Merge branch 'clk-of-init-v2_for-3.13' of https://github.com/shesselba/linux-dove into next/cleanup
From Sebastian Hasselbarth:
This is a patch set based on an RFC [1][2] sent earlier to provide
a common arch/arm init for DT clock providers. Currently, the call to
of_clk_init(NULL) to initialize DT clock providers is spread among several
mach-dirs. Since most machs require DT clocks initialized before timers,
no initcall can be used.
By adding of_clk_init(NULL) to arch/arm time_init(), we can remove all
mach-specific .init_time hooks that basically called of_clk_init and
clocksource_of_init.
In contrast to the RFC version, of_clk_init(NULL) is now only called if
no custom .init_time callback is set. This allows some machs to still
call clock init themselves, as not all can be converted now. Therefore,
this patch sets drops conversion of mach-mvebu and mach-zynq. New machs
that were introduced with v3.12-rc1 are also converted, except mach-u300
that requires clocks before irqs.
