Which interrupts and interrupt-parent to use in spi node

Hi, I am trying to add a new codec to spi@0 of spi@3210000. I learnt that I need to add a ‘interrupts’ and ‘interrupt-parent’ property to it. I see a lot of nodes with the ‘interrupt-controller’ property. So how do I know which will be the interrupt-parent?

Thanks.

Suppose it doesn’t matter with SPI. You may need maybe GPIO pin connect to codec interrupt pin and have define the “interrupt-parents” and “interrupts” in the codec scope.
