Nguyen" , Catalin Marinas , Simon Horman List-Id: devicetree@vger.kernel.org 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.
