Subject[RFC][PATCH 0/5 v2] Fixes and workarounds for dwc2 on HiKey board
Date
I just wanted to re-send my current queue of patches for dwc2
controller on the HiKey board, as my last patchset ended up
colliding with a number of changes that landed in the 4.10-rc
merge window.

I've fixed things up and validated these against HiKey. I also
made a small change to one of the patches as suggested by Vardan.

This does exclude my patchset[1] to add extcon support to dwc2,
which John Youn suspects a pending rework of the dwc2 fifo init
logic might make unnecssary (however, no such changes appeared
to have landed in 4.10-rc, so I'm still using that patchset in
my testing).

I'm also out for the holidays after today, and while I suspect
others are likely going to be out as well, I figured I'd send
these out for a chance at review, rather then sit on them for
two weeks. I'll resend after the new year addressing any
feedback I do get though.

Feedback would be greatly appreciated!

thanks
-john
