From f1120f132dbdf2e7f7acf328de55bbdce877d882 Mon Sep 17 00:00:00 2001 Message-Id: In-Reply-To: References: From: Stefan Agner Date: Mon, 11 Jan 2021 15:53:55 +0100 Subject: [PATCH 6/9] arm64: dts: meson: g12b: odroid-n2: add fan as cooling device MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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°C.
