I'm curious, if the 'reg-names' is a required property, as it is here, does this still break the ABI? Tomi

Yes, the order is part of the ABI. Sometimes we just give up with multiple optional entries or inherited any order allowed, but here there is no reason. Just add 'common1' to the end. Rob

The DSS IP on the ti-am65x soc supports an additional register space, named "common1". Further. the IP services a maximum number of 2 interrupts. Add the missing register space "common1" and the additional interrupt.
