This platform does not have ACPI so I don't understand how It should also support unconditionally registering devices, if it no longer does so that's a regression in the framework which should be fixed. Looking at mfd_add_devices() I can't see an issue though, both ACPI and DT information is optional - the entire DT section in mfd_add_device() will be skipped if no of_compatible is specified in the cell. Are you *sure* that the regulator driver isn't running?
