+Microsemi Ocelot network Switch
+===============================
+
+The Microsemi Ocelot network switch can be found on Microsemi SoCs (VSC7513,
+VSC7514)
+
+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"
You are not documenting the "ports" subnode(s).Please move the
individual ports definition under a ports subnode, mainly for two reasons:

- it makes it easy at the .dtsi level to have all ports disabled by default

- this makes you strictly conforming to the DSA binding for Ethernet
switches and this is good for consistency (both parsing code and just
representation).
ports and port collide with the OF graph binding. It would be good if 
this moved to ethernet-port(s) or similar.
