But I don't know how to specify them in the .dts file .

Hi,=20

For detail please look at ePAPR specification.

Say i2c interrupt number is 21 then you can try
"interrupts =3D <21 8>;" in device tree.

Thanks

Please read the FSL MPIC binding.  For internal interrupts, you need to
add 16 to the number in the manual.

This looks ok to me, I hope you provides proper reg, interrupt number, pola=
rity and sense (as per you mpc9247 specification)?
