| Simple monitorig power domain |
| |
| This power domain monitors the state of a GPIO pin to detect whether a power |
| rail is on/off. Therefore, performing resume/suspend on power domain won't |
| change physical state of power rails and that action won't be triggered on |
| child nodes. Additionally, due to the asynchronous nature of monitoring, a |
| pending transaction won't be interrupted by power state change. |
