The churn will happen one way or another. the only question is whether
it happens in drivers/gpio or arch/arm/*.
Grant, what's your feeling here. How much ugliness are you willing to
tolerate in a bulk move to drivers/gpio. At least for OMAP, I am
personally be working on the cleanup/move so I can work either way,
although I know Tony has an obvious preference for moving it to
The OMAP driver is already using gpiolib. The main ugliness in the OMAP
driver is the awful ifdeffery used to handle the differences across the
various SoCs in the OMAP family. I've already got most of that cleaned
