| * Allwinner PRCM (Power/Reset/Clock Management) Multi-Functional Device |
| |
| PRCM is an MFD device exposing several Power Management related devices |
| (like clks and reset controllers). |
| |
| Required properties: |
| - compatible: "allwinner,sun6i-a31-prcm" or "allwinner,sun8i-a23-prcm" |
| - reg: The PRCM registers range |
| |
| The prcm node may contain several subdevices definitions: |
| - see Documentation/devicetree/clk/sunxi.txt for clock devices |
| - see Documentation/devicetree/reset/allwinner,sunxi-clock-reset.txt for reset |
| controller devices |
| |
| |
| Example: |
| |
| prcm: prcm@1f01400 { |
| compatible = "allwinner,sun6i-a31-prcm"; |
| reg = <0x01f01400 0x200>; |
| |
| /* Put subdevices here */ |
