- The first cell is an interrupt number within
|
||
|
|
0..9 range, for GPIO pin interrupts it is equal
|
||
|
|
to 'nxp,gpio-pin-interrupt' property value of
|
||
|
|
GPIO pin configuration, 8 is for GPIO GROUP0
|
||
|
|
interrupt, 9 is for GPIO GROUP1 interrupt
|

|
- The second cell is used to specify interrupt type
