1MediaTek AUDSYS controller
2============================
3
4The MediaTek AUDSYS controller provides various clocks to the system.
5
6Required Properties:
7
8- compatible: Should be one of:
9	- "mediatek,mt2701-audsys", "syscon"
10	- "mediatek,mt6765-audsys", "syscon"
11	- "mediatek,mt6779-audio", "syscon"
12	- "mediatek,mt7622-audsys", "syscon"
13	- "mediatek,mt7623-audsys", "mediatek,mt2701-audsys", "syscon"
14	- "mediatek,mt8183-audiosys", "syscon"
15	- "mediatek,mt8516-audsys", "syscon"
16- #clock-cells: Must be 1
17
18The AUDSYS controller uses the common clk binding from
19Documentation/devicetree/bindings/clock/clock-bindings.txt
20The available clocks are defined in dt-bindings/clock/mt*-clk.h.

22Required sub-nodes:
23-------
24For common binding part and usage, refer to
25../sonud/mt2701-afe-pcm.txt.

27Example:
28
29	audsys: clock-controller@11220000 {
30		compatible = "mediatek,mt7622-audsys", "syscon";
31		reg = <0 0x11220000 0 0x2000>;
32		#clock-cells = <1>;
33
34		afe: audio-controller {
35			...
36		};
37	};
