 The laptop manual tells us that this key is for screenlock
KEY_TV is now KEY_PROG1

158ca1d75d eeepc-laptop: support for super hybrid engine (SHE)
The older eeepc-acpi driver allowed to control the SHE performance
preset through a ACPI function for just this purpose. SHE underclocks
and undervolts the FSB and undervolts the CPU (at preset 2,
"powersave"), or slightly overclocks the CPU (at preset 0,
"performance"). Preset 1 is the default setting with default clocks and
voltage.

The new eeepc-laptop driver doesn't support it anymore.
The attached patch adds support for it to eeepc-laptop. It's very
straight-forward and almost trivial.

978605c4fd eeepc-laptop: Work around rfkill firmware bug
1) Buggy firmware can change the RFKILL state by itself. This is easily
   detected.  The RFKILL API states that in such cases, we should call
   rfkill_force_state() to notify the core.

   I have reported the bug to Asus. I believe this is the right thing
   to do for robustness, even if this particular firmware bug is fixed.

2) The same bug causes the wireless toggle key to be reported as 0x11
   instead of 0x10.  0x11 is otherwise unused, so it should be safe to
   add this as a new keycode.

The bug is triggered by removing the laptop battery while hibernated.

On resume, the wireless toggle key causes the firmware to toggle the
wireless state itself.  (Also, the key is reported as 0x11 when the
current wireless state is OFF).

This is very poor behaviour because the OS can't predict whether the
firmware is controlling the RFKILL state.

Without this workaround, the bug means users have to press the wireless
toggle key twice to enable, due to the OS/firmware conflict.  (Assuming
rfkill-input or equivalent is being used).  The workaround avoids this.

I believe that acpid scripts which toggle the value of the sysfs state file
when the toggle key is pressed will be rendered ineffective by the bug,
regardless of this workaround.  If they simply toggle the state, when the
firmware has already toggled it, then you will never see a state change.

Tested on "EEEPC 4G" only.

64b86b6583 eeepc-laptop: report brightness control events via the input layer
This maps the brightness control events to one of two keys, either
KEY_BRIGHTNESSDOWN or KEY_BRIGHTNESSUP, as needed.

Some mapping has to be done due to the fact that the BIOS reports them as
<base value> + <current brightness index>; the selection is done according to
the sign of the change in brightness (if this is 0, no keypress is reported).

fbc97e4c5c eeepc-laptop: fix wlan rfkill state change during init
When an rfkill device is registered, the rfkill core will change its
state to the system default. So we need to prepare for state changes
*before* we register it. That means installing the eeepc-specific ACPI
callback which handles the hotplug of the wireless network adaptor.

This problem doesn't occur during normal operation.  You have to

1) Boot with wireless enabled. eeepc-laptop should load automatically.
2) modprobe -r eeepc-laptop
3) modprobe eeepc-laptop

On boot, the default rfkill state will be set to enabled.
With the current core code, step 2) will disable the wireless.
Therefore in step 3), the wireless will change state during registration,
from disabled to enabled.  But without this fix, the PCI device for the
wireless adaptor will not appear.

Plenty of high-profile changes, so it deserves a new version number.

Features added since 0.22:
 *  Restrict unsafe LEDs
 *  New race-less brightness control strategy for IBM ThinkPads
 *  Disclose TGID of driver access from userspace (debug)
 *  Warn when deprecated functions are used

Other changes:
 *  Better debug messages in some subdrivers
 *  Removed "hotkey disable" support, since it breaks the driver
 *  Dropped "ibm-acpi" alias

75bd3bf2ad thinkpad-acpi: fix LED blinking through timer trigger
The set_blink hook code in the LED subdriver would never manage to get
a LED to blink, and instead it would just turn it on.  The consequence
of this is that the "timer" trigger would not cause the LED to blink
if given default parameters.

This problem exists since 2.6.26-rc1.

To fix it, switch the deferred LED work handling to use the
thinkpad-acpi-specific LED status (off/on/blink) directly.

This also makes the code easier to read, and to extend later.

0e501834f8 thinkpad-acpi: rework brightness support
Refactor and redesign the brightness control backend...

In order to fix bugzilla #11750...

Add a new brightness control mode: support direct NVRAM checkpointing
of the backlight level (i.e. store directly to NVRAM without the need
for UCMS calls), and use that together with the EC-based control.
Disallow UCMS+EC, thus avoiding races with the SMM firmware.

Switch the models that define HBRV (EC Brightness Value) in the DSDT
to the new mode.  These are: T40-T43, R50-R52, R50e, R51e, X31-X41.

Change the default for all other IBM ThinkPads to UCMS-only.  The
Lenovo models already default to UCMS-only.

a4d5effcc7 thinkpad-acpi: restrict access to some firmware LEDs
Some of the ThinkPad LEDs indicate critical conditions that can cause
data loss or cause hardware damage when ignored (e.g. force-ejecting
a powered up bay; ignoring a failing battery, or empty battery; force-
undocking with the dock buses still active, etc).

On almost all ThinkPads, LED access is write-only, and the firmware
usually does fire-and-forget signaling on them, so you effectively
lose whatever message the firmware was trying to convey to the user
when you override the LED state, without any chance to restore it.

Restrict access to all LEDs that can convey important alarms, or that
could mislead the user into incorrectly operating the hardware.  This
will make the Lenovo engineers less unhappy about the whole issue.

Allow users that really want it to still control all LEDs, it is the
unaware user that we have to worry about.

2586d5663d thinkpad-acpi: remove HKEY disable functionality
The HKEY disable functionality basically cripples the entire event
model of the ThinkPad firmware and of the thinkpad-acpi driver.
Remove this functionality from the driver.  HKEY must be enabled at
all times while thinkpad-acpi is loaded, and disabled otherwise.

For sysfs, according to the sysfs ABI and the thinkpad-acpi sysfs
rules of engagement, we will just remove the attributes.  This will be
done in two stages: disable their function now, after two kernel
releases, remove the attributes.

For procfs, we call WARN().  If nothing triggers it, I will simply
remove the enable/disable commands entirely in the future along with
the sysfs attributes.

I don't expect much, if any fallout from this.  There really isn't any
reason to mess with hotkey_enable or with the enable/disable commands
to /proc/acpi/ibm/hotkey, and this has been true for years...

0b3f6109f0 dell-wmi: new driver for hotkey control

pressed, but maybe other uses will appear over time.
