I am using linux-next, which has this patch applied and I am getting:

smsc911x smsc911x.0: Failed to get supply 'vdd33a': -517
smsc911x smsc911x.0: (unregistered net_device): couldn't get regulators -517
platform smsc911x.0: Driver smsc911x requests probe deferral

Does this work for you on pcm037?

If I select CONFIG_REGULATOR_DUMMY then the the smsc driver is probed
correctly, but if I understand correctly your suggestion was to not
select CONFIG_REGULATOR_DUMMY, right?
