| This hidden symbol must be selected by drivers which |
| implement support for a watchdog timer that is enabled |
| by default after system reset. |

| config WDT_DISABLE_AT_BOOT |
| bool "Disable watchdog timers at boot" |
| depends on HAS_WDT_DISABLE_AT_BOOT |
| help |
| Disable watchdog timers during Zephyr system startup. |
| |
| This option has no effect when disabled and only applies to drivers |
| that select HAS_WDT_DISABLE_AT_BOOT. Drivers that do not select |
| HAS_WDT_DISABLE_AT_BOOT must ignore this option. |
| |
| When enabled, all watchdog timer instances enabled in Devicetree must |
| be disabled by their respective drivers during instance initialization. |
| |
| Note that enabling this option may render certain watchdog timers |
| unusable by the application, depending on the hardware implementation |
| (e.g., if the timer cannot be re-enabled after being disabled). |

| help |
| Watchdog emulated with counter device. If counter device supports using |
| zero latency interrupts (ZLI) then expiration callback can be called from |
| that context. This watchdog can be used along hardware watchdog to |
| overcome hardware watchdog limitations, e.g. Nordic devices reset |
| unconditionally at fixed time after hitting watchdog interrupt, leaving |
| no time to print debug information. Watchdog has limitations since it |
| cannot interrupt same or higher priorities so it cannot fully replace |
| hardware based watchdog. |

| Note that actual channel count will be limited to number of channels |
| supported by the counter device which is used for watchdog. |
