5142c33ed8 Staging driver patches for 3.16-rc1 
Here is the big staging driver pull request for 3.16-rc1.
 
 Lots of stuff here, tons of cleanup patches, a few new drivers, and some
 removed as well, but I think we are still adding a few thousand more
 lines than we remove, due to the new drivers being bigger than the ones
 deleted.
 
 One notible bit of work did stand out, Jes Sorensen has gone on a tear,
 fixing up a wireless driver to be "more sane" than it originally was
 from the vendor, with over 500 patches merged here.  Good stuff, and a
 number of users laptops are better off for it.
 
 All of this has been in linux-next for a while.

a727eaf64f ARM: SoC driver changes 
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.

755a9ba7bf ARM: SoC devicetree updates for 3.16 
As with previous release, this continues to be among the largest branches
 we merge, with lots of new contents.
 
 New things for this release are among other things:

 - Qualcomm APQ8064 and APQ8084 SoCs and eval boards
 - Nvidia Jetson TK1 development board (Tegra T124-based)
 
 Two new SoCs that didn't need enough new platform code to stand out
 enough for me to notice when writing the SoC tag, but that adds new DT
 contents are:
 
 - TI DRA72
 - Marvell Berlin 2Q

c67d9ce166 ARM: SoC board support updates for 3.16 
The bulk of this branch is updates for Renesas Shmobile. They are still
 doing some enablement for classic boards first, and then come up with DT
 bindings when they've had a chance to learn more about the hardware. Not
 necessarily a bad way to go about it, and they're looking at moving some
 of the temporary board code resulting from it to drivers/staging instead
 to avoid the churn here.
 
 As a result of the shmobile clock cleanups, we end up merging quite a
 bit of SH code here as well. We ended up merging it here instead of in
 the cleanup branch due to the other board changes depending on it.

825f4e0271 ARM: SoC updates for 3.16 (part 1) 
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. I'm
 probably missing some important one here.

   - 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.
  I'm probably missing some important one here"

80fb974798 This is the bulk of GPIO changes for the v3.16 series: 
- We are finalizing and fixing up the gpiochip irqchip helpers
   bringing a helpful irqchip implementation into the gpiolib
   core and avoiding duplicate code and, more importantly,
   duplicate bug fixes:
 
   - Support for using the helpers with threaded interrupt
     handlers as used on sleeping GPIO-irqchips
 
   - Do not set up hardware triggers for edges or levels if
     the default IRQ type is IRQ_TYPE_NONE - some drivers
     would exploit the fact that you could get default
     initialization of the IRQ type from the core at probe()
     but if no default type is set up from the helper, we
     should not call the driver to configure anything. Wait
     until a consumer requests the interrupt instead.
 
   - Make the irqchip helpers put the GPIO irqs into their
     own lock class. The GPIO irqchips can often emit
     (harmless, but annoying) lockdep warnings about recursions
     when they are in fact just cascaded IRQs. By putting
     them into their own lock class we help the lockdep core
     to keep track of things.
 
   - Switch the tc3589x GPIO expanders to use the irqchip
     helpers
 
   - Switch the OMAP GPIO driver to use the irqchip helpers
 
   - Add some documentation for the irqchip helpers
 
   - select IRQ_DOMAIN when using the helpers since some
     platforms may not be using this by default and it's a
     strict dependency.
 
 - Continued GPIO descriptor refactoring:
 
   - Remove the one instance of gpio_to_desc() from the
     device tree code, making the OF GPIO code use GPIO
     descriptors only.
 
   - Introduce gpiod_get_optional() and
     gpiod_get_optional_index() akin to the similar
     regulator functions for cases where the use of GPIO
     is optional and not strictly required.
 
   - Make of_get_named_gpiod_flags() private - we do not
     want to unnecessarily expose APIs to drivers that
     make the gpiolib harder than necessary to maintain
     and refactor. Privatize this function.
 
 - Support "-gpio" suffix for the OF GPIO retrieveal path.
   We used to look for "foo-gpios" or just "gpios" in device
   tree nodes, but it turns out that some drivers with a
   single GPIO line will just state "foo-gpio" (singularis).
   Sigh. Support this with a fallback looking for it, as
   this simplifies driver code and handles it in core code.
 
 - Switch the ACPI GPIO core to fetch GPIOs with the
   *_cansleep function variants as the GPIO operation
   region handler can sleep, and shall be able to handle
   gpiochips that sleep.
 
 - Tons of cleanups and janitorial work from Jingoo Han,
   Axel Lin, Javier Martinez Canillas and Abdoulaye Berthe.
   Notably Jingoo cut off a ton of pointless OOM messages.
 
 - Incremental development and fixes for various drivers,
   nothing really special here.

Merge tag 'gpio-v3.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio into next

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v3.16 series.

  There is a lot of action in the GPIO subsystem doing refactorings and
  cleanups, almost as many deletions as insertions and minor feature
  growth and no new drivers this time.  Which is actually pretty nice.
  Some GPIO-related stuff will come in through the pin control tree as
  well.

  Details:

   - We are finalizing and fixing up the gpiochip irqchip helpers
     bringing a helpful irqchip implementation into the gpiolib core and
     avoiding duplicate code and, more importantly, duplicate bug fixes:

     * Support for using the helpers with threaded interrupt handlers as

06aa82e498 serial: uart: add hw flow control support configuration 
8250 uart driver currently supports only software assisted hw flow
control. The software assisted hw flow control maintains a hw_stopped
flag in the tty structure to stop and start transmission and use modem
status interrupt for the event to drive the handshake signals. This is
not needed if hw has flow control capabilities. This patch adds a
DT attribute for enabling hw flow control for a uart port. Also skip
stop and start if this flag is present in flag field of the port
structure.

e0b0baadb7 tty/serial: at91: use mctrl_gpio helpers 
On sam9x5, dedicated CTS (and RTS) pins are unusable together with the
LCDC, the EMAC, or the MMC because they share the same line.

Moreover, the USART controller doesn't handle DTR/DSR/DCD/RI signals,
so we have to control them via GPIO.

This patch permits to use GPIOs to control the CTS/RTS/DTR/DSR/DCD/RI
signals.

Pull networking fixes from David Miller:
 "It looks like a sizeble collection but this is nearly 3 weeks of bug
  fixing while you were away.

   1) Fix crashes over IPSEC tunnels with NAT, the latter can reroute
      the packet through a non-IPSEC protected path and the code has to
      be able to handle SKBs attached to routes lacking an attached xfrm
      state.  From Steffen Klassert.

   2) Fix OOPSs in ipv4 and ipv6 ipsec layers for unsupported
      sub-protocols, also from Steffen Klassert.

   3) Set local_df on fragmented netfilter skbs otherwise we won't be
      able to forward successfully, from Florian Westphal.

   4) cdc_mbim ipv6 neighbour code does __vlan_find_dev_deep without
      holding RCU lock, from Bjorn Mork.

   5) local_df test in ip_may_fragment is inverted, from Florian
      Westphal.

   6) jme driver doesn't check for DMA mapping failures, from Neil
      Horman.

   7) qlogic driver doesn't calculate number of TX queues properly, from
      Shahed Shaikh.

   8) fib_info_cnt can drift irreversibly positive if we fail to
      allocate the fi->fib_metrics array, from Sergey Popovich.

   9) Fix use after free in ip6_route_me_harder(), also from Sergey
      Popovich.

  10) When SYSCTL is disabled, we don't handle local_port_range and
      ping_group_range defaults properly at all, from Cong Wang.

  11) Unaccelerated VLAN tagged frames improperly handled by cdc_mbim
      driver, fix from Bjorn Mork.

  12) cassini driver needs nested lock annotations for TX locking, from
      Emil Goode.

  13) On init error ipv6 VTI driver can unregister pernet ops twice,
      oops.  Fix from Mahtias Krause.

  14) If macvlan device is down, don't propagate IFF_ALLMULTI changes,
      from Peter Christensen.

  15) Missing NULL pointer check while parsing netlink config options in
      ip6_tnl_validate().  From Susant Sahani.

  16) Fix handling of neighbour entries during ipv6 router reachability
      probing, from Duan Jiong.

  17) x86 and s390 JIT address randomization has some address
      calculation bugs leading to crashes, from Alexei Starovoitov and
      Heiko Carstens.

  18) Clear up those uglies with nop patching and net_get_random_once(),
      from Hannes Frederic Sowa.

  19) Option length miscalculated in ip6_append_data(), fix also from
      Hannes Frederic Sowa.

  20) A while ago we fixed a race during device unregistry when a
      namespace went down, turns out there is a second place that needs
      similar protection.  From Cong Wang.

  21) In the new Altera TSE driver multicast filtering isn't working,
      disable it and just use promisc mode until the cause is found.
      From Vince Bridgers.

  22) When we disable router enabling in ipv6 we have to flush the
      cached routes explicitly, from Duan Jiong.

  23) NBMA tunnels should not cache routes on the tunnel object because
      the key is variable, from Timo Teräs.

  24) With stacked devices GRO information in skb->cb[] can be not setup
      properly, make sure it is in all code paths.  From Eric Dumazet.

  25) Really fix stacked vlan locking, multiple levels of nesting with
      intervening non-vlan devices are possible.  From Vlad Yasevich.

  26) Fallback ipip tunnel device's mtu is not setup properly, from
      Steffen Klassert.

  27) The packet scheduler's tcindex filter can crash because we
      structure copy objects with list_head's inside, oops.  From Cong
      Wang.

  28) Fix CHECKSUM_COMPLETE handling for ipv6 GRE tunnels, from Eric
      Dumazet.

  29) In some configurations 'itag' in __mkroute_input() can end up
      being used uninitialized because of how fib_validate_source()
      works.  Fix it by explitly initializing itag to zero like all the
      other fib_validate_source() callers do, from Li RongQing"

Merge "Allwinner Core additions for 3.16, take 2" from Maxime Ripard:

  - Convert the A31 SMP operations to the CPU_METHOD_OF_DECLARE mechanism
  - Remove the reset code from the machine definition, that removes pretty much
    all the code left in mach-sunxi

* tag 'sunxi-core-for-3.16-2' of https://github.com/mripard/linux:
  ARM: sunxi: Remove init_machine callback

650052b141 Merge branch 'axxia/soc' into next/soc 
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.

* axxia/soc:
  ARM: dts: axxia: Add reset controller
  power: reset: Add Axxia system reset driver
  ARM: axxia: Adding defconfig for AXM55xx
  ARM: dts: Device tree for AXM55xx.
  ARM: Add platform support for LSI AXM55xx SoC
