+Description:
+		Display which dell hardware level privacy devices are supported
+		“Dell Privacy” is a set of HW, FW, and SW features to enhance
+		Dell’s commitment to platform privacy for MIC, Camera, and
+		ePrivacy screens.
+		The supported hardware privacy devices are:
+
+		Attributes:
+			Microphone Mute:
+				Identifies the local microphone can be muted by hardware, no applications
+				is available to capture system mic sound
+
+			Camera Shutter:
+				Identifies camera shutter controlled by hardware, which is a micromechanical
+				shutter assembly that is built onto the camera module to block capturing images
+				from outside the laptop
+
+		Values:
+
+			supported:
+				The privacy device is supported by this system
+
+			unsupported:
+				The privacy device is not supported on this system
+
+		For example to check which privacy devices are supported::
+
+		    # cat /sys/bus/wmi/drivers/dell-privacy/6932965F-1671-4CEB-B988-D3AB0A901919/dell_privacy_supported_type

+
+		Values:
+			muted:
+				Identifies the privacy device is turned off
+				and cannot send stream to OS applications
+
+			unmuted:
+				Identifies the privacy device is turned on,

+
+		For example to check all supported current privacy device states::
+
+		    # cat /sys/bus/wmi/drivers/dell-privacy/6932965F-1671-4CEB-B988-D3AB0A901919/dell_privacy_current_state
