However, there are some non-backwards-compatible HW differences, and hence a new DT compatible value must be used to describe the HW. This patch updates the driver to support that new compatible value. That said, the HW differences are only relevant when enabling certain high-performance transfer modes. Since the driver is currently very simple and doesn't enable those modes, we don't actually need to address any of these HW differences in the code yet, hence the simple nature of this patch.
