 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.
