Subject: [PATCH 11/11] DT: arm: exynos: add support for thermal trip irq-mode
Date: Tue, 16 Oct 2018 16:56:22 +0200	[thread overview]
Message-ID: <20181016145653eucas1p2c408ac952ed5c351c98398fa3df373e6~eHqRiOtv50773307733eucas1p20@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.
