98b8525abb clk: sunxi: Add display and TCON0 clocks driver 
The A10 SoCs and its relatives has a special clock controller to drive the
display engines (both frontend and backend), that have a lot in common with
the clock to drive the first TCON channel.

Add a driver to support both.

923587aafc clk/axs10x: Add I2S PLL clock driver 
The ARC SDP I2S clock can be programmed using a
specific PLL.

This patch has the goal of adding a clock driver
that programs this PLL.

At this moment the rate values are hardcoded in
a table but in the future it would be ideal to
use a function which determines the PLL values
given the desired rate.

A new element got inserted into enum mx35_clks with commit 3713e3f5e9
("clk: imx35: define two clocks for rtc"). This insertion shifted most
nummerical clock assignments to a new nummerical value which in turn
rendered most hardcoded nummeric values in imx35.dtsi incorrect.

Restore the existing order by moving the newly introduced clock to the
end of the enum. Update the dts documentation accordingly.

ab98e20af5 This is first big chunk of Rockchip clock-related changes for 4.7. 
Main change is probably the added support for the new rk3399 soc
 and necessary infrastructure changes surrounding it.
 
 The biggest chunk is probably that clock code is now able to
 handle multiple clock providers in one system, as the rk3399
 has two of those. A general one and another smaller one in a
 separate power domain. The rk3399 also uses another new pll type.
 Thankfully it just fits nicely into our current structure.
 It also needs some parts like the cpuclk mux parameters to be
 a bit more flexible and an new fractional divider subtype without
 gate.
 
 Apart from this big change we have some more fixes and removal
 of forgotten variables.

Here are some final updates for ARM SoC specific dts files:
 
 * The i.MX changes were sent relatively late, and had a dependency
   on the clk tree, so I delayed that a bit. Support for the new
   i.MX6qp SoC and a couple of new boards is added in this branch.
 
 * Uniphier renames a few files to match the final product names
   that were decided by the company, kudos to the kernel developer(s)
   for getting support upstream before the product release.
   Also two boards are added. The patches were posted early enough
   and nice overall, but we forgot to apply them and decided to
   give it some more time in linux-next

Pull thermal updates from Zhang Rui:

 - Fix a regression where bogus trip points on some Lenovo laptops start
   to screw up thermal control after commit 81ad4276b5 ("Thermal:
   initialize thermal zone device correctly").

   On these Lenovo laptops, a bogus passive trip point is reported,
   which is 0 degree Celsius.  Without commit 81ad4276b5, thermal zone
   fails to set cooling devices to proper cooling state, which is a bug.
   But with commit 81ad4276b5 applied, the processors are always
   throttled on these Lenovo laptops because the current temperature is
   always higher than the passive trip point.

   Fix things to ignore such bogus trip points.  (Zhang Rui)

 - Introduce Mediatek thermal driver.  (Sascha Hauer)

 - Introduce devm_ versions of OF thermal sensor register API.  (Laxman
   Dewangan)

 - Changes in Kconfigs to allow compile test on UM arch.  (Krzysztof

  - CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started
 
  - of_clk_init() doesn't consider disabled DT nodes anymore
 
  - clk_unregister() had an error path bug squashed
 
  - of_clk_get_parent_count() has been fixed to only return unsigned ints
 
  - HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone
 
 New Drivers:
 
  - NXP LPC18xx creg
 
  - QCOM IPQ4019 GCC
 
  - TI dm814x ADPLL
 
  - i.MX6QP
 
 Updates:
 
  - Cyngus audio clks found on Broadcom iProc devices
 
  - Non-critical fixes for BCM2385 PLLs
 
  - Samsung exynos5433 updates for clk id errors, HDMI support,
    suspend/resume simplifications
 
  - USB, CAN, LVDS, and FCP clks on shmobile devices
 
  - sunxi got support for more clks on new SoCs and went through a minor
    refactoring/rewrite to use a simpler factor clk construct
 
  - rockchip added some more clk ids and added suport for fraction dividers
 
  - QCOM GDSCs in msm8996
 
  - A new devm helper to make adding custom actions simpler (acked by Greg)

  The octeon changes were applied pretty recently before the merge

  patches of a larger overhaul to this driver.  In case something goes
  wrong with them, they are easy to fix (or revert).  The advantage I
  see is that they are out of the way, and I can concentrate on the next

e531cdf50a MMC core: 
- Fix ABI regression of MMC BLK ioctl
  - Remove the unused MMC_DATA_STREAM flag
  - Enable asynchronous system PM for the host device
  - Minor fixes and clean-ups
 
 SDHCI host:
 Throughout the years, the numbers of SDHCI variants have increased and so
 has also the numbers of SDHCI callbacks/quirks. The purpose of these
 callbacks/quirks were to enable SDHCI to deal with variant specific
 requirements, but unfortunate this method didn't scale. Instead we have
 ended up with a mess. Not only did the code become suboptimal but also
 highly fragile.
 
 Lately many discussions of how to move forward with SDHCI has taken place
 at the MMC mailing list. Step by step, we aim to turn SDHCI's common code
 into a set of library functions. This will enable for optimizations and
 allow some of the existing callbacks/quirks to be removed, which also
 should help to make the code less fragile.
 
 Therefore I am also really pleased to announce that Adrian Hunter (Intel)
 has volunteered to step in as the maintainer for SDHCI.
 
 Future wise, I hope the community around SDHCI will continue to grow and
 that this release cycle can be the starting point of moving SDHCI into a
 better shape. As a matter of fact, already in this cycle the re-factoring
 has begun, but of course there are also fixes and new features included.
 Some highlights:
 
  - sdhci-iproc: Add support for Broadcom's BCM2835 eMMC IP
  - sdhci-acpi: Add support for QCOM controllers
  - sdhci-pic32: Add new SDHCI variant for PIC32MZDA

Message Manager is a hardware block used to communicate with various
processor systems within certain Texas Instrument's Keystone
generation SoCs.

This hardware engine is used to transfer messages from various compute
entities(or processors) within the SoC. It is designed to be self
contained without needing software initialization for operation.

d0e286415d irqchip/mbigen: Adjust DT bindings to handle multiple devices in a module 
A mbigen hardware module can contain more than one device node. These device
nodes contain the same register definition.

mbigen_dev1:intc_dev1 {
	...
	reg = <0x0 0xc0080000 0x0 0x10000>;
	...
};

mbigen_dev2:intc_dev2 {
	...
	reg = <0x0 0xc0080000 0x0 0x10000>;
	...
};

In this case both devices try to request the same resource resulting in a
resource conflict.

To address this problem the devices need to be subnodes of the mbigen hardware
module, which then contains the unique register space.

46e595a17d ARM: SoC driver updates for v4.6 
Driver updates for ARM SoCs, these contain various things that touch
 the drivers/ directory but got merged through arm-soc for practical
 reasons:
 
 - Rockchip rk3368 gains power domain support
 - Small updates for the ARM spmi driver
 - The Atmel PMC driver saw a larger rework, touching both
   arch/arm/mach-at91 and drivers/clk/at91
 - All reset controller driver changes alway get merged through
   arm-soc, though this time the largest change is the addition
   of a MIPS pistachio reset driver
 - One bugfix for the NXP (formerly Freescale) i.MX weim bus driver

   - Rockchip rk3368 gains power domain support
   - Small updates for the ARM spmi driver
   - The Atmel PMC driver saw a larger rework, touching both
     arch/arm/mach-at91 and drivers/clk/at91
   - All reset controller driver changes alway get merged through
     arm-soc, though this time the largest change is the addition of a
     MIPS pistachio reset driver
   - One bugfix for the NXP (formerly Freescale) i.MX weim bus driver"

915c56bc01 ARM: 64-bit DT updates for v4.6 
The arm64 device tree changes make up an increasing portion of
 the overall changes, so they are kept separate from the 32-bit
 devicetree changes and from the other arm64 updates.
 
 Newly added SoCs and boards are:
  - 96Boards Husky board
  - AMD Overdrive board
  - Amlogic S905 SoC and related Tronsmart boxes
  - Annapurna Labs Alpine family and development board
  - Broadcom Vulcan servers
  - Broadcom Northstar 2 SoC
  - Marvell Armada 3700 family and development board
  - Qualcomm MSM8996 SoC
 
 Additional devices are enabled for existing platforms from
 Applied Micro, Hisilicon, Mediatek, Qualcomm, and Renesas and
 there are a couple of other updates for Rockchip, Xilinx and
 NXP/Freescale.

Pull networking updates from David Miller:
 "Highlights:

   1) Support more Realtek wireless chips, from Jes Sorenson.

   2) New BPF types for per-cpu hash and arrap maps, from Alexei
      Starovoitov.

   3) Make several TCP sysctls per-namespace, from Nikolay Borisov.

   4) Allow the use of SO_REUSEPORT in order to do per-thread processing
   of incoming TCP/UDP connections.  The muxing can be done using a
   BPF program which hashes the incoming packet.  From Craig Gallek.

   5) Add a multiplexer for TCP streams, to provide a messaged based
      interface.  BPF programs can be used to determine the message
      boundaries.  From Tom Herbert.

   6) Add 802.1AE MACSEC support, from Sabrina Dubroca.

   7) Avoid factorial complexity when taking down an inetdev interface
      with lots of configured addresses.  We were doing things like
      traversing the entire address less for each address removed, and
      flushing the entire netfilter conntrack table for every address as
      well.

   8) Add and use SKB bulk free infrastructure, from Jesper Brouer.

   9) Allow offloading u32 classifiers to hardware, and implement for
      ixgbe, from John Fastabend.

  10) Allow configuring IRQ coalescing parameters on a per-queue basis,
      from Kan Liang.

  11) Extend ethtool so that larger link mode masks can be supported.
      From David Decotigny.

  12) Introduce devlink, which can be used to configure port link types
      (ethernet vs Infiniband, etc.), port splitting, and switch device
      level attributes as a whole.  From Jiri Pirko.

  13) Hardware offload support for flower classifiers, from Amir Vadai.

  14) Add "Local Checksum Offload".  Basically, for a tunneled packet
      the checksum of the outer header is 'constant' (because with the
      checksum field filled into the inner protocol header, the payload
      of the outer frame checksums to 'zero'), and we can take advantage
      of that in various ways.  From Edward Cree"
