| 31 | help |
| 32 | Enable driver model for watchdog timer. At the moment the API |
| 33 | is very simple and only supports four operations: |
| 34 | start, restart, stop and reset (expire immediately). |
| 35 | What exactly happens when the timer expires is up to a particular |
| 36 | device/driver. |

| 43 | can be probed and supports all of the methods of WDT, but does not |
| 44 | really do anything. |

| 51 | Select this to enable watchdog timer for Aspeed ast2500/ast2400 devices. |
| 52 | The watchdog timer is stopped when initialized. It performs reset, either |
| 53 | full SoC reset or CPU or just some peripherals, based on the flags. |
| 54 | It currently does not support Boot Flash Addressing Mode Detection or |
| 55 | Second Boot. |
