+      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.
