You can put the board rate etc in the stdout-patch. Something like:
stdout-path = "serial0:115200n8";
+ gpio-leds {
+ compatible = "gpio-leds";
+ pinctrl-0 = <&pmx_power_led &pmx_power_led_blink &pmx_wan_led>;
+ pinctrl-names = "default";
+
+ led@0 {
+ label = "power:green";Documentation/leds/leds-class.txt says: LED Device Naming ================= Is currently of the form: "devicename:colour:function"
+ dsa@0 {
+ compatible = "marvell,dsa";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ dsa,ethernet = <ðport>;
+ dsa,mii-bus = <&mdio>;
+
+ switch@0 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0 0>; /* MDIO address 0, switch 0 in tree */
+
+ port@0 {
+ reg = <0>;
+ label = "lan3";
+ };
+
+ port@1 {
+ reg = <1>;
+ label = "lan4";
+ };
+
+ port@2 {
+ reg = <2>;
+ label = "wan";
+ };
+
+ port@3 {
+ reg = <3>;
+ label = "cpu";
+ };
+
+ port@5 {
+ reg = <5>;
+ label = "lan1";
+ };
+
+ port@7 {
+ reg = <7>;
+ label = "lan2";
+ };
+ };
+ };
+};This all looks sensible, if a bit mixed up. Lets discuss the switch issue in a different thread.

+ #address-cells = <1>;

+ marvell,function = "gpio";
+ };
+
+ pmx_reset_switch: pmx-reset-switch {
+ marvell,pins = "mpp1";
+ marvell,function = "gpio";
+ };Ah, this is missing from your DSA node. You can then add: reset-gpios = <&gpio0 1 GPIO_ACTIVE_LOW>; inside the switch@0 node.
+ pmx_ge: pmx-ge {
+ marvell,pins = "mpp9", "mpp12", "mpp13", "mpp14", "mpp15",
+ "mpp16", "mpp17", "mpp18", "mpp19";
+ marvell,function = "ge";
+ };
+};This can go into the .dtsi file your previous patch added.

Nice to see the comment.
