+Realtek PHY properties.
+
+This document describes properties of Realtek PHYs.
+
+Optional properties:
+- realtek,enable-ssc Enable Spread Spectrum Clocking (SSC) on this port.
+ SSC is only available on some Realtek PHYs (e.g.
+ RTL8211E).
+
+Example:
+
+mdio0 {
+ compatible = "snps,dwmac-mdio";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ ethphy: ethernet-phy@1 {
+ reg = <1>;
+ realtek,enable-ssc;
+ };
+};
