+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.
