+(event based hotkey or event config interface):
+a. add a event based hotkey(event) :
+echo "0:bus::action:method:num:num" > event_config
+
+b. delete a event based hotkey(event):
+echo "1:::::num:num" > event_config

+c. modify a event based hotkey(event):
+echo "2:bus::action:method:num:num" > event_config

+2. /proc/acpi/hotkey/poll_config
+(polling based hotkey or event config interface):
+a.add a polling based hotkey(event) :
+echo "0:bus:method:action:method:num" > poll_config
+this adding command will create a proc file
+/proc/acpi/hotkey/method, which is used to get
+result of polling.

+echo "event_num:event_type:event_argument" >
+ /proc/acpi/hotkey/action.
+The result of the execution of this aml method is
