The IP has a configurable number of banks, each of which has its own
interrupt.  If a particular SoC was configured to have six banks then
you need to list six interrupts in the DTS.  Perhaps it would help to
spell that out that relationship explicitly in the documentation
rather than talking about a minimum or maximum number of interrupts?
Also, you may want to mention that interrupts should to be ordered by
bank number.
