From 173ab0310fb44b73093b7aed9a9e6c4916bc059d Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sun, 30 Aug 2020 15:51:57 +0200 Subject: [PATCH] ARM: dts: exynos: Add CPU cooling in Tiny4412 Add missing cooling devices for CPU thermal zones in Exynos4412 Tiny4412 board. This allows to scale down CPU frequency (and voltage) in case of thermal pressure.
