Re: [PATCH net-next v2 08/13] dt-bindings: net: dsa: realtek-mdio: document new interface

+Realtek MDIO-based Switches
+==========================
+
+Realtek MDIO-based switches use MDIO protocol as opposed to Realtek
+SMI-based switches. The realtek-mdio driver is an mdio driver and it must
+be inserted inside an mdio node.
+
+Required properties:
+
+- compatible: must be exactly one of (same as realtek-smi):
+      "realtek,rtl8365mb" (4+1 ports)
+      "realtek,rtl8366"               (not supported yet)
+      "realtek,rtl8366rb" (4+1 ports)
+      "realtek,rtl8366s"  (4+1 ports) (not supported yet)
+      "realtek,rtl8367"               (not supported yet)
+      "realtek,rtl8367b"              (not supported yet)
+      "realtek,rtl8368s"  (8 port)    (not supported yet)
+      "realtek,rtl8369"               (not supported yet)
+      "realtek,rtl8370"   (8 port)    (not supported yet)
+
+Required properties:
+- reg: MDIO PHY ID to access the switch
+
+Optional properties:
+- realtek,disable-leds: if the LED drivers are not used in the
+  hardware design this will disable them so they are not turned on
+  and wasting power.
+
+See net/dsa/dsa.txt for a list of additional required and optional properties
+and subnodes of DSA switches.
+
+Optional properties of dsa port:
+
+- realtek,ext-int: defines the external interface number (0, 1, 2). By default, 1.
