10 | - reg: physical base address of the controller and length of memory mapped |
| 11 | region. | |
| 12 | - interrupts: Two interrupt numbers to the cpu should be specified. First | |
| f21ccfa0 | 13 | interrupt number is the rtc alarm interrupt and second interrupt number |
| 39ce4084 TA |
14 | is the rtc tick interrupt. The number of cells representing a interrupt |
| 15 | depends on the parent interrupt controller. | |

| 17 | Example: | |
| 18 | ||
| 19 | rtc@10070000 { | |
| 20 | compatible = "samsung,s3c6410-rtc"; | |
| 21 | reg = <0x10070000 0x100>; | |
| 22 | interrupts = <44 0 45 0>; | |
| 23 | }; |
