+Description:
+ Human presence detection (HPD) enable/disable.
+ When HPD is enabled, the device will be able to detect the
+ presence of a human and will send an interrupt that can be
+ used to wake the system from a low power state.
+ When HPD is disabled, the device will not be able to detect
+ the presence of a human.
+
+ Access: Read/Write
+ Valid values: enabled/disabled
