From ffed15b889a4d8cfb8c324e238bf308757b1995b Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sun, 30 Aug 2020 15:51:55 +0200 Subject: [PATCH] ARM: dts: exynos: Add CPU cooling in Exynos4412 Origen Add missing cooling devices for CPU thermal zones in Exynos4412 Origen board. This allows to scale down CPU frequency (and voltage) in case of thermal pressure.
