description: |
  MStar/SigmaStar's Armv7 SoCs that have more than one processor
  have a region of registers that allow setting the boot address
  and a magic number that allows secondary processors to leave
  the loop they are parked in by the boot ROM.

  compatible:
    items:
      - enum:
          - sstar,ssd201-smpctrl # SSD201/SSD202D
      - const: mstar,smpctrl

  reg:
    maxItems: 1

required:
  - compatible
  - reg

additionalProperties: false

examples:

    smpctrl@204000 {
        compatible = "sstar,ssd201-smpctrl", "mstar,smpctrl";
