   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" or "allwinner,sun8i-a23-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
