This completes the ARM RealView PB1176 and PB11MPCore device trees, and moves the Versatile to use power/reset. The idea is to keep working on this cleanup branch and send additional patches on top of this one as the prerequisites are merged into the MTD and FBDEV subsystems. So please create a special versatile cleanup branch (or suggest another approach). As it happens, board files and device trees need to change at the same time to make logical sense, especially for Versatile where auxdata is replaced with DT entries, such as when reset is moved in the last patch in this set. The MTD and CLCD changes will share this characteristic."
