Subject: [PATCH] ARM: dts: sunxi: Raise minimum CPU voltage for sun7i-a20 to a level all boards can supply
Date: Sun, 2 Aug 2015 21:23:06 +0200 [thread overview]
Message-ID: <1438543386-7253-1-git-send-email-public_timo.s@silentcreek.de> (raw)
sun7i-a20.dtsi contains an cpufreq operating point at 0.9 volts. Most A20 boards
(or all?), however, do not allow the voltage to go below 1.0V. Thus, raise the
voltage for the lowest operating point to 1.0V so all boards can actually use
it.
