Oops, you're right. The patch didn't apply. Here's a backported version for
the linux-4.1.y tree, tested on top of 4.1.12.

Subject: [PATCH] ARM: dts: sunxi: Raise minimum CPU voltage for sun7i-a20 to
meet SoC specifications
Backport of commit eaeef1ad9b6e ("ARM: dts: sunxi: Raise minimum CPU
voltage for sun7i-a20 to meet SoC specifications") 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.
Fixes: d96b7161916f ("ARM: dts: sun7i: Add cpu clock reference and
operating points to dtsi")
