The interconnect provides are quite generic and should be suitable for all Tegra SoCs, but currently upstream kernel has EMC/MC drivers only for those three generations of Tegra SoCs. For the start only display controllers are getting interconnect API support, others could be supported later on. The display controllers have the biggest demand for interconnect API right now because dynamic memory frequency scaling can't be done safely without taking into account bandwidth requirement from the displays.
