I've prepared a git tree with the minimal sunxi-mmc support so
that we
can properly get Fedora to run (headless) on Axx boards. You can
find the patch-set here:
https://github.com/jwrdegoede/linux-sunxi/commits/sunxi-mmc
This patch set looks larger then it really is as upstream wants the dts
bits cut into quite small patches.
This basically consists of 3 bits:
1) some sunxi-clk driver changes
2) a new sunxi-mmc.c file
3) dts bindings for the above
Note this only touches sunxi specific files. If I get no objections
the next few days I'm going to squash this all into one big sunxi-mmc
patch and add that to the rawhide kernel builds.
