From 1c651356f482ff08f6acef197a362f2e71d55a98 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Tue, 21 Jan 2020 08:05:10 +0100 Subject: ARM: dts: exynos: Add GPU thermal zone cooling maps for Odroid XU3/XU4/HC1 Add trip points and cooling maps for GPU thermal zone for Odroid XU3/XU4/HC1 boards. Trip points are based on the CPU thermal zone for the those boards.
