This config exists entirely to hide the cpufreq menu from the
kernel configuration unless a platform has selected it. Nothing
is actually built if this config is 'Y' and it just leads to more
patches that add a select under a platform Kconfig so that some
other CPUfreq option can be chosen. Let's remove the option so
that we can always enable CPUfreq drivers on ARM platforms.Acked-by: Viresh Kumar

With arch/arm calling of_clk_init(NULL) from time_init(), we can now
remove custom .init_time hooks.Signed-off-by: Sebastian Hesselbarth
Acked-by: Tony Prisk -
Current vt8500 board init calls of_clk_init() from vtwm_clk_init. To allow
consolidation of DT driven .time_init, move of_clock_init() to a temporary
.time_init callback that will be removed when arch-wide callback is available.
With previous pmc_base parsing helper for vt8500 clock providers, we can also
safely remove the call to vtwm_clk_init() and get rid of some includes.Signed-off-by: Sebastian Hesselbarth

When I tried booting a stih415 Dual core A9 with multi_v7_defconfig, it
failed to boot. The issues seems to be changing by enabling or disabling
VT8550 platform. Having a quick look at dt_compat list, it seems to miss
a NULL terminator, which means of_flat_dt_match will compat check will
cross the boundary of dt_compat and fault at some point , which is what
was happening in my case.Without this patch if we try to boot multi_v7_defconfig you might notice
that some of the platforms might fault if they fall after vt8500 in
machine-desc list. Other platforms which fall before vt8500 in mdesc list
will not fault.Signed-off-by: Srinivas Kandagatla

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

Pull ARM soc multiplatform enablement from Olof Johansson:
"This is a pretty significant branch. It's the introduction of the
first multiplatform support on ARM, and with this (and the later
branch) merged, it is now possible to build one kernel that contains
support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
platforms will be convered over in the next few releases.Two critical last things had to be done for this to be practical and
possible:
* Today each platform has its own include directory under
mach-/include/mach/*, and traditionally that is where a lot
of driver/platform shared definitions have gone, such as platform
data structures. They now need to move out to a common location
instead, and this branch moves a large number of those out to
include/linux/platform_data.
* Each platform used to list the device trees to compile for its
boards in mach-/Makefile.boot.Both of the above changes will mean that there are some merge
conflicts to come (and some to resolve here). It's a one-time move
and once it settles in, we should be good for quite a while. Sorry
for the overhead."Fix conflicts as per Olof.
