dt-bindings: net: dsa: mediatek,mt7530: add econet,en7528-switch
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.
