+ PHY package can be configured in 2 modes:
+ - internal: YT8824 is embedded in the switch, using
+ an internal interface to the MAC.
+ - 10g-qxgmii: YT8824 is a standalone external PHY,
+ connected via 10G QXGMII.
+ $ref: /schemas/types.yaml#/definitions/string
+ enum: [ internal, 10g-qxgmii ]
+
+ reg:
+ description:
+ The absolute MDIO address of the YT8824 shared top extend
+ register block.
+ For internal mode, this is fixed at 9;
+ For external mode, it is the base MDIO address of the four
+ member PHYs plus 4, where base is typically 0x0.
+ Note that this is NOT the reg of the first member PHY.
