Subject: [PATCH RFC 3/8] thermal: thermal_of: Extend thermal dt driver to support bi-directional monitoring of a thermal trip point.
Date: Wed, 16 Sep 2020 23:22:21 -0400	[thread overview]
Message-ID: <20200917032226.820371-4-thara.gopinath@linaro.org> (raw)
In-Reply-To: <20200917032226.820371-1-thara.gopinath@linaro.org>

Introduce of_thermal_get_trip_monitor_type to return the direction
of monitoring of a thermal trip point. Also translate the DT information
regarding trip point monitor direction into the thermal framework.
