Joe Perches efd85cf86a thinkpad_acpi: Remove side effects from vdbg_printk -> no_printk macro
vdbg_printk when not using CONFIG_THINKPAD_ACPI_DEBUG uses
no_printk which produces no logging output but always
evaluates arguments.

Change the macro to surround the no_printk call with
	do { if (0) no_printk(...); } while (0)
to avoid the unnecessary argument evaluations.

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.

Matt Fleming 420b54de25 mfd: watchdog: iTCO_wdt: Expose watchdog properties using platform data
Intel Sunrisepoint (Skylake PCH) has the iTCO watchdog accessible across
the SMBus, unlike previous generations of PCH/ICH where it was on the
LPC bus. Because it's on the SMBus, it doesn't make sense to pass around
a 'struct lpc_ich_info', and leaking the type of bus into the iTCO
watchdog driver is kind of backwards anyway.

This change introduces a new 'struct itco_wdt_platform_data' for use
inside the iTCO watchdog driver and by the upcoming Intel Sunrisepoint
code, which neatly avoids having to include lpc_ich headers in the i801
i2c driver.

This change is overdue because lpc_ich_info has already found its way
into other TCO watchdog users, notably the intel_pmc_ipc driver where
the watchdog actually isn't on the LPC bus as far as I can see.

A simple translation layer is provided for converting from the existing
'struct lpc_ich_info' inside the lpc_ich mfd driver.

Sebastian Krzyszkowiak 6d212b8adc ideapad-laptop: add alternative representation for Yoga 2 to DMI table
There is at least one (mine) Yoga 2 Pro in existence that has incorrect
product version stored in DMI (reading as "INVALID"), causing it to not be
recognized as Yoga 2 by ideapad-laptop module, which in turn causes
non-existent hardware rfkills to be always reported as blocked.

This change adds a second check by board name, which is "Yoga2".
Looks like it also happens to be "INVALID" on some other Yoga 2 machines
where product version is correct instead, so the original check is left
intact to catch both cases.

Asus F3M does not support WMI so the commit does not update key mappings

Azael Avalos e1a949c1b9 toshiba_acpi: Refactor *{get, set} functions return value
This patch refactors the return value of the driver *{get, set}
functions, since the driver default error value is -EIO.

All the functions now check for TOS_FAILURE, TOS_NOT_SUPPORTED and
TOS_SUCCESS.

On TOS_FAILURE a pr_err message is printed informing the user of the
error (no change was made to this, except the check was added to the
functions not checking for this).

On TOS_NOT_SUPPORTED we now return -ENODEV immediately (some
functions were returning -EIO and some other were not checking)

On TOS_SUCCESS* we now return 0 (as a side effect, a new success value
was added, since some functions return one instead of zero to
indicate success).

As a special case, the LED functions now check for *FAILURE on
*set, and check for TOS_FAILURE and TOS_SUCCESS on *get with their
"default" return value set to LED_OFF.

Also the {lcd, video}_proc* functions were adapted to reflect these
changes to their parent HCI functions.

Azael Avalos ea215a3f90 toshiba_acpi: Change *available functions return type
This patch changes the *available functions return type from int to
void.

The checks for support of their respective features are done inside
such functions and there was no need to return anything as we can
flag the queried feature as supported inside these functions.

The code was adapted accordingly to these changes and two new
variables were created and another was changed from uint to bool.

Also, the function toshiba_acceleremoter_supported was renamed to
toshiba_accelerometer_available to maintain the naming consistency on
the driver.

Nick Dyer 7f3884f7de Input: atmel_mxt_ts - use deep sleep mode when stopped
The hardcoded 0x83 CTRL setting overrides other settings in that byte,
enabling extra reporting that may not be useful on a particular platform.

Implement improved suspend mechanism via deep sleep. By writing zero to
both the active and idle cycle times the maXTouch device can be put into a
deep sleep mode, using minimal power. It is necessary to issue a calibrate
command after the chip has spent any time in deep sleep, however a soft
reset is unnecessary.

Use the old method on Chromebook Pixel via platform data option.

This patch also deals with the situation where the power configuration is
zero on probe, which would mean that the device never wakes up to execute
commands.

After a config download, the T7 power configuration may have changed so it
is necessary to re-read it.

Sascha Hauer 17e8351a77 thermal: consistently use int for temperatures
The thermal code uses int, long and unsigned long for temperatures
in different places.

Using an unsigned type limits the thermal framework to positive
temperatures without need. Also several drivers currently will report
temperatures near UINT_MAX for temperatures below 0°C. This will probably
immediately shut the machine down due to overtemperature if started below
0°C.

'long' is 64bit on several architectures. This is not needed since INT_MAX °mC
is above the melting point of all known materials.

Consistently use a plain 'int' for temperatures throughout the thermal code and
the drivers. This only changes the places in the drivers where the temperature
is passed around as pointer, when drivers internally use another type this is
not changed.

Azael Avalos 3e07e5baa2 toshiba_acpi: Add set_fan_status function
This patch adds a new function named "set_fan_status" to complement
its get* counterpart, as well as to avoid code duplication between
"fan_proc_write" and "fan_store".

Also, both functions (get*, set*) are now checking for TOS_FAILURE,
TOS_NOT_SUPPORTED and TOS_SUCCESS (to be on par with the rest of the
HCI/SCI functions), printing an error message, returning -ENODEV and
zero respectively.

The proc and sysfs functions were updated to reflect these changes as
well, returning -EIO for proc, and propagating the error value on the

Azael Avalos fc5462f852 toshiba_acpi: Add /dev/toshiba_acpi device
There were previous attempts to "merge" the toshiba SMM module to the
toshiba_acpi one, they were trying to imitate what the old toshiba
module does, however, some models (TOS1900 devices) come with a
"crippled" implementation and do not provide all the "features" a
"genuine" Toshiba BIOS does.

This patch adds a new device called toshiba_acpi, which aim is to
enable userspace to access the SMM on Toshiba laptops via ACPI calls.

Creating a new convenience _IOWR command to access the SCI functions
by opening/closing the SCI internally to avoid buggy BIOS, while at
the same time providing backwards compatibility.

Older programs (and new) who wish to access the SMM on newer models
can do it by pointing their path to /dev/toshiba_acpi (instead of
/dev/toshiba) as the toshiba.h header was modified to reflect these
changes as well as adds all the toshiba_acpi paths and command,
however, it is strongly recommended to use the new IOCTL for any
SCI command to avoid any buggy BIOS.

Pull module_platform_driver replacement from Paul Gortmaker:
 "Replace module_platform_driver with builtin_platform driver in non
  modules.

  We see an increasing number of non-modular drivers using
  modular_driver() type register functions.  There are several downsides
  to letting this continue unchecked:

   - The code can appear modular to a reader of the code, and they won't
     know if the code really is modular without checking the Makefile
     and Kconfig to see if compilation is governed by a bool or
     tristate.

   - Coders of drivers may be tempted to code up an __exit function that
     is never used, just in order to satisfy the required three args of
     the modular registration function.

   - Non-modular code ends up including the <module.h> which increases
     CPP overhead that they don't need.

   - It hinders us from performing better separation of the module init
     code and the generic init code.

  So here we introduce similar macros for builtin drivers.  Then we
  convert builtin drivers (controlled by a bool Kconfig) by making the
  following type of mapping:

    module_platform_driver()       --->  builtin_platform_driver()
    module_platform_driver_probe() --->  builtin_platform_driver_probe().

  The set of drivers that are converted here are just the ones that
  showed up as relying on an implicit include of <module.h> during a
  pending header cleanup.  So we convert them here vs adding an include
  of <module.h> to non-modular code to avoid compile fails.  Additonal
  conversions can be done asynchronously at any time.

  Once again, an unused module_exit function that is removed here
  appears in the diffstat as an outlier wrt all the other changes"

Pali Rohár b8830a4e71 dell-laptop: Fix allocating & freeing SMI buffer page
This commit fix kernel crash when probing for rfkill devices in dell-laptop
driver failed. Function free_page() was incorrectly used on struct page *
instead of virtual address of SMI buffer.

This commit also simplify allocating page for SMI buffer by using
__get_free_page() function instead of sequential call of functions
alloc_page() and page_address().

Pull power management and ACPI updates from Rafael Wysocki:
 "The rework of backlight interface selection API from Hans de Goede
  stands out from the number of commits and the number of affected
  places perspective.  The cpufreq core fixes from Viresh Kumar are
  quite significant too as far as the number of commits goes and because
  they should reduce CPU online/offline overhead quite a bit in the
  majority of cases.

  From the new featues point of view, the ACPICA update (to upstream
  revision 20150515) adding support for new ACPI 6 material to ACPICA is
  the one that matters the most as some new significant features will be
  based on it going forward.  Also included is an update of the ACPI
  device power management core to follow ACPI 6 (which in turn reflects
  the Windows' device PM implementation), a PM core extension to support
  wakeup interrupts in a more generic way and support for the ACPI _CCA
  device configuration object.

  The rest is mostly fixes and cleanups all over and some documentation
  updates, including new DT bindings for Operating Performance Points.

  There is one fix for a regression introduced in the 4.1 cycle, but it
  adds quite a number of lines of code, it wasn't really ready before
  Thursday and you were on vacation, so I refrained from pushing it on
  the last minute for 4.1.
