Just fyi, I had a short discussion with Eric Miao about this. The 
conclusion was:

The patch itself is OK. It's just lacking some features, but these can 
be added later. The driver supports thermal reading only, but not 
accurate as the thermal calibration data is burned into the FUSE, and 
differ from chip to chip. At the moment only incorrect thermal 
information will be exposed to user space. The patch is lacking 
connections to cpufreq and cpu hotplug, but those could be added later, too.

Best regards

Dirk
