What's the difference in these SoCs? You should probably have the part#'s in the compatible string.
+
+Required properties:
+- compatible: Should be "mscc,ocelot-switch"
+- reg: Must contain an (offset, length) pair of the register set for each
+ entry in reg-names.
+- reg-names: Must include the following entries:
+ - "sys"
+ - "rew"
+ - "qs"
+ - "hsio"
+ - "qsys"
+ - "ana"
+ - "portX" with X from 0 to the number of last port index available on that
+ switch
+- interrupts: Should contain the switch interrupts for frame extraction and
+ frame injection
+- interrupt-names: should contain the interrupt names: "xtr", "inj"
+
+Example:
+
+ switch@1010000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "mscc,ocelot-switch";
+ reg = <0x1010000 0x10000>,
+ <0x1030000 0x10000>,
+ <0x1080000 0x100>,
+ <0x10d0000 0x10000>,
+ <0x11e0000 0x100>,
+ <0x11f0000 0x100>,
+ <0x1200000 0x100>,
+ <0x1210000 0x100>,
+ <0x1220000 0x100>,
+ <0x1230000 0x100>,
+ <0x1240000 0x100>,
+ <0x1250000 0x100>,

+ reg-names = "sys", "rew", "qs", "hsio", "port0",
+ "port1", "port2", "port3", "port4", "port5",
+ "port6", "port7", "port8", "port9", "port10",

+ interrupts = <21 22>;
