+Binding for Mediatek MT7621 PLL controller
+
+The PLL controller provides the 2 main clocks of the SoC: CPU and BUS.
+
+Required Properties:
+- compatible: has to be "mediatek,mt7621-pll"
+- #clock-cells: has to be one
+
+Optional properties:
+- clock-output-names: should be "cpu", "bus"
+
+Example:
+ pll {
+ compatible = "mediatek,mt7621-pll", "syscon";
+
+ #clock-cells = <1>;
+ clock-output-names = "cpu", "bus";
+ };
