   * aspeed,ast2400-rtc for the ast2400

   * aspeed,ast2500-rtc for the ast2500

   * aspeed,ast2600-rtc for the ast2600



 - reg: physical base address of the controller and length of memory mapped

   region



 - interrupts: The interrupt number



Example:



   rtc@1e781000 {

           compatible = "aspeed,ast2400-rtc";
