However, the switch address space is mapped into the SoCs memory space rather than being connected via MDIO. Using MMIO simplifies register access and also removes the need for a bus lock, and for that reason also makes interrupt handling more light-weight. Note that this is different from previous SoCs like MT7621 and MT7623N which also came with an integrated MT7530-like switch which yet had to be accessed via MDIO.
