Subject: [PATCH 6/6] ARM: dts: sun8i: raise the max voltage of DCDC2 in sun8i reference tablets
Date: Tue, 13 Dec 2016 23:22:52 +0800 [thread overview]
Message-ID: <20161213152252.53749-7-icenowy@aosc.xyz> (raw)
In-Reply-To: <20161213152252.53749-1-icenowy@aosc.xyz>
The "extremity_freq" frequency described in the original FEX files uses
a voltage of 1.46v, which is beyond the current maximum voltage value of
DCDC2 (Cortex-A7 supply) in the sun8i reference tablet DTSI file.
Raise the maximum value to 1.46v.
