+* Clock bindings for Ralink/Mediatek MIPS based SoCs
+
+Required properties:
+ - compatible: must be "ralink,rt2880-clock" and
+     one of the following, to identify SoC series
+        "mediatek,mt7620-clock"   for MT7620
+        "mediatek,mt7628-clock"   for MT7628/MT7688
+        "mediatek,mt7621-clock"   for MT7621
+ - #clock-cells: must be 1
+ - ralink,sysctl: a phandle to a ralink syscon register region
+
+
+Example:
+
+clkctrl: clkctrl {
+	compatible = "mediatek,mt7620-clock", "ralink,rt2880-clock";
+	#clock-cells = <1>;
+
+	ralink,sysctl = <&sysc>;
+};
