This is a batch of fixes and improvements for the phy-meson8b-usb2 driver: - convert the existing dt-bindings to json-schema and add a fallback compatible string which is already in existing .dtsi files - differentiate between Meson8 and Meson8m2 using a new compatible string for the latter - simplify the code by using a MMIO regmap - set / unset the IDDQ and ACA enable bits depending on the operating mode (and for the latter also the compatible string) I suggest that all of these are applied to -next because we will need a separate .dts patch (which I already have prepared) to use the new Meson8m2 compatible string in meson8m2.dtsi. Otherwise we will be changing behavior in patch #4, because meson8m2.dtsi currently inherits the Meson8 compatible string. The number of actual Meson8 users is very small (I only know one case), so keeping Meson8m2 working is more important to me (because I know several users with boards that have a Meson8m2 SoC).
