You most likely want to preserve it, while keeping a sensible
polling frequency, so that userspace will be aware of the current
CPU temperature. <100> sounds like a sensible value here.

Temperature sensor's present in IPQ5424 supports interrupts.
Hence no need to configure polling frequency.
I will remove polling-delay-passive/polling-delay.

Correct.

No, that interrupt firing signifies crossing the temp threshold (meaning
no updates beyond that) or the tsens watchdog barking.

An interrupt fires when the temperature crosses a threshold.

Which means you can't monitor the temperature at runtime
without polling..

Hi Konrad,
I got the point. Will configure polling-delay-passive with 100.
