The channels have separate registers and sometimes separate interrupts -- it's simpler to bind to a channel at a time than to parse a list of reg blocks and interrupts. It's also more flexible in case a new chip comes out with more/fewer channels, or if certain channels are not general purpose. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
