Subject: [asus-nb-wmi] thermal device detected by asus-nb-wmi platform driver

Hi,

I booted Ubuntu13.10 onto ASUS T100 Tablet and upgraded it with upstream
kernel (3.14.0-rc7+). There is a thermal device under
/sys/devices/platform/asus-nb-wmi.

root@...0:~/linux# tree /sys/class/hwmon/
/sys/class/hwmon/
├── hwmon0 -> ../../devices/platform/coretemp.0/hwmon/hwmon0
└── hwmon1 -> ../../devices/platform/asus-nb-wmi/hwmon/hwmon1

root@...0:/sys/devices/platform/asus-nb-wmi# ls
cpufv driver hwmon input modalias power subsystem uevent

root@...0:~/linux# sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +38.0°C (high = +90.0°C, crit = +90.0°C)
Core 1: +38.0°C (high = +90.0°C, crit = +90.0°C)
Core 2: +39.0°C (high = +90.0°C, crit = +90.0°C)
Core 3: +38.0°C (high = +90.0°C, crit = +90.0°C)

asus-isa-0000
Adapter: ISA adapter
temp1: +6280.0°C

I didn't get any information about thermal interface in
"Documentation/ABI/testing/sysfs-platform-asus-wmi". Is this a thermal
sensor? If it's the fact, how can I change the environment so that this
sensor gives me variable data?

Thanks,
baolu
