Subject: [PATCH 3/3] arm64: allwinner: a64: set CPU regulator for Pine64
Date: Sat, 23 Sep 2017 08:15:31 +0800 [thread overview]
Message-ID: <20170923001531.14285-4-icenowy@aosc.io> (raw)
In-Reply-To: <20170923001531.14285-1-icenowy@aosc.io>
The DCDC2 regulator of the AXP803 PMIC is used for the voltage scaling
of the ARM cores on the A64 SoC.
Add this definition to enable it on Pine64.
