From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Mon, 11 Jan 2021 15:53:55 +0100 Subject: arm64: dts: meson: g12b: odroid-n2: add fan as cooling device Add the GPIO fan as a cooling device for the CPU thermal zone. Since we have only full fan speed available with this, set the tripping point to 30 degrees Celsius.
