs perl -pi -e \
		's/\buninitialized_var\(([^\)]+)\)/\1/g;
		 s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'

drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.

No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

78d15eea08 platform/x86: acerhdf: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

f560cd5021 platform/x86: pcengines-apuv2: revert wiring up simswitch GPIO as LED
This reverts commit 5037d4ddda.

Explanation why this does not work:
This change connects the simswap to the LED subsystem of the kernel.
From my point of view, it's nonsense. If we do it this way, then this
can be switched relatively easily via the LED subsystem (trigger:
none/default-on) and that is dangerous! If this is used, it would be
unfavorable, since there is also another trigger (trigger:
heartbeat/netdev).

Therefore, this simswap GPIO should remain in the GPIO
subsystem and be switched via it and not be connected to the LED
subsystem. To avoid the problems mentioned above. The LED subsystem is
not made for this and it is not a good compromise, but rather dangerous.

4b2d688fed platform/x86: Add new intel_atomisp2_led driver
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.

7f4957be0d thermal: Use mode helpers in drivers
Use thermal_zone_device_{en|dis}able() and thermal_zone_device_is_enabled().

Consequently, all set_mode() implementations in drivers:

- can stop modifying tzd's "mode" member,
- shall stop taking tzd's lock, as it is taken in the helpers
- shall stop calling thermal_zone_device_update() as it is called in the
helpers
- can assume they are called when the mode truly changes, so checks to
verify that can be dropped

Not providing set_mode() by a driver no longer prevents the core from
being able to set tzd's mode, so the relevant check in mode_store() is
removed.

Other comments:

- acpi/thermal.c: tz->thermal_zone->mode will be updated only after we
return from set_mode(), so use function parameter in thermal_set_mode()
instead, no need to call acpi_thermal_check() in set_mode()
- thermal/imx_thermal.c: regmap writes and mode assignment are done in
thermal_zone_device_{en|dis}able() and set_mode() callback
- thermal/intel/intel_quark_dts_thermal.c: soc_dts_{en|dis}able() are a
part of set_mode() callback, so they don't need to modify tzd->mode, and
don't need to fall back to the opposite mode if unsuccessful, as the return
value will be propagated to thermal_zone_device_{en|dis}able() and
ultimately tzd's member will not be changed in thermal_zone_device_set_mode().
- thermal/of-thermal.c: no need to set zone->mode to DISABLED in
of_parse_thermal_zones() as a tzd is kzalloc'ed so mode is DISABLED anyway

78289b4a58 iio: core: pass parent device as parameter during allocation
The change passes the parent device to the iio_device_alloc() call. This
also updates the devm_iio_device_alloc() call to consider the device object
as the parent device by default.

Having it passed like this, should ensure that any IIO device object
already has a device object as parent, allowing for neater control, like
passing the 'indio_dev' object for other stuff [like buffers/triggers/etc],
and potentially creating iiom_xxx(indio_dev) functions.

With this patch, only the 'drivers/platform/x86/toshiba_acpi.c' needs an
update to pass the parent object as a parameter.

In the next patch all devm_iio_device_alloc() calls will be handled.

Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over

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:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Pull media updates from Mauro Carvalho Chehab:

 - Media documentation is now split into admin-guide, driver-api and
   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
   phones. So, it seems worth investing time to cleanup this driver and
   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
   is located at the device;

 - VIDIOC_ENUM_FMT was extended to support MC-centric devices;

 - Lots of drivers improvements and cleanups.

7b91f1565f platform/x86: asus_wmi: Reserve more space for struct bias_args
On the ASUS laptop UX325JA/UX425JA, most of the media keys are not
working due to the ASUS WMI driver fails to be loaded. The ACPI error
as follows leads to the failure of asus_wmi_evaluate_method.
  ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [IIA3] at bit offset/length 96/32 exceeds size of target Buffer (96 bits) (20200326/dsopcode-203)
  No Local Variables are initialized for Method [WMNB]
  ACPI Error: Aborting method \_SB.ATKD.WMNB due to previous error (AE_AML_BUFFER_LIMIT) (20200326/psparse-531)

The DSDT for the WMNB part shows that 5 DWORD required for local
variables and the 3rd variable IIA3 hit the buffer limit.

Method (WMNB, 3, Serialized)
{ ..
    CreateDWordField (Arg2, Zero, IIA0)
    CreateDWordField (Arg2, 0x04, IIA1)
    CreateDWordField (Arg2, 0x08, IIA2)
    CreateDWordField (Arg2, 0x0C, IIA3)
    CreateDWordField (Arg2, 0x10, IIA4)
    Local0 = (Arg1 & 0xFFFFFFFF)
    If ((Local0 == 0x54494E49))
  ..
}

The limitation is determined by the input acpi_buffer size passed
to the wmi_evaluate_method. Since the struct bios_args is the data
structure used as input buffer by default for all ASUS WMI calls,
the size needs to be expanded to fix the problem.

cfae58ed68 platform/x86: intel-vbtn: Only blacklist SW_TABLET_MODE on the 9 / "Laptop" chasis-type
The HP Stream x360 11-p000nd no longer report SW_TABLET_MODE state / events
with recent kernels. This model reports a chassis-type of 10 / "Notebook"
which is not on the recently introduced chassis-type whitelist

Commit de9647efea ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a chassis-type whitelist and only listed 31 /
"Convertible" as being capable of generating valid SW_TABLET_MOD events.

Commit 1fac39fd03 ("platform/x86: intel-vbtn: Also handle tablet-mode
switch on "Detachable" and "Portable" chassis-types") extended the
whitelist with chassis-types 8 / "Portable" and 32 / "Detachable".

And now we need to exten the whitelist again with 10 / "Notebook"...

The issue original fixed by the whitelist is really a ACPI DSDT bug on
the Dell XPS 9360 where it has a VGBS which reports it is in tablet mode
even though it is not a 2-in-1 at all, but a regular laptop.

So since this is a workaround for a DSDT issue on that specific model,
instead of extending the whitelist over and over again, lets switch to
a blacklist and only blacklist the chassis-type of the model for which
the chassis-type check was added.

Note this also fixes the current version of the code no longer checking
if dmi_get_system_info(DMI_CHASSIS_TYPE) returns NULL.

After that, you wouldn't see the platform::micmute in /sys/class/leds/,

dd950f16b1 platform/x86: intel-vbtn: Detect switch position before registering the input-device
Setting the initial state of input-device switches must be done before
registering the input-device.

Otherwise the initial state will get send out as an event as soon
as input_sync() gets called.

E.g. when undocking a tablet using intel-vbtn to report SW_TABLET_MODE
and SW_DOCK before this commit we would get (evemu-record output):

E: 0.000001 0005 0005 0001	# EV_SW / SW_DOCK              1
E: 0.000001 0000 0000 0000	# ------------ SYN_REPORT (0) ---------- +0ms
E: 0.000109 0005 0005 0000	# EV_SW / SW_DOCK              0
E: 0.000109 0000 0000 0000	# ------------ SYN_REPORT (0) ---------- +0ms
E: 0.000133 0005 0001 0001	# EV_SW / SW_TABLET_MODE       1
E: 0.000133 0000 0000 0000	# ------------ SYN_REPORT (0) ---------- +0ms

The first SW_DOCK=1 report is spurious, setting the initial switch
state before registering the input-device fixes this.

10d7ff74b6 platform/x86: asus-wmi: Ignore WMI events with code 0x79
On some Asus devices, e.g. the T100TA, when the charger is connected
we not only get a WMI event with code 0x58, but immediately after that
event we also get an even with code 0x79.

This is likely related to these devices having an Asus WMI device with a
device-id of 0x00120066, which seems to provide some sort of charger-type
info. The T100TA charger over a micro-USB connector, the embedded-
controller register read when calling asus_wmi_get_devstate(0x00120066)
returns different values when connected to a USB port (max 500mA charging)
vs when connected to a 2A capable wall-charger. But the AML code reading
this mangles the return value so that we can no longer tell the difference.
So for now the meaning of the value return when getting the status of
device-id 0x00120066 is unclear.

This commit adds a key-mapping of code 0x79 to KE_IGNORE, silencing the
kernel logging the following message every time the charger is plugged-in:

[   79.639548] asus_wmi: Unknown key 79 pressed

aab9e7896e platform/x86: asus-nb-wmi: Revert "Do not load on Asus T100TA and T200TA"
The WMI INIT method on for some reason turns on the camera LED on these
2-in-1s, without the WMI interface allowing further control over the LED.

To fix this commit b5f7311d3a ("platform/x86: asus-nb-wmi: Do not load
on Asus T100TA and T200TA") added a blacklist with these 2 models on it
since the WMI driver did not add any extra functionality to these models.

Recently I've been working on making more 2-in-1 models report their
tablet-mode (SW_TABLET_MODE) to userspace; and I've found that these 2
Asus models report this through WMI. This commit reverts the adding
of the blacklist, so that the Asus WMI driver can be used on these
models to report their tablet-mode.

Note, not calling INIT is also not an option, because then we will not
receive events when the tablet-mode changes. So the LED issue will need
to be fixed somewhere else entirely.

1fac39fd03 platform/x86: intel-vbtn: Also handle tablet-mode switch on "Detachable" and "Portable" chassis-types
Commit de9647efea ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a DMI chassis-type check to avoid accidentally
reporting SW_TABLET_MODE = 1 to userspace on laptops.

Some devices with a detachable keyboard and using the intel-vbnt (INT33D6)
interface to report if they are in tablet mode (keyboard detached) or not,
report 32 / "Detachable" as chassis-type, e.g. the HP Pavilion X2 series.

Other devices with a detachable keyboard and using the intel-vbnt (INT33D6)
interface to report SW_TABLET_MODE, report 8 / "Portable" as chassis-type.
The Dell Venue 11 Pro 7130 is an example of this.

Extend the DMI chassis-type check to also accept Portables and Detachables
so that the intel-vbtn driver will report SW_TABLET_MODE on these devices.

Note the chassis-type check was originally added to avoid a false-positive
tablet-mode report on the Dell XPS 9360 laptop. To the best of my knowledge
that laptop is using a chassis-type of 9 / "Laptop", so after this commit
we still ignore the tablet-switch for that chassis-type.

Commit de9647efea ("platform/x86: intel-vbtn: Only activate tablet mode

userspace thought the device was in tablet-mode.

But if we are not getting the initial status of the switch because the
device does not have a tablet mode, then we really should not advertise
the presence of a tablet-mode switch to userspace at all, as userspace may
use the mere presence of this switch for certain heuristics.

2d30fcdd43 platform/x86: Add Slim Bootloader firmware update signaling driver
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.

Besides not adding any extra functionality, initializing the WMI interface

the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives
GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED,

14232c6e78 platform/x86: thinkpad_acpi: Add support for dual fan control
This adds dual fan control for the following models:
P50, P51, P52, P70, P71, P72, P1 gen1, P2 gen2, X1E gen1 and X1E gen2.

Both fans are controlled together as if they were a single fan.

Tested on an X1 Extreme Gen1, an X1 Extreme Gen2, and a P50.

The patch is defensive, it adds only specific supported machines, and falls
back to the old behavior if both fans cannot be controlled.

Background:
I tested the BIOS default behavior on my X1E gen2 and both fans are always
changed together. So rather than adding controls for each fan, this controls
both fans together as the BIOS would do.

This was inspired by a discussion on dual fan support for the thinkfan tool
(see link below). All BIOS IDs are taken from there. The X1E gen2 ID is
verified on my machine.

Thanks to GitHub users voidworker and civic9 for the earlier patches and
BIOS IDs, and to users peter-stoll and sassman for testing the patch on
their machines.

25f1ca31e2 platform/x86: intel_pmc_ipc: Convert to MFD
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.

f57fa18583 platform/x86: intel_scu_ipc: Introduce new SCU IPC API
The current SCU IPC API has been operating on a single instance and
there has been no way to pin the providing module in place when the SCU
IPC is in use.

This implements a new API that takes the SCU IPC instance as first
parameter (NULL means the single instance is being used). The SCU IPC
instance can be retrieved by calling new function intel_scu_ipc_dev_get()
that take care of pinning the providing module in place as long as
intel_scu_ipc_dev_put() is not called.

The old API is updated to call the new API and is is left there in the
legacy API header to support the existing users that cannot be converted
easily.

Subsequent patches will convert most of the users over to the new API.

54b34aa0a7 platform/x86: intel_scu_ipc: Split out SCU IPC functionality from the SCU driver
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.

b5f7311d3a platform/x86: asus-nb-wmi: Do not load on Asus T100TA and T200TA
asus-nb-wmi does not add any extra functionality on these Asus
Transformer books. They have detachable keyboards, so the hotkeys are
send through a HID device (and handled by the hid-asus driver) and also
the rfkill functionality is not used on these devices.

Besides not adding any extra functionality, initializing the WMI interface
on these devices actually has a negative side-effect. For some reason
the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives
GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED,
high and there is no (WMI or other) interface to drive this low again
causing the LED to be permanently on, even during suspend.

This commit adds a blacklist of DMI system_ids on which not to load the
asus-nb-wmi and adds these Transformer books to this list. This fixes
the webcam LED being permanently on under Linux.

767191db82 platform/x86: intel_int0002_vgpio: Use acpi_register_wakeup_handler()
The Power Management Events (PMEs) the INT0002 driver listens for get
signalled by the Power Management Controller (PMC) using the same IRQ
as used for the ACPI SCI.

Since commit fdde0ff859 ("ACPI: PM: s2idle: Prevent spurious SCIs from
waking up the system") the SCI triggering, without there being a wakeup
cause recognized by the ACPI sleep code, will no longer wakeup the system.

This breaks PMEs / wakeups signalled to the INT0002 driver, the system
never leaves the s2idle_loop() now.

Use acpi_register_wakeup_handler() to register a function which checks
the GPE0a_STS register for a PME and trigger a wakeup when a PME has
been signalled.

 "The main changes in this cycle were:

   - Continued user-access cleanups in the futex code.

   - percpu-rwsem rewrite that uses its own waitqueue and atomic_t

     weaknesses, but the primary motivation was complications on the -rt
     kernel.

   - Introduce raw lock nesting detection on lockdep
     (CONFIG_PROVE_RAW_LOCK_NESTING=y), document the raw_lock vs. normal
     lock differences. This too originates from -rt.

   - Reuse lockdep zapped chain_hlocks entries, to conserve RAM
     footprint on distro-ish kernels running into the "BUG:
     MAX_LOCKDEP_CHAIN_HLOCKS too low!" depletion of the lockdep
     chain-entries pool.

b1f81b496b platform/x86: surface3_power: MSHW0011 rev-eng implementation
Patch was rebased on top of for-next. Thanks for your patience!

Blaž

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.

b901c2f5b9 platform/x86: i2c-multi-instantiate: Replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

64b73cff66 platform/x86/intel-uncore-freq: Fix static checker issue and potential race condition
There is a possible race condition when:
All CPUs in a package is offlined and just before the last CPU offline,
user tries to read sysfs entry and read happens while offline callback
is about to delete the sysfs entry.

Although not reproduced but this is possible scenerio and can be
reproduced by adding a msleep() in the show_min_max_freq_khz() before
mutex_lock() and read min_freq attribute from user space. Before
msleep() finishes, force every CPUs in a package offline.

This will cause deadlock, with offline and sysfs read/write operation
because of mutex_lock. The uncore_remove_die_entry() will not release
mutex till read/write callback returns because of kobject_put() and
read/write callback waiting on mutex.

We don't have to remove the sysfs folder when the package is offline.
While there is no CPU present, we can fail the read/write calls by
returning ENXIO error. So remove the kobject_put() call in offline path.

This also address the warning from static checker, as there is no
access to "data" variable after kobject_put:
"The patch 49a474c7ba: "platform/x86: Add support for Uncore
frequency control" from Jan 13, 2020, leads to the following static
checker warning:

Add Jasper Lake to the list of the platforms that intel_pmc_core
driver supports for pmc_core device.

Just like Ice Lake, Tiger Lake and Elkhart Lake, Jasper Lake can also
reuse all the Cannon Lake PCH IPs. Also, it uses the same PCH IPs of
Tiger Lake, no additional effort is needed to enable but to simply reuse
them.

Conversion rule is:

	llseek		=> proc_lseek
	unlocked_ioctl	=> proc_ioctl

	xxx		=> proc_xxx

	delete ".owner = THIS_MODULE" line

dccad6f78c platform/x86: intel_menlow: switch to use <linux/units.h> helpers
This switches the intel_menlow driver to use deci_kelvin_to_celsius()
and celsius_to_deci_kelvin() in <linux/units.h> instead of helpers in
<linux/thermal.h>.

This is preparation for centralizing the kelvin to/from Celsius
conversion helpers in <linux/units.h>.

This also removes a trailing space, while we're at it.

f07b9fdf00 platform/x86: asus-wmi: switch to use <linux/units.h> helpers
The asus-wmi driver doesn't implement the thermal device functionality
directly, so including <linux/thermal.h> just for
DECI_KELVIN_TO_CELSIUS() is a bit odd.

This switches the asus-wmi driver to use deci_kelvin_to_millicelsius()
in <linux/units.h>.

The format string is changed from %d to %ld due to function returned
type.

  by software power off request through CPLD. by signal asserted by SOC
  through ACPI register. It introduces more reset causes, which can
  be monitored after the reboots.
- Setting and removing system VPD (EEPROM) hardware write protection.
  It allows to access VPD during production cycle and prevents VPD
  corruption on system in field.
- Voltage regulator devices configuration update status and version. It
  allows to monitor configuration update status and current active
  version for such sort of devices.
- PCIe ASIC reset disable - when set ASIC will go down upon PCIe
  root complex reset, otherwise ASIC will stay up during PCIe root
  complex reset.
- System configuration Ids to provide system static topology
  identification, like system's static I2C topology, number and type of
  FPGA devices within the system and so on.

"msn21xx".

49a474c7ba platform/x86: Add support for Uncore frequency control
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 . *
    max_freq_khz:2400000
    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.

Use our default values when wrong module-parameters are given, instead of

setting, which is "Off". The CPU's thermal throttling should protect the
system from damage, but not-loading is really not the best fallback in this
case.

This commit fixes this by re-setting module-parameter values to their
defaults if they are out of range, instead of failing the probe with
-EINVAL.

e398547818 platform/x86: intel_pmc_core: Create platform dependent bitmap structs
The current implementation of intel_pmc_core driver allows to reuse, but does
not reflect the exact number and names of IPs for a newer platform which
does not necessarily support all the IPs in the entries. The names and
number of these IPs might differ from its previous platforms. The number
of PCH IPs per platform is calculated based on PPFEAR_NUM_ENTRIES
defined, where each entry represents a bucket (8 bits). The platform can
support 'n' entries, but not necessarily all 'n * 8' IPs.

Create platform dependent bitmap structures to specify the exact number,
names of IPs while reusing the existing IPs.

The changes in this patch are preparatory to accommodate future SoCs
that might reuse the CNL/ICL PCH IPs, and to reflect the exact number of
IPs with its names.

b1cb33dae4 platform/x86: intel_pmc_core: Clean up: Remove comma after the termination line
It is common practice to place a comma after the last entry in an
initialized array to avoid the need to add one in future patches that
extend the array. But when the last element is a termination marker, the
comma could be harmful. Any new entries must be added before the
terminator (and the comma would prevent the compiler from issuing a
warning about an entry after the terminator).
