I will very strongly disagree here ;-) . Similar to the power-domains being part of the pmu, the io-domains are part of their individual GRFs. So if you want it really clean and tidy the way to go foward will be the attached patches. Compile-tested only. Other things like the usbphy control should move there as well in the long run. But that's not immediate necessary. Heiko -------------- next part -------------- A non-text attachment was scrubbed...
