| Overview |
| ******** |
| |
| An HWSPINLOCK device is a peripheral used to protect shared resources across clusters in the system. |
| Each HWSPINLOCK instance is providing one or more spinlocks. The api is similar to regular zephyr spinlocks. |

| |
| Because we also want to protect the spinlock resource to be used by multiple cores in the same |
| cluster, each HWSPINLOCK device include a regular zephyr spinlock, and use it to lock the access to |
| HWSPINLOCK hardware. |
