Al, in the future, please add a description of your changes since the
last revision here, after the --- line. It makes it much easier to
review patch revisions.

Ok, Sergei's comment was addressed.

Also addressed.

You didn't take Sergei's suggestion to change this to usb-xhci-platform.
That's not specific to the IP, so it doesn't violate the DT rules, but
it also lets people know which subsystem xHCI belongs to.
Did you have a strong reason to keep it as xhci-platform, rather than
changing it to usb-xhci-platform?
Sergei, Felipe, do you have a strong preference on this name? Or should
I take the patch as is?

You did add a space here, like Sergei asked.
