 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
+- compatible: has to be "qca,<soctype>-pll" and one of the following
   fallbacks:
   - "qca,ar7100-pll"
   - "qca,ar7240-pll"
···
 
 Example:
 
-	memory-controller@18050000 {
-		compatible = "qca,ar9132-ppl", "qca,ar9130-pll";
+	pll-controller@18050000 {
+		compatible = "qca,ar9132-pll", "qca,ar9130-pll";
 		reg = <0x18050000 0x20>;
 
 		clock-names = "ref";
