Subject: [PATCH 06/11] DT: arm64: exynos: add support for thermal trip irq-mode
Date: Tue, 16 Oct 2018 16:56:17 +0200	[thread overview]
Message-ID: <20181016145647eucas1p206c068806214535da339588d77cbdfa5~eHqLYh2dR2135021350eucas1p2K@eucas1p2.samsung.com> (raw)
In-Reply-To: <1539701782-26852-1-git-send-email-l.luba@partner.samsung.com>

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.
