    Subject[PATCH v2 10/11] arm: dts: exynos5422: add support for thermal trip irq-mode
    Date
    This patch adds support for new flag which indicates
    that trip point triggers IRQ when temperature is met.
    Exynos5422 supports 4 trip points which will trigger IRQ.
    Additional trip points should be registered without 'irq-mode' flag.
