[PATCH 0/5 v2] Fixes and workarounds for dwc2 on HiKey board

[John Stultz]

Hope everyone had a happy new years!

I just wanted to send out my current queue of patches for dwc2
controller on the HiKey board for consideration for the 4.11
merge window.

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.

Any feedback would be greatly appreciated!

thanks
