Hi @rusatch - yes, however this is actually even easier to enable now; no patching and custom kernels should be needed   If you build Armbian from the latest top-of-tree for a sunxi device (starting with the 4.17.y kernel), two new DT overlays are provided that you can load via "/boot/armbianEnv.txt" that provide this regulator and will enable higher clock speeds to be used.  The original thread regarding this (with instructions) can be found here:  https://forum.armbian.com/topic/5051-nanopi-ne
