+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.
+
+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. VRM heatsink fan RPM
+8. Chipset fan RPM
+9. Readings from the "Water flow meter" header (RPM)
+10. Readings from the "Water In" and "Water Out" temperature headers
+11. CPU current
+
+Sensor values are read from EC registers, and to avoid race with the board
+firmware the driver acquires ACPI mutex, the one used by the WMI when its
+methods access the EC.
+
+Module Parameters
+-----------------
+ * mutex_path: string
+		The driver holds path to the ACPI mutex for each board (actually,
+		the path is mostly identical for them). If ASUS changes this path
+		in a future BIOS update, this parameter can be used to override
+		the stored in the driver value until it gets updated.

-ASUS mainboards publish hardware monitoring information via Super I/O

-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

-9. Readings from the "Water In" and "Water Out" temperature headers
-10. CPU current
