I don't think we need a dependency, the #ifdef checks in there were needed only to make the driver smaller if OF is disabled and it should still build fine if someone tries to compile it for CONFIG_COMPILE_TEST without CONFIG_OF. If we remove the platform ID, we can however also remove the spacc_is_compatible() function and just call of_device_is_compatible() in its place. Arnd
