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.
