Here's the big staging and iio driver update for 4.7-rc1.
I think we almost broke even with this release, only adding a few more
lines than we removed, which isn't bad overall given that there's a
bunch of new iio drivers added. The Lustre developers seem to have
woken up from their sleep and have been doing a great job in cleaning up
the code and pruning unused or old cruft, the filesystem is almost
readable :)
Other than that, just a lot of basic coding style cleanups in the churn.
All have been in linux-next for a while with no reported issues.

Pull iscsi_ibft updates from Konrad Rzeszutek Wilk:
"The pull has two features - both of them expand the SysFS entries:
- 'prefix-len' - which is subnet_mask_prefix of the iBFT header.
- 'acpi_header' dir with: 'iBFT', OEM-ID (whatever it extracts from
the iBFT header) and OEM_TABLE_ID (also whatever it extracts from
the iBFT header). This is to help NIC drivers to figure out during
bootup how to deal with BIOS created iBFT tables (like by TianoCore
UEFI implemenation)"
* 'stable/for-linus-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/ibft:
ibft: Expose iBFT acpi header via sysfs
iscsi_ibft: Add prefix-len attr and display netmask
Some ethernet adapter vendors are supplying products which support optional
(payed license) features. On some adapters this includes a hardware iscsi
initiator. The same adapters in a normal (no extra licenses) mode of
operation can be used as a software iscsi initiator. In addition, software
iscsi boot initiators are becoming a standard part of many vendors uefi
implementations. This is creating difficulties during early boot/install
determining the proper configuration method for these adapters when they
are used as a boot device.
The attached patch creates sysfs entries to expose information from the
acpi header of the ibft table. This information allows for a method to
easily determining if an ibft table was created by a ethernet card's
firmware or the system uefi/bios. In the case of a hardware initiator this
information in combination with the pci vendor and device id can be used
to ascertain any vendor specific behaviors that need to be accommodated.

In order to create a relationship model between the channels and the
management object, we are adding support for object hierarchy to the
drivers. This patch simplifies the userspace application development.
We will not have to traverse different firmware paths based on device
tree or ACPI based kernels.
No matter what flavor of kernel is used, objects will be represented as
platform devices.
The new layout is as follows:
hidmam_10: hidma-mgmt@0x5A000000 {
compatible = "qcom,hidma-mgmt-1.0";
...
hidma_10: hidma@0x5a010000 {
compatible = "qcom,hidma-1.0";
...
}
}
The hidma_mgmt_init detects each instance of the hidma-mgmt-1.0 objects
in device tree and calls into the channel driver to create platform devices
for each child of the management object.

This driver adds support for the STM CoreSight IP block, allowing any
system compoment (HW or SW) to log and aggregate messages via a
single entity.
The CoreSight STM exposes an application defined number of channels
called stimulus port. Configuration is done using entries in sysfs
and channels made available to userspace via configfs.

Some STM devices adjust software assigned master numbers depending on
the trace source and its runtime state and whatnot. This patch adds
a sysfs attribute to inform the trace-side software that master numbers
assigned to software sources will not match those in the STP stream,

accordingly.

Bit of a bumper set for new drivers but plenty of other stuff here as well!
New device support
* ad5592R ADC/DAC
- new driver supporting ad5592r and ad5593r combined ADC/DAC and gpio chips.
* Aosong am2315 relative humidity
- new driver with triggered buffer support in follow up patch.
* bmi160 imu
- new driver
* bmp280
- bmp180 support - note there is support in the misc/bmp085 driver. Intent
is to remove that driver long term.
* invensense mpu6050
- cleanup leading to explicit support of mpu9150 with a good few cleanups
along the way.
* Hope RF hp03 pressure and temperature sensor.
- new driver
* maxim DS1803 potentiometer
- new driver
* maxim max44000 light and proximity sensor
- new driver built in a series of steps to support pretty much everything.
* ROHM BH1780 light sensor
- new driver. There is an existing driver in misc that this is pretty much
intended to replace. The discussion on whether to support the non standard
interface of that driver is some way is continuing.
* st-gyro
- lsm9ds0-gyro. The accel/magn side of this will take a while longer as
extensions to the st library are needed for cases where two types of sensor
share a single i2c address.
* ti-adc081c
- support the adc101c and adc121c
* Vishay VEML6070 UV sensor
- new driver.
New features
* core
- devm_ APIs for channel_get and channel_get_all. The first user of these
is the generic ADC based thermal driver. As it is going through the
thermal tree these will be picked up as a patch to that next cycle as that
is how the author preferred to do it.
- mounting matrix support. This new core support allows devices to provide
to userspace (typically from the device tree) allowing compensation for how
the sensor is mounted on the device. First examples are on UAVs but it
has a more mundane use on typical phone where the chip may be on the front
or the back of the circuit board and soldered at any angle. Includes
support for this ABI in ak8975 (which has an older interface, now
deprecated) and mpu6050.
* tools
- add a -a option to enable all available channels in generic_buffer sample.
Makes it somewhat easier to use.
* adis library and drivers
- support manual self test flag clearing. This has technically been broken
for a very long time - result is an offset on readings as the applied field
is on all the time.
* ak8975
- triggered buffer support
* bmc150
- spi support (including splitting the driver into core and i2c parts)
* bmp280
- oversampling support.
* dht11
- improved logging - useful to debug timing issues on this quirky device.
* st-sensors

reading in bulk. This is technically a fix, but will need to be backported
if desired.

Add a new rotation matrix sysfs attribute compliant with IIO core
mounting matrix API.
Matrix is retrieved from "in_anglvel_mount_matrix" and
"in_accel_mount_matrix" sysfs attributes. It is declared into mpu6050 DTS
entry as a "mount-matrix" property.
Old interface is kept for backward userspace compatibility and may be

Expose a rotation matrix to indicate userspace the chip placement with
respect to the overall hardware system. This is needed to adjust
coordinates sampled from a sensor chip when its position deviates from the
main hardware system.
Final coordinates computation is delegated to userspace since:
* computation may involve floating point arithmetics ;
* it allows an application to combine adjustments with arbitrary
transformations.
This 3 dimentional space rotation matrix is expressed as 3x3 array of
strings to support floating point numbers. It may be retrieved from a
"[<dir>_][<type>_]mount_matrix" sysfs attribute file. It is declared into a
device / driver specific DTS property or platform data.

Failure to synchronize the PSL timebase currently prevents the
initialization of the cxl card, thus rendering the card useless. This
is too extreme for a feature which is rarely used, if at all. No
hardware AFUs or software is currently using PSL timebase.
This patch still tries to synchronize the PSL timebase when the card
is initialized, but ignores the error if it can't. Instead, it reports
a status via /sys.

Pull more power management and ACPI updates from Rafael Wysocki:
"The second batch of power management and ACPI updates for v4.6.
Included are fixups on top of the previous PM/ACPI pull request and
other material that didn't make into it but still should go into 4.6.
Among other things, there's a fix for an intel_pstate driver issue
uncovered by recent cpufreq changes, a workaround for a boot hang on
Skylake-H related to the handling of deep C-states by the platform and
a PCI/ACPI fix for the handling of IO port resources on non-x86
architectures plus some new device IDs and similar.
Specifics:
- Fix for an intel_pstate driver issue related to the handling of MSR
updates uncovered by the recent cpufreq rework (Rafael Wysocki).
- cpufreq core cleanups related to starting governors and frequency
synchronization during resume from system suspend and a locking fix
for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran).
- acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang,
Michael Neuling, Richard Cochran, Shilpasri Bhat).
- intel_idle driver update preventing some Skylake-H systems from
hanging during initialization by disabling deep C-states mishandled
by the platform in the problematic configurations (Len Brown).
- Intel Xeon Phi Processor x200 support for intel_idle
(Dasaratharaman Chandramouli).
- cpuidle menu governor updates to make it always honor PM QoS
latency constraints (and prevent C1 from being used as the fallback
C-state on x86 when they are set below its exit latency) and to
restore the previous behavior to fall back to C1 if the next timer
event is set far enough in the future that was changed in 4.4 which
led to an energy consumption regression (Rik van Riel, Rafael
Wysocki).
- New device ID for a future AMD UART controller in the ACPI driver
for AMD SoCs (Wang Hongcheng).
- Rockchip rk3399 support for the rockchip-io-domain adaptive voltage
scaling (AVS) driver (David Wu).
- ACPI PCI resources management fix for the handling of IO space

Pull i2c updates from Wolfram Sang:
"Mostly usual driver updates and improvements. The changelog should
give an idea. Standing out is the i2c-qup driver with lots of new
capabilities and we also have now an i2c-demuxer.
I'd especially like to welcome Peter Rosin as the i2c-mux maintainer.
He has an interesting series for muxes in the queue and agreed to look
after this part of the subsystem. Thank you, Peter, and welcome
again!
The octeon changes were applied pretty recently before the merge
window. I am aware. They are the first (and relatively simple)
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
block of patches. I really would like to apply the overhaul in
smaller batches to avoid regressions. And waiting a cycle for the
introductory patches seemed too much of a delay for me"

"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"

Core changes:
- The gpio_chip is now a *real device*. Until now the gpio chips
were just piggybacking the parent device or (gasp) floating in
space outside of the device model. We now finally make GPIO chips
devices. The gpio_chip will create a gpio_device which contains
a struct device, and this gpio_device struct is kept private.
Anything that needs to be kept private from the rest of the kernel
will gradually be moved over to the gpio_device.
- As a result of making the gpio_device a real device, we have added
resource management, so devm_gpiochip_add_data() will cut down on
overhead and reduce code lines. A huge slew of patches convert
almost all drivers in the subsystem to use this.
- Building on making the GPIO a real device, we add the first step
of a new userspace ABI: the GPIO character device. We take small
steps here, so we first add a pure *information* ABI and the tool
"lsgpio" that will list all GPIO devices on the system and all
lines on these devices. We can now discover GPIOs properly from
userspace. We still have not come up with a way to actually *use*
GPIOs from userspace.
- To encourage people to use the character device for the future,
we have it always-enabled when using GPIO. The old sysfs ABI is
still opt-in (and can be used in parallel), but is marked as
deprecated. We will keep it around for the foreseeable future,
but it will not be extended to cover ever more use cases.
Cleanup:
- Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
includes. This dates back to when GPIO was an opt-in feature and
no shared library even existed: just a header file with proper
prototypes was provided and all semantics were up to the arch to
implement. These patches make the GPIO chip even more a proper
device and cleans out leftovers of the old in-kernel API here
and there. Still some cruft is left but it's very little now.
- There is still some clamping of return values for .get() going
on, but we now return sane values in the vast majority of drivers
and the errorpath is sanitized. Some patches for powerpc, blackfin
and unicore still drop in.
- We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
implementations to use gpiochip_add_data() and cut down on code
lines.
- MPC8xxx is converted to use the generic GPIO helpers.
- ATH79 is converted to use the generic GPIO helpers.
New drivers:
- WinSystems WS16C48
- Acces 104-DIO-48E
- F81866 (a F7188x variant)
- Qoric (a MPC8xxx variant)
- TS-4800
- SPI serializers (pisosr): simple 74xx shift registers connected
to SPI to obtain a dirt-cheap output-only GPIO expander.

The Qualcomm Technologies HIDMA device has been designed to support
virtualization technology. The driver has been divided into two to follow
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.

Switch attribute wakeup_data from binary to a text attribute.
This makes it easier to handle in userspace and allows to
use the output of tools like mode2 almost as is to set a
wakeup sequence.
Changing to a text format and values in microseconds also
makes the userspace interface independent of the setting of
SAMPLE_PERIOD in the driver.
In addition document the new sysfs attribute in

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.
