| This binding provides MEC172x board gpio power rails resources to |
| build and run samples/drives/espi in Zephyr. |
| GPIOs required before performing a eSPI host-slave handshake |

| required: true |
| description: | |
| Board GPIO output used to notify eSPI master to ackwnowledge |
| power has stabilized and bare minimum initialization in eSPI slave |
| is complete so eSPI master can proceed with eSPI handshake. |
