18 MDIO or SPI.
20 The SMI "Simple Management Interface" is a two-wire protocol using
21 bit-banged GPIO that while it reuses the MDIO lines MCK and MDIO does
22 not use the MDIO protocol. This binding defines how to specify the
23 SMI-based Realtek devices. The realtek-smi driver is a platform driver
26 The MDIO-connected switches use MDIO protocol to access their registers.
27 The realtek-mdio driver is an MDIO driver and it must be inserted inside
28 an MDIO node.
