Hi!

The Meson GX watchdog also works on Meson GXBB, so the only modification required is to add the corresponding "compatible" line in sys/arch/arm/amlogic/mesongx_wdt.c:

static const struct device_compatible_entry compat_data[] = {
    { .compat = "amlogic,meson-gx-wdt" },
    { .compat = "amlogic,meson-gxbb-wdt" }, // <= ADD THIS LINE AND REBUILD KERNEL
    DEVICE_COMPAT_EOL
};

When the watchdog triggers, it performs a hardware reset, so the next boot takes a long time because file systems were not cleanly unmounted. That said, if a watchdog triggers, there's probably worse than that to sort out. :)
