The EcoNet EN7528 MIPS SoC integrates an MT7530 Gigabit switch, memory-mapped in the SoC register space like the built-in switches of the MediaTek MT7988 and Airoha EN7581/AN7583 SoCs. Its four user ports are connected to integrated Gigabit PHYs and its CPU port is connected internally to the SoC Ethernet MAC. Those three switches are MT7531-based, whereas the EN7528 has a genuine MT7530 switch core (its chip revision register reads 0x7530). The two generations differ in their register programming - for example the CPU port is selected through the MT7530-style MFC register rather than the MT7531 CFC register - so the EN7528 is not compatible with the existing switch compatibles and cannot fall back to one of them. Add the econet,en7528-switch compatible, with the same constraints as the other built-in switches.
