@@ -6,17 +6,25 @@ The MediaTek AUDSYS controller provides various clocks to the system.
 Required Properties:
 
 - compatible: Should be one of:
-	- "mediatek,mt7622-audsys", "syscon"
+	- "mediatek,mt2701-audsys", "syscon", "simple-mfd"
+	- "mediatek,mt7622-audsys", "syscon", "simple-mfd"
 - #clock-cells: Must be 1
 
 The AUDSYS controller uses the common clk binding from
 Documentation/devicetree/bindings/clock/clock-bindings.txt
 The available clocks are defined in dt-bindings/clock/mt*-clk.h.
 
+See ../sound/mt2701-afe-pcm.txt for details about required subnode.

 Example:
 
-audsys: audsys@11220000 {
-	compatible = "mediatek,mt7622-audsys", "syscon";
-	reg = <0 0x11220000 0 0x1000>;
-	#clock-cells = <1>;
