From 1d2f14117aa7773efff50f832b85fc7779e586e0 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Tue, 24 Jan 2023 12:39:08 +0100 Subject: [PATCH] arm64: dts: amlogic: meson-sm1-odroid-hc4: fix active fan thermal trip Add an active trip tied to the on-board fan cooling device, which is better than describing it along the passive cooling maps.
