Exynos4? 4 trip points? Beside that other comments apply as well. Best regards, Krzysztof

This patch adds support for new flash which indicates that trip point triggers irq when temperature is met. Exynos5433 supports 8 trip point which will trigger irq. Above that number other trip points should be registered without 'irq-mode' flag. That will force the thermal framework to start polling the temperature sensor under configured conditions and handle the trip point.
