24faebd641 ARM: dts: Fix TI CPSW Phy mode selection on IGEP COM AQUILA.
As this board use external clock for RMII interface we should specify 'rmii'
phy mode and 'rmii-clock-ext' to make ethernet working.

The use of FIFO in McASP can reduce the risk of audio under/overrun and

68e2eb533e ARM: OMAP2+: Make GPMC skip disabled devices
Currently, child nodes of the gpmc node are iterated and probed
regardless of their 'status' property. This means adding 'status =

526570cb20 ARM: OMAP2+: create dsp device only on OMAP3 SoCs
The DSP platform device for TI DSP/Bridge is currently
created unconditionally whenever CONFIG_TIDSPBRIDGE is
enabled. This device should only be created on OMAP34xx/
OMAP36xx SoCs, and not for other OMAP3 derived SoCs or when
booting multi-arch images on other SoCs. So, add a check for
the SoC family both before creating the device and allocating
the carveout memory for the device.

e120fb4596 ARM: dts: dra7-evm: Make VDDA_1V8_PHY supply always on
After clarification from the hardware team it was found that
this 1.8V PHY supply can't be switched OFF when SoC is Active.

Since the PHY IPs don't contain isolation logic built in the design to
allow the power rail to be switched off, there is a very high risk
of IP reliability and additional leakage paths which can result in
additional power consumption.

The only scenario where this rail can be switched off is part of Power on
reset sequencing, but it needs to be kept always-on during operation.

This patch is required for proper functionality of USB, SATA
and PCIe on DRA7-evm.

75bf757edc ARM: SoC fixes for 3.16-rc
This week's arm-soc fixes:
 
 - A set of of OMAP patches that we had missed Tony's pull request of:
   - Reset fix for am43xx
   - Proper OPP table for omap5
   - Fix for SoC detection of one of the DRA7 SoCs
   - hwmod updates to get SATA and OCP to work on omap5 (drivers merged in 3.16)
   - ... plus a handful of smaller fixes
 - sunxi needed to re-add machine specific restart code that was removed in
   anticipation of a watchdog driver being merged for 3.16, and it didn't make
   it in.
 - Marvell fixes for PCIe on SMP and a big-endian fix.
 - A trivial defconfig update to make my capri test board boot with
   bcm_defconfig again.
 
 ... and a couple of MAINTAINERS updates, one to claim new Keystone
 drivers that have been merged, and one to merge MXS and i.MX (both
 Freescale platforms).
 
 The largest diffs come from the hwmod code for omap5 and the re-add of
 the restart code on sunxi. The hwmod stuff is quite late at this point
 but it slipped through cracks repeatedly while coming up the maintainer
 chain and only affects the one SoC so risk is low.

This is needed because the watchdog counterpart of these commits was dropped,

need to reintroduce that code. Of course, the long term view is still to get
rid of that code in mach-sunxi.

6509dc74c9 ARM: mvebu: fix cpuidle implementation to work on big-endian systems
On Marvell Armada XP, when a CPU comes back from deep idle state of
cpuidle, it restarts its execution at armada_370_xp_cpu_resume(),
which puts back the CPU into the coherency, and then calls the generic
cpu_resume() function.

While this works on little-endian configurations, it doesn't work on
big-endian configurations because the CPU restarts in little-endian,
and therefore must be switched back to big-endian to operate
properly. To achieve this, a 'setend be' instruction must be executed
in big-endian configurations. However, the ARM_BE8() macro that is
used to implement nice compile-time conditional for ARM LE vs. ARM BE8
is not easily usable in inline assembly.

Therefore, this patch moves the armada_370_xp_cpu_resume() C function,
which was anyway just a block of inline assembly, into a proper
pmsu_ll.S file, and adds the appropriate ARM_BE8(setend be)
instruction.

Without this patch, an Armada XP big endian configuration with cpuidle
enabled fails to boot, as it hangs as soon as one of the CPU hits the
deep idle state.

011788907b ARM: mvebu: update L2/PCIe deadlock workaround after L2CC cleanup
Commit 497a92308a ("ARM: mvebu:
implement L2/PCIe deadlock workaround") introduced some logic in
coherency.c to adjust the PL310 cache controller Device Tree node of
Armada 375 and Armada 38x platform to include the 'arm,io-coherent'
property if the system is running with hardware I/O coherency enabled.

However, with the L2CC driver cleanup done by Russell King, the
initialization of the L2CC driver has been moved earlier, and is now
part of the init_IRQ() ARM function in
arch/arm/kernel/irq.c. Therefore, calling coherency_init() in
->init_time() is now too late, as the Device Tree property gets added
too late (after the L2CC driver has been initialized).

In order to fix this, this commit removes the ->init_time() callback
use in board-v7.c and replaces it with an ->init_irq() callback. We
therefore no longer use the default ->init_irq() callback, but we now
use the default ->init_time() callback.

In this newly introduced ->init_irq() callback, we call irqchip_init()
which is the default behavior when ->init_irq() isn't defined, and
then do the initialization related to the coherency: SCU, coherency
fabric, and mvebu-mbus (which is needed to start secondary CPUs).

752ef800a6 ARM: mvebu: move Armada 375 external abort logic as a quirk
In preparation to a small re-organization of the initialization
sequence in board-v7.c, this commit moves the registration of the
custom external abort handler on Armada 375 later in the boot
sequence, and makes it more similar to the other quirks that we
already have. There is indeed no need to register this abort handler
particularly early, it simply needs to be registered before switching
to userspace.

In addition to this, this commit makes the registration of the custom
abort handler conditional on Armada 375 Z1, because Armada 375 A0 and
later iterations are not affected by the issue.

This commit was tested on both Armada 375 Z1 and Armada 375 A0
platforms.

42309ab450 ARM: 8087/1: ptrace: reload syscall number after secure_computing() check
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.

98ea2dba65 ARM: 8076/1: mm: add support for HW coherent systems in PL310 cache
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.

bfda90cbb8 ARM: bcm: Fix bcm and multi_v7 defconfigs
BCM (Kona/capri platform) has regressed in two ways on this release. First,
bcm_defconfig no longer selected the appropriate MMC driver options due to
changes in dependencies. Secondly, the new MFD and regulator drivers were not
enabled on multi_v7_defconfig, so that caused the system to fail probing MMC
there.

Fix by enabling the new options as needed.

11f9323a48 ARM: integrator: fix OF-related regression
Commit 07e461cd7e
"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.

8dbdb8e704 ARM: mvebu: Fix the improper use of the compatible string armada38x using a wildcard
Wildcards in compatible strings should be avoid. "marvell,armada38x"
was recently introduced but was not yet used.

The armada 385 SoC is a superset of the armada 380 SoC (with more CPUs
and more PCIe slots). So this patch replaces the use of
"marvell,armada38x" by the "marvell,armada380" string.

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

7cbcb9d46f ARM: EXYNOS: 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.

While at it, fix cd gpio polarity for esdhc2. This is wrong and

52fcc56753 ARM: mvebu: select ARM_CPU_SUSPEND for Marvell EBU v7 platforms
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.

ed2d859119 ARM: mvebu: Fix broken SoC ID detection
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:

6a78371ace ARM: perf: fix compiler warning with gcc 4.6.4 (and tidy code)
GCC 4.6.4 spits out the following warning when building perf_event_v7.c:

arch/arm/kernel/perf_event_v7.c: In function 'krait_pmu_get_event_idx':
arch/arm/kernel/perf_event_v7.c:1927:6: warning: 'bit' may be used uninitialized in this function

While upgrading the version of gcc may solve this, the code can also be
organised to be more efficient by not carrying more local variables than
is necessary across the armv7pmu_get_event_idx function call.  If we set
'bit' to -1 (which is invalid for clear_bit) we can use that as an
indication whether we need to clear a bit after this function.

a641f3a6ab ARM: l2c: fix dependencies on PL310 errata symbols
A number of configurations spit out warnings similar to:

warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_588369 which has unmet direct dependencies (CACHE_L2X0)
warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0)

Clean up the dependencies here:
* PL310 symbols should only be selected when CACHE_L2X0 is enabled.
* Since the cache-l2x0 code detects PL310 presence at runtime, and we will
  eventually get rid of CACHE_PL310, surround these errata options with an
  if CACHE_L2X0 conditional rather than repeating the dependency against
  each.
