Subject: [PATCH 1/2] arm64: dts: renesas: salvator-common: Add cpu-supply property to a57_0 node
Date: Fri, 26 Mar 2021 11:50:08 +0100	[thread overview]
Message-ID: <20210326105009.1574424-2-geert+renesas@glider.be> (raw)
In-Reply-To: <20210326105009.1574424-1-geert+renesas@glider.be>

From: Dien Pham <dien.pham.ry@renesas.com>

Add the cpu-supply property to the a57_0 node, so Dynamic Voltage and
Frequency Scaling (DVFS) can change the CPU core voltage.
