51 Without interrupt-names, the first interrupt listed must be the one
52 connected to the INT1 pin, the second (optional) interrupt listed must be
53 the one connected to the INT2 pin (if available). The type should be
54 IRQ_TYPE_EDGE_RISING.

56 BMC156 does not have an INT1 pin, therefore the first interrupt pin is
57 always treated as INT2.
