[Perry Yuan]

From: Perry Yuan <perry_yuan@xxxxxxxx>

Hi All,
This patch set is a new driver for dell mobile platform ,which has the
hardware privacy feature.

For micmute led control, the hotkey is Fn + F4, it is a hardware based
mute state, and new privacy will prevent micphone void input from
hardware layer, any application cannot get voice data when micmute
activated. 

Camera mute use a new hardware design to control the camrea shutter.
When video is muted, no OS application should be functionally able to
capture images of the person/environment in front of the system
