dt-bindings: convert the binding document for mediatek PERICFG to yaml 



Convert the DT binding .txt file for MediaTek's peripheral configuration
controller to YAML. There's one special case where the compatible has
three positions. Otherwise, it's a pretty normal syscon.

Mediatek pericfg controller

===========================



The Mediatek pericfg controller provides various clocks and reset

outputs to the system.



Required Properties:



- compatible: Should be one of:

	- "mediatek,mt2701-pericfg", "syscon"

	- "mediatek,mt2712-pericfg", "syscon"

	- "mediatek,mt7622-pericfg", "syscon"

	- "mediatek,mt7623-pericfg", "mediatek,mt2701-pericfg", "syscon"

	- "mediatek,mt7629-pericfg", "syscon"

	- "mediatek,mt8135-pericfg", "syscon"

	- "mediatek,mt8173-pericfg", "syscon"

	- "mediatek,mt8183-pericfg", "syscon"

- #clock-cells: Must be 1

- #reset-cells: Must be 1



The pericfg 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.

Also it uses the common reset controller binding from

Documentation/devicetree/bindings/reset/reset.txt.

The available reset outputs are defined in

dt-bindings/reset/mt*-resets.h



Example:



pericfg: power-controller@10003000 {

	compatible = "mediatek,mt8173-pericfg", "syscon";

	reg = <0 0x10003000 0 0x1000>;

	#clock-cells = <1>;

	#reset-cells = <1>;

};
