[PATCH/RFC 0/3] thermal: rcar_gen3_thermal: Apply shared interrupts for thermal sensors

[Khiem Nguyen]

This patchset intents to improve thermal driver operation in interrupt mode,
which has been introduced in [1].

The original idea is using 1 interrupt for each thermal sensor, to detect both up
and down temperature. It caused issue when the temperature is changing rapidly.

The new idea is about using shared interrupt I/F for all three sensors.
Two interrupts will be set to detect temperature up and down. When interrupt occurs,
the temperature will be updated in all 3 sensors, if the temperature value is changed. 

All comments are welcome.
