I looked again into patches 1-8 and if there are concerns: - nomadik can be dropped as it still has custom .init_time. - prima2 and sunxi are quite straight forward but also have custom .init_time that protect them from the arch-wide call. - socfpga needs some new custom .init_time then. - vt8500 is a little bit more changes but has .init_time call to clocksource_of_init alone.
