this adds a devicetree binding, so you should include devicetree people in
the recipient list:

Rob Herring <robh+dt@...nel.org>
Mark Rutland <mark.rutland@....com>
devicetree@...r.kernel.org

as they should Ack such binding additions.

devicetree compatibles should not contain wildcards, so please name that
"rockchip,rk3228-usb2phy"

here and in the driver as well.
