Now most of ARM machines has the alsmot same __clk_get/put() macro
So place it at the arch/arm/include/asm/clkdev.h and remove the reduntant header files
But some machines don't have the same form as above. It can use the machince specific clkdev file by HAVE_MACH_CLKDEV config
Now there are only 3 caese.
1) define the clk structure with clkdev macro => Need to move clk structure to proper header file
arch/arm/mach-versatile/include/mach/clkdev.h
arch/arm/mach-realview/include/mach/clkdev.h
arch/arm/mach-vexpress/include/mach/clkdev.h
arch/arm/mach-integrator/include/mach/clkdev.h
2) export the __clk_get/put function at clock.c
arch/arm/mach-shmobile/include/mach/clkdev.h
3) demuxing the clk source
arch/arm/mach-u300/include/mach/clkdev.h

If an ARM system has multiple cpus in the same socket and the
kernel is booted with maxcpus=1, secondary cpus are possible but
not present due to how platform_smp_prepare_cpus() is called.
Since most typical ARM processors don't actually support physical
hotplug, initialize the present map to be equal to the possible
map in generic ARM SMP code. Also, always call
platform_smp_prepare_cpus() as long as max_cpus is non-zero (0
means no SMP) to allow platform code to do any SMP setup.
After applying this patch it's possible to boot an ARM system
with maxcpus=1 on the command line and then hotplug in secondary
cpus via sysfs. This is more in line with how x86 does things.

The ux500 machine was actually defining platform data for the
staging driver ste_rmi4, which is not OK. Let us instead define
some __weak platform data in the machine so that the staging
driver can override it at compile-time and we can thus have the

To be able to relocate the .bss section at run time independently from

be marked static unless they're also const.
Let's remove the static qualifier from current offenders, or turn them

Add support for dynamic detection of the UIB used (at the cost of one i2c error
on the lesser-used UIB) and also provide an override via a command line
parameter if needed.

Try to make the regulators a little bit more useful by adding some
of the most basic consumers we're going to have in the end.

This applies errata fix 753970 for all ux500 platforms. All
current ASICs suffer from this. If the problem is resolved in
later ASICs, the errata selection can be pushed down to other
Kconfig options.

The current code support of dummy timers in absence of local
timer is compile time. This is an attempt to convert it to runtime
so that on few SOC version if the local timers aren't supported
kernel can switch to dummy timers. OMAP4430 ES1.0 does suffer from
this limitation.
This patch should not have any functional impact on affected
files.

DB8500 has irqs from two cores ORed into one. Implement a
workaround to handle this by bouncing the interrupt by setting
the affinity to the other core when the interrupt appears to
be spurious on the current core.
