@@ -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>;
