[ Upstream commit e97a34563d18606ee5db93e495382a967f999cd4 ]
Power button suspend for some Dell models was added in:
commit 821b85366284 ("platform/x86: intel-hid: Power button suspend on Dell Latitude 7275")
by checking against the power button press notification (0xCE) to report
the power button press event. The corresponding power button release
notification (0xCF) was caught and ignored to stop it from being reported
as an "unknown event" in the logs.The missing button release event is creating issues on Android-x86, as
reported on the project mailing list for a Dell Latitude 5175 model, since
the events are expected in down/up pairs.Report the power button release event to fix this issue.

[ Upstream commit 0e68eeea9894feeba2edf7ec63e4551b87f39621 ]
A previous commit "platform/x86: intel_pmc_core: Make the driver PCH
family agnostic " provided
better abstraction to this driver but has some fundamental issues.e.g. the following condition
for (index = 0; index < pmcdev->map->ppfear_buckets &&
index < PPFEAR_MAX_NUM_ENTRIES; index++, iter++)is wrong because for CNL, PPFEAR_MAX_NUM_ENTRIES is hardcoded as 5 which
is _wrong_ and even though ppfear_buckets is 8, the loop fails to read
all eight registers needed for CNL PCH i.e. PPFEAR0 and PPFEAR1. This
patch refactors the pfear show logic to correctly read PCH IP power
gating status for Cannonlake and beyond.Cc: "David E. Box"

Shift by one the registers for tachometers (7 - 12).
This fix is relevant for the same new systems MQMB7, MSN37, MSN34,
which are about to be released to the customers.
At the moment, none of them is at customers sites. The customers will
not suffer from this change.
This fix is necessary, because register used before for tachometer 7
has been than reserved for the second PWM for newer systems, which are
not supported yet in mlx-platform driver. So registers of tachometers
7-12 have been shifted by one.Fixes: 0378123c5800 ("platform/x86: mlx-platform: Add mlxreg-fan platform driver activation")

[ Upstream commit 6ad16b78a039b45294b1ad5d69c14ac57b2fe706 ]
EC_MKBP_EVENT_SENSOR_FIFO events can be triggered for a variety of
reasons, and there are very few cases in which they should be treated as
wakeup interrupts (particularly, when a certain
MOTIONSENSE_MODULE_FLAG_* is set, but this is not even supported in the
mainline cros_ec_sensor driver yet). Most of the time, they are benign
sensor readings. In any case, the top-level cros_ec device doesn't know
enough to determine that they should wake the system, and so it should
not report the event. This would be the job of the cros_ec_sensors
driver to parse.This patch adds checks to cros_ec_get_next_event() such that it doesn't
signal 'wakeup' for events of type EC_MKBP_EVENT_SENSOR_FIFO.This patch is particularly relevant on devices like Scarlet (Rockchip
RK3399 tablet, known as Acer Chromebook Tab 10), where the EC firmware
reports sensor events much more frequently. This was causing
/sys/power/wakeup_count to increase very frequently, often needlessly
interrupting our ability to suspend the system.Signed-off-by: Brian Norris

According to Asus firmware engineers, the meaning of these codes is only
to notify the OS that the screen brightness has been turned on/off by
the EC. This does not match the meaning of KEY_DISPLAYTOGGLE /

brightness.Signed-off-by: João Paulo Rechi Vita

When the OS registers to handle events from the display off hotkey the
EC will send a notification with 0x35 for every key press, independent
of the backlight state.The behavior of this key on Windows, with the ATKACPI driver from Asus
installed, is turning off the backlight of all connected displays with a
fading effect, and any cursor input or key press turning the backlight
back on. The key press or cursor input that wakes up the display is also
passed through to the application under the cursor or under focus.The key that matches this behavior the closest is KEY_SCREENLOCK.

[ Upstream commit 78f3ac76d9e5219589718b9e4733bee21627b3f5 ]
In the past, Asus firmwares would change the panel backlight directly
through the EC when the display off hotkey (Fn+F7) was pressed, and
only notify the OS of such change, with 0x33 when the LCD was ON and
0x34 when the LCD was OFF. These are currently mapped to
KEY_DISPLAYTOGGLE and KEY_DISPLAY_OFF, respectively.Most recently the EC on Asus most machines lost ability to toggle the
LCD backlight directly, but unless the OS informs the firmware it is
going to handle the display toggle hotkey events, the firmware still
tries change the brightness through the EC, to no effect. The end result
is a long list (at Endless we counted 11) of Asus laptop models where
the display toggle hotkey does not perform any action. Our firmware
engineers contacts at Asus were surprised that there were still machines
out there with the old behavior.Calling WMNB(ASUS_WMI_DEVID_BACKLIGHT==0x00050011, 2) on the _WDG device
tells the firmware that it should let the OS handle the display toggle
event, in which case it will simply notify the OS of a key press with
0x35, as shown by the DSDT excerpts bellow.Scope (_SB)

[ Upstream commit 684238d79ad85c5e19a71bb5818e77e329912fbc ]
To fix:
acerhdf: unknown (unsupported) BIOS version Gateway /LT31 /v1.3307 , please report, aborting!
As can be seen in the context, the BIOS registers haven't changed in
the previous versions, so the assumption is they won't have changed
in this last update for this somewhat older platform either.Cc: Peter Feuerer

[ Upstream commit 8d98b1ef368feeb7720b8b9b6f3bd93f2ad892bc ]
On some Goldmont based systems such as ASRock J3455M the BIOS may not
enable the IPC1 device that provides access to the PMC and PUNIT. In
such scenarios, the IOSS and PSS resources from the platform device can
not be obtained and result in a invalid telemetry_plt_config which is an
internal data structure that holds platform config and is maintained by
the telemetry platform driver.This is also applicable to the platforms where the BIOS supports IPC1
device under debug configurations but IPC1 is disabled by user or the
policy.This change allows user to know the reason for not seeing entries under
/sys/kernel/debug/telemetry/* when there is no apparent failure at boot.Cc: Matt Turner

Commit 57e94c8b974db2d83c60e1139c89a70806abbea0 caused cros-ec keyboard events
be truncated on many chromebooks so that Left and Right keys on Column 12 were
always 0. Use ret as memcpy len to fix this.The old code was using ec_dev->event_size, which is the event payload/data size
excluding event_type header, for the length of the memcpy operation. Use ret
as memcpy length to avoid the off by one and copy the whole msg->data.Fixes: 57e94c8b974d ("mfd: cros-ec: Increase maximum mkbp event size")

Pull x86 platform driver updates from Andy Shevchenko:
- The driver for Silead touchscreen configurations has been renamed
from silead_dmi to touchscreen_dmi since it starts supporting other
touchscreens which require some DMI quirksIt also gets expanded to cover cases for Chuwi Vi10, ONDA V891W,
Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets.- Another bunch of changes is related to Mellanox platform code to
allow user space to communicate with Mellanox for system control and
monitoring purposes. The driver notifies user on hotplug device
signal receiving.- ASUS WMI drivers recognize lid flip action on UX360, and correctly
toggles airplane mode LED. In addition the keyboard backlight toggle
gets support.- ThinkPad ACPI driver enables support for calculator key (on at least
P52). It also has been fixed to support three characters model
designators, which are used for modern laptops. Earlier the battery,
marked as BAT1, on ThinkPad laptops has not been configured properly,
which is fixed. On the opposite the multi-battery configurations now
probed correctly.- Dell SMBIOS driver starts working on some Dell servers which do not
support token interface. The regression with backlight detection has
also been fixed. In order to support dock mode on some laptops, Intel
virtual button driver has been fixed. The last but not least is the
fix to Intel HID driver due to changes in Dell systems that prevented
to use power button.* tag 'platform-drivers-x86-v4.19-1' of git://git.infradead.org/linux-platform-drivers-x86: (47 commits)

Pull core signal handling updates from Eric Biederman:
"It was observed that a periodic timer in combination with a
sufficiently expensive fork could prevent fork from every completing.
This contains the changes to remove the need for that restart.This set of changes is split into several parts:
- The first part makes PIDTYPE_TGID a proper pid type instead
something only for very special cases. The part starts using
PIDTYPE_TGID enough so that in __send_signal where signals are
actually delivered we know if the signal is being sent to a a group
of processes or just a single process.- With that prep work out of the way the logic in fork is modified so
that fork logically makes signals received while it is running
appear to be received after the fork completes"* 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (22 commits)

Pull MIPS updates from Paul Burton:
"Here are the main MIPS changes for 4.19.An overview of the general architecture changes:
- Massive DMA ops refactoring from Christoph Hellwig (huzzah for
deleting crufty code!).- We introduce NT_MIPS_DSP & NT_MIPS_FP_MODE ELF notes &
corresponding regsets to expose DSP ASE & floating point mode state
respectively, both for live debugging & core dumps.- We better optimize our code by hard-coding cpu_has_* macros at
compile time where their values are known due to the ISA revision
that the kernel build is targeting.- The EJTAG exception handler now better handles SMP systems, where
it was previously possible for CPUs to clobber a register value
saved by another CPU.- Our implementation of memset() gained a couple of fixes for MIPSr6
systems to return correct values in some cases where stores fault.- We now implement ioremap_wc() using the uncached-accelerated cache
coherency attribute where supported, which is detected during boot,
and fall back to plain uncached access where necessary. The
MIPS-specific (and unused in tree) ioremap_uncached_accelerated() &
ioremap_cacheable_cow() are removed.- The prctl(PR_SET_FP_MODE, ...) syscall is better supported for SMP
systems by reworking the way we ensure remote CPUs that may be
running threads within the affected process switch mode.- Systems using the MIPS Coherence Manager will now set the
MIPS_IC_SNOOPS_REMOTE flag to avoid some unnecessary cache
maintenance overhead when flushing the icache.- A few fixes were made for building with clang/LLVM, which now
sucessfully builds kernels for many of our platforms.- Miscellaneous cleanups all over.
And some platform-specific changes:
- ar7 gained stubs for a few clock API functions to fix build
failures for some drivers.- ath79 gained support for a few new SoCs, a few fixes & better
gpio-keys support.- Ci20 now exposes its SPI bus using the spi-gpio driver.
- The generic platform can now auto-detect a suitable value for
PHYS_OFFSET based upon the memory map described by the device tree,
allowing us to avoid wasting memory on page book-keeping for
systems where RAM starts at a non-zero physical address.- Ingenic systems using the jz4740 platform code now link their
vmlinuz higher to allow for kernels of a realistic size.- Loongson32 now builds the kernel targeting MIPSr1 rather than
MIPSr2 to avoid CPU errata.- Loongson64 gains a couple of fixes, a workaround for a write
buffering issue & support for the Loongson 3A R3.1 CPU.- Malta now uses the piix4-poweroff driver to handle powering down.
- Microsemi Ocelot gained support for its SPI bus & NOR flash, its
second MDIO bus and can now be supported by a FIT/.itb image.- Octeon saw a bunch of header cleanups which remove a lot of
duplicate or unused code"* tag 'mips_4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (123 commits)

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().Acked-by: Andy Shevchenko

A couple of drivers produced build errors after the mod_devicetable.h
header was split out from the platform_device one, e.g.drivers/media/platform/davinci/vpbe_osd.c:42:40: error: array type has incomplete element type 'struct platform_device_id'
drivers/media/platform/davinci/vpbe_venc.c:42:40: error: array type has incomplete element type 'struct platform_device_id'This adds the inclusion where needed.
