Thanks for the clarification!

Given the children would in fact depend on the parent's clock being enabled, I wonder if just removing 'simple-mfd' from the compatible list would do the trick?

Dropping simple-mfd would be a requirement in such case, but not sufficient. Please send complete bindings, so with the children. Best regards, Krzysztof
