| 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. |
