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" ?
