Description:
------------
ASUS mainboards publish hardware monitoring information via Super I/O
chip and the ACPI embedded controller (EC) registers. Some of the sensors
are only available via the EC.

ASUS WMI interface provides a method (BREC) to read data from EC registers,
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:

1. Chipset (PCH) temperature
2. CPU package temperature
3. Motherboard temperature
4. Readings from the T_Sensor header
5. VRM temperature
6. CPU_Opt fan RPM
7. Chipset fan RPM
8. Readings from the "Water flow meter" header (RPM)
9. Readings from the "Water In" and "Water Out" temperature headers
10. CPU current
