Subject: [thermal PATCH v15 1/9] drivers: thermal: tsens: Don't hardcode sensor slope
Date: Tue, 20 Apr 2021 20:33:35 +0200
Message-ID: <20210420183343.2272-2-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20210420183343.2272-1-ansuelsmth@gmail.com>

Function compute_intercept_slope hardcode the sensor slope to
SLOPE_DEFAULT. Change this and use the default value only if a slope is
not defined. This is needed for tsens VER_0 that has a hardcoded slope
table.
