| description: |
| ARM 11MP, Cortex-A5 and Cortex-A9 are often associated with a per-core |
| Timer-Watchdog (aka TWD), which provides both a per-cpu local timer |
| and watchdog. |
| |
| The TWD is usually attached to a GIC to deliver its two per-processor |
| interrupts. |
| |

| compatible: |
| enum: |
