Martin/Vinayak: Wanted to nudge either of you to see if you had any
further feedback or objections on this patchset? Its been a long slow
slog for this patch-set and getting it upstream will make the HiKey960
board much more useful for testing mainline kernels.

If you don't have objections, would you consider merging the scsi
driver and Acked dt-bindings via the scsi tree?   Including the dts
changes too if Wei Xu (now cc'ed) acks it, would be helpful as well
(but that can go separately later if necessary).

The defconfig change isn't as important, so I suspect can be re-pushed
through the ARM maintainers later.

thanks
