| Mapping table between Wake-Up Input (WUI) and 8 IOs belong to this device. |
| Please notice not all IOs connect to WUIs. |
| In this case, it will be presented by wui_none. |
| |
| For example the WUI mapping on NPCX7 GPIO8 would be |
| wui-maps = <&wui_io80 &wui_io81 &wui_io82 &wui_io83 |
| &wui_none &wui_none &wui_io86 &wui_io87>; |

| Mapping table between Low-Voltage controllers and 8 IOs belong to |
| this device. Please notice not all IOs support Low-Voltage detection. |
| In this case, it will be presented by lvol_none. |
| |
| For example the LVOL mapping on NPCX7 GPIOC would be |
| lvol-maps = <&lvol_none &lvol_ioc1 &lvol_ioc2 &lvol_none |
| &lvol_none &lvol_ioc5 &lvol_ioc6 &lvol_ioc7>; |
