Hi I write a kmod driver for bh1750 light sensor with iic (almost wrote). As usual, probe(), attach() and detach(). On attach() it runs TIMEOUT_TASK_INIT for periodically write opecode, read result and place it to sysctl dev.bh1750.N variables. It is all. But I see that some other devices (from /usr/src/sys/dev) uses CONFIG_INTRHOOK(9) on attach() for initialize themselfs. I wonder if I need this too? ...or maybe... when I might need it?
