Okay, I understand that the behaviour should be like the always-on
contrain. But now the behaviour of the core is like my v1 of
"Re-Enable support to disable switch regulators". It's like a 'simulated
off', which wasn't a good solution for you. The difference is, that the
'simulated off' is now made in the core.

Regards,
Marco
