From 60e203ecb1faf62efe369ca2bc22630bcda88bdc Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Tue, 26 Aug 2014 10:31:02 +0900 Subject: [PATCH] thermal: samsung: Exynos5260 and Exynos5420 should not use TRIM_RELOAD flag Currently these SoCs claim TRIM_RELOAD support but don't have triminfo_ctrl register address defined in their struct exynos_tmu_registers entries. This causes incorrect write of value "1" to data->base + 0x00 address (which happens to be TRIMINFO register). Additionally according to the documentation that I have neither Exynos5260 nor Exynos5420 support/require TRIM_RELOAD feature. Thus fix the aforementioned issue by removing TMU_SUPPORT_TRIM_RELOAD flag for both Exynos5260 and Exynos5420.
