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.
