Corentin Chary d358cb55a4 eeepc-wmi: never load if legacy device is enabled
If legacy device (SB.ATKD - ASUS010) used by eeepc-laptop
is enabled, don't allow eeepc-wmi to load because:
- eeepc-laptop may be loaded, and can conflict with
  eeepc-wmi (they both try to register eeepc::touchpad
  led for example).
- the WMI interface is inteded to be used when the OS is
  not detected as Win 7. And when this is the case, the
  ASUS010 device is disabled.

Corentin Chary 4c4edfa3d3 eeepc-wmi: claim eeepc-wmi maintainership
Since eeepc-wmi has currently no official maintainer, I claim
maintainership of this driver, and add it to the acpi4asus project.

Corentin Chary 8c1b2d83e8 eeepc-wmi: add debugfs entries
eeepc-wmi/    - debugfs root directory
  dev_id      - current dev_id
  ctrl_param  - current ctrl_param
  devs        - call DEVS(dev_id, ctrl_param) and print result
  dsts        - call DSTS(dev_id)  and print result

DEVS and DSTS are the main functions used in eeepc-wmi, this
will allow to test new features without patching the drivers.

Corentin Chary ba48fdb969 eeepc-wmi: add rfkill support for wlan, bluetooth and 3g
wimax support is missing because I don't have any DSDT

Corentin Chary 27c136c873 eeepc-wmi: rework eeepc_wmi_init and eeepc_wmi_exit
The old code was using platform_driver.probe to initialize
eeepc_wmi context. That's a mistake because if probe fail,
eeepc_platform_register() won't tell anyone, and chaos will happen.

Wrap add and remove code inside eeepc_wmi_add() / eeepc_wmi_remove(),
and try to use the static platform_device only in eeepc_wmi_init()
and eeepc_wmi_exit()

The code is now very similar to eeepc-laptop, except eeepc_laptop_add
and eeepc_laptop_remove are called from acpi_driver, not module
init/exit functions, but WMI doesn't provide such functionalities (yet ?).

Chris Bagwell 7f80d734b3 eeepc-wmi: Add cpufv sysfs interface
eeepc-laptop provides a sysfs interface to read and control what it
calls cpufv.  When WMI is enabled, the ACPI interface changes slightly
and becames a write-only control with 3 valid values.

Expose cpufv again to allow for user space utils that can extended battery
life noticably and come a little closer to parity with eeepc-laptop.

Write-only is OK for most user space apps because read status was
mostly used to prevent unneeded mode changes.  Since this same check
to ignore changes to same mode also exists in the DSDT then it was
wasted ACPI call.

acpi_osi="!Windows 2009" can be used for get back eeepc-laptop's
read support of cpufv for debugging things such as behaviour
during resume.

This patch was tested with EEE PC 1005PE by monitoring powertop output while
writing values of "0", "1", and "2" and by reviewing the decompiled DSDT of
an 1201NL and comparing it to 1005PE's DSDT.

Chris Bagwell eda1748418 eeepc-wmi: add additional hotkeys
Added 4 hotkeys using same keymap values as eeepc-latop.
These are mousepad toggle, resolution change, screen off,
and task manager.  These were tested on 1005PE and are the
Fn-F3, F4, F7, and F9, respectively.

Also, added a new hot key for power toggles (Fn-Space on 1005PE)
and is meant to drive cpufv interface from userspace.
