This series includes usb controller and phy binding updates
for SC7280 SoC and DT chnages for SC7280 SoC and SC7280 IDP board.
changes in v2:
Dropped dt bindings patches as they are already merged in linux-next.
Addressed comments from Matthias in v1.

It looks like this was here:
https://lore.kernel.org/r/1619112931-2144-1-git-send-email-sanm@codeaurora.org/
...which I guess is a "cover letter", though it's not really formatted
properly (it should usually be listed as "patch 0" in the series) and
also cover letters are discouraged for singleton patches like this.
Also: even when history is added to a cover letter it's usually
friendly to reviewers to also include it after-the-cut in your patch.
