The imx5 pm code needs to access CCM registers. Let's remove the use
of CCM static mapping in pm code by reusing the dynamic mapping created
in clock code.

Replace the static mapping of DPLL block with dynamic mapping by
calling ioremap(). Ideally, this should be done by calling of_iomap(),
so that the physical address of DPLL can also be retrieved from device
tree. But unfortunately, DPLL blocks are not defined in DT in the first
place. So to maintain the compatibility of existing DTB, we use
ioremap() with physical address defines in the code.

The i.MX6 reference manual doesn't make a clear distinction
between the fixed clock divider and the enable gate for the
pcie and sata reference clocks. This lead to the lvds mux
inputs in the imx6q clk driver to be parented from the
ref clock (which is the divider) instead of the actual gate,
which in turn prevents the upstream clock to actually be
enabled when lvds clk out is active.
This fixes a hard machine hang regression in kernel 3.16 for
boards where only pcie is active but no sata, as with this
kernel version the imx6-pcie driver is no longer enabling
the upstream clock directly but only lvds clk out.

Pull ARM fixes from Russell King:
"Another round of ARM fixes. The largest change here is the L2 changes
to work around problems for the Armada 37x/380 devices, where most of
the size comes down to comments rather than code.
The other significant fix here is for the ptrace code, to ensure that
rewritten syscalls work as intended. This was pointed out by Kees
Cook, but Will Deacon reworked the patch to be more elegant.
The remainder are fairly trivial changes"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: 8087/1: ptrace: reload syscall number after secure_computing() check
ARM: 8086/1: Set memblock limit for nommu

ARM: 8080/1: mcpm.h: remove unused variable declaration
ARM: 8076/1: mm: add support for HW coherent systems in PL310 cache
On the syscall tracing path, we call out to secure_computing() to allow
seccomp to check the syscall number being attempted. As part of this, a
SIGTRAP may be sent to the tracer and the syscall could be re-written by
a subsequent SET_SYSCALL ptrace request. Unfortunately, this new syscall
is ignored by the current code unless TIF_SYSCALL_TRACE is also set on
the current thread.
This patch slightly reworks the enter path of the syscall tracing code
so that we always reload the syscall number from
current_thread_info()->syscall after the potential ptrace traps.

When a PL310 cache is used on a system that provides hardware
coherency, the outer cache sync operation is useless, and can be
skipped. Moreover, on some systems, it is harmful as it causes
deadlocks between the Marvell coherency mechanism, the Marvell PCIe
controller and the Cortex-A9.
To avoid this, this commit introduces a new Device Tree property
'arm,io-coherent' for the L2 cache controller node, valid only for the
PL310 cache. It identifies the usage of the PL310 cache in an I/O
coherent configuration. Internally, it makes the driver disable the
outer cache sync operation.
Note that technically speaking, a fully coherent system wouldn't
require any of the other .outer_cache operations. However, in
practice, when booting secondary CPUs, these are not yet coherent, and
therefore a set of cache maintenance operations are necessary at this
point. This explains why we keep the other .outer_cache operations and
only ->sync is disabled.
While in theory any write to a PL310 register could cause the
deadlock, in practice, disabling ->sync is sufficient to workaround
the deadlock, since the other cache maintenance operations are only
used in very specific situations.
Contrary to previous versions of this patch, this new version does not
simply NULL-ify the ->sync member, because the l2c_init_data
structures are now 'const' and therefore cannot be modified, which is
a good thing. Therefore, this patch introduces a separate
l2c_init_data instance, called of_l2c310_coherent_data.

"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.

Merge tag 'samsung-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into fixes
Merge Samsung fixes for 3.16 from Kukjin Kim:
- use WFI macro in platform_do_lowpower because exynos cpuhotplug
includes a hardcoded WFI instruction and it causes compile error
in Thumb-2 mode.
- fix GIC reg sizes for exynos4 SoCs
- remove reset timer counter value during boot and resume for mct
to fix a big jump in printk timestamps
- fix pm code to check cortex-A9 for another exynos SoCs
- don't rely on firmware's secondary_cpu_start for mcpm

On exynos mcpm systems the firmware is hardcoded to jump to an address
in SRAM (0x02073000) when secondary CPUs come up. By default the
firmware puts a bunch of code at that location. That code expects the
kernel to fill in a few slots with addresses that it uses to jump back
to the kernel's entry point for secondary CPUs.
Originally (on prerelease hardware) this firmware code contained a
bunch of workarounds to deal with boot ROM bugs. However on all
shipped hardware we simply use this code to redirect to a kernel
function for bringing up the CPUs.
Let's stop relying on the code provided by the bootloader and just
plumb in our own (simple) code jump to the kernel. This has the nice
benefit of fixing problems due to the fact that older bootloaders
(like the one shipped on the Samsung Chromebook 2) might have put
slightly different code into this location.
Once suspend/resume is implemented for systems using exynos-mcpm we'll
need to make sure we reinstall our fixed up code after resume. ...but
that's not anything new since IRAM (and thus the address of the
mcpm_entry_point) is lost across suspend/resume anyway.

The following commit:
89d7e5c mmc: sdhci-esdhc-imx: add runtime pm support
has the effect of also disabling the hardware card detect
in runtime pm.
We switch to GPIO based detection to avoid this issue.
This patch is based on:

Since commit 89d7e5c131 (mmc: sdhci-esdhc-imx: add runtime pm
support), controller based card detection / write protection is not
supported anymore by esdhc driver. Let's use GPIO for CD/WP on esdhc1
instead.
While at it, fix cd gpio polarity for esdhc2. This is wrong and
currently only works because the imx esdhc driver ignores the polarity.

Move the display {} node out of the soc {} node . This just aligns
the DT with other boards, there is no functional change.

The "port" node was misplaced in the original patch, therefore making
the LCD dysfunctional on this board. Fix this by moving the "port" DT
node into the "display {}" node.

On Marvell Armada platforms, the PMSU (Power Management Service Unit)
controls a number of power management related activities, needed for
things like suspend/resume, CPU hotplug, cpuidle or even simply SMP.
Since cpuidle support was added for Armada XP, the pmsu.c file in
arch/arm/mach-mvebu/ calls the cpu_suspend() and cpu_resume() ARM
functions, which are only available when
CONFIG_ARM_CPU_SUSPEND=y. Therefore, configurations that have
CONFIG_ARM_CPU_SUSPEND disabled due to PM_SLEEP being disabled no
longer build properly, due to undefined references to cpu_suspend()
and cpu_resume().
To fix this, this patch simply ensures CONFIG_ARM_CPU_SUSPEND is
always enabled for Marvell EBU v7 platforms. Doing things in a more
fine-grained way would require a lot of #ifdef-ery in pmsu.c to
isolate the parts that use cpu_suspend()/cpu_resume(), and those parts
would anyway have been needed as soon as either one of suspend/resume,
CPU hotplug or cpuidle was enabled.

Currently the mvebu boards need to detect the SoC revision in order to apply
some quirks needed to workaround issues found on I2C and thermal controllers
present only in very early SoC.
This detection requires PCI address translation to work, so we need to
explicitly select OF_ADDRESS_PCI.
This can be considered a partial revert of the following commit, that
wrongly removed the option selection:

Commit ca8f0b0a54 ("ARM: ensure C page table setup code follows
assembly code") did what it said on the tin, but some of the older
CPU code omitted the default cache policy from their files. This
results in the kernel running with the caches disabled. Fix this
for ARM925.
