[PATCH RFC v2 00/16] ARM: provide common arch init for DT clocks

[sebastian.hesselbarth@gmail.com (Sebastian Hesselbarth)]

This RFC converts arch/arm to provide a common arch 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 ARM time_init(), we can remove all
mach-specific .init_time hooks that basically called of_clk_init before
starting timers.

Based on the previous version, this one now includes patches provided by
Stephen Warren for mach-tegra and Soren Brinkmann for mach-zynq.

With mach-tegra now requiring clocks as late as the other machs, the
patch to protect of_clk_init() from being called twice, has been dropped.

The RFCv2 is based on next-20130827 and has been compile tested for
multi_v7_defconfig and mach-dove. All single patches have also been sent
to the respective maintainers and corresponding mailing lists.

Before going for a real patch set after v3.11 drops, I prefer to have
Tested-by or Acked-by for at least mach-imx, mach-mxs, mach-sti, and
mach-vexpress. Others are trivial, prepared by maintainers (mach-tegra
and mach-zynq), or have already been Acked-by (mach-highbank).

Also, I'd like to know if the patches should be grouped by mach- or
rather been split into mach- preparation and .init_time removal.

Sebastian Hesselbarth (14):
  ARM: call clk_of_init from time_init
  ARM: dove: remove custom .init_time hook
  ARM: exynos: remove custom .init_time hook
