New intel_turbo_max_3 driver, providing max core frequency information to the
 scheduler. Intel PMC APL support, s0ix read API, and fixes.
 
 New Silead touchscreen platform touchscreen descriptions. Additional hotkey
 support for the intel-hid driver.
 
 New model support for dell-laptop and hp_accel.

 This tag includes the already merged branch: led_brightness_hw_changed from:
     git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds into HEAD
 Which includes the following commit:
     7de50ae leds: class: Add new optional brightness_hw_changed attribute
 needed for the thinkpad_acpi changes noted below
 
 This is the first time a pdx86 pull request has included a merge of an immutable
 branch from another subsystem, as we have previously either waited for the
 dependency to be merged, or asked the other maintainer to merge dependent
 changes. As this included three patches specifically to thinkpad_acpi, we
 decided to try the merge and apply model.

Hans de Goede cef9dd85ac platform/x86: add support for devices with Silead touchscreens
On ACPI based tablets, the ACPI touchscreen node only contains info on
the gpio and the irq, and is missing any info on the axis. This info is
expected to be built into the tablet model specific version of the driver
shipped with the os-image for the device.

Add support for getting the missing info from a table built into the
driver, using dmi data to identify which entry of the table to use and
add info for the CUBE iwork8 Air and Jumper EZpad mini3 tablets on which
this code was tested / developed.

Srinivas Pandruvada 4ec567b8dd platform/x86: Support Turbo Boost Max 3.0 for non HWP systems
On platforms supporting Intel Turbo Boost Max Technology 3.0, the
maximum turbo frequencies (turbo ratio) of some cores in a CPU package
may be higher than the other cores in the same package.  In that case,
better performance can be achieved by making the scheduler prefer to run
tasks on the CPUs with higher max turbo frequencies.

On Intel® Broadwell Xeon systems, it is optional to turn on HWP
(Hardware P-States). When HWP is not turned on, the BIOS doesn't
present required CPPC (Collaborative Processor Performance Control)
tables. This table is used to get the per CPU core maximum performance
ratio and inform scheduler (in cpufreq/intel_pstate driver).

On such systems the maximum performance ratio can be read via over
clocking (OC) mailbox interface for each CPU. This interface is not
architectural and can change for every model of processors.

This driver reads maximum performance ratio of each CPU and set up
the scheduler priority metrics. In this way scheduler can prefer CPU
with higher performance to schedule tasks.

Benjamin Tissoires 1a64b719d3 platform/x86: Introduce button support for the Surface 3
The Surface 3 is not following the ACPI spec for PNP0C40, but nearly.
The device is connected to a I2C device that might have some magic
but we don't know about.
Just create the device after the enumeration and use the declared GPIOs
to provide button support.

This driver is just an adaptation of drivers/input/misc/soc_button_array.c

The Surface Pro 3 is using an ACPI driver and matches against the bid
of the device ("VGBI"). To prevent this incompatible driver to be used
on the Surface Pro, we add a match on the Surface 3 bid "TEV2".

Benjamin Tissoires 3dda3b3798 platform/x86: Add custom surface3 platform device for controlling LID
The LID state provided by ACPI on the Surface 3 is not accurate.
The ACPI node doesn't get notified on LID open, which means the
LID input switch stays close most of the time.

Fortunatelly, there is a WMI method which directly queries the
GPIO underneath the LID state, so it's far more reliable than ACPI.
To get the notifications that the LID was opened/closed, we can
rely on the ACPI notification of the touchscreen: the DSDT shows
that the touchscreen will get notified on close/open as it also
controls its _STA method.

Note that we need to set the tag "power-switch" to the LID
input node through a udev rule for logind to accept it:

SUBSYSTEM=="input", KERNEL=="event*", KERNELS=="surface3-wmi", \

Rajneesh Bhardwaj b740d2e923 platform/x86: Add PMC Driver for Intel Core SoC
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.

João Paulo Rechi Vita f6a6bbae04 platform/x86: Add Asus Wireless Radio Control driver
Some Asus notebooks like the Asus E202SA and the Asus X555UB have a
separate ACPI device for notifications from the airplane mode hotkey.
This device is called "Wireless Radio Control" in Asus websites and ASHS
in the DSDT, and its ACPI _HID is ATK4002 in the two models mentioned
above.

For these models, when the airplane mode hotkey (Fn+F2) is pressed, a
query 0x0B is started in the Embedded Controller, and all this query does
is a notify ASHS with the value 0x88 (for acpi_osi >= "Windows 2012"):

	Scope (_SB.PCI0.SBRG.EC0)
	{
		(...)
		Method (_Q0B, 0, NotSerialized)  // _Qxx: EC Query

			If ((MSOS () >= OSW8))

Azael Avalos 14991fc7df platform/x86: Toshiba WMI Hotkey Driver
Toshiba laptops that feature WMI events for hotkeys were left unsupported
by the toshiba_acpi driver, however, commit a88bc06e5a ("toshiba_acpi:
Avoid registering input device on WMI event laptops") added hardware
support for such laptops, but the hotkeys are not handled there.

This driver adds support for hotkey monitoring on certain Toshiba laptops
that manage the hotkeys via WMI events instead of the Toshiba
Configuration Interface (TCI).

The toshiba_acpi driver and this one can co-exist, as this only takes
care of hotkeys, while the proper takes care of hardware related stuff.

Currently the driver is under the EXPERIMENTAL flag, as the keymap
and the notify function are incomplete (due to lack of hardware to test).

Chen Yu 2508a45a92 surface pro 3: Add support driver for Surface Pro 3 buttons
Since Surface Pro 3 does not follow the specs of "Windows ACPI Design
Guide for SoC Platform", code in drivers/input/misc/soc_array.c can
not detect these buttons on it. According to bios implementation,
Surface Pro 3 encapsulates these buttons in a device named "VGBI",
with _HID "MSHW0028". When any of the buttons is pressed, a specify
ACPI notification code for this button will be delivered to "VGBI". For
example, if power button is pressed down, ACPI notification code of 0xc6
will be sent by Notify(VGBI, 0xc6).

This patch leverages "VGBI" to distinguish different ACPI notification
code from Power button, Home button, Volume button, then dispatches these
code to input layer. Lid is already covered by acpi button driver, so
there's no need to rewrite.

David E. Box 997ab407d2 X86 platform: New BayTrail IOSF-SB MBI driver
Current Intel SOC cores use a MailBox Interface (MBI) to provide access to unit
devices connected to the system fabric. This driver implements access to this
interface on BayTrail platforms. This is a requirement for drivers that need
access to unit registers on the platform (e.g. accessing the PUNIT for power
management features such as RAPL). Serialized access is handled by all exported
routines with spinlocks.

The API includes 3 functions for access to unit registers:

int bt_mbi_read(u8 port, u8 opcode, u32 offset, u32 *mdr)
int bt_mbi_write(u8 port, u8 opcode, u32 offset, u32 mdr)
int bt_mbi_modify(u8 port, u8 opcode, u32 offset, u32 mdr, u32 mask)

port:	indicating the unit being accessed
opcode:	the read or write port specific opcode
offset:	the register offset within the port
mdr:	the register data to be read, written, or modified
mask:	bit locations in mdr to change

Returns nonzero on error

Note: GPU code handles access to the GFX unit. Therefore access to that unit
with this driver is disallowed to avoid conflicts.

Matthew Garrett 5c7f80f755 Add trivial driver to disable Intel Smart Connect
Intel Smart Connect is an Intel-specific ACPI interface for configuring
devices to wake up at regular intervals so they can pull down mail or other
internet updates, and then go to sleep again. If a user enables this in
Windows and then reboots into Linux, the device may wake up if it's put to
sleep. Since there's no Linux userland support for any of this, the machine
will then remain awake until something else puts it back to sleep.

I haven't figured out all that much about how this works (there's a bunch
of different ACPI calls available on the device), but this seems to be
enough to turn it off. We can add more features to this driver if anyone
ever cares about figuring out what the rest of the calls do or writing some
Linux userspace to implement the rest of it.

Intel Rapid Start Technology is a firmware-based suspend-to-disk
implementation. Once placed in S3, the device will wake once either a
timeout elapses or the battery reaches a critical level. It will then resume
to the firmware and copy the contents of RAM to a specialised partition, and
then power off the machine. If the user turns the machine back on the
firmware will copy the contents of the partition back to RAM and then resume
from S3 as normal.

This driver provides an interface for configuring the wakeup events and
timeout. It still requires firmware support and an appropriate suspend
partition.
