	help

	  This driver has the information about the virtual sensors used by

	  QTI chipset's and registers the virtual sensors to a thermal zone.

	  The virtual sensor information includes the underlying thermal

	  sensors to query for temperature and the aggregation logic to

	  determine the virtual sensor temperature.
