| description: | |
| Without interrupt-names, the first interrupt listed must be the one |
| connected to the INT1 pin, the second (optional) interrupt listed must be |
| the one connected to the INT2 pin (if available). The type should be |
| IRQ_TYPE_EDGE_RISING. |
| |
| BMC156 does not have an INT1 pin, therefore the first interrupt pin is |
| always treated as INT2. |
