establish the multiplication factor (M) applied to the reference clock
frequency.

help
Leave SOC watchdog timer enabled at boot. The specific timeout
and clock configuration of the watchdog at boot is SOC dependent.
Note: if the watchdog timer is enabled at boot, the user will
need to configure the watchdog using z_arm_watchdog_init, as
the SOC requires watchdog configuration before initial expiration
