From bd031c725d7499b6c77be554c6b4a7cb79f1b765 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sun, 30 Aug 2020 15:51:47 +0200 Subject: [PATCH] ARM: dts: exynos: Add CPU cooling in SMDKv310 Add missing cooling devices for CPU thermal zones in Exynos4210 SMDKv310 board. This allows to scale down CPU frequency (and voltage) in case of thermal pressure.
