Peripheral Control (ec_odm)
/dev/ec_odm is a device that is OEM specific, so the following info will be AC100/AZ100 specific. 
Through /dev/ec_odm you can control many things like touchpad, or leds. It doesn't seem to exist 
in nVidia's sources and ATM no toshiba sources.

Files in /proc/test_program/* (see below) provides a high-level access to EC-ODM.

You can access /dev/ec_odm with the program test-ec (sourcecode: test-ec.c).
Usage: ./test-ec 0xc0043006 2 (to turn off backlight)

So, there are multiple ioctl IDs, and all of these commands take an int as parameter

Tested parameters:

LEDs: 0xc0043002 . This handles notification (side) LED.
Values from 0 to 7 are different effects
8 disables the led.

TouchPad: 0xc0043003 . This disables/enables touchpad, and touchpad scroll.
0 get touchpad status
1 enables touchpad
2 disables touchpad
3 get scroll status
4 enable scroll
5 disable scroll

Only 5/4 seem to work accurately.

Do not use the backlight command before the previous backlight command has finished. Doing so may cause wrong behaviour.
Append (wtf is that name?) : 0xc0043006 :
0 is called shutdown but doesn't seem to do anything
1 enables it
2 turn off the backlight

Untested parameters:

EC: 0xc0043004
getRecoveryPin: 0
setRecoveryPin: enable=1,disable=2
setLidControl: enable=0xc, disable=0xd
setPowerButtonControl: enable=0xa; disable=0xb

Keyboard: 0xc0043001
getKeyboardLayout: 1
setKeyboardLayout: unknown
