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.
