Haswell-based Fujitsu laptops (Lifebook E734/E744/E754) have a touchpad
toggle hotkey (Fn+F4) which is handled transparently to the operating
system: while an ACPI notification is sent to FUJ02B1 when Fn+F4 is
pressed, touchpad state is properly toggled without any explicit support
for this operation in fujitsu-laptop.
Skylake-based models (Lifebook E736/E746/E756) also have that hotkey,
but the touchpad is not toggled transparently to the operating system.
When Fn+F4 is pressed, an ACPI notification is sent to FUJ02E3. A
subsequent call to S000 (FUNC_RFKILL) can be used to determine whether
the touchpad toggle hotkey was pressed so that an input event can be
sent to userspace.
Relevant ACPI code:
Method (_L21, 0, NotSerialized)
{
...
If (AHKF)
{
Notify (\_SB.FEXT, 0x80)
}
...
}
Method (S000, 3, Serialized)
{
Name (_T_0, Zero)
Local0 = Zero
While (One)
{
_T_0 = Arg0
If (_T_0 == Zero)
{
Local0 |= 0x04000000
Local0 |= 0x02000000
Local0 |= 0x00020000
Local0 |= 0x0200
Local0 |= 0x0100
Local0 |= 0x20
}
ElseIf (_T_0 == One)
{
...
If (AHKF & 0x08)
{
Local0 |= 0x04000000
AHKF ^= 0x08
}
...
} ...
Break
}
Return (Local0)
}
Pressing Fn+F4 raises GPE 0x21 and sets bit 3 in AHKF. This in turn
results in bit 26 being set in the value returned by FUNC_RFKILL called
with 1 as its first argument. On Skylake-based models, bit 26 is also
set in the value returned by FUNC_RFKILL called with 0 as its first
argument (this value is saved in fujitsu_hotkey->rfkill_supported upon
module initialization), which suggests that this bit is set on models
which do not handle touchpad toggling transparently to the operating
system.
Note that bit 3 is cleared in AHKF once FUNC_RFKILL is called with 1 as
its first argument, which requires fujitsu-laptop to handle this hotkey
in a different manner than the other, GIRB-based hotkeys: two input
events (press and release) are immediately sent once Fn+F4 is pressed.

vdbg_printk() always prefixes the log messages it generates with
"FUJ02B1", which can be misleading, because it might have been called
while handling a notify for ACPI device FUJ02E3 or during module
initialization etc. Employ pr_fmt() to prefix debug messages with the
module name instead and thus avoid confusion.

This patch reworks code for generating sparse keymap and processing WMI
events. It unifies procedure for generating sparse keymap and also unifies
big switch code for processing WMI events of different types. After this
patch dell-wmi driver does not differ between "old" and "new" hotkey type.
It constructs sparse keymap table with all WMI codes. It is because on some
laptops (e.g. Dell Latitude E6440) ACPI/firmware send both event types (old
and new).
Each WMI code in sparse keymap table is prefixed by 16bit event type, so it
does not change functionality on laptops with "old" hotkey support (those
without scancodes in DMI).
This allow us to distinguish between same WMI codes with different types in
sparse keymap. Thanks to this WMI events of type 0x0011 were moved from big
switch into sparse keymap table too.
This patch also fixes possible bug in parsing WMI event buffer introduced
in commit 5ea2559726b7 ("dell-wmi: Add support for new Dell systems"). That
commit changed buffer type from int* to u16* without fixing code. More at:

ACPI DSDT tables have defined other WMI codes, but does not contain any
description when those codes are emitted. Some other codes can be found in
logs on internet. In this patch are all which I saw, but lot of them are
not tested properly (e.g. for duplicate events with AT keyboard). Now we
have all WMI event codes at one place and in future after proper testing
those codes can be correctly enabled or disabled...

This patch adds the Power Management Controller driver as a PCI driver
for Intel Core SoC architecture.
This driver can utilize debugging capabilities and supported features
as exposed by the Power Management Controller.
Please refer to the below specification for more details on PMC features.
http://www.intel.in/content/www/in/en/chipsets/100-series-chipset-datasheet-vol-2.html
The current version of this driver exposes SLP_S0_RESIDENCY counter.
This counter can be used for detecting fragile SLP_S0 signal related
failures and take corrective actions when PCH SLP_S0 signal is not
asserted after kernel freeze as part of suspend to idle flow
(echo freeze > /sys/power/state).
Intel Platform Controller Hub (PCH) asserts SLP_S0 signal when it
detects favorable conditions to enter its low power mode. As a
pre-requisite the SoC should be in deepest possible Package C-State
and devices should be in low power mode. For example, on Skylake SoC
the deepest Package C-State is Package C10 or PC10. Suspend to idle
flow generally leads to PC10 state but PC10 state may not be sufficient
for realizing the platform wide power potential which SLP_S0 signal
assertion can provide.
SLP_S0 signal is often connected to the Embedded Controller (EC) and the
Power Management IC (PMIC) for other platform power management related
optimizations.
In general, SLP_S0 assertion == PC10 + PCH low power mode + ModPhy Lanes
power gated + PLL Idle.
As part of this driver, a mechanism to read the SLP_S0_RESIDENCY is exposed
as an API and also debugfs features are added to indicate SLP_S0 signal
assertion residency in microseconds.
echo freeze > /sys/power/state
wake the system

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for kernel cycle v4.7:
Core infrastructural changes:
- Support for natively single-ended GPIO driver stages.
This means that if the hardware has registers to configure open
drain or open source configuration, we use that rather than (as we
did before) try to emulate it by switching the line to an input to
get high impedance.
This is also documented throughly in Documentation/gpio/driver.txt
for those of you who did not understand one word of what I just
wrote.
- Start to do away with the unnecessarily complex and unitelligible
ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB, another
evolutional artifact from the time when the GPIO subsystem was
unmaintained.
Archs can now just select GPIOLIB and be done with it, cleanups to
arches will trickle in for the next kernel. Some minor archs ACKed
the changes immediately so these are included in this pull request.
- Advancing the use of the data pointer inside the GPIO device for
storing driver data by switching the PowerPC, Super-H Unicore and
a few other subarches or subsystem drivers in ALSA SoC, Input,
serial, SSB, staging etc to use it.
- The initialization now reads the input/output state of the GPIO
lines, so that each GPIO descriptor knows - if this callback is
implemented - whether the line is input or output. This also
reflects nicely in userspace "lsgpio".
- It is now possible to name GPIO producer names, line names, from
the device tree. (Platform data has been supported for a while).
I bet we will get a similar mechanism for ACPI one of those days.
This makes is possible to get sensible producer names for e.g.
GPIO rails in "lsgpio" in userspace.
New drivers:
- New driver for the Loongson1.
- The XLP driver now supports Broadcom Vulcan ARM64.
- The IT87 driver now supports IT8620 and IT8628.
- The PCA953X driver now supports Galileo Gen2.
Driver improvements:
- MCP23S08 was switched to use the gpiolib irqchip helpers and now
also suppors level-triggered interrupts.
- 74x164 and RCAR now supports the .set_multiple() callback
- AMDPT was converted to use generic GPIO.
- TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
support the new single ended callback for open drain and in some
cases open source.
- Implement the .get_direction() callback for a few more drivers like
PL061, Xgene.
Cleanups:
- Paul Gortmaker combed through the drivers and de-modularized those
who are not really modules.
- Move the GPIO poweroff DT bindings to the power subdir where they
belong.
- Rename gpio-generic.c to gpio-mmio.c, which is much more to the
point. That's what it is handling, nothing more, nothing less"

Lightbar attributes are hidden if the ID of the device is not 0 (the
assumption being that 0 = cros_ec = might have a lightbar, 1 = cros_pd =
hide); however, sometimes these devices get IDs 1 and 2 (or something
else) instead of IDs 0 and 1. This prevents the lightbar attributes from
appearing when they should.
Proposed change is to instead check whether the name assigned to the
device is CROS_EC_DEV_NAME (true for cros_ec, false for cros_pd).

Prevent memory scribble by checking that ioctl buffer size parameters
are sane.
Without this check, on 32 bits system, if .insize = 0xffffffff - 20 and
.outsize the amount to scribble, we would overflow, allocate a small
amounts and be able to write outside of the malloc'ed area.
Adding a hard limit allows argument checking of the ioctl. With the
current EC, it is expected .insize and .outsize to be at around 512 bytes
or less.
