1	* Allwinner PRCM (Power/Reset/Clock Management) Multi-Functional Device
2	
3	PRCM is an MFD device exposing several Power Management related devices
4	(like clks and reset controllers).
5	
6	Required properties:
7	 - compatible: "allwinner,sun6i-a31-prcm"
8	 - reg: The PRCM registers range
9	
10	The prcm node may contain several subdevices definitions:
11	 - see Documentation/devicetree/clk/sunxi.txt for clock devices
12	 - see Documentation/devicetree/reset/allwinner,sunxi-clock-reset.txt for reset
13	   controller devices
