		Video Output Switcher Control
		~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
		2006 luming.yu@intel.com

		The output sysfs class driver provides an abstract video output layer that
		can be used to hook platform specific methods to enable/disable video output
		device through common sysfs interface. For example, on my IBM ThinkPad T42
		laptop, The ACPI video driver registered its output devices and read/write
		method for 'state' with output sysfs class. The user interface under sysfs is:

		linux:/sys/class/video_output # tree .
