Hi Zhang
Thank you for your help

Thanks. but it seems our system has it.
I noticed that thermal_zone case uses of_parse_thermal_zones() and it has this.
/* No hwmon because there might be hwmon drivers registering */ tzp->no_hwmon = true;
and on thermal_zone_device_register() check this for hwmon
struct thermal_zone_device *thermal_zone_device_register(xxxx) { ... if (!tz->tzp || !tz->tzp->no_hwmon) { result = thermal_add_hwmon_sysfs(tz); ... } ... }
Does this mean "thermal_zone doesn't use lm-senser" ?
