Subject: [PATCH 1/3] thermal: qcom: lmh: Add support for sm8150
Date: Thu,  2 Dec 2021 17:38:00 -0500	[thread overview]
Message-ID: <20211202223802.382068-2-thara.gopinath@linaro.org> (raw)
In-Reply-To: <20211202223802.382068-1-thara.gopinath@linaro.org>

Add compatible to support LMh for sm8150 SoC.
sm8150 does not require explicit enabling for various LMh subsystems.
Move this piece of code under condition that it is executed only
for sdm845 SoC.
