Commit 07e461cd7e73a84f0e3757932b93cc80976fd749
"of: Ensure unique names without sacrificing determinism"
caused a boot failure regression on the Integrator machines.
The problem is probably caused by fiddling too much with
the device tree population in the OF init function, such
as passing the SoC bus device as parent when populating
the device tree.
This patch fixes the problem by:
- Avoiding to explicitly look up the tree root
- Look up devices needed before device population from
the match only, passing NULL as root
- Passing NULL as root and parent when calling
of_platform_populate()
After this the Integrators boot again. Tested on
Integrator/AP and Integrator/CP.

The detour through plat-versatile/sched-clock.c is hard to migrate
to multiplatform set-up and it's very little code being duplicated
so let's just inline the sched_clock registration and cut one more
dependency to plat-versatile.
This also makes this sched_clock implementation compulsory.

This atomic commit changes the Integrator clock implementation
and the machines to register clocks from the device tree and
use these instead of the previous hard-coded clocks.
In the clock implementation all hard-coded clocks and the
special initialization function call goes away, and is
replaced by two compatible strings for the two clocks
available on the core module.

Move the integrator-cp timer init to timer-sp.c and use CLKSRC_OF. There is
no reason to use the aliases, so drop them from the init code.
The integrator-cp timers are mistakenly called sp804 timers in the dts, but
in fact they are not sp804 dual timers, but single timers with the same
programming model. Fix the dts to reflect this.

Pull ARM SoC cleanups from Arnd Bergmann:
"A large number of cleanups, all over the platforms. This is dominated
largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
others moving code out of arch/arm into more appropriate subsystems.
The clocksource and irqchip drivers are now abstracted to the point
where platforms that are already cleaned up do not need to even
specify the driver they use, it can all get configured from the device
tree as we do for normal device drivers. The clocksource changes
basically touch every single platform in the process.
We further clean up the use of platform specific header files here,
with the goal of turning more of the platforms over to being
"multiplatform" enabled, which implies that they cannot expose their
headers to architecture independent code any more.
It is expected that no functional changes are part of the cleanup.
The overall reduction in total code lines is mostly the result of
removing broken and obsolete code."

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:

Two new platforms have been added, the sunxi platforms (Allwinner A1x
SoCs) by Maxime Ripard, and a generic Broadcom platform for a new

keep the platform code generic enough to have them all share one mach
directory. The new Broadcom platform is contributed by Christian
Daudt.
Highbank has grown support for Calxeda's next generation of hardware,
ECX-2000.
clps711x has seen a lot of cleanup from Alexander Shiyan, and he's
also taken on maintainership of the platform.
Beyond this there has been a bunch of work from a number of people on
converting more platforms to IRQ domains, pinctrl conversion, cleanup
and general feature enablement across most of the active platforms."

This pushes the dependencies on the Integrator/AP system
controller (SC) down into the PCI V3 driver and the
AP-specific board file.
First, the platform data for the PL010 UART is moved into
the integrator_ap.c board file, and the Integrator/CP is
assigned with NULL pdata. This way the callback functions
can reference the dynamically remapped AP syscon address
in both the ATAG and DT boot path, and this remapping
is localized to the board file.
Second the PCIv3 driver is making its own dynamic remapping
of the SC for the few registers it is using. When we
convert the PCIv3 driver over to using device tree having a
dynamically assigned base address will be useful, but we
will have to use the definition from <mach/platform.h> for
now, the only improvement is that it's done dynamically.

The Integrators were using the .nr_irqs field of the machine
descriptor to pre-allocate a number of descriptors at boot. This
is not right: the irq chip implementations should allocate
their descriptors themselves, and as a result the simple
irqdomain code warns about it.
Get rid of this by just deleting the .nr_irq field from the
machine descriptors but take care: doing so makes the default
implementation hog the first 16 IRQ numbers, so these cannot
be used by the still static IRQ number assignments in the
ATAG boot case. So for these, bump the IRQ numbers to begin
at 64 and upward.
Introduce an offset to offset all IRQ numbers if need be,
though we don't expect to do that again as device tree comes
along.

This converts the Integrator platform to use common clock
and the ICST driver. Since from this point not all ARM
reference platforms use the clock, we define
CONFIG_PLAT_VERSATILE_CLOCK and select it for all platforms
except the Integrator.
Open issue: I could not use the .init_early() field of the
machine descriptor to initialize the clocks, but had to
move them to .init_irq(), so presumably .init_early() is
so early that common clock is not up, and .init_machine()
is too late since it's needed for the clockevent/clocksource
initialization. Any suggestions on how to solve this is
very welcome.

This does two things to the FPGA IRQ controller in the versatile
family:
- Convert to MULTI_IRQ_HANDLER so we can drop the entry macro
from the Integrator. The C IRQ handler was inspired from
arch/arm/common/vic.c, recent bug discovered in this handler was
accounted for.
- Convert to using IRQ domains so we can get rid of the NO_IRQ
mess and proceed with device tree and such stuff.
As part of the exercise, bump all the low IRQ numbers on the
Integrator PIC to start from 1 rather than 0, since IRQ 0 is
now NO_IRQ. The Linux IRQ numbers are thus entirely decoupled
from the hardware IRQ numbers in this controller.
I was unable to split this patch. The main reason is the half-done
conversion to device tree in Versatile.
