0049 Without interrupt-names, the first interrupt listed must be the one
0050 connected to the INT1 pin, the second (optional) interrupt listed must be
0051 the one connected to the INT2 pin (if available). The type should be
0052 IRQ_TYPE_EDGE_RISING.
0053
0054 BMC156 does not have an INT1 pin, therefore the first interrupt pin is
0055 always treated as INT2.
