-MediaTek AUDSYS controller
-============================
-
-The MediaTek AUDSYS controller provides various clocks to the system.
-
-Required Properties:
-
-- compatible: Should be one of:
-	- "mediatek,mt2701-audsys", "syscon"
-	- "mediatek,mt6765-audsys", "syscon"
-	- "mediatek,mt6779-audio", "syscon"
-	- "mediatek,mt7622-audsys", "syscon"
-	- "mediatek,mt7623-audsys", "mediatek,mt2701-audsys", "syscon"
-	- "mediatek,mt8167-audiosys", "syscon"
-	- "mediatek,mt8183-audiosys", "syscon"
-	- "mediatek,mt8192-audsys", "syscon"
-	- "mediatek,mt8516-audsys", "syscon"
-- #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.
-
-Required sub-nodes:
--------
-For common binding part and usage, refer to
-../sonud/mt2701-afe-pcm.txt.
-
-Example:
-
-	audsys: clock-controller@11220000 {
-		compatible = "mediatek,mt7622-audsys", "syscon";
-		reg = <0 0x11220000 0 0x2000>;
-		#clock-cells = <1>;
-
-		afe: audio-controller {
-			...
-		};
-	};
