From ec51ec401be08a6216f9a29249f733fcd0e74a17 Mon Sep 17 00:00:00 2001 From: Timo Sigurdsson Date: Tue, 4 Aug 2015 23:08:01 +0200 Subject: [PATCH] ARM: dts: sunxi: Raise minimum CPU voltage for sun7i-a20 to meet SoC specifications commit eaeef1ad9b6ea6df1d1220c254d9563da60cb9d1 upstream. sun7i-a20.dtsi contains a cpufreq operating point at 0.9 volts. The minimum CPU voltage for the Allwinner A20 SoC, however, is 1.0 volts. Thus, raise the voltage for the lowest operating point to 1.0 volts in order to stay within the SoC specifications. It is an undervolted setting that isn't stable across all SoCs and boards out there.
