Yes. In fact, as the description suggests, this also applies retroactively to
H3 and A64, which were added in the following commits:

4.9  732e35da7b4a ("dt: bindings: add bindings for Allwinner A64 usb phy")
4.5  626a630e003c ("phy-sun4i-usb: Add support for the host usb-phys found
                    on the H3 SoC")

Though this was missed at the time the binding was added.
