Subject: [PATCHv3 18/23] drivers: thermal: tsens: Common get_temp() learns to do ADC conversion
Date: Wed, 20 Mar 2019 18:47:58 +0530
Message-ID: <389f9e70f715e2884418d77c9ff06fad6878eacc.1553086065.git.amit.kucheria@linaro.org> (raw)
In-Reply-To: <cover.1553086065.git.amit.kucheria@linaro.org>

get_temp() learns to return temperature regardless of whether it is
returned as ADC code or direct temperature.
