The cavium,pci-thunder-ecam devices are exactly ECAM-based PCI root
complexes. These root complexes (loosely referred to as ECAM units in the
hardware manuals) are used to access the Thunder on-chip devices. They
are special in that all the BARs on devices behind these root complexes are
at fixed addresses.
Add a driver for these devices that synthesizes Enhanced Allocation (EA)
capability entries for each BAR.
Since this EA synthesis is needed for exactly two chip models, we can hard-
code some assumptions about the device topology and the layout of the
config space of specific DEVFNs in the driver.

the hardware design.
1. HIDMA Management driver
2. HIDMA Channel driver
Each HIDMA HW consists of multiple channels. These channels share some set
of common parameters. These parameters are initialized by the management
driver during power up. Same management driver is used for monitoring the
execution of the channels. Management driver can change the performance
behavior dynamically such as bandwidth allocation and prioritization.
The management driver is executed in host context and is the main
management entity for all channels provided by the device.

Yes, all of these are needed. :) This is admittedly a bit odd, but
kvm-unit-tests access.flat tests this if you run it with "-cpu host"
and of course ept=0.
KVM runs the guest with CR0.WP=1, so it must handle supervisor writes
specially when pte.u=1/pte.w=0/CR0.WP=0. Such writes cause a fault
when U=1 and W=0 in the SPTE, but they must succeed because CR0.WP=0.
When KVM gets the fault, it sets U=0 and W=1 in the shadow PTE and
restarts execution. This will still cause a user write to fault, while
supervisor writes will succeed. User reads will fault spuriously now,
and KVM will then flip U and W again in the SPTE (U=1, W=0). User reads
will be enabled and supervisor writes disabled, going back to the
originary situation where supervisor writes fault spuriously.
When SMEP is in effect, however, U=0 will enable kernel execution of
this page. To avoid this, KVM also sets NX=1 in the shadow PTE together
with U=0. If the guest has not enabled NX, the result is a continuous
stream of page faults due to the NX bit being reserved.
The fix is to force EFER.NX=1 even if the CPU is taking care of the EFER
switch. (All machines with SMEP have the CPU_LOAD_IA32_EFER vm-entry
control, so they do not use user-return notifiers for EFER---if they did,
EFER.NX would be forced to the same value as the host).
There is another bug in the reserved bit check, which I've split to a
separate patch for easier application to stable kernels.

flash operation itself is driven from a user-land tool.
Once flashing is successful, an rtas call is made to update the device

Merge tag 'kvm-arm-for-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/ARM updates for 4.6
- VHE support so that we can run the kernel at EL2 on ARMv8.1 systems
- PMU support for guests
- 32bit world switch rewritten in C
- Various optimizations to the vgic save/restore code
Conflicts:
include/uapi/linux/kvm.h
In the add-on file for the GIC dealing with the RealView family
we currently only handle the PB11MPCore, let's extend this to
manage the RealView EB ARM11MPCore as well. The Revision B of the
ARM11MPCore core tile is a bit special and needs special handling
as it moves a system control register around at random.

This patch adds support for the mcp23s18 which is very similar to
the mcp23s17. A couple of control bits are not the same.
Notable IOCON_HAEN (s17 only) & IOCON_INTCC. Which can be ignored.
Patch changes the following:
- Add mcp23s18 types.
- Always set mirror bit if the dts defines mcp23s18. regardless of type.
Mirror bit is ignored on 8 bit devices anyway.
- In mcp23s08_probe use chip.ngpio instead of logic based on type
to determine number of gpio lins to increment by. This is set
appropiately by the call to mcp23s08_probe_one.
- Add mcp23s18 to device tree documentation.
- Remove statement that irqs don't work for spi. They do.
Tested with mcp23s18.

The altr,interrupt-trigger property is not used by the driver.
Instead, altr,interrupt-type is used by the driver and the driver
does not probe if this property is not specified. Therefore, it
is expected that there are no users of the -trigger property in
the wild and that this is a typo in the documentation for the
altera-pio controller. This patch fixes the typo.

Patch based on a previous series by Shashank Sharma.
This introduces optional properties to enable color correction at the
pipe level. It relies on 3 transformations applied to every pixels
displayed. First a lookup into a degamma table, then a multiplication
of the rgb components by a 3x3 matrix and finally another lookup into
a gamma table.
The following properties can be added to a pipe :
- DEGAMMA_LUT : blob containing degamma LUT
- DEGAMMA_LUT_SIZE : number of elements in DEGAMMA_LUT
- CTM : transformation matrix applied after the degamma LUT
- GAMMA_LUT : blob containing gamma LUT
- GAMMA_LUT_SIZE : number of elements in GAMMA_LUT
DEGAMMA_LUT_SIZE and GAMMA_LUT_SIZE are read only properties, set by
the driver to tell userspace applications what sizes should be the
lookup tables in DEGAMMA_LUT and GAMMA_LUT.
A helper is also provided so legacy gamma correction is redirected
through these new properties.
v2: Register LUT size properties as range
v3: Fix round in drm_color_lut_get_value() helper
More docs on how degamma/gamma properties are used
v4: Update contributors
v5: Rename CTM_MATRIX property to CTM (Doh!)
Add legacy gamma_set atomic helper
Describe CTM/LUT acronyms in the kernel doc
v6: Fix missing blob unref in drm_atomic_helper_crtc_reset

* start adding support for qca4019 chip
ath9k
* add device ID for Toshiba WLM-20U2/GN-1080
* allow more than one interface on DFS channels
The icn, act2000 and pcbit drivers are all for very old hardware,
and it is highly unlikely that anyone is actually still using them
on modern kernels, if at all.
All three drivers apparently are for hardware that predates PCI
being the common connector, as they are ISA-only and active
PCI ISDN cards were widely available in the 1990s.
Looking through the git logs, it I cannot find any indication of a
patch to any of these drivers that has been tested on real hardware,
only cleanups or global API changes.

Although most of USB devices are hot-plug's, there are still some devices
are hard wired on the board, eg, for HSIC and SSIC interface USB devices.
If these kinds of USB devices are multiple functions, and they can supply
other interfaces like i2c, gpios for other devices, we may need to
describe these at device tree.
In this commit, it uses "reg" in dts as physical port number to match
the phyiscal port number decided by USB core, if they are the same,
then the device node is for the device we are creating for USB core.

Merge tag 'usb-for-v4.6' of http://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
Felipe writes:
usb changes for v4.6 merge window
This is almost all under drivers/usb/dwc2/. Many
changes to the host side implementation of dwc2 have
been done by Douglas Anderson.
We also have USB 3.1 support added to the Gadget
Framework and, because of that work, dwc3 got
support to Synopsys new DWC_usb31 IP core.
Other than these 2 important series, we also have
the usual collection of non-critical fixes,
Documentation updates, and minor changes all over
the place.

Currently, network /system cross-timestamping is performed in the
PTP_SYS_OFFSET ioctl. The PTP clock driver reads gettimeofday() and
the gettime64() callback provided by the driver. The cross-timestamp
is best effort where the latency between the capture of system time
(getnstimeofday()) and the device time (driver callback) may be
significant.
The getcrosststamp() callback and corresponding PTP_SYS_OFFSET_PRECISE
ioctl allows the driver to perform this device/system correlation when
for example cross timestamp hardware is available. Modern Intel
systems can do this for onboard Ethernet controllers using the ART
counter. There is virtually zero latency between captures of the ART
and network device clock.
The capabilities ioctl (PTP_CLOCK_GETCAPS), is augmented allowing
applications to query whether or not drivers implement the
getcrosststamp callback, providing more precise cross timestamping.

This reverts commit 82c2ffeb21 ("[media] tvp5150: document input
connectors DT bindings") since the DT binding is too device driver
specific and should instead be more generic and use the bindings
in Documentation/devicetree/bindings/display/connector/ and linked
to the tvp5150 using the OF graph port and endpoints.
There are still ongoing discussions about how the input connectors
will be supported by the Media Controller framework so until that
is settled, it is better to revert the connectors portion of the
bindings to avoid known to be broken bindings docs to hit mainline.

The DSI driver is currently unaware of how the DSI physical data lanes
are mapped to the logical lanes provided by the DSI controller.
Create a DT binding "qcom,data-lane-map" that provides this information
on a given platform.
The MSM DSI controller is restricted in terms of what all mappings
it can support. The lane polarity is fixed for all the lanes, the clock
lanes are fixed, and the data lanes can be swapped among each other only
for a few combinations. Apply these restrictions when we parse the DT
data.

This patch restructures the DMA bus settings and this is done
by introducing a new platform structure used for programming
the AXI Bus Mode Register inside the DMA module.
This structure can be populated from device-tree as documented in the
binding txt file.
After initializing the DMA, the AXI register can be optionally tuned
for platform drivers based.
This patch also reworks some parameters to make coherent the DMA
configuration now that AXI register is introduced.
For example, the burst_len is managed by using the mentioned axi
support above; so the snps,burst-len parameter has been removed.
It makes sense to provide the AAL parameter from DT to Address-Aligned
Beats inside the Register0 and review the PBL settings when initialize
the engine.
For PCI glue, rebuilding the story of this setting, it
was added to align a configuration so not for fixing some
known problem. No issue raised after this patch.
It is safe to use the default burst length instead of
tuning it to the maximum value

Good to see several new contributors in this set - and more generally a
number of new 'faces' over this whole cycle.
Staging movements
* hmc5843
- out of staging.
* periodic RTC trigger
- driver dropped. This is an ancient driver (brings back some memories ;)
that was always somewhat of a bodge. Originally there was a driver that
never went into mainline that supported large numbers of periodict timers
on the PXA270 via this route. Discussions to have a generic periodic
timer subsystem never went anywhere. At the time RTC periodic
interrupts were real - now they are emulated using high resolution
timers so with the HRT driver this has become pointless.
New device support
* mpu6050 driver
- Add support for the mpu6500.
* TI tpl0102 potentiometer
- new driver.
* Vybrid SoC DAC
- new driver. The ADC on this SoC has been supported for a while, this
adds a separate driver for the DAC.
New Features
* hmc5844
- Attributes to configure the bias current (typically part of a self test)
This could be done before via a somewhat obscure custom interface.
This at least makes it easy to tell what is going on.
- Document all custom attributes.
* mpu6050
- Add support for calibration offset control and readback.
* ms5611
- power regulator support. This is always one that gets added the
first time someone has a board that needs it. Here it was needed,
hence it was added.
Cleanups / minor fixes
* tree wide
- clean up all the myriad different return values in response to a
failure of i2c_check_functionality. After discussions everyone seemed
happy wiht -EOPNOTSUPP which seems to describe the situation well.
I encouraged a tree wide cleanup to set a good example in future for
this.
* core
- Typos in the iio_event_spec documentation in iio.h
* afe4403
- select REGMAP_SPI to avoid dependency issues
- mark suspend/resume as __maybe_unused to avoid warnings
* afe4404
- mark suspend/resume as __maybe_unused to avoid warnings
* atlas-ph-sensor
- switch the regmap cache type from linear to rbtree to gain reading of
registers on initial startup. It's not immediately obvious, but

Jonathan writes:
Third set of IIO new device support, features and cleanups for the 4.6 cycle.
Good to see several new contributors in this set - and more generally a
number of new 'faces' over this whole cycle.
Staging movements
* hmc5843
- out of staging.
* periodic RTC trigger
- driver dropped. This is an ancient driver (brings back some memories ;)
that was always somewhat of a bodge. Originally there was a driver that
never went into mainline that supported large numbers of periodict timers
on the PXA270 via this route. Discussions to have a generic periodic
timer subsystem never went anywhere. At the time RTC periodic
interrupts were real - now they are emulated using high resolution
timers so with the HRT driver this has become pointless.
New device support
* mpu6050 driver
- Add support for the mpu6500.
* TI tpl0102 potentiometer
- new driver.
* Vybrid SoC DAC
- new driver. The ADC on this SoC has been supported for a while, this
adds a separate driver for the DAC.
New Features
* hmc5844
- Attributes to configure the bias current (typically part of a self test)
This could be done before via a somewhat obscure custom interface.
This at least makes it easy to tell what is going on.
- Document all custom attributes.
* mpu6050
- Add support for calibration offset control and readback.
* ms5611
- power regulator support. This is always one that gets added the
first time someone has a board that needs it. Here it was needed,
hence it was added.
Cleanups / minor fixes
* tree wide
- clean up all the myriad different return values in response to a
failure of i2c_check_functionality. After discussions everyone seemed
happy wiht -EOPNOTSUPP which seems to describe the situation well.
I encouraged a tree wide cleanup to set a good example in future for
this.
* core
- Typos in the iio_event_spec documentation in iio.h
* afe4403
- select REGMAP_SPI to avoid dependency issues
- mark suspend/resume as __maybe_unused to avoid warnings
* afe4404
- mark suspend/resume as __maybe_unused to avoid warnings
* atlas-ph-sensor
- switch the regmap cache type from linear to rbtree to gain reading of
registers on initial startup. It's not immediately obvious, but
regmap flat is meant for high performances cases so doesn't read these
registers.
- use regmap_bulk_read in one case where it was using
i2c_smbus_read_i2c_block_data directly (unlike everything else that was
through regmap).
* ina2xx
- stype cleanups (lots of them!)
* isl29018
- Get the struct device back from regmap rather than storing another
copy of it in the private data. This cleanup makes sense in a number
of other drivers so patches may well follow.
* mpu6050
- style cleanups (lots of them!)
- improved return value handling
- use usleep_range to avoid the usual issues with very short msleeps.
- add some missing documentation.
* ms5611
- use the probed device name for the device rather than the driver name.
- select IIO_BUFFER to avoid dependency issues
* palmas
- drop IRQF_EARLY_RESUME as no longer needed after genirq changes.
On dm814x we have 13 ADPLLs with 3 to 4 outputs on each. The
ADPLLs have several dividers and muxes controlled by a shared
control register for each PLL.
Note that for the clocks to work as device drivers for booting on
dm814x, this patch depends on "ARM: OMAP2+: Change core_initcall
levels to postcore_initcall" that has already been merged.
Also note that this patch does not implement clk_set_rate for the
PLL, that will be posted later on when available.

The existing KVM_CREATE_SPAPR_TCE only supports 32bit windows which is not
enough for directly mapped windows as the guest can get more than 4GB.
This adds KVM_CREATE_SPAPR_TCE_64 ioctl and advertises it
via KVM_CAP_SPAPR_TCE_64 capability. The table size is checked against
the locked memory limit.
Since 64bit windows are to support Dynamic DMA windows (DDW), let's add
@bus_offset and @page_shift which are also required by DDW.

B.A.T.M.A.N. V. Its implementation started quite some years ago,
but due to the big changes being introduced it took a while to be
discussed, designed, worked, re-worked, tested and debugged (well,
we're never done with the latest). The entire operation has
basically been a team work involving all the core contributors
together with other people interested in the project.
The new protocol is divided into two main subcomponents, called
respectively ELP and OGMv2. The former is in charge of
dealing with the neighbour discovery and link quality estimation,
while the latter implements the algorithm that spreads the
metrics around the network and computes optimal paths.
The biggest change introduced with B.A.T.M.A.N. V is the new
metric: the protocol won't rely on packet loss anymore, but it
will use the estimated throughput extracted directly from the
wifi driver (when available) by querying cfg80211.
Batman-adv will also send some unicast probing packets when
an interface is not used for payload traffic to make sure that
such values are current.
The new protocol can be compiled-in or not like other
features we have and when selected will pull in CFG80211 as
dependency for the reason described above.
Thanks to the big work brought up in the past by Marek Lindner,
batman-adv can easily deal several protocol implementations,
therefore compiling in this new version does not exclude the
older.
This means that the user is offered the option to choose
the protocol when creating the mesh interface (default is the
old one to keep backward compatibility).
Along with the protocol there are some sysfs knobs that are
introduced to fine tune some of its behaviours, but users
are recommended to keep the default values unless they know
what they are doing.
The last patch is about advertising our own patchwork platform
(thanks to Sven Eckelmann for having set that up!) in the
MAINTAINERS file.

This patch adds a exynos5420 driver data to support mic_bypass
option to bypass the mic from display out path.
The mic(Mobile image compressor) compresses RGB data from fimd
and send the compressed data to the mipi dsi.
The bypass option can be founded from system register and the bit
is 11. The option bit has been introduced since exynos5420. The
only difference between exynos5250 and exynos5420/exynos5422 is
existence of the bit. Until the MIC is defined and enabled from
device tree, the bypass mic will be default option.

This patch supports mipi dsi for exynos5422. The dsi register

the values of the registers are quite different from the

Most newer Rockchip SoCs provide the possibility to use a usb-phy
as passthrough for the debug uart (uart2), making it possible to
for example get console output without needing to open the device.
This patch adds an early_initcall to enable this functionality
conditionally via the commandline and also disables the corresponding
usb controller in the devicetree.
Currently only data for the rk3288 is provided, but at least the
rk3188 and arm64 rk3368 also provide this functionality and will be
enabled later.
On a spliced usb cable the signals are tx on white wire(D+) and
rx on green wire(D-).
The one caveat is that currently the reconfiguration of the phy
happens as early_initcall, as the code depends on the unflattened
devicetree being available. Everything is fine if only a regular
console is active as the console-replay will happen after the
reconfiguation. But with earlycon active output up to smp-init
currently will get lost.
The phy is an optional property for the connected dwc2 controller,
so we still provide the phy device but fail all phy-ops with -EBUSY
to make sure the dwc2 does not try to transmit anything on the
repurposed phy.

This attribute is exported to user space to disable the link
throughput auto-detection by setting a fixed value.
The throughput override value is used when batman-adv is
computing the link throughput towards a neighbour.
If the value is set to 0 then batman-adv will try to detect
the throughput by itself.

This parameter can be set individually on each interface and
allows the configuration of the elp interval for the link
quality measurements during runtime. Usually it is desirable
to set it to a higher (= slower) value on interfaces which
have a more static characteristic (e.g. wired interfaces)
or very dense neighbourhoods to reduce overhead.

If this property is not set, the max packet size is 1023 bytes, and if
the total of packet size for pervious transactions are more than 256 bytes,
it can't accept any transactions within this frame. The use case is single
transaction, but higher frame rate.
If this property is set, the max packet size is 188 bytes, it can handle
more transactions than above case, it can accept transactions until it
considers the left room size within frame is less than 188 bytes, software

We didn't have a batch last week, so this one is slightly larger.
None of them are scary though, a handful of fixes for small DT pieces,
replacing properties with newer conventions.
Highlights:
- N900 fix for setting system revision
- onenand init fix to avoid filesystem corruption
- Clock fix for audio on Beaglebone-x15
- Fixes on shmobile to deal with CONFIG_DEBUG_RODATA (default y in 4.6)

This commit adds the base Device Tree files for the Armada 7K and 8K
SoCs, as well as the Armada 8040 DB board.
The Armada 7020, 7040 (7K family) and 8020, 8040 (8K family) are
composed of:
- An AP806 block that contains the CPU core and a few basic
peripherals. The AP806 is available in dual core configurations
(used in 7020 and 8020) and quad core configurations (used in 8020
and 8040).
- One or two CP110 blocks that contain all the high-speed interfaces
(SATA, PCIe, Ethernet, etc.). The 7K family chips have one CP110,
and the 8K family chips have two CP110, giving them twice the
number of HW interfaces.
In order to represent this from a Device Tree point of view, this
commit creates the following hierarchy:
* armada-ap806.dtsi - definitions common to dual/quad ap806
* armada-ap806-dual.dtsi - description of the two CPUs
* armada-7020.dtsi - description of the 7020 SoC
* armada-8020.dtsi - description of the 8020 SoC
* armada-ap806-quad.dtsi - description of the four CPUs
* armada-7040.dtsi - description of the 7040 SoC
* armada-7040-db.dts - description of the 7040 board
* armada-8040.dtsi - description of the 8040 SoC
The CP110 blocks are not described yet, and will be part of future
patch series.

Simply document new compatibility string.
As a previous patch adds a generic R-Car Gen2 compatibility string
there appears to be no need for a driver updates.
By documenting these compat stings they may be used in DTSs shipped, for
example as part of ROMs. They must be used in conjunction with the Gen2
fallback compat string. At this time there are no known differences between
the r8a779[234] IP blocks and that implemented by the driver for the Gen2
fallback compat string. Thus there is no need to update the driver as the
use of the Gen2 fallback compat string will activate the correct code in
the current driver while leaving the option for r8a779[234]-specific driver
code to be activated in an updated driver should the need arise.

Add fallback compatibility string for R-Car Gen 1 and Gen2.
In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 1 and Gen 2. But beyond that its not clear what the
relationship between IP blocks might be. For example, I believe that
r8a7779 is older than r8a7778 but that doesn't imply that the latter is a
descendant of the former or vice versa.
We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.
For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.

Currently, all ipv6 addresses are flushed when the interface is configured
down, including global, static addresses:
$ ip -6 addr show dev eth1
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000
inet6 2100:1::2/120 scope global

inet6 fe80::e0:f9ff:fe79:34bd/64 scope link
valid_lft forever preferred_lft forever
$ ip link set dev eth1 down
$ ip -6 addr show dev eth1
<< nothing; all addresses have been flushed>>
Add a new sysctl to make this behavior optional. The new setting defaults to
flush all addresses to maintain backwards compatibility. When the set global
addresses with no expire times are not flushed on an admin down. The sysctl
is per-interface or system-wide for all interfaces
$ sysctl -w net.ipv6.conf.eth1.keep_addr_on_down=1
or
$ sysctl -w net.ipv6.conf.all.keep_addr_on_down=1
Will keep addresses on eth1 on an admin down.

This patch adds support for APB0 in H3. It seems to be compatible with
earlier SOCs. apb0 gates controls R_ block peripherals (R_PIO, R_IR,
etc).

This patch adds support for v5 of SYSMMU controller, found in Samsung
Exynos 5433 SoCs. The main difference of v5 is support for 36-bit physical

Drivers/devices without their own rate control algorithm can get the
information what rates they should use from either the radiotap header of
injected frames or from the rate control algorithm. But the parsing of the
legacy rate information from the radiotap header was removed in commit
e6a9854b05 ("mac80211/drivers: rewrite the rate control API").
The removal of this feature heavily reduced the usefulness of frame
injection when wanting to simulate specific transmission behavior. Having
rate parsing together with MCS rates and retry support allows a fine
grained selection of the tx behavior of injected frames for these kind of
tests.

Some qcom based bootloaders identify the dtb blob based on a set
of device properties like SoC, platform, PMIC, and revisions of
those components. In downstream kernels, these values are added
to the different component dtsi files (i.e. pmic dtsi file, SoC
dtsi file, board dtsi file, etc.) via qcom specific DT
properties. The dtb files are parsed by a program called dtbTool
that picks out these properties and creates a table of contents
binary blob with the property information and some offsets into
the concatenation of all the dtbs (termed a QCDT image).
The suggestion is to do this via the board compatible string
instead, because these qcom specific properties are never used by
the kernel. Add a document describing the format of the
compatible string that encodes all this information that's
currently encoded in the qcom,{msm-id,board-id,pmic-id}
properties in downstream devicetrees. Future bootloaders may be
updated to look at the compatible field instead of looking for
the table of contents image. For non-updateable bootloaders, a
new dtbTool program will parse the compatible string and generate
a QCDT image from it.

Add the dt bindings for HiSi SAS controller v2 HW.
The main difference in the controller from dt perspective is
interrupts. The v2 controller does not have dedicated fatal and
broadcast interrupts - they are multiplexed on the channel interrupt.
Each SAS v2 controller can issue upto 64 commands (or connection
requests) on the system bus without waiting for a response - this is
know as am-max-transmissions. In hip06, sas controller #1 has a
limitation that it has to limit am-max-transmissions to 32 - this
limitation is due to chip system bus design. It is not anticipated that
any future chip incorporating v2 controller will have such a limitation.

Some DSA drivers may or may not support multiple software bridges on top
of an hardware switch.
It is more convenient for them to access the bridge's net_device for
finer configuration.
Removing the need to craft and access a bitmask also simplifies the
code.
This patch changes the signature of bridge related functions, update DSA
drivers, and removes dsa_slave_br_port_mask.
