Here is what the Linux driver looks like : 

  powerpc/powernv: handle OPAL_SUCCESS return in opal_sensor_read
  hwmon: (ibmpowernv) replace AMBIENT_TEMP by TEMP
  hwmon: (ibmpowernv) add a get_sensor_type() routine
  hwmon: (ibmpowernv) add a convert_opal_attr_name() routine
  hwmon: (ibmpowernv) change create_hwmon_attr_name() prototype
  hwmon: (ibmpowernv) do not use the OPAL index for hwmon attribute
    names
  hwmon: (ibmpowernv) add support for the new device tree
  hwmon: (ibmpowernv) add a label attribute
  hwmon: (ibmpowernv) cleanup some redundant code

I will wait for comments on this OPAL patchset before sending.
