Cc: netdev <netdev@...r.kernel.org>, Andrew Lunn <andrew@...n.ch>
Subject: [PATCH RFC 18/28] dsa: Add platform device support to Marvell switches
Allow Marvell switches to be platform devices, which probe and then
register with the DSA framework, as component slaves.
Signed-off-by: Andrew Lunn <andrew@...n.ch>

+Marvell DSA Switch Device Tree Bindings
+---------------------------------------
+
+Required properties:
+- compatible : Should be one of "marvell,mv88e6123",
+ "marvell,mv88e6131", "marvell,mv88e6171",
+ "marvell,mv88e6352" or "marvell,mv88e6060"
+- mii-bus : phandle to MII bus the switch is on
+- addr : Address on the MII bus for the switch
+
+Example:
+
+ switchdev0: switchdev0 {
+ compatible = "marvell,mv88e6352";
+ mii-bus = <&mdio_mux_1>;
+ addr = <0>;
+ };
