Hi Arnd You can simply this. DSA has never as far as i remember used an interrupt passed via platform data. Two boards do seem to pass an interrupt via a GPIO line, but it has never been used. So if you want, you could strip all this interrupt code out. There might be some patches coming soon which does add interrupt support to DSA, but it will only be via device tree, since i don't have a platform which is capable of using platform data for DSA.

As of commit 5be9fc23cdb4 ("ARM: orion5x: fix legacy orion5x IRQ numbers"), IRQ zero is no longer a valid interrupt on Orion5x, so we can use the normal convention of using '0' to indicate an invalid interrupt, rather than the deprecated NO_IRQ constant My first approach was to pass a pointer to the resource into orion_ge00_switch_init(), but it seemed to just add complexity for no good.
