The cpu.c and cache-l2x0.c files hold only two or three simple
functions each, and they are all called from the machine
descriptors, so we can just move them all into the same file
for simplicity and consistency.

The ux500 DT support predates the CLK_OF_DECLARE macro and calls
directly into the clk driver from platform code.
Converting this to CLK_OF_DECLARE makes the code much nicer and
similar to how modern platforms do it today. It also removes the
last user of cpu_is_u8500_family() etc.

The generic IRQ init function also enables the l2 cache
implicitly when the machine descriptor sets an .l2c_aux_mask.
Let's use that on ux500 and remove the ux500_l2x0_init()
along with the cpu_is_u8500_family checks.

The ARM core kernel already calls clocksource_of_init() so why
go to all the trouble of locating and probing this node in the
machine. CLOCKSOURCE_OF_DECLARE() will take care of it in the
clocksource driver, and thus we can also get rid of the
dangling header file <linux/clksrc-dbx500-prcmu.h>

Now that the GIC chip implementation enables IRQCHIP_SKIP_SET_WAKE and
IRQCHIP_MASK_ON_SUSPEND by default, the platforms requiring them need
not override the irqchip flags as before.
This patch removes all the users of gic_set_irqchip_flags and the

We are trying to decompose and decentralize the code in
the DB8500 PRCMU out into subdrivers. The code moved in
this patch concerns a group of functions used for
decoupling and recoupling the IRQs from the GIC. During
sleep and idle the Ux500 system will transfer all IRQ
handling to the PRCMU using these functions.
Basically we are left with the two alternatives of code
placement as:
- arch/arm/mach-ux500/pm.c - this because the code is
closely related to the GIC, and takes ownership of
some of the registers from the PRCMU related to this
PM functionality.
- drivers/mfd/db8500-prcmu-pm.c - because the code is
affecting stuff in the PRCMU register range. But then
this code needs to remap and handle GIC registers.
This patch implementation is taking the first approach.
Currently the cpuidle driver is the only piece of code
using this set of functions, but it will later also be
used by the suspend/resume code which is currently under
review.
The header file is moved to:
<linux/platform_data/arm-ux500-pm.h>
The function prototypes need to be placed in a globally
visible header since the CPUidle code is planned to move
out to drivers/cpuidle.

We cannot use a global variable stored in <mach/hardware.h> to
find the base address of the PRCMU. The real resource is already
there from the board, so use this to look up the base address
instead.
Currently the patch is kept minimal so as not to interfere with
other work being done on refactoring this driver, but at a later
point the defines using (prcmu_base + 0xnnn) need to be replaced
by pure offset defined for (0xnnn) and the base inlined with the
readl()/writel() and similar codepaths.

This patch will make an early remapping of the PRCMU, to be
used when setting up the clocks, that will call down into parts
of the PRCMU driver before it is probed.
Going forward this will be removed like this:
- The mailbox subsystem need to be merged.
http://marc.info/?l=linux-kernel&m=136314559201983&w=2
- At this point the PRCMU clock code can be moved over to the
ux500 clock driver in drivers/clk/ux500/* and maintained
there in a decentralized manner.
- This early initcall and PRCMU base parameters become part of
the ux500_clk_init() call instead.

soc_device_register() never returns NULL, it only ever returns an
error pointer or a valid pointer. Use the right function (IS_ERR())
to check this.
soc_device_to_device() only ever returns &soc_dev->dev, and so can
never return an error or NULL if the pointer passed into it was
valid, so there's no point checking its return.

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."

Pull ARM soc-specific updates from Olof Johansson:
"Most notable here is probably the addition of basic support for the
BCM2835, an SoC used in some of the Roku 2 players as well as the
much-hyped Raspberry Pi, cleaned up and contributed by Stephen Warren.
It's still early days on mainline support, with just the basics
working. But it has to start somewhere!
Beyond that there's some conversions of clock infrastructure on tegra
to common clock, misc updates for several other platforms, and OMAP
now has its own bus (under drivers/bus) to manage its devices through.
This branch adds two new directories outside of arch/arm:
drivers/irqchip for new irq controllers, and drivers/bus for the above
OMAP bus. It's expected that some of the other platforms will migrate
parts of their platforms to those directories over time as well."

The Ux500 will be able to wake up on any IRQ, so flag it with
IRQCHIP_SKIP_SET_WAKE, and we want to mask off the IRQs when
going to suspend to avoid transient effects so also flag
this with IRQCHIP_MASK_ON_SUSPEND.

Counting the U9540 and the new U8540 as a U8500 family member
does not work. Instead, split the function in two:
cpu_is_u8500_family() covering U8500 and U8520
cpu_is_ux540_family() covering U9540 and U8540
This works much better in practice. Update users to keep the
same behaviour.

Pull sweeping late_initcall cleanup for arm-soc from Olof Johansson:
"This is a patch series from Shawn Guo that moves from individual
late_initcalls() to using a member in the machine structure to invoke
a platform's late initcalls.
This cleanup is a step in the move towards multiplatform kernels since
it would reduce the need to check for compatible platforms in each and
every initcall."
Fix up trivial conflicts in arch/arm/mach-{exynos/mach-universal_c210.c,
imx/mach-cpuimx51.c, omap2/board-generic.c} due to changes nearby (and,
in the case of cpuimx51.c the board support being deleted)

Pull arm soc-specific pinctrl changes from Olof Johansson:
"With this, five platforms are moving to the relatively new pinctrl
subsystem for their pin management, replacing the older soc specific
in-kernel interfaces with common code.
There is quite a bit of net addition of code for each platform being
added to the pinctrl subsystem. But the payback comes later when
adding new boards can be done by only providing new device trees
instead."

This platform has been obsoleted and was only available inside of
ST-Ericsson, no users of this code are left in the world. This
deletes the core U5500 support entirely in the same manner as the
obsoleted U8500 silicon was previously deleted.
The cpu_is_u5500() macros that can read out the CPU ID is left
until the next kernel cycle, this makes it possible to merge
deletion of dependent drivers without breakage.
This also has the upside of removing the mailbox driver which was
our only driver that was outside the drivers/* hiearchy, now the
machine directory only handles machines and nothing else.

This adds support for the U9540 variant of the U8500 series. This
is an application processor without internal modem. This is the
most basic part with ASIC ID, CPU-related fixes, IRQ list, register
ranges, timer, UART, and L2 cache setup. This is based on a patch
by Michel Jaouen which was rewritten to fit with the latest 3.3
kernel.
ChangeLog v1->v2: deleted the irqs-db9540.h file since we expect to
migrate to using Device Tree for getting the IRQs to devices.
ChangeLog v2->v3: introduced a fixed virtual offset for the ROM
as suggested by Arnd Bergmann.
