Subject: [PATCH 05/12] thermal: exynos: remove parsing of
 samsung,tmu[_min,_max]_efuse_value properties
Date:   Tue, 06 Mar 2018 15:43:48 +0100

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Since pdata efuse values are SoC (not platform) specific just move
them from platform data to struct exynos_tmu_data instance. Then
remove parsing of samsung,tmu[_,min_,max]_efuse_value properties.

There should be no functional changes caused by this patch.
