Subject: [PATCH 2/2] arm64: dts: renesas: ulcb: Add cpu-supply property to a57_0 node
Date: Fri, 26 Mar 2021 11:50:09 +0100 [thread overview]
Message-ID: <20210326105009.1574424-3-geert+renesas@glider.be> (raw)
In-Reply-To: <20210326105009.1574424-1-geert+renesas@glider.be>
From: Yusuke Goda <yusuke.goda.sx@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.
