  1. * Allwinner PRCM (Power/Reset/Clock Management) Multi-Functional Device
  2. PRCM is an MFD device exposing several Power Management related devices
  3. (like clks and reset controllers).
  4. Required properties:
  5. - compatible: "allwinner,sun6i-a31-prcm" or "allwinner,sun8i-a23-prcm"
  6. - reg: The PRCM registers range
  7. The prcm node may contain several subdevices definitions:
  8. - see Documentation/devicetree/clk/sunxi.txt for clock devices
  9. - see Documentation/devicetree/reset/allwinner,sunxi-clock-reset.txt for reset
  10. controller devices
  11. Example:
  12. prcm: prcm@01f01400 {
  13. compatible = "allwinner,sun6i-a31-prcm";
  14. reg = <0x01f01400 0x200>;
  15. /* Put subdevices here */
  16. ar100: ar100_clk {
  17. compatible = "allwinner,sun6i-a31-ar100-clk";
  18. #clock-cells = <0>;
  19. clocks = <&osc32k>, <&osc24M>, <&pll6>, <&pll6>;
  20. };
  21. ahb0: ahb0_clk {
  22. compatible = "fixed-factor-clock";
  23. #clock-cells = <0>;
