[PATCH 3/6] ARM: dts: sun6i: hummingbird: Use axp221.dtsi for axp221 regulators

Chen-Yu Tsai wens at csie.org
Fri Aug 28 02:54:36 PDT 2015


Now that we have axp221.dtsi describing common axp22x hardware, use
it and reference the nodes instead of declaring the whole tree.

Also add regulator reference for cpu0 supply.
