To skip the introduction of a new binding, rework the driver to address the secondary CPU port as primary and drop any reference of hardcoded port. With configuration of mac06 exchange, just skip the definition of port0 and define the CPU port as a secondary. The driver will autoconfigure the switch to use that as the primary CPU port.

Drop the current delay scan function and move it to the sgmii parser function to generalize and implicitly add support for secondary CPU port set to rgmii-id.

To declare the internal mdio-bus configuration, declare an MDIO node in + the switch node and declare the phandle for the port, referencing the internal + PHY it is connected to. In this config, an internal mdio-bus is registered and + the MDIO master is used for communication. Mixed external and internal + mdio-bus configurations are not supported by the hardware. + +properties: + compatible: + oneOf: + - enum: + - qca,qca8327 + - qca,qca8328 + - qca,qca8334 + - qca,qca8337 + description: | + qca,qca8328: referenced as AR8328(N)-AK1(A/B) QFN 176 pin package + qca,qca8327: referenced as AR8327(N)-AL1A DR-QFN 148 pin package + qca,qca8334: referenced as QCA8334-AL3C QFN 88 pin package + qca,qca8337: referenced as QCA8337N-AL3(B/C) DR-QFN 148 pin package + + reg: + maxItems: 1 + + reset-gpios: + description: + GPIO to be used to reset the whole device + maxItems: 1 + + qca,ignore-power-on-sel: + $ref: /schemas/types.yaml#/definitions/flag + description: + Ignore power-on pin strapping to configure LED open-drain or EEPROM + presence.
