The AMW0 function in acer-wmi works on Lenovo ideapad S205 for control
the wifi hardware state. We also found there have a 0x78 EC register
exposes the state of wifi hardware switch on the machine.
So, add this patch to support Lenovo ideapad S205 wifi hardware switch
in acer-wmi driver.

The T101MT Home/Express Gate key autorepeats in hardware, but

This key is different than other hotkeys, having seperate scan
codes for press, release, and hold, so it requires some special
filtering. Press and release events are passed on, and hold events
are ignored since sparse-keymap does not support hardware
autorepeat.
Note that "Home" in the context of this button doesn't mean the
same thing as the usual Home key, and it really isn't clear at
all what is meant by "Home". The manufacurer's description of the
button indicates that it should launch some sort of touch screen
settings interface on short press and apply a desktop rotation on
long press.

longer necessary.
We also plan to remove interface sysfs file that exposed which ACPI-WMI
interface that was used by acer-wmi driver. It will replaced by information
log when acer-wmi initial.
We keep it around for userspace compatibility reasons, schedule removal
in 2012.

This reverts commit a3d77411e8,

It is probably a bad idea to toggle the rfkill for all dell models

Handle events 0x4010 and 0x4011 so that we do not pester users about them.
These events report when the thinkpad is docked/undocked to a native
hotplug dock (i.e. one that does not need ACPI handling, nor is represented
in the ACPI device tree). Such docks are based on USB 2.0/3.0, and also
work as port replicators.
We really want a proper dock class to report these, or at least new input
EV_SW events. Since it is not clear which one to use yet, keep reporting
them as vendor-specific ThinkPad events.
WARNING: As defined by the thinkpad-acpi sysfs ABI rules of engagement, the
vendor-specific events will be REMOVED as soon as generic events are made
available (duplicate events are a big problem), with an appropriate update
to the thinkpad-acpi sysfs/event ABI versioning. Userspace is already
prepared to provide easy backwards compatibility for such changes when
convenient to the distro (see acpi-fakekey).
* Event 0x4010: docking to hotplug dock/port replicator
* Event 0x4011: undocking from hotplug dock/port replicator
Typical usecase would be to trigger display reconfiguration.
Reports mention T410, T510, and series 3 docks/port replicators. Special
thanks to Robert de Rooy for his extensive report and analysis of the
situation.

Handle some user interface events from the newer Lenovo models. We are likely
to do something smart with these events in the future, for now, hide the ones
we are already certain about from the user and userspace both.
* Events 0x6000 and 0x6005 are key-related. 0x6005 is not properly identified
yet. Ignore these events, and do not report them.
* Event 0x6040 has not been properly identified yet, and we don't know if it
is important (looks like it isn't, but still...). Keep reporting it.
* Change the message the driver outputs on unknown 0x6xxx events, as all
recent events are not related to thermal alarms. Degrade log level from
ALERT to WARNING.
Thanks to all users who reported these events or asked about them in a number
of mailing lists. Your help is highly appreciated, even if I did took a lot of
time to act on them. For that I apologise.
I will list those that identified the reasons for the events as "reported-by",
and I apologise in advance if I leave anyone out: it was not done on purpose, I
made the mistake of not properly tagging all event report emails separately,
and might have missed some.

acer-wmi is indiscriminately using the device state from hotkey
events to update the various rfkill states. On the Aspire 1830 this
can result in a soft block on the wlan when the touchpad hotkey is
pressed, as it is reporting a non-zero device state that does not
reflect the wireless status. To fix this, only update rfkill states
when a wlan or bluetooth hotkey is pressed.
