21 ASUS mainboards publish hardware monitoring information via Super I/O
22 chip and the ACPI embedded controller (EC) registers. Some of the sensors
23 are only available via the EC.
25 ASUS WMI interface provides a method (BREC) to read data from EC registers,
26 which is utilized by this driver to publish those sensor readings to the
27 HWMON system. The driver is aware of and reads the following sensors:
29 1. Chipset (PCH) temperature
30 2. CPU package temperature
31 3. Motherboard temperature
32 4. Readings from the T_Sensor header
36 8. Readings from the "Water flow meter" header (RPM)
37 9. Readings from the "Water In" and "Water Out" temperature headers
