Maybe move the dtsi patch to the 3rd or 4th patch in the series?
Things won't work super well without patch #3, right?

Also: do you want to add a 5th patch in the series that enables the
ports like <https://chromium-review.googlesource.com/#/c/210066/>

You included the snps,dwc2 (at my request) here.  ...but you didn't
add it to the bindings (patch #1).  You should probably add it to the
bindings in the next version unless someone else thinks it shouldn't
be here.

Please sort by base address.  ...and if Heiko Acks my EHCI device tree
patches maybe rebase atop my patches to avoid merge conflicts?
