I know Robin has already replied with more detailed info, but just to
close the loop as I'm finally home, applying this patch didn't seem to
help with the IO hangs I'm seeing w/ HiKey960.
If Robins observation is right this should fix the problem for you:
Please could you give this diff a try and let us know whether the problem
persists with your board?
This is actually the exact same change that I ended up with in my
fixes[1], which John has indeed confirmed.
(sorry, it's the thing I was telling you about the other day, but I
neglected to include you on cc you when I sent the patches out the
following morning)
Robin.
