+Binding for Qualcomm Atheros AR7xxx/AR9XXX PLL controller
+
+The PPL controller provides the 3 main clocks of the SoC: CPU, DDR and AHB.
+
+Required Properties:
+- compatible: has to be "qca,<soctype>-cpu-intc" and one of the following
+ fallback:
+ - "qca,ar7100-pll"
+ - "qca,ar7240-pll"
+ - "qca,ar9130-pll"
+ - "qca,ar9330-pll"
+ - "qca,ar9340-pll"
+ - "qca,ar9550-pll"
+- reg: Base address and size of the controllers memory area
+- clock-names: Name of the input clock, has to be "ref"
+- clock: phandle of the external reference clock
+- #clock-cells: has to be one
+
+Optional properties:
+- clock-output-names: should be "cpu", "ddr", "ahb"
+
+Example:
+
+ pll-controller@18050000 {
+ compatible = "qca,ar9132-ppl", "qca,ar9130-pll";
+ reg = <0x18050000 0x20>;
+
+ clock-names = "ref";
+ clocks = <&extosc>;
+
+ #clock-cells = <1>;
+ clock-output-names = "cpu", "ddr", "ahb";
+ };
