+ Enables driver-side support for ADC analog watchdog events on
STM32H5:
+ - ISR enqueues AWD events in a small ring buffer
+ - Optional POSIX signal (pid/signo) can be sent from deferred
context
+ If disabled, the driver will not compile in the event/notify
path.
+
+ This option selects the kernel work queue so the driver can
post work
+ from interrupt context without linking errors.
