The SPI chipselects are assumed to be active low in the current binding, so when we want to use GPIO descriptors and handle the active low/high semantics in gpiolib, we need a special parsing quirk to deal with this.
This stuff is *incredibly* fragile, are we sure this isn't manifiesting in later kernels as a result of some other fix or cleanup exposing issues and won't break without that fixup? I loose track of all the GPIO stuff.
