Subject: [PATCH v3 3/5] drivers: thermal: tsens: allow configuring min and max trips
Date: Tue,  3 May 2022 22:05:28 +0200	[thread overview]
Message-ID: <20220503200530.4019673-3-robimarko@gmail.com> (raw)
In-Reply-To: <20220503200530.4019673-1-robimarko@gmail.com>

IPQ8074 and IPQ6018 dont support negative trip temperatures and support
up to 204 degrees C as the max trip temperature.

So, instead of always setting the -40 as min and 120 degrees C as max
allow it to be configured as part of the features.
