		Description:
		------------
		ASUS mainboards publish hardware monitoring information via WMI interface.

		ASUS WMI interface provides a methods to get list of sensors and values of
		such, which is utilized by this driver to publish those sensor readings to the
		HWMON system.

		The driver is aware of and reads the following sensors:
		* CPU Core Voltage,
		* CPU SOC Voltage,
		* DRAM Voltage,
		* VDDP Voltage,
		* 1.8V PLL Voltage,
		* +12V Voltage,
		* +5V Voltage,
		* 3VSB Voltage,
		* VBAT Voltage,
		* AVCC3 Voltage,
		* SB 1.05V Voltage,
		* CPU Core Voltage,
		* CPU SOC Voltage,
		* DRAM Voltage,
		* CPU Fan RPM,
		* Chassis Fan 1 RPM,
		* Chassis Fan 2 RPM,
		* Chassis Fan 3 RPM,
		* HAMP Fan RPM,
		* Water Pump RPM,
		* CPU OPT RPM,
		* Water Flow RPM,
		* AIO Pump RPM,
		* CPU Temperature,
		* CPU Socket Temperature,
		* Motherboard Temperature,
		* Chipset Temperature,
		* Tsensor 1 Temperature,
		* CPU VRM Temperature,
		* Water In,
		* Water Out,
		* CPU VRM Output Current.

		Known Issues:
		* The WMI implementation in some of Asus' BIOSes is buggy. This can result in
		fans stopping, fans getting stuck at max speed, or temperature readouts
		getting stuck. This is not an issue with the driver, but the BIOS. The Prime
		X470 Pro seems particularly bad for this. The more frequently the WMI
		interface is polled the greater the potential for this to happen. Until you
		have subjected your computer to an extended soak test while polling the
		sensors frequently, don't leave you computer unattended. Upgrading to new
		BIOS version with method version greater than or equal to two should
		rectify the issue.
		* A few boards report 12v voltages to be ~10v.
