      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.
