From 6562504dfe4128608b417397b92d7fd943648535 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Fri, 30 Jan 2015 08:26:03 +0900 Subject: [PATCH] ARM: dts: Trip points and sensor configuration data for exynos5440 This commit provides information about Exynos5440 device configuration. Previously this information was available in exynos_tmu_data.c file. Now it is available in the device tree. Such approach allows reusing some common code for thermal.
