From d00671c3ae3f4bfdfbdd1413150ad1a3a135ad1e Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Thu, 13 Nov 2014 16:01:14 +0100 Subject: [PATCH] thermal: exynos: add get_con_reg() helper Factor out code for preparing TMU_CONTROL register value from exynos_tmu_control() into get_con_reg(). This is a preparation for introducing per-SoC type tmu_control method. There should be no functional changes caused by this patch.
