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,mt7622-audsys", "syscon"
	- "mediatek,mt7623-audsys", "mediatek,mt2701-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 {
			...
		};
	};
