Commit 53147b6cabee5e8d1997b5682fcc0c3b72ddf9c2 ("toshiba_acpi: Fix
hotkeys registration on some toshiba models") fixed an issue on some
laptops regarding hotkeys registration, however, if failed to address
the initialization of the hotkey_event_type variable, and thus, it can
lead to potential unwanted effects as the variable is being checked.
This patch initializes such variable to avoid such unwanted effects.

Since v3.0 kernel, acer-wmi driver auto detects internal 3G device and
provides the threeg rfkill interface. So the sysfs interface of 3G is
no longer necessary now.
The 7b8aca65 patch added kernel information log to remind to user space
for the threeg sysfs interface will be removed in 2012, then b58b9ffc patch
updated the interface removing time to 2014.
I think the 3 years lead time is enough for user space application to use
rfkill instead of sysfs interface to control 3G device.
This patch removes code about threeg sysfs interface. And it also removes the
unused interface sysfs that exposes which ACPI-WMI method used by acer-wmi
driver on the machine. The information is already exposed by the acer-wmi
initial log.

Toshiba laptops that feature WMI events for hotkeys were left unsupported
by the toshiba_acpi driver, however, commit a88bc06e5aec ("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).

The IRQF_NO_SUSPEND flag is used to identify the interrupts that should
be left enabled so as to allow them to work as expected during the

The driver currently uses the hotkey enabling value of 0x09 to enable
hotkey events, but windows uses a different value (0x01).
All Toshiba laptops accept the following "hotkey" parameters:
0x01 - Enable hotkey and system events.
0x03 - Enable system events only.
0x09 - Enable hotkey events only.
0x0b - Disable (hotkey and system) events.
This patch changes the default hotkey enabling value from 0x09 to 0x01,
enabling both the hotkey and system events.

Do not write initialize magic on systems that do not have

Add a new test function, hp_wmi_bios_2008_later() & simplify

Commit a2b3471b5b13 ("toshiba_acpi: Use the Hotkey Event Type function
for keymap choosing") changed the *setup_keyboard function to query for
the Hotkey Event Type to help choose the correct keymap, but turns out
that here are certain Toshiba models out there not implementing this
feature, and thus, failing to continue the input device registration and
leaving such laptops without hotkey support.
This patch changes such check, and instead of returning an error if
the Hotkey Event Type is not present, we simply inform userspace about it,
changing the message printed from err to notice, making the function
responsible for registering the input device to continue.
This issue was found on a Toshiba Portege Z30-B, but there might be
some other models out there affected by this regression as well.

The work performed by wmi_gtoa is equivalent to simply sprintf(out,
"%pUL", in), so one could replace its body by this. However, most
users feed the result directly as a %s argument to some other function
which also understands the %p extensions (they all ultimately use
vsnprintf), so we can eliminate some stack buffers and quite a bit of
code by just using %pUL directly.
In wmi_dev_uevent I'm not sure whether there's room for a
nul-terminator in env->buf, so I've just replaced wmi_gtoa with the
equivalent sprintf call.

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.

acpi_bus_register_driver() already returns an appropriate value (0 on
success, and some negative value on error) to be used in __init functions
so the goto/label is redundant in hpwl_init thus remove it and directly
return the value

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.

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 has two keys labeled with an icon of a touchpad. The first,
reported as 0x6B is next to the power key and the second, reported as
0x6A, is F9 combined with Fn button. When I was pressing the latter, I was
getting "Unknown key 6a pressed" message before applying this patch.
Asus F3M does not support WMI so the commit does not update key mappings
in the asus-nb-wmi.c file.
I have not tested this mapping on any other Asus laptop.

Like some of the other Yoga models the Lenovo Yoga 3 14 does not have a
hw rfkill switch, and trying to read the hw rfkill switch through the
ideapad module causes it to always reported blocking breaking wifi.
This commit adds the Lenovo Yoga 3 14 to the no_hw_rfkill dmi list, fixing
the wifi breakage.

A previous patch added explicit feature checks for support, *SUCCESS*
and *FAILURE to the HCI/SCI *{get, set} functions.
This patch removes some unnedded checks to the driver HCI/SCI
functions given that the default error return value is now set to
-EIO, there is no need to check for other error values other than
the ones currently checking for.

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.

Currently the driver prints "*not supported" if any of the features
queried are in fact not supported, let us print the available
features instead.
This patch removes all instances pr_info printing "*not supported",
and add a new function called "print_supported_features", which will
print the available laptop features.

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.

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.

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.

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
sysfs functions.
