As discussed on LKML some notion of 'function' is needed in
LED naming. This patch adds this to the documentation and

This is based on the 2004 out-of-tree work of Jamey Hicks, to add
support via WMI for controlling the jog dial and wireless on these
tablets.
v1:
Original release
v2:
As per Joshua Wise's comments, change bluetooth to jogdial (an error from
the original driver).

This is a driver for newer Acer (and Wistron) laptops. It adds wireless
radio and bluetooth control, and on some laptops, exposes the mail LED and
LCD backlight.
v1:
* Initial release
v2:
* Replace left over ACPI references with WMI
* Add GUID based autoloading (depends on future work to WMI)
* Add DMI based autoloading (backup solution until WMI sysfs/ class
work is available)
* Checkpatch fixes
v3:
* Add new EC quirks for Aspire 3100 & 5100, and Extensa 5220
v4:
* Simplified internal handling of WMID and AMW0 devices
* Add autodetection for bluetooth and maximum brightness on AMW0 V2 and
WMID laptops.
v5:
* Add EC quirk for Medion MD 98000
* Add autodetection for AMW0, and mail LED on AMW0 and AMW0 V2.
* Improve error handling
* Fix AMW0 V2 bluetooth and wireless, by using both WMID and AMW0 methods
to ensure that the correct value is always set.
v6:
* Fix 'use before initialisation' bug with quirks.
v7
* Fix bug on AMW0 where acer-wmi would exit if a mail LED was not
detected.
* Add Acer Aspire 9110 mail LED support
* Fix section mismatch warnings

Implement poll()/select() support through sysfs_notify() for some key
attributes which userspace might want to poll() or select() on.
In order to let userspace know poll()/select() support is available for an
attribute, the thinkpad-acpi sysfs interface version is also bumped up.
Further changes that add poll()/select() capabilities to any pre-existing
attributes will also increment the sysfs interface version.

Handle some HKEY events that the firmware uses to report the reason for a
wake up, and to also notify that the system could go back to sleep (if it
woke up just to eject something from the bay, or to undock).
The driver will report the reason of the last wake up in the sysfs
attribute "wakeup_reason": 0 for "none, unknown, or standard ACPI wake up
event", 1 for "bay ejection request" and 2 for "undock request".
The firmware will also report if the operation that triggered the wake up
has been completed, by issuing an HKEY 0x3003 or 0x4003 event. If the
operation fails, no event is sent. When such a hotunplug sucessfull
notification is issued, the driver sets the attribute
"wakeup_hotunplug_complete" to 1.
While the firmware does tell us whether we are waking from a suspend or
hibernation scenario, the Linux way of hibernating makes this information
not reliable, and therefore it is not reported.
The idea is that if any of these attributes are non-zero, userspace might
want to do something at the end of the "wake up from sleep" procedures,
such as offering to send the machine back into sleep as soon as it is safe
to do so.

now).

The NVRAM polling support for hot keys is reason enough to

Older ThinkPad models do not export some of the hot keys over the
event-based ACPI hot key interface. For these models, one has to poll
the CMOS NVRAM to check the key state at a rate faster than the expected
rate at which the user might repeatedly press the same hot key.
This patch implements this functionality for many of the hotkeys in a
transparent way: hot keys will now Just Work, and the driver knows the
best approach (events or NVRAM polling) to employ, based on the
HKEY.MHKA ACPI method.
Also, the driver can turn off the polling when there are no users for
the hot keys that need such polling.
The NVRAM-based hot keys of the A3x series that have never been
implemented by later models are not supported, to avoid changes in the
keymap of the input devices that could cause headaches in the future.
There is a Kconfig option to avoid compiling the NVRAM polling code, as
it is not very small, and unlikely to be useful on any ThinkPad newer
than a T40, X31 or R52.
This feature is based on a previous effort by Richard Hughes.

Refactor and organize the code a bit for the NVRAM polling support:
1. Split hotkey_get/set into hotkey_status_get/set and hotkey_mask_get/set;
2. Cache the status of hot key mask for later driver use;
3. Make sure the cache of hot key mask is refreshed when needed;
4. log a printk notice when the firmware doesn't set the hot key
mask to exactly what we asked it to;
5. Add proper locking to the data structures.
Only (4) should be user-noticeable, but there is a chance (5) fixes
some unknown/unreported race conditions.

Publish the requirements for keymap changes. This is a documentation
change, only.
Currently, people look at the thinkpad-acpi default keymaps, and think:
"modifying this is a trivial thing, it can't break systems, and there are
keys defined for foo and bar, but the driver has them as KEY_RESERVED.
Must have been an oversight, let me change it."
And since they never get to see the bug reports, because they are not
really a part of the Linux ThinkPad users community (linux-thinkpad
mailinglist, thinkwiki wiki, thinkpad forums) and laptop users are slow
to complain to distros about any breakages...

Starting in 2.6.23...
Several reports from X60 users complained that the default Lenovo keymap
issuing EV_KEY KEY_BRIGHTNESS_UP/DOWN input events caused major issues when
the proper brightness support through ACPI video.c was loaded.
Therefore, remove the generation of these events by default, which is the
right thing for T60, X60, R60, T61, X61 and R61 with their latest BIOSes.
Distros that want to misuse these events into OSD reporting (which requires
an ugly hack from hell in HAL) are welcome to set up the key map they need
through HAL. That way, we don't break everyone else's systems.

set_ibm_param() could OOPS with a NULL pointer derreference if one did not give
any values for a module parameter it handles. This would, of course, cause all
sort of trouble for future modprobing and require a reboot to clean up
properly.
Fix it by returning -EINVAL if no values are given for the parameter, and also
avoid any nastyness from BUG_ON while at it.
