Does this mean "thermal_zone doesn't use lm-senser" ?

I'd prefer to say of_thermal registered thermal_zone doesn't use
lm-
sensor.
If you're really want to see hwmon interface, I think you should
use
thermal API (thermal_zone_device_register) directly.

Thank you for your feedback.
My driver is supporting both of_thermal and thermal API.
So, switching is not a big deal.

But can you teach me why of_thermal doesn't use lm-senser ??

I don't know if there is a solid reason that we can not expose the
hwmon interface. But just like the comment says, "/* No hwmon because
there might be hwmon drivers registering */", given that of_thermal
just parses THERMAL data of device tree, it is reasonable to me for
exposing thermal interfaces only.

thanks,
