Pull ARM SoC cleanups from Arnd Bergmann:
"The remaining cleanups for 3.19 are to a large part result of
devicetree conversion nearing completion on two other platforms
besides AT91:
- Like AT91, Renesas shmobile is in the process to migrate to DT and
multiplatform, but using a different approach of doing it one SoC
at a time. For 3.19, the r8a7791 platform and associated "Koelsch"
board are considered complete and we remove the non-DT
non-multiplatform support for this.
- The ARM Versatile Express has supported DT and multiplatform for a
long time, but we have still kept the legacy board files around,
because not all drivers were fully working before. We have finally
taken the last step to remove the board files.
Other changes in this branch are preparation for the later branches or
just unrelated to the more interesting changes:
- The dts files for arm64 get moved into per-vendor directories for a
clearer structure.
- Some dead code removal (zynq, exynos, davinci, imx)
- Using pr_*() macros more consistently instead of printk(KERN_*) in
some platform code"

4bf7753b8ab7c704ca864b1653367ea9cfe68a25 introduced compilation errors
("error: 'NR_IRQS_LEGACY' undeclared (first use in this function)") because
they remove the asm/irq.h inclusion while the init_time function needs it
for the NR_IRQS_LEGACY definition.
In the other hand, the point of these commits is to remove board file
support, and init_time is only needed when booting non-DT boards, we can
thus safely remove init_time functions.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanup on mach-at91 from Arnd Bergmann:
"On Atmel AT91, the conversion to device tree is now considered
complete, and all machines that were not already converted in 3.18 are
assumed to be unused and dropped by the maintainer.
All remaining board files that were written in C are dropped, and the
ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed
altogether. Cleaning up the last pieces was great fun, so I took the
time to do some of the coding myself and removed several hundred code
lines that ended up unused after the board files were done.
There are still a couple of AT91 specific device drivers that are not
converted to DT (CF, USB-OTG) and currently not working, and the
platform itself is not "multiplatform"-enabled, but both issues are
going to be taken care of in the 3.20 cycle.
This is split out from the other cleanups purely based on the size of
the branch"

As there is currently no-one to take care of this old !MMU target and as its
support in recent kernels is a bit rotten, remove this at91x40 support and the
board file associated with it (at91eb01).
There are modern ARM !MMU in Mainline now so this target is not interesting for
building tests anymore. It would be better to start from these modern ARM !MMU
platforms to reintroduce at91x40 support if needed.

Clearing obj-y, obj-m, obj-n, obj- in each Makefile is
a useless habit.
They are non-exported variables; therefore they are always empty
whenever descending into each subdirectory.
(Moreorver, obj-y and obj-m are also set to empty at the beginning
of scripts/Makefile.build)

Pull ARM SoC driver updates from Arnd Bergmann:
"These are changes for drivers that are intimately tied to some SoC and
for some reason could not get merged through the respective subsystem
maintainer tree.
Most of the new code is for the Keystone Navigator driver, which is
new base support that is going to be needed for their hardware
accelerated network driver and other units.
Most of the commits are for moving old code around from at91 and omap
for things that are done in device drivers nowadays.
- at91: move reset, poweroff, memory and clocksource code into
drivers directories
- socfpga: add edac driver (through arm-soc, as requested by Boris)
- omap: move omap-intc code to drivers/irqchip
- sunxi: added an RTC driver for sun6i
- omap: mailbox driver related changes
- keystone: support for the "Navigator" component
- versatile: new reboot, led and soc drivers"
* tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (92 commits)
bus: arm-ccn: Fix spurious warning message
leds: add device tree bindings for register bit LEDs

The timer driver is using some global variables to define some variables it has
to use in most of its functions, like the base address.
Use some container_of calls to have a single dynamic (and local) variable to
hold this content.
The only exception is in the !DT case, where the call chain to
at91sam926x_ioremap_pit and then at91sam926x_pit_init as init_time makes it
hard for the moment to pass the physical address of the timer.

The PIT timer driver until now had a single probe function, disregarding wether
it was probed through DT or in the old-style way. This code later on was
calling some DT function to retrieve the proper values for its base address,
interrupts and clocks.
While this was working, it was preventing the usage of CLOCKSOURCE_OF_DECLARE,
and the two different probe path were not as clearly separated as they could
be.
Rework the probe path to take this into account, and switch to
CLOCKSOURCE_OF_DECLARE.
