Just because you see patches, doesn't mean they've been accepted for
upstream inclusion, just for review.

We support the vast majority when ever it lands in an upstream
mainline kernel. So in the case of rawhide that's usually with in a
day or two of Linus landing the pull request. In the case of a stable
Fedora release the kernel team normally push a new kernel to the
stable releases around the .2 stable release but that varies a little
with each kernel cycle.

With a quick look it looks like only some of the bits for the MMC
(clocking/regulators) on sun8i/a83/cubie 5 have landed upstream in 4.7
so it's still not in a usable state so it would be 4.8 at the
earliest.
