From 5d2bb6621caa66f6912f91b4565ee945aea20258 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sun, 30 Aug 2020 15:51:46 +0200 Subject: [PATCH] ARM: dts: exynos: Add CPU cooling in Exynos4210 Origen Add missing cooling devices for CPU thermal zones in Exynos4210 Origen board. This allows to scale down CPU frequency (and voltage) in case of thermal pressure.
