With this plus the amount of conditional schema, I think this should be a new schema doc. Doesn't have to have a common schema. You can let the 2nd user of this IP block do that. Though if you have the Synopsys spec, then it would be good to use it and be sure the binding corresponds to it. Rob

Right, I should have properly explained that initially this QP controller has been handled more like another variant of those found in the older SoCs, rather than a totally new one. It doesn't really have anything in common, except that the IP comes from Synopsys, hence it makes sense to also have a dedicated schema. Thanks, Cristian
