Well to backup TS it's not totally their fault... It's a Maxim/Dallas
problem, and you'll find it with a lot of their SPI devices. There's a
appnote on their site on how to make them play nice by buffering the
lines but it's sure a pain sometimes, especially if you want to mix a
number of Dallas devices with "real" SPI devices.
