| 34 | The "loongson,suspend-address" is a deep sleep state (Suspend To |
| 35 | RAM) firmware entry address which was jumped from kernel and it's |
| 36 | value was dependent on specific platform firmware code. In |
| 37 | addition, the PM need according to it to indicate that current |
| 38 | SoC whether support Suspend To RAM. |
