Add new attributes in thermal syfs when a thermal drivers provides
callbacks for them and CONFIG_THERMAL_USER_EVENT_INTERFACE is defined.
These attribute allow user space to stop polling for temperature.
These attributes are:
- temp_thres_low: Specify a notification temperature for a low
Add new attribute in the thermal syfs for setting temperature sampling
interval when CONFIG_THERMAL_USER_EVENT_INTERFACE is defined. The default
value is 0, which means no polling.
At this interval user space will get an event THERMAL_TEMP_SAMPLE with
temperature sample. This reuses existing
I presented this idea during LPC 2018.

There was broad agreement about this.
At that time, there was no use case for non x86 systems. But now there is

This change adds an optional feature to add a new device entry
