I guess this is the standard approach & can be a starting point for
future use cases.

If you still insist on string based then can you please elaborate on it.
Is the events attribute is expected to print string of space separated
events like
for REGULATOR_EVENT_ENABLE -> ENABLE
And even multiple events like: 'UNDER_VOLTAGE REGULATION_OUT'

Let me know your thoughts.
