Eric, Following on Jebediah's remark last month that max732x didn't support interrupt handling, I gave it a shot and hacked something that is similar to what pca953x does. It would be nice if someone (Jebediah?) could give it a shot, as it's been only compile-tested (need to find some time this WE to solder the chips to a board...). Thanks, M. -- Who you jivin' with that Cosmik Debris?
