See attached files.

These file are .dts file from LSDK 1906 for the LS1088ARDB board.

Find IRQ10 in the fsl-ls1088a-rdb.dts file.

The LS1088ARDB board uses interrupt from the PCF2129.

NXP Linux BSP supports sysfs possibility for GPIO interrupt using. Use this possibility for your application.

Have a great day,
