Looks good if ibm,current-associativity-domains[min_common_depth] actually denotes the range of possible values, i.e. a value of 2 implies node numbers 0 and 1. PAPR+ says it's the "number of unique values", which isn't how I would specify the property if it's supposed to express a range. But it's probably OK...
