I'd like to point out that megi (the author of that site/kernel) refuses to upstream the improvements to the mainline linux tree, which is why it's still impossible to boot the PinePhone with a kernel.org kernel and have things working. This is not even just an issue for the PinePhone but all other Allwinner A64 based devices hit the same issues and now have to pick patches from that kernel.

The second megi decides the PinePhone or the A64 isn't interesting anymore (since the new one is Rockchip rk3399) that whole tree maintainership will collapse.
