   49       Without interrupt-names, the first interrupt listed must be the one
   50       connected to the INT1 pin, the second (optional) interrupt listed must be
   51       the one connected to the INT2 pin (if available). The type should be
   52       IRQ_TYPE_EDGE_RISING.
   53 
   54       BMC156 does not have an INT1 pin, therefore the first interrupt pin is
   55       always treated as INT2.
