-driver/acpi/hotkey.c implement:
-1. /proc/acpi/hotkey/event_config
-(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.
-
-b.delete a polling based hotkey(event):
-echo "1:::::num" > event_config
-
-c.modify a polling based hotkey(event):
-echo "2:bus:method:action:method:num" > poll_config

-3./proc/acpi/hotkey/action
-(interface to call aml method associated with a
-specific hotkey(event))
-echo "event_num:event_type:event_argument" >
- /proc/acpi/hotkey/action.
-The result of the execution of this aml method is
-attached to /proc/acpi/hotkey/poll_method, which is dynamically
-created. Please use command "cat /proc/acpi/hotkey/polling_method"
-to retrieve it.

-Note: Use cmdline "acpi_generic_hotkey" to over-ride
-platform-specific with generic driver.
