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.

eb3d3ec567 Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into next
Pull ARM updates from Russell King:

 - Major clean-up of the L2 cache support code.  The existing mess was
   becoming rather unmaintainable through all the additions that others
   have done over time.  This turns it into a much nicer structure, and
   implements a few performance improvements as well.

 - Clean up some of the CP15 control register tweaks for alignment
   support, moving some code and data into alignment.c

 - DMA properties for ARM, from Santosh and reviewed by DT people.  This
   adds DT properties to specify bus translations we can't discover
   automatically, and to indicate whether devices are coherent.

 - Hibernation support for ARM

 - Make ftrace work with read-only text in modules

 - add suspend support for PJ4B CPUs

 - rework interrupt masking for undefined instruction handling, which
   allows us to enable interrupts earlier in the handling of these
   exceptions.

 - support for big endian page tables

 - fix stacktrace support to exclude stacktrace functions from the
   trace, and add save_stack_trace_regs() implementation so that kprobes
   can record stack traces.

 - Add support for the Cortex-A17 CPU.

 - Remove last vestiges of ARM710 support.

 - Removal of ARM "meminfo" structure, finally converting us solely to
   memblock to handle the early memory initialisation.

Pull KVM updates from Paolo Bonzini:
 "At over 200 commits, covering almost all supported architectures, this
  was a pretty active cycle for KVM.  Changes include:

   - a lot of s390 changes: optimizations, support for migration, GDB
     support and more

   - ARM changes are pretty small: support for the PSCI 0.2 hypercall
     interface on both the guest and the host (the latter acked by
     Catalin)

   - initial POWER8 and little-endian host support

   - support for running u-boot on embedded POWER targets

   - pretty large changes to MIPS too, completing the userspace
     interface and improving the handling of virtualized timer hardware

   - for x86, a larger set of changes is scheduled for 3.17.  Still, we
     have a few emulator bugfixes and support for running nested
     fully-virtualized Xen guests (para-virtualized Xen guests have
     always worked).  And some optimizations too.

  The only missing architecture here is ia64.  It's not a coincidence
  that support for KVM on ia64 is scheduled for removal in 3.17"

Pull ARM SoC driver changes from Olof Johansson:
 "SoC-near driver changes that we're merging through our tree.  Mostly
  because they depend on other changes we have staged, but in some cases
  because the driver maintainers preferred that we did it this way.

  This contains a largeish cleanup series of the omap_l3_noc bus driver,
  cpuidle rework for Exynos, some reset driver conversions and a long
  branch of TI EDMA fixes and cleanups, with more to come next release.

  The TI EDMA cleanups is a shared branch with the dmaengine tree, with
  a handful of Davinci-specific fixes on top.

  After discussion at last year's KS (and some more on the mailing
  lists), we are here adding a drivers/soc directory.  The purpose of
  this is to keep per-vendor shared code that's needed by different
  drivers but that doesn't fit into the MFD (nor drivers/platform)
  model.  We expect to keep merging contents for this hierarchy through
  arm-soc so we can keep an eye on what the vendors keep adding here and
  not making it a free-for-all to shove in crazy stuff"

Pull part one of ARM SoC updates from Olof Johansson:
 "A quite large set of SoC updates this cycle.  In no particular order:

   - Multi-cluster power management for Samsung Exynos, adding support
     for big.LITTLE CPU switching on EXYNOS5

   - SMP support for Marvell Armada 375 and 38x

   - SMP rework on Allwinner A31

   - Xilinx Zynq support for SOC_BUS, big endian

   - Marvell orion5x platform cleanup, modernizing the implementation
     and moving to DT.

   - _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
     that their platform can be enabled in the same kernel binary as
     most of the other v7 platforms in the tree.  \o/

     The work isn't quite complete, there's some driver fixes still
     needed, but the basics now work.

  New SoC support added:

   - Freescale i.MX6SX

   - LSI Axxia AXM55xx SoCs

   - Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800

   - STi STIH407

  plus a large set of various smaller updates for different platforms.

Quite a lot changes but it looks like DT approach is really paying off.
BG2Q joins Berlin SoC family with corresponding development board, DW
gpio nodes for all SoCs. Most notably, we have settled clock bindings
to allow us to continue on drivers requiring clocks and pinctrl bindings.
Last but not least, BG2Q gained SDHCI support and is able to properly
boot into userspace.

Patches from Anders Berg applied individually:

Here is version 4 of platform support for AXM5516 SoC.

The clk driver is now applied to clk-next. The rest should be ready for
arm-soc. Haven't got any response from the power/reset maintainers... I hope
this driver can be taken via arm-soc as well.

The AXM55xx family consists of devices that may contain up to 16 ARM Cortex-A15
cores (in a 4x4 cluster configuration). The cores within each cluster share an
L2 cache, and the clusters are connected to each other via a CCN-504 cache
coherent interconnect.

This machine requires CONFIG_ARM_LPAE enabled as all peripherals are located
above 4GB in the memory map.

Merge "dts: socfpga: general updates for the socfpga platform" from Dinh
Nguyen:

Mostly DTS additions to the SOCFPGA platform from Steffan Trumtrar, and a
couple of device tree documentation updates/typo fix.

This one does not the GPIO binding patch, as that is pending further
discussion. Also, v3 fixes a rebase artifact and compile tested.

974cc7b934 mfd: vexpress: Define the device as MFD cells
This patch - finally, after over 6 months! :-( - addresses
Samuel's request to split the vexpress-sysreg driver into
smaller portions and define the device in a form of MFD
cells:

* LEDs code has been completely removed and replaced with
  "gpio-leds" nodes in the tree (referencing dedicated
  GPIO subnodes in sysreg - bindings documentation updated);
  this also better fits the reality as some variants of the
  motherboard don't have all the LEDs populated

* syscfg bridge code has been extracted into a separate
  driver (placed in drivers/misc for no better place)

* all the ID & MISC registers are defined as sysconf
  making them available for other drivers should they need
  to use them (and also to the user via /sys/kernel/debug/regmap
  which can be helpful in platform debugging)

3b9334ac83 mfd: vexpress: Convert custom func API to regmap
Components of the Versatile Express platform (configuration
microcontrollers on motherboard and daughterboards in particular)
talk to each other over a custom configuration bus. They
provide miscellaneous functions (from clock generator control
to energy sensors) which are represented as platform devices
(and Device Tree nodes). The transactions on the bus can
be generated by different "bridges" in the system, some
of which are universal for the whole platform (for the price
of high transfer latencies), others restricted to a subsystem
(but much faster).

Until now drivers for such functions were using custom "func"
API, which is being replaced in this patch by regmap calls.
This required:

* a rework (and move to drivers/bus directory, as suggested
  by Samuel and Arnd) of the config bus core, which is much
  simpler now and uses device model infrastructure (class)
  to keep track of the bridges; non-DT case (soon to be
  retired anyway) is simply covered by a special device
  registration function

* the new config-bus driver also takes over device population,
  so there is no need for special matching table for
  of_platform_populate nor "simple-bus" hack in the arm64
  model dtsi file (relevant bindings documentation has
  been updated); this allows all the vexpress devices
  fit into normal device model, making it possible
  to remove plenty of early inits and other hacks in
  the near future

* adaptation of the syscfg bridge implementation in the
  sysreg driver, again making it much simpler; there is
  a special case of the "energy" function spanning two
  registers, where they should be both defined in the tree
  now, but backward compatibility is maintained in the code

* modification of the relevant drivers:

  * hwmon - just a straight-forward API change
  * power/reset driver - API change
  * regulator - API change plus error handling
    simplification
  * osc clock driver - this one required larger rework
    in order to turn in into a standard platform driver

e1cd3b361a Documentation: devicetree: Add new binding for PSCIv0.2
The PSCI v0.2+ spec defines standard values for PSCI function IDs.
Add a new binding entry so that pre v0.2 implementations can
use DT entries for function IDs and v0.2+ implementations use
standard entries as defined by the PSCIv0.2 specification.

b4bca24957 ARM: mvebu: add Armada 38x compatible string to pmsu
Since the Armada 38x PMSU registers are slightly different than the
Armada 370/XP PMSU ones, we introduce a new compatible string
"armada-380-pmsu" in the PMSU driver. These differences are not
visible for the current usage of the PMSU, but they might become
visible in the future.
