Subject: [PATCH 4/5] thermal: exynos: fixed the efuse min/max value for exynos5422
Date:   Tue, 17 Jul 2018 10:12:21 +0000
Message-Id: <1531822342-4293-4-git-send-email-linux.amoon@gmail.com>
In-Reply-To: <1531822342-4293-1-git-send-email-linux.amoon@gmail.com>
References: <1531822342-4293-1-git-send-email-linux.amoon@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

e-fuse range min~max range is 16~76. if e-fuse value is out of
this range, then thermal sensor may not sense thermal data properly.
