From 718b4ca160cfabf8913b44b50f9903755e82f166 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Mon, 16 Apr 2018 12:11:57 +0200 Subject: [PATCH] thermal: exynos: remove parsing of samsung, tmu_[first, second]_point_trim properties All SoCs use the same values (25, 85) for trim points (except Exynos5440 which currently specifices value 70 for the second trim point -> it seems to be a mistake because documentation uses value 85 and two points based trimming has never been used by the driver for this SoC anyway) so just make it explicit and remove parsing of samsung,tmu_[first,second]_point_trim properties. There should be no functional changes caused by this patch.
