From c0dfbb115cf07f5912f3db04c91baf35cab67335 Mon Sep 17 00:00:00 2001 From: Amit Daniel Kachhap Date: Sat, 21 Jul 2012 10:53:49 +1000 Subject: [PATCH] thermal: exynos5: add exynos5 thermal sensor driver support Insert exynos5 TMU sensor changes into the thermal driver. Some exynos4 changes are made generic for exynos series.
