Subject: [PATCH v5 2/9] arm64: dts: allwinner: h6: Add thermal trip points/cooling map
Date: Mon, 20 Apr 2020 15:00:14 +0200 [thread overview]
Message-ID: <20200420130021.3841-3-peron.clem@gmail.com> (raw)
In-Reply-To: <20200420130021.3841-1-peron.clem@gmail.com>
From: Ondrej Jirman <megous@megous.com>
This enables passive cooling by down-regulating CPU voltage
and frequency.
