13aec8e419 ARM: dts: Use better omap GPMC timings for LAN9220 
With the GPMC warnings now enabled, I noticed the LAN9220 timings
can overflow the GPMC registers with 200MHz L3 speed. Earlier we
were just skipping the bad timings and would continue with the
bootloader timings. Now we no longer allow to continue with bad
timings as we have the timings in the .dts files.

We could start using the GPMC clock divider, but let's instead
use the u-boot timings that are known to be working and a bit
faster. These are basically the u-boot NET_GPMC_CONFIG[1-6]
defines deciphered. Except that we don't set gpmc,burst-length
as that's only partially configured and does not seem to work
if fully enabled.

b5399ea845 ARM: dts: Add GPMC timings for omap zoom serial port 
The four port serial port on the zoom debug board uses a TL16CP754C
with a single interrupt and GPMC chip select. The serial ports each
use a 8 bytes for IO registers, and are 256 bytes apart on the GPMC
line.

Let's add timings for all four ports so we can remove the GPMC
workarounds for using bootloader timings.

Not caused by this patch, but looks like u-boot only properly
initializes the fifo on the first serial port. Currently the other
ports produce garbage at least with my version of u-boot. I suspect
that TL16CP754C needs non-standard initialization added to 8250
driver to properly fix this issue.

e2c5eb78a3 ARM: dts: Fix wrong GPMC size mappings for omaps 
The GPMC binding is obviously very confusing as the values
are all over the place. People seem to confuse the GPMC partition
size for the chip select, and the device IO size within the GPMC
partition easily.

The ranges entry contains the GPMC partition size. And the
reg entry contains the size of the IO registers of the
device connected to the GPMC.

Let's fix the issue according to the following table:

Device          GPMC partition size     Device IO size
connected       in the ranges entry     in the reg entry

NAND            0x01000000 (16MB)       4
16550           0x01000000 (16MB)       8
smc91x          0x01000000 (16MB)       0xf
smc911x         0x01000000 (16MB)       0xff
OneNAND         0x01000000 (16MB)       0x20000 (128KB)
16MB NOR        0x01000000 (16MB)       0x01000000 (16MB)
32MB NOR        0x02000000 (32MB)       0x02000000 (32MB)
64MB NOR        0x04000000 (64MB)       0x04000000 (64MB)
128MB NOR       0x08000000 (128MB)      0x08000000 (128MB)
256MB NOR       0x10000000 (256MB)      0x10000000 (256MB)

Let's also add comments to the fixed entries while at it.

Apparently some versions of nolo don't mux the all the necessary GPMC
pins for the smc91x probe to work properly. Let's fix this issue
by adding mux support for GPMC to the kernel.

Commit 78b81f4666 ("ARM: dts: imx28-evk: Run I2C0 at 400kHz") caused issues
when doing the following sequence in loop:

- Boot the kernel
- Perform audio playback
- Reboot the system via 'reboot' command

In many times the audio card cannot be probed, which causes playback to fail.

After restoring to the original i2c0 frequency of 100kHz there is no such
problem anymore.

This reverts commit 78b81f4666.

};

Also, this is documented in the snps-dwapb-gpio.txt.

c0fa2373f8 The clk tree changes for 3.18 are dominated by clock drivers. Mostly 
fixes and enhancements to existing drivers as well as new drivers. This
 tag contains a bit more arch code than I usually take due to some OMAP2+
 changes. Additionally it contains the restart notifier handlers which
 are merged as a dependency into several trees.
 
 The PXA changes are the only messy part. Due to having a stable tree I
 had to revert one patch and follow up with one more fix near the tip of
 this tag. Some dead code is introduced but it will soon become live code
 after 3.18-rc1 is released as the rest of the PXA family is converted
 over to the common clock framework.
 
 Another trend in this tag is that multiple vendors have started to push
 the complexity of changing their CPU frequency into the clock driver,
 whereas this used to be done in CPUfreq drivers.
 
 Changes to the clk core include a generic gpio-clock type and a
 clk_set_phase() function added to the top-level clk.h api. Due to some
 confusion on the fbdev mailing list the kernel boot parameters
 documentation was updated to further explain the clk_ignore_unused
 parameter, which is often required by users of the simplefb driver.
 Finally some fixes to the locking around the clock debugfs stuff was
 done to prevent deadlocks when interacting with other subsystems.

b528392669 ACPI and power management updates for 3.18-rc1 
- Rework the handling of wakeup IRQs by the IRQ core such that
    all of them will be switched over to "wakeup" mode in
    suspend_device_irqs() and in that mode the first interrupt
    will abort system suspend in progress or wake up the system
    if already in suspend-to-idle (or equivalent) without executing
    any interrupt handlers.  Among other things that eliminates the
    wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt
    flag with interrupts which don't really need it and should not
    use it (Thomas Gleixner and Rafael J Wysocki).
 
  - Switch over ACPI to handling wakeup interrupts with the help
    of the new mechanism introduced by the above IRQ core rework
    (Rafael J Wysocki).
 
  - Rework the core generic PM domains code to eliminate code that's
    not used, add DT support and add a generic mechanism by which
    devices can be added to PM domains automatically during
    enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).
 
  - Add debugfs-based mechanics for debugging generic PM domains
    (Maciej Matraszek).
 
  - ACPICA update to upstream version 20140828.  Included are updates
    related to the SRAT and GTDT tables and the _PSx methods are in
    the METHOD_NAME list now (Bob Moore and Hanjun Guo).
 
  - Add _OSI("Darwin") support to the ACPI core (unfortunately, that
    can't really be done in a straightforward way) to prevent
    Thunderbolt from being turned off on Apple systems after boot
    (or after resume from system suspend) and rework the ACPI Smart
    Battery Subsystem (SBS) driver to work correctly with Apple
    platforms (Matthew Garrett and Andreas Noever).
 
  - ACPI LPSS (Low-Power Subsystem) driver update cleaning up the
    code, adding support for 133MHz I2C source clock on Intel Baytrail
    to it and making it avoid using UART RTS override with Auto Flow
    Control (Heikki Krogerus).
 
  - ACPI backlight updates removing the video_set_use_native_backlight
    quirk which is not necessary any more, making the code check the
    list of output devices returned by the _DOD method to avoid
    creating acpi_video interfaces that won't work and adding a quirk
    for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak).
 
  - New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin).
 
  - Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
    Sudip Mukherjee, Yijing Wang, and Zhang Rui).
 
  - cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
    Rasmus Villemoes).
 
  - cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name
    change among other things), ppc-corenet, powernv (Viresh Kumar,
    Preeti U Murthy, Shilpasri G Bhat, Lucas Stach).
 
  - cpuidle support for DT-based idle states infrastructure, new
    ARM64 cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi,
    Rasmus Villemoes).
 
  - ARM big.LITTLE cpuidle driver updates: support for DT-based
    initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
    Kevin Hilman).
 
  - Rework of the test_suspend kernel command line argument and
    a new trace event for console resume (Srinivas Pandruvada,
    Todd E Brandt).
 
  - Second attempt to optimize swsusp_free() (hibernation core) to
    make it avoid going through all PFNs which may be way too slow on
    some systems (Joerg Roedel).
 
  - devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).
 
  - rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS
    entry update in MAINTAINERS (Heiko Stübner, Kevin Hilman).
 
  - PM core fix related to clock management (Geert Uytterhoeven).
 
  - PM core's sysfs code cleanup (Johannes Berg).

Merge tag 'pm+acpi-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "Features-wise, to me the most important this time is a rework of
  wakeup interrupts handling in the core that makes them work
  consistently across all of the available sleep states, including
  suspend-to-idle.  Many thanks to Thomas Gleixner for his help with
  this work.

  Second is an update of the generic PM domains code that has been in
  need of some care for quite a while.  Unused code is being removed, DT
  support is being added and domains are now going to be attached to
  devices in bus type code in analogy with the ACPI PM domain.  The
  majority of work here was done by Ulf Hansson who also has been the
  most active developer this time.

  Apart from this we have a traditional ACPICA update, this time to
  upstream version 20140828 and a few ACPI wakeup interrupts handling
  patches on top of the general rework mentioned above.  There also are
  several cpufreq commits including renaming the cpufreq-cpu0 driver to
  cpufreq-dt, as this is what implements generic DT-based cpufreq
  support, and a new DT-based idle states infrastructure for cpuidle.

  In addition to that, the ACPI LPSS driver is updated, ACPI support for
  Apple machines is improved, a few bugs are fixed and a few cleanups
  are made all over.

  Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
  maintained by Kevin Hilman that will be merged through the PM tree.

  Numbers-wise, the generic PM domains update takes the lead this time
  with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
  place goes to the wakeup interrupts handling rework (13 commits).

  Specifics:

   - Rework the handling of wakeup IRQs by the IRQ core such that all of
     them will be switched over to "wakeup" mode in suspend_device_irqs()
     and in that mode the first interrupt will abort system suspend in
     progress or wake up the system if already in suspend-to-idle (or
     equivalent) without executing any interrupt handlers.  Among other
     things that eliminates the wakeup-related motivation to use the
     IRQF_NO_SUSPEND interrupt flag with interrupts which don't really
     need it and should not use it (Thomas Gleixner and Rafael Wysocki)

   - Switch over ACPI to handling wakeup interrupts with the help of the
     new mechanism introduced by the above IRQ core rework (Rafael Wysocki)

   - Rework the core generic PM domains code to eliminate code that's
     not used, add DT support and add a generic mechanism by which
     devices can be added to PM domains automatically during enumeration
     (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).

   - Add debugfs-based mechanics for debugging generic PM domains
     (Maciej Matraszek).

   - ACPICA update to upstream version 20140828.  Included are updates
     related to the SRAT and GTDT tables and the _PSx methods are in the
     METHOD_NAME list now (Bob Moore and Hanjun Guo).

   - Add _OSI("Darwin") support to the ACPI core (unfortunately, that
     can't really be done in a straightforward way) to prevent
     Thunderbolt from being turned off on Apple systems after boot (or
     after resume from system suspend) and rework the ACPI Smart Battery
     Subsystem (SBS) driver to work correctly with Apple platforms
     (Matthew Garrett and Andreas Noever).

   - ACPI LPSS (Low-Power Subsystem) driver update cleaning up the code,
     adding support for 133MHz I2C source clock on Intel Baytrail to it
     and making it avoid using UART RTS override with Auto Flow Control
     (Heikki Krogerus).

   - ACPI backlight updates removing the video_set_use_native_backlight
     quirk which is not necessary any more, making the code check the
     list of output devices returned by the _DOD method to avoid
     creating acpi_video interfaces that won't work and adding a quirk
     for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak)

   - New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin)

   - Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
     Sudip Mukherjee, Yijing Wang, and Zhang Rui)

   - cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
     Rasmus Villemoes)

   - cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name change
     among other things), ppc-corenet, powernv (Viresh Kumar, Preeti U
     Murthy, Shilpasri G Bhat, Lucas Stach)

   - cpuidle support for DT-based idle states infrastructure, new ARM64
     cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi, Rasmus
     Villemoes)

   - ARM big.LITTLE cpuidle driver updates: support for DT-based
     initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
     Kevin Hilman)

   - Rework of the test_suspend kernel command line argument and a new
     trace event for console resume (Srinivas Pandruvada, Todd E Brandt)

   - Second attempt to optimize swsusp_free() (hibernation core) to make
     it avoid going through all PFNs which may be way too slow on some
     systems (Joerg Roedel)

   - devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).

   - rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS entry
     update in MAINTAINERS (Heiko Stübner, Kevin Hilman)

   - PM core fix related to clock management (Geert Uytterhoeven)

   - PM core's sysfs code cleanup (Johannes Berg)"

583f958b8a ARM: dts: fix MMC2 regulators for Exynos5420 Arndale Octa board 
Regulators for MMC2 (SD card) are PVDD_TFLASH_2V8 (LDO19) for vmmc
and PVDD_APIO_MMCOFF_2V8 (LDO13) for vqmmc.  Currently the device
tree entry for MMC2 uses PVDD_PRE_1V8 (LDO10) for vmmc and vqmmc is
not specified.  Fix it.

Without this patch:
- "mmc: dw_mmc: use mmc_regulator_get_supply to handle regulators"
  patch causes a SD card detection to fail
- "mmc: dw_mmc: Support voltage changes" patch causes a boot hang

This patch fixes both above problems.

35a9ad8af0 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next 
Pull networking updates from David Miller:
 "Most notable changes in here:

   1) By far the biggest accomplishment, thanks to a large range of
      contributors, is the addition of multi-send for transmit.  This is
      the result of discussions back in Chicago, and the hard work of
      several individuals.

      Now, when the ->ndo_start_xmit() method of a driver sees
      skb->xmit_more as true, it can choose to defer the doorbell
      telling the driver to start processing the new TX queue entires.

      skb->xmit_more means that the generic networking is guaranteed to
      call the driver immediately with another SKB to send.

      There is logic added to the qdisc layer to dequeue multiple
      packets at a time, and the handling mis-predicted offloads in
      software is now done with no locks held.

      Finally, pktgen is extended to have a "burst" parameter that can
      be used to test a multi-send implementation.

      Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
      virtio_net

      Adding support is almost trivial, so export more drivers to
      support this optimization soon.

      I want to thank, in no particular or implied order, Jesper
      Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
      Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
      David Tat, Hannes Frederic Sowa, and Rusty Russell.

   2) PTP and timestamping support in bnx2x, from Michal Kalderon.

   3) Allow adjusting the rx_copybreak threshold for a driver via
      ethtool, and add rx_copybreak support to enic driver.  From
      Govindarajulu Varadarajan.

   4) Significant enhancements to the generic PHY layer and the bcm7xxx
      driver in particular (EEE support, auto power down, etc.) from
      Florian Fainelli.

   5) Allow raw buffers to be used for flow dissection, allowing drivers
      to determine the optimal "linear pull" size for devices that DMA
      into pools of pages.  The objective is to get exactly the
      necessary amount of headers into the linear SKB area pre-pulled,
      but no more.  The new interface drivers use is eth_get_headlen().
      From WANG Cong, with driver conversions (several had their own
      by-hand duplicated implementations) by Alexander Duyck and Eric
      Dumazet.

   6) Support checksumming more smoothly and efficiently for
      encapsulations, and add "foo over UDP" facility.  From Tom
      Herbert.

   7) Add Broadcom SF2 switch driver to DSA layer, from Florian
      Fainelli.

   8) eBPF now can load programs via a system call and has an extensive
      testsuite.  Alexei Starovoitov and Daniel Borkmann.

   9) Major overhaul of the packet scheduler to use RCU in several major
      areas such as the classifiers and rate estimators.  From John
      Fastabend.

  10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
      Duyck.

  11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric
      Dumazet.

  12) Add Datacenter TCP congestion control algorithm support, From
      Florian Westphal.

  13) Reorganize sk_buff so that __copy_skb_header() is significantly
      faster.  From Eric Dumazet"

8b45bc892e ARM: SoC driver updates for 3.18 
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

212fe84a6f ARM: SoC cleanups for 3.18 
This time around, the cleanup branch contains mostly code removal. A number
 of board files for at91, imx and msm have become obsolete because of the
 DT conversion and are now ready to be removed. The OMAP platform has
 traditionally had its own DMA engine abstraction and as this is being
 phased out, a lot of the original code is now unused and can be removed
 as well.
 
 S3C24xx can be simplified now that the restart code is a proper device
 driver.
 
 Finally, a number of cleanups in shmobile are done to prepare for
 the addition of new code in other branches.

4a4743e840 ARM: SoC non-critical bug fixes for 3.18 
These are bug fixes for harmless problems that were not important
 enough to get fixed in 3.17. The majority of these are OMAP specific,
 but there are also a couple for Marvell mvebu, cns3xxx, and others,
 as well as some updates for the MAINTAINERS file.
 
 In particular, Robert Jarzmik and Daniel Mack now volunteered to help
 out maintaining the PXA platform, Krzysztof Halasa took over the
 cns3xxx platform, Carlo Caione is the maintainer for the new Amlogic
 meson platform, and Matthias Brugger is now listed for the mediatek
 platform he recently contributed.
