reset. If this setting is enabled, then all clocking will be enabled
to all of the selected peripherals on reset.

bool "Enabled on reset"

---help---
The WDT can be enabled at reset. This is controlled by the WDTAUTO
fuse. The WDT will be set in basic mode, RCSYS is set as source for
CLK_CNT, and PSEL will be set to a value giving Tpsel above 100 ms
(SAM4L)
This setting informs that start-up logic that the watchdog is
enabled.
config WDT_DISABLE_ON_RESET
bool "Disable on reset"
default n
depends on WDT_ENABLED_ON_RESET
---help---
If the WDT can be enabled at reset then this setting may be used to
configure and disable the watchdog timer very early in the boot
sequence.
