Stop logging unknown event / unknown keycode messages on suspend /
resume on a Toshiba Portege Z830:
1. The Toshiba Portege Z830 sends a 0x8e event when the power button
is pressed, ignore this.
2. The Toshiba Portege Z830 sends a 0xe00 hotkey event on resume from
suspend, ignore this.

For bus-based driver, device removal is implemented as:
1 device_remove()->
2 bus->remove()->
3 driver->remove()
Driver core needs no inform from callee(bus driver) about the
result of remove callback. In that case, commit fc7a6209d571
("bus: Make remove callback return void") forces bus_type::remove
be void-returned.
Now we have the situation that both 1 & 2 of calling chain are
void-returned, so it does not make much sense for 3(driver->remove)
to return non-void to its caller.
So the basic idea behind this change is making remove() callback of
any bus-based driver to be void-returned.
This change, for itself, is for device drivers based on acpi-bus.

Right now, is impossible for battery hook callbacks
to access instance-specific data, forcing most drivers
to provide some sort of global state. This however is
difficult for drivers which can be instantiated multiple
times and/or are hotplug-capable.
Pass a pointer to the battery hook to those callbacks
for usage with container_of().

Some Toshibas have a broken acpi-video interface for brightness control, so
far these have been using a special workaround in drivers/acpi/acpi_video.c
which gets activated by the disable_backlight_sysfs_if module-param/quirks.
The recent x86/acpi backlight refactoring has broken this workaround:
1. This workaround relies on acpi_video_get_backlight_type() returning
acpi_video so that the acpi_video code actually runs; and
2. this relies on the actual native GPU driver to offer the sysfs
backlight interface to userspace.
After the refactor this breaks since the native driver will no
longer register its backlight-device if acpi_video_get_backlight_type()
does not return native and making it return native breaks 1.
Keeping the acpi_video backlight handling on resume active, while not
using it to set the brightness, is necessary because it does a _BCM
call on resume which is necessary to turn the panel back on on resume.
Looking at the DSDT shows that this _BCM call results in a Toshiba
HCI_SET HCI_LCD_BRIGHTNESS call, which turns the panel back on.
This commit makes toshiba_acpi do a HCI_SET HCI_PANEL_POWER_ON call
on resume on the affected models, so that the (now broken)
acpi_video disable_backlight_sysfs_if workaround will no longer
be necessary.
Note this uses HCI_PANEL_POWER_ON instead of HCI_LCD_BRIGHTNESS
to avoid changing the configured brightness level.

This commit adds the ACPI battery hook which in turns adds the sysfs
entries.
Because the Toshiba laptops only support two modes (eco or normal), which
in testing correspond to 80% and 100% we simply round to the nearest
possible level when set.
It is possible that Toshiba laptops other than the Z830 has different set
points for the charging. If so, a quirk table could be introduced in the
future for this. For now, assume that all laptops that support this feature
work the same way.
Tested on a Toshiba Satellite Z830.

This commit adds the internal functions to control the Toshiba laptop.
Unlike for example ThinkPads where this control is granular here it is
just off/on. When off it charges to 100%. When on it charges to about 80%.
Controlling this setting is done via HCI register 0x00ba. Setting to value
1 will result in limiting the charing to 80% of the battery capacity,
while setting it to 0 will allow charging to 100%.
Reading the current state is a bit weird, and needs a 1 set in the last
position of the query for whatever reason. In addition, the read may
return 0x8d20 (Data not available) rarely, so a retry mechanism is needed.
According to the Windows program used to control the feature the setting
will not take effect until the battery has been discharged to around 50%.
However, in my testing it takes effect as soon as the charge drops below
80%. On Windows Toshiba branded this feature as "Eco charging".

This add the internal feature detection and reading function for fan RPM.
The approach is based on tracing ACPI calls using AMLI (a tracer/debugger
built into ACPI.sys) while using the Windows cooling self-test software.
The call used is {HCI_GET, 0x45, 0, 1, 0, 0} which returns:
{0x0, 0x45, fan_rpm, probably_max_rpm, 0x0, 0x0}
What is probably the max RPM is not currently used.

acpi_video_set_dmi_backlight_type() is troublesome because it may end up
getting called after other backlight drivers have already called
acpi_video_get_backlight_type() resulting in the other drivers
already being registered even though they should not.
In case of the acpi_video backlight, acpi_video_set_dmi_backlight_type()
actually calls acpi_video_unregister_backlight() since that is often
probed earlier, leading to userspace seeing the acpi_video0 class
device being briefly available, leading to races in userspace where
udev probe-rules try to access the device and it is already gone.
In case of toshiba_acpi there are no DMI quirks to move to
acpi/video_detect.c, but it also (ab)uses it for transflective
displays. Adding transflective display support to video_detect.c would
be quite involved. But luckily there are only 2 known models with
a transflective display, so we can just add DMI quirks for those.

The change passes the parent device to the iio_device_alloc() call. This
also updates the devm_iio_device_alloc() call to consider the device object
as the parent device by default.
Having it passed like this, should ensure that any IIO device object
already has a device object as parent, allowing for neater control, like
passing the 'indio_dev' object for other stuff [like buffers/triggers/etc],
and potentially creating iiom_xxx(indio_dev) functions.
With this patch, only the 'drivers/platform/x86/toshiba_acpi.c' needs an
update to pass the parent object as a parameter.
In the next patch all devm_iio_device_alloc() calls will be handled.

Second generation keyboard backlight (type 2) laptops can switch
on the keyboard LED on their own via hardware/firmware, but the
LED subsystem is unaware of such change since the LED interface
was only being created on first generation keyboard backlight
(type 1) laptops.
This patch creates the LED interface for second gen keyboards
and calls the *_hw_changed API whenever userspace changes the
state of the keyboard backlight LED.
While we are at it, remove an unneeded asignment to the acpi_dev
struct under *_kbd_bl_work, and also update the kbd_event_generated
variable in the main toshiba struct instead of the global struct.

This patch moves all the multiple line variable declaration to a
single line declaration (except variables being initialized)
following the reverse tree order, to conform to the practices
of the kernel.
[dvhart: corrected a couple minor inconsistencies in declaration ordering]

Now that we have proper support for the acceleromeer under the IIO
subsystem, the _position_ sysfs file is now deprecated.
This patch removes all code related to the position sysfs entry.

This patch adds the accelerometer axis data to the IIO subsystem.
Currently reporting the X, Y and Z values, as no other data can be
queried given the fact that the accelerometer chip itself is hidden
behind the Toshiba proprietary interface.

Commit 52cbae0127ad ("toshiba_acpi: Change default Hotkey enabling value")
changed the hotkeys enabling value, as it was the same value Windows uses,
however, it turns out that the value tells the EC that the driver will now
take care of the hardware events like the physical RFKill switch or the
pointing device toggle button.
This patch reverts such commit by changing the default hotkey enabling
value to 0x09, which enables hotkey events only, making the hardware
buttons working again.
Fixes bugs 113331 and 114941.

Some laptop models have working hotkeys without the need of the driver
to activate them.
This patch adds a module parameter to tell the driver not to register
the hotkeys.
The new parameter is useful in DE less installations or where the DE
does not handle the hotkeys (see bug 99501).

This patch adds support to query and set the "Cooling Method" feature,
which basically changes how the system fan behaves, depending on the
supported cooling methods.
Depending on the laptop model, these are the (so far...) available
cooling methods:
- Maximum Performance
- Performance
- Battery Optimized

Certain Toshiba models with the second generation keyboard backlight
(type 2) do not generate the keyboard backlight changed event (0x92),
and thus, the sysfs entries are never being updated.
This patch adds a workquee and a global boolean variable to address
the issue.
For those models that do generate the event, the sysfs entries are
being updated via the *notify function and the boolean is set to
true to avoid a second call to update the entries.
For those models that do not generate the event, the workquee is
used to update the sysfs entries and also to emulate the event via
netlink, to make userspace aware of such change.

A previuos patch added WWAN support to the driver, allowing to query
and set the device status.
This patch adds RFKill support for the recently introduced WWAN device,
making use of the WWAN and *wireless_status functions to query the
killswitch and (de)activate the device accordingly to its status.

Toshiba laptops with WWAN devices installed cannot use the device unless
it is attached and powered, similar to how Toshiba Bluetooth devices
work.
This patch adds support to WWAN devices, introducing three functions,
one to query the overall status of the wireless devices (RFKill, WLAN,
BT, WWAN), the second queries WWAN support, and finally the third
(de)activates the device.

If transflective backlight is supported and the brightness is zero
(lowest brightness level), the set_lcd_brightness function will activate
the transflective backlight, making the LCD appear to be turned off.
This patch fixes the issue by incrementing the brightness level, and
by doing so, avoiding the activation of the tranflective backlight.

The driver uses genetlink to inform userspace of events generated by
the system, but the data passed is always zero as there is no data to
pass, except for the hotkey event.
This patch propagates the hotkey value via genetlink so userspace can
make use of it.

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.

The function toshiba_acpi_setup_keyboard currently has two u32 variables
used to store the Hotkey Event Type and the result of the HCI_SYSTEM_EVENT
query.
This patch removes those two variables, as we already have a global
variable named "hotkey_event_type" and the result of the HCI_SYSTEM_EVENT
query can be checked directly from the function.

This patch adds the 0x prefix to the values printed by such function, the
values are already being printed in hex, but without the prefix, causing
confusion, even though the file under Documentation/ABI clearly states
that hey are hex values.
Simply add the 0x prefix to avoid such confusion.
