The Meson8m2 SoC is an updated version of the Meson8 SoC. Some of the peripherals are shared with Meson8b (for example the watchdog registers and the internal temperature sensor calibration procedure). Meson8m2 also seems to include the same Gigabit MAC register layout as Meson8b.
The registers in the Amlogic dwmac "glue" seem identical between Meson8b and Meson8m2. Manual testing seems to confirm this. To be extra-safe a new compatible string is added because there's no (public) documentation on the Meson8m2 SoC. This will allow us to implement any SoC-specific variations later on (if needed).
