This patch set the correct value for oversampling maxItems. In the
original example, appears 3 items for oversampling while the maxItems
is set to 1, this patch fixes those issues.

This adds support for the BMA254 variant of this
accelerometer. The only difference for the simple IIO
driver is that values are 12 bit and the temperature
offset differs by 1 degree.
Whilst wildcards in naming are normally frowned upon:
The cases where I have labeled variables "25x" is where the
models are identical, so as to make things easier for people
that want to add support for BMA253 and BMA255.

The chips have a 'start conversion' and a 'end of conversion' pair of
pins. They can be used but this is absolutely not mandatory as regular
polling is supported by the chip depending on its internal clocking
setup.
There is no physical reason to force the use of interrupts so turn
them optional.
Also, once the interrupt turned optional, these devices fit perfectly
the "trivial devices" described in the generic (yaml) bindings file, so
instead of converting this text file to json schema, we can just add
the relevant compatibles in:

Regulator '*-supply' properties are always a single phandle, so
'maxItems: 1' or a $ref is not necessary. All that's needed is either
'true' or an optional 'description'. Following this clean-up, the
meta-schema will enforce this pattern.
There's one case in tree with 'innolux,n156bge-l21' having 2 phandles.
This appears to be a mistake or abuse of simple-panel as it's 2 different
voltage rails connected to 'power-supply'.

Third version with the adis rework set dropped as better to just have
a fresh version of that at some future date.
The usual mixed backs of new device support being added to drivers,
long term reworks continuing and little per driver cleanups and
features.
Also a few trivial counter subsystem tidy ups on behalf of William.
Core new feature
* Device label support. A long requested feature no one got around to
implementing before. Allows DT based provision of a 'label' that
identifies a device uniquely within a system. This differs from existing
'name' which is meant to be the part number.
New device support
* ingenic-adc
- Support for the JZ4770 SoC ADC including bindings.
* inv_mpu6050
- Add support for magnetometer in MPU925x parts.
Fiddly to do as this is actually a separate device sitting inside the
package, but with the master device being able to schedule reads etc.
Will only run if the auxiliary bus is not in use for any other devices.
Features
* ad7192
- Userspace calibration controls to do zero and full scale.
* st_lsm6dsx
- Enable latched interrupts by default for sensors events with related clear.
- Motion events and related wakeup source. This needed quite a bit of
refactoring as well.
Cleanups and minor features
* ad7192
- sysfs ABI docs
* ad7949
- Remove code to readback configuration word as driver never actually enabled
it.
- Fix incorrect xfer length. Not actually known to cause problems other
than wasted bus usage.
* adis16080
- Replace core mlock usage with local lock with more appropriate scope.
* adis16130
- Remove pointless mlock usage.
* adis16240
- Remove include of gpio.h as no gpio usage.
* atlas-ph-sensor
- Improve logical ordering of buffer predisable / postenable functions.
This is part of a longer term rework Alexandru is driving towards.
* bh1750
- Fix up a static compiler warning and make the code more readable.
- yaml conversion of binding + MAINTAINERS entry.

The AD7192 binding describes two regulator properties, avdd-supply and

This is another huge branch with close to 450 changessets related to
devicetree files, roughly half of this for 32-bit and 64-bit respectively.
There are lots of cleanups and additional hardware support for platforms
we already support based on SoCs from Renesas, ST-Microelectronics,
Intel/Altera, Rockchips, Allwinner, Broadcom and other manufacturers.
A total of 6 new SoCs and 37 new boards gets added this time, one more
SoC will come in a follow-up branch. Most of the new boards are for
64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7.
Going more into details for SoC platforms with new hardware support:
The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone platform,
usually paired with an external 5G modem. So far we only support the
Qualcomm SM8150 MTP reference platform, but no actual products.
For the slightly older Qualcomm platforms, support for several interesting
products is getting added: Three laptops based on Snapdragon 835/MSM8998
(Asus NovaGo, HP Envy X2 and Lenovo Miix 630), one laptop based on
Snapdragon 850/sdm850 (Lenovo Yoga C630) and several phones based on
the older Snapdragon 410/MSM8916 (Samsung A3 and A5, Longcheer L8150
aka Android One 2nd gen "seed" aka Wileyfox Swift).
Mediatek MT7629 is a new wireless network router chip, similar to
the older MT7623. It gets added together with the reference board
implementation.
Allwinner V3 is a repackaged version of the existing low-end V3s chip,
and is used in the tiny Lichee Pi Zero plus, also added here. There is
also a new TV set-top box based on Allwinner H6, the Tanix TX6, and the
eMMC variant of the Olimex A64-Olinuxino development board.
NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC family,
similar to the i.MX8M Mini. As usual, there is a large number of new
boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML, SolidRun Hummingboard
Pulse baseboard and System-on-Module, Boundary Devices i.MX8MQ Nitrogen8M,
and TechNexion PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit,
we get the Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC
phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight
Innovations i.MX7 RMU2 board.
In a different NXP product line, the Layerscape LS1046A "Freeway"
reference board gets added.
Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from their
set-top-box line and smart speaker with newer CPU and GPU cores compared
to their predecessors. Both are now also supported by the Khadas VIM3
development board series, and the dts files for that get reorganized a
bit to better deal with all variants. Another board based on SM1 that
gets added is the SEI Robotics SEI610.
There are a handful of new x86 and Power9 server boards using Aspeed BMC
chips that are gaining support for running Linux on the BMC through the
OpenBMC project: Facebook Minipack/Wedge100/Wedge40, Lenovo Hr855xg2,
and Mihawk. Notably these are still new machines using SoCs based on
the ARM9 and ARM11 CPU cores, as support for the new Cortex-A7 based
AST2600 is still ramping up.
There are three new end-user products using 32-bit Rockchips SoCs:
Mecer Xtreme Mini S6 is an Android "mini PC" box based on the low-end
RK3229 chip, while the two AOpen products Chromebox Mini (Fievel) and
Chromebase Mini (Tiger) run ChromeOS and are meant for commercial settings
(digital signage, PoS, ...).
One more single-board computer based on the popular 64-bit RK3399 is
added: the Leez RK3399 P710.

Pull ARM DT updates from Arnd Bergmann:
"This is another huge branch with close to 450 changessets related to
devicetree files, roughly half of this for 32-bit and 64-bit
respectively. There are lots of cleanups and additional hardware
support for platforms we already support based on SoCs from Renesas,
ST-Microelectronics, Intel/Altera, Rockchips, Allwinner, Broadcom and
other manufacturers.
A total of 6 new SoCs and 37 new boards gets added this time, one more
SoC will come in a follow-up branch. Most of the new boards are for
64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7.
Going more into details for SoC platforms with new hardware support:
- The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone
platform, usually paired with an external 5G modem. So far we only
support the Qualcomm SM8150 MTP reference platform, but no actual
products.
- For the slightly older Qualcomm platforms, support for several
interesting products is getting added: Three laptops based on
Snapdragon 835/MSM8998 (Asus NovaGo, HP Envy X2 and Lenovo Miix
630), one laptop based on Snapdragon 850/sdm850 (Lenovo Yoga C630)
and several phones based on the older Snapdragon 410/MSM8916
(Samsung A3 and A5, Longcheer L8150 aka Android One 2nd gen "seed"
aka Wileyfox Swift).
- Mediatek MT7629 is a new wireless network router chip, similar to
the older MT7623. It gets added together with the reference board
implementation.
- Allwinner V3 is a repackaged version of the existing low-end V3s
chip, and is used in the tiny Lichee Pi Zero plus, also added here.
There is also a new TV set-top box based on Allwinner H6, the Tanix
TX6, and the eMMC variant of the Olimex A64-Olinuxino development
board.
- NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC
family, similar to the i.MX8M Mini. As usual, there is a large
number of new boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML,

The mounting matrix for sensors was introduced in
commit dfc57732ad ("iio:core: mounting matrix support")
However the device tree bindings are very terse and since this is
a widely applicable property, we need a proper binding for it
that the other bindings can reference. This will also be useful
for other operating systems and sensor engineering at large.
I think all 3D sensors should support it, the current situation
is probably that the mounting information is confined in magic
userspace components rather than using the mounting matrix, which
is not good for portability and reuse.

On stm32h7 and stm32mp1, the ADC inputs are multiplexed with analog
switches which have reduced performances when their supply is below 2.7V
(vdda by default). Booster or vdd can be used, to get full ADC
performances.
Add documentation for:
- optional booster-supply that can be used on stm32h7 and stm32mp1.
- optional vdd-supply that can be used on stm32mp1 to supply analog
circuitry, selected by syscfg.
Mark these as optional, since this is a trade-off between analog
performance and power consumption.

This patch adds the buffered mode device tree property for positive and
negative inputs. Each option can be enabled independently.
In buffered mode, the input channel feeds into a high impedance input stage
of the buffer amplifier. Therefore, the input can tolerate significant
source impedances and is tailored for direct connection to external
resistive type sensors such as strain gages or RTDs.

A number of interesting new devices supported plus a good set of staging
cleanup including one graduation and one drop.
New device support
* ad56886
- Add support for AD5674R/AD5679R with some minor driver changes to support
more channels.
* ad7768
- New driver and dt bindings for this 24 bit ADC.
* max44009
- New driver and dt bindings for this ambient light sensor.
* mpu6050
- Support the ICM 20602 IMU. Minor tweaks due to slightly different
register map.
* NPCM adc
- New driver and dt bindings for this BMC ADC.
* Sensiron SGP30
- Modifiers for ethanol and H2.
- New driver and dt bindings.
- Follow patch added self cleaning support.
* Sensiron SPS30
- New channel type for mass concentration.
- New driver and bindings.
- Minor tidy up patch followed (drop fmt specifier as unused)
* st_pressure
- lps22hh support. ID plus information structures and dt bindings.
* ti-ads124s08
- Add binding doc and driver.
Staging graduations
* ad7606 driver and bindings.
Staging drops
* ad7152 CDC driver dropped. This part is near EoL and no one is known
to be using it. If anyone surfaces obviously we can bring the driver
back. If not, good to drop it to avoid wasting anyone's time cleaning
it up.
New features
* bme680
- DT support and bindings doc.
* isl29018
- Add regulator for VCC.
* mag3110
- Add regulators for supplies.
* meson-saradc
- Support the temperature sensors of more SoCs.
* mma8452
- Add regulators for power suplies and binding docs to reflect them.
* st-accel
- Support the undocumented but it seems fairly common _ONT ACPI method
to specify orientation of the sensor.
Cleanup, minor fixes and fixes for staging driver that have been broken a
long time
* ad5933
- Drop platform data alternative to specifying the reference voltage
using a regulator.
- Use the clock framework to contorl the reference clock.
- Add a DT binding doc to cover the defacto binding.
* ad7280a
- Split up some big functions to improve readability.
* ad7606
- Allow for timeout if interrupt never occurs.
- Use devm functions to simplify probe and remove.
- Use the find_closest macro to avoid need for precise values from
userspace.
- Add missing vendor prefixes for various DT properties. Note the
driver is in staging still and there are no known devicetrees.
- Add explict OF device ID table.
- Simplify the Kconfig choices
- Change to a threaded IRQ.
- SPDX and simple stype fixes.
* ad7816
- Drop unnecessary variable init.
* ad9523
- Check a return value that was ignored.
* ad9833
- Drop platform data. It was just setting most values to the hardware
defaults.
- Use the clock framework to provide the input clock.
* adt7316 (lots of staging cleanup)
- Fix some wrong register / bit definitions
- Invert the logic of the check for an ldac pin so it actually makes sense.
- Read the right register to get internal vref settings
- Allow adt751x chips to use the internal vref for all DAC channels rather
than a subset.
- Remove dac vref bypass control from parts that don't have one.
- Make the store DAC update mode function consistent with the show one.
- Fix some spellings and other minor tidy up.
- Avoid passing irq numbers around by putting all the irq logic in
one place.
- Fix an issue with the resolution of DAC control.
- Fix support of the high resolution DAC mode (for temp proportional output)
where supported.
- Fix DAC read and write calculations.

Jonathan writes:
First set of new device support, features and cleanup for IIO in the 5.1 cycle
A number of interesting new devices supported plus a good set of staging
cleanup including one graduation and one drop.
New device support
* ad56886
- Add support for AD5674R/AD5679R with some minor driver changes to support
more channels.
* ad7768
- New driver and dt bindings for this 24 bit ADC.
* max44009
- New driver and dt bindings for this ambient light sensor.
* mpu6050
- Support the ICM 20602 IMU. Minor tweaks due to slightly different
register map.
* NPCM adc
- New driver and dt bindings for this BMC ADC.
* Sensiron SGP30
- Modifiers for ethanol and H2.
- New driver and dt bindings.
- Follow patch added self cleaning support.
* Sensiron SPS30
- New channel type for mass concentration.
- New driver and bindings.
- Minor tidy up patch followed (drop fmt specifier as unused)
* st_pressure
- lps22hh support. ID plus information structures and dt bindings.
* ti-ads124s08
- Add binding doc and driver.
Staging graduations
* ad7606 driver and bindings.
Staging drops
* ad7152 CDC driver dropped. This part is near EoL and no one is known
to be using it. If anyone surfaces obviously we can bring the driver
back. If not, good to drop it to avoid wasting anyone's time cleaning
it up.
New features
* bme680
- DT support and bindings doc.
* isl29018
- Add regulator for VCC.
* mag3110
- Add regulators for supplies.
* meson-saradc
- Support the temperature sensors of more SoCs.
* mma8452
- Add regulators for power suplies and binding docs to reflect them.
* st-accel
- Support the undocumented but it seems fairly common _ONT ACPI method
to specify orientation of the sensor.
Cleanup, minor fixes and fixes for staging driver that have been broken a
long time
* ad5933
- Drop platform data alternative to specifying the reference voltage
using a regulator.
- Use the clock framework to contorl the reference clock.
- Add a DT binding doc to cover the defacto binding.
* ad7280a
- Split up some big functions to improve readability.
* ad7606
- Allow for timeout if interrupt never occurs.
- Use devm functions to simplify probe and remove.
- Use the find_closest macro to avoid need for precise values from
userspace.
- Add missing vendor prefixes for various DT properties. Note the
driver is in staging still and there are no known devicetrees.
- Add explict OF device ID table.
- Simplify the Kconfig choices
- Change to a threaded IRQ.
- SPDX and simple stype fixes.
* ad7816
- Drop unnecessary variable init.
* ad9523
- Check a return value that was ignored.
* ad9833
- Drop platform data. It was just setting most values to the hardware
defaults.
- Use the clock framework to provide the input clock.
* adt7316 (lots of staging cleanup)
- Fix some wrong register / bit definitions
- Invert the logic of the check for an ldac pin so it actually makes sense.
- Read the right register to get internal vref settings
- Allow adt751x chips to use the internal vref for all DAC channels rather
than a subset.
- Remove dac vref bypass control from parts that don't have one.
- Make the store DAC update mode function consistent with the show one.
- Fix some spellings and other minor tidy up.
- Avoid passing irq numbers around by putting all the irq logic in
one place.
- Fix an issue with the resolution of DAC control.
- Fix support of the high resolution DAC mode (for temp proportional output)
where supported.
- Fix DAC read and write calculations.
* st_lsm6dsx
- Drop an unused variable (set but not read)
* xilinx-xadc
- Check an unhandled return value.

Meson8b and Meson8m2 use a 5-bit wide TSC (temperature sensor
coefficient). The SAR ADC registers however can only store (the lower)
4 bits. The fifth (upper-most) bit is stored inside the
MESON_HHI_DPLL_TOP_0[9] register from the HHI register area.
This adds a syscon property to the HHI register area so a driver can
fetch the HHI register map and store the fifth TSC bit in there.

As usual, this is where the bulk of our changes end up landing each
merge window.
The individual updates are too many to enumerate, many many platforms
have seen additions of device descriptions such that they are
functionally more complete (in fact, this is often the bulk of updates
we see).
Instead I've mostly focused on highlighting the new platforms below as
they are introduced. Sometimes the introduction is of mostly a fragment,
that later gets filled in on later releases, and in some cases it's
near-complete platform support. The latter is more common for derivative
platforms that already has similar support in-tree.
Two SoCs are slight outliers from the usual range of additions. Allwinner
support for F1C100s, a quite old SoC (ARMv5-based) shipping in the
Lychee Pi Nano platform. At the other end is NXP Layerscape LX2160A,
a 16-core 2.2GHz Cortex-A72 SoC with a large amount of I/O aimed at
infrastructure/networking.
TI updates stick out in the diff stats too, in particular because they
have moved the description of their L4 on-chip interconnect to devicetree,
which opens up for removal of even more of their platform-specific
'hwmod' description tables over the next few releases.
SoCs:
- Qualcomm QCS404 (4x Cortex-A53)
- Allwinner T3 (rebranded R40) and f1c100s (armv5)
- NXP i.MX7ULP (1x Cortex-A7 + 1x Cortex-M4)

This driver was originally written by ST in 2016 as a misc input device
driver, and hasn't been maintained for a long time. I grabbed some code
from it's API and reformed it into an iio proximity device driver.
This version of driver uses i2c bus to talk to the sensor and
polling for measuring completes, so no irq line is needed.
It can be tested with reading from
/sys/bus/iio/devices/iio:deviceX/in_distance_input

There is a merge commit in here to pull in regmap support for repeatedly
reading the same register (to read out FIFOs). Used by the adxl372 driver.
This will find uses elsewhere once we tidy up various drivers that are
effectively doing this and relying on not enabling regcache.
New device support
* Analog devices ADXL372 accelerometer
- new driver for this accelerometer including fifo and and interrupt support.
Follow up patches enforce trigger validation, add sampling frequency
control and filter bandwidth control. A later series added i2c support
to the existing SPI support.
* ST lsm6dsx
- rework and add support fo the LSM6DSO 6 axis mems sensor.
* Linear LTC 1660 DAC

During
initialization, it is checked if the reset property is specified and the
the GPIO is being asserted, therefore the device will become active.
When the reset function is called, if the gpio_reset var is set, then
the
GPIO will be toggled, otherwise a software reset is performed.

Here are the big staging/iio patches for 4.19-rc1.
Lots of churn here, with tons of cleanups happening in staging drivers,
a removal of an old crypto driver that no one was using (skein), and the
addition of some new IIO drivers. Also added was a "gasket" driver from
Google that needs loads of work and the erofs filesystem.
Even with adding all of the new drivers and a new filesystem, we are
only adding about 1000 lines overall to the kernel linecount, which
shows just how much cleanup happened, and how big the unused crypto
driver was.
All of these have been in the linux-next tree for a while now with no
reported issues.
Note, you will have a merge problem with a device tree IIO file and the
MAINTAINERS file, both resolutions are easy, just take all changed.
There will be a skein file merge issue as well, but that file got
deleted so just drop that.

'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

Here is the big staging and IIO driver update for 4.18-rc1.
It was delayed as I wanted to make sure the final driver deletions did
not cause any major merge issues, and all now looks good.
There are a lot of patches here, just over 1000. The diffstat summary
shows the major changes here:
1007 files changed, 16828 insertions(+), 227770 deletions(-)
Because of this, we might be close to shrinking the overall kernel
source code size for two releases in a row.
There was loads of work in this release cycle, primarily:
- tons of ks7010 driver cleanups
- lots of mt7621 driver fixes and cleanups
- most driver cleanups
- wilc1000 fixes and cleanups
- lots and lots of IIO driver cleanups and new additions
- debugfs cleanups for all staging drivers
- lots of other staging driver cleanups and fixes, the shortlog
has the full details.
but the big user-visable things here are the removal of 3 chunks of
code:
- ncpfs and ipx were removed on schedule, no one has cared about
this code since it moved to staging last year, and if it needs
to come back, it can be reverted.
- lustre file system is removed. I've ranted at the lustre
developers about once a year for the past 5 years, with no
real forward progress at all to clean things up and get the
code into the "real" part of the kernel. Given that the
lustre developers continue to work on an external tree and try
to port those changes to the in-kernel tree every once in a
while, this whole thing really really is not working out at
all. So I'm deleting it so that the developers can spend the
time working in their out-of-tree location and get things
cleaned up properly to get merged into the tree correctly at a
later date.
Because of these file removals, you will have merge issues on some of
these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
atomisp driver). Just delete those files, it's a simple merge :)
All of this has been in linux-next for a while with no reported

A nice mix this time of excellent cleanups (many to send drivers
speeding toward staging graduations) and new drivers / device support.
A good part of this is Brian Masney's never ending task on the tsl2x7x
driver. The end is in sight so hopefully we'll get that one out of
staging very soon!

Here is the big Staging and IIO driver patches for 4.16-rc1.
There is the normal amount of new IIO drivers added, like all releases.
The networking IPX and the ncpfs filesystem are moved into the staging
tree, as they are on their way out of the kernel due to lack of use
anymore.
The visorbus subsystem finall has started moving out of the staging tree
to the "real" part of the kernel, and the most and fsl-mc codebases are
almost ready to move out, that will probably happen for 4.17-rc1 if all
goes well.
Other than that, there is a bunch of license header cleanups in the
tree, along with the normal amount of coding style churn that we all
know and love for this codebase. I also got frustrated at the
Meltdown/Spectre mess and took it out on the dgnc tty driver, deleting
huge chunks of it that were never even being used.
Full details of everything is in the shortlog.
All of these patches have been in linux-next for a while with no
reported issues.

Note there is a misc driver drop in here given we have support
in IIO and the feeling is no one will care.
A large part of this series is a boiler plate removal series avoiding
the need to explicitly provide THIS_MODULE in various locations.
It's very dull but touches all drivers.
New device support
* ad5446
- add ids to support compatible parts DAC081S101, DAC101S101,
DAC121S101.
- add the dac7512 id and drop the misc driver as feeling is no
one is using it (was introduced for a board that is long obsolete)
* mt6577
- add bindings for mt2712 which is fully compatible with other
supported parts.
* st_pressure
- add support for LPS33HW and LPS35HW with bindings (ids mostly).
New features
* ccs811
- Add support for the data ready trigger.
* mma8452
- remove artifical restriction on supporting multiple event types
at the same time.
* tcs3472
- support out of threshold events
Core and tree wide cleanup
* Use macro magic to remove the need to provide THIS_MODULE as part of
struct iio_info or struct iio_trigger_ops. This is similar to
work done in a number of other subsystems (e.g. i2c, spi).
All drivers are fixed and then the fields in these structures are
removed.
This will cause build failures for out of tree drivers and any
new drivers that cross with this work going into the kernel.
Note mostly done with a coccinelle patch, included in the series
on the mailing list but not merged as the fields no longer exist
in the structures so the any hold outs will cause a build failure.
Cleanups
* ads1015
- avoid writing config register when it doesn't change.
- add 10% to conversion wait time as it seems it is sometimes
a little small.
* ade7753
- replace use of core mlock with a local lock. This is part of a
long term effort to make the use of mlock opaque and single
purpose.
* ade7759
- expand the use of buf_lock to cover previous mlock cases. This
is a slightly nicer solution to the same issue as in ade7753.
* cros_ec
- drop an unused variable
* inv_mpu6050
- add a missing break in a switch for consistency - not actual
bug,
- make some local arrays static to save on object code size.
* max5481
- drop manual setting of the spi module owner as handled by the
spi core.
* max5487
- drop manual setting of the spi module owner as handled by the
spi core.
* max9611
- drop explicit setting of the i2c module owner as handled by
the i2c core.
* mcp320x
- speed up reads on single channel devices,
- drop unused of_device_id data elements,
- document the struct mcp320x,
- improve binding docs to reflect restrictions on spi setup and
to make it explicit that the reference regulator is needed.
* mma8452
- symbolic to octal permissions,
- unsigned to unsigned int.
* st_lsm6dsx
- avoid setting odr values multiple times,
- drop config of LIR as it is only ever set to the existing
defaults,
- drop rounding configuration as it only ever matches the defaults.
* ti-ads8688
- drop manual setting of the spi module owner as handled by the
spi core.
* tsl2x7x
- constify the i2c_device_id,
- cleanup limit checks to avoid static checker warnings (and generally
have nicer code).

- drop an unused variable
* inv_mpu6050
- add a missing break in a switch for consistency - not actual
bug,
- make some local arrays static to save on object code size.
* max5481
- drop manual setting of the spi module owner as handled by the
spi core.
* max5487
- drop manual setting of the spi module owner as handled by the
spi core.
* max9611
- drop explicit setting of the i2c module owner as handled by
the i2c core.
* mcp320x
- speed up reads on single channel devices,
- drop unused of_device_id data elements,
- document the struct mcp320x,
- improve binding docs to reflect restrictions on spi setup and
to make it explicit that the reference regulator is needed.
* mma8452
- symbolic to octal permissions,
- unsigned to unsigned int.
* st_lsm6dsx
- avoid setting odr values multiple times,
- drop config of LIR as it is only ever set to the existing
defaults,
- drop rounding configuration as it only ever matches the defaults.
* ti-ads8688
- drop manual setting of the spi module owner as handled by the
spi core.
* tsl2x7x
- constify the i2c_device_id,
- cleanup limit checks to avoid static checker warnings (and generally
have nicer code).
The commit adds mt2712 compatible node in binding document.

All chips supported by this driver clock data out on the falling edge
and latch data in on the rising edge, hence SPI mode (0,0) or (1,1)
must be used.
Furthermore, none of the chips has an internal reference voltage
regulator, so an external supply is always required and needs to be
specified in the device tree lest the IIO "scale" in sysfs cannot be
calculated.
Document these requirements in the device tree binding, add compatible
strings for the newly supported mcp3550/1/3 and explain that SPI mode
(0,0) should be preferred for these chips.

STM32 ADC allows each channel to be sampled with a different sampling
time. There's an application note that deals with this: 'How to get
the best ADC accuracy in STM32...' It basically depends on analog input
signal electrical properties (depends on board).
Add optional 'st,min-sample-time-nsecs' property so this can be tuned
in dt.

4 completely new drivers in this set and plenty of other stuff.
One ABI change due to a silly mistake a long time back. Hopefully no
one will notice. It effects the numerical order of consumer device
channels which was the reverse of the obvious. It's going the slow
way to allow us some margin to spot if we have broken userspace or
not (seems unlikely)

Here is the "big" char/misc driver patchset for 4.13-rc1.
Lots of stuff in here, a large thunderbolt update, w1 driver header
reorg, the new mux driver subsystem, google firmware driver updates, and
a raft of other smaller things. Full details in the shortlog.
All of these have been in linux-next for a while with the only reported
issue being a merge problem with this tree and the jc-docs tree in the

happens, if not, we can send a follow-up patch for it afterward.

This is an upstream port of an IIO driver for the TI ADC108S102 and
ADC128S102. The former can be found on the Intel Galileo Gen2 and the
Siemens SIMATIC IOT2000. For those boards, ACPI-based enumeration is
included.
Due to the lack of regulators under ACPI, we hard-code the voltage
provided to the VA pin of the ADC to 5 V, the value used on Galileo and
IOT2000. For DT usage, the regulator "vref-supply" provides this
information. Note that DT usage has not been tested.

Here is the big staging tree update for 4.12-rc1. And it's a big one,
adding about 350k new lines of crap^Wcode, mostly all in a big dump of
media drivers from Intel. But there's other new drivers in here as
well, yet-another-wifi driver, new IIO drivers, and a new crypto
accelerator. We also deleted a bunch of stuff, mostly in patch
cleanups, but also the Android ION code has shrunk a lot, and the
Android low memory killer driver was finally deleted, much to the
celebration of the -mm developers.
All of these have been in linux-next with a few build issues that will
show up when you merge to your tree, I'll follow up with fixes for those
after this gets merged.

This adds max1117/max1118/max1119 8-bit, dual-channel ADC driver.
This new driver uses the zero length spi_transfers with the cs_change
flag set and/or the non-zero delay_usecs.
1. The zero length transfer with the spi_transfer.cs_change set is
required in order to select CH1. The chip select line must be brought
high and low again without transfer.
2. The zero length transfer with the spi_transfer.delay_usecs > 0 is
required for waiting the conversion to be complete. The conversion
begins with the falling edge of the chip select. During the conversion
process, SCLK is ignored.
These two usages are unusual. But the spi controller drivers that use
a default implementation of transfer_one_message() are likely to work.
(I've tested this adc driver with spi-omap2-mcspi and spi-xilinx)
On the other hand, some spi controller drivers that have their own
transfer_one_message() may not work. But at least for the zero length
transfer with delay_usecs > 0, I'm proposing a new testcase for the
spi-loopback-test that can test whether the delay_usecs setting has
taken effect.

In order to accommodate in a logical manner for the premuxed channels
in PM8921 and the similarly addressed channels in later PMICs, we
need a twocell arrangement with premux and analog mux setting as
a tuple to uniquely identify a hardware channel.
These bindings are not yet in use, so it should be fine to augment
them before we actually start using it in drivers and device trees.
This scheme came out of lengthy discussions and reverse-engineering
and reading of the few information sources we have.

The mpu9250 is a SIP containing an mpu6500 and an ak8975. If this was all
there was too it there would be no need for explicit handling in the driver.
Arguably the bindings would also only reflect the presence of an mpu6500 with
the ak8975 hanging off it, as the kernel doesn't care that they are in one
package.
However, the WHOAMI value changes as well so best to add explicit support.

On Motorola phones like droid 4 there is a custom CPCAP PMIC. This PMIC
has ADCs that are used for battery charging and USB PHY VBUS and ID pin
detection.
Unfortunately the only documentation for this ADC seems to be the
Motorola mapphone Linux kernel tree. I have tested that reading raw and
scaled values works, but I have not used the timed sampling that the ADC
seems to support.
Let's add a minimal support for it so we can eventually provide IIO
channels for the related battery charging and USB PHY drivers.

Device tree contents continue to be the largest branches we submit. This
time around, some of the contents worth pointing out is:
- New SoC platforms:
- Freescale i.MX 7Solo
- Broadcom BCM23550
- Cirrus Logic EP7209 and EP7211 (clps711x platforms)_
- Hisilicon HI3519
- Renesas R8A7792
Some of the other delta that is sticking out, line-count wise:
- Exynos moves of IP blocks under an SoC bus, which causes a large delta due
to indentation changes
- A new Tegra K1 board: Apalis
- A bunch of small updates to many Allwinner platforms; new hardware support,
some cleanup, etc.

Some types of ST Sensors can be connected to the same IRQ line
as other peripherals using open drain. Add a device tree binding
and a sensor data property to flip the right bit in the interrupt
control register to enable open drain mode on the INT line.
If the line is set to be open drain, also tag on IRQF_SHARED
to the IRQ flags when requesting the interrupt, as the whole
point of using open drain interrupt lines is to share them with
more than one peripheral (wire-or).

* mma8452
- FXLS8471Q support
- NXP LPC18XX SOC ADC

- NXP LPC18XX SOC DAC
- new driver.
- rockchip_saradc
- support rk3399
* st accel
- h3lis331dl support
Staging driver removals
* adis16204
- obsolete part making it hard to get parts to test the driver in order
to clean it up.
* adis16220
- obsolete part making it hard to get the parts test the driver in order
to clean it up.
Features
* core
- convenience functions to claim / release direct access to the device.
Makes more consistent handling of this corner easier. Used in ad7192 driver.
* ak8975
- power regulator support.
* at91-sama5d2
- differential channel support.
* mma8452
- runtime pm support
- drop device specific autosleep and use the runtime pm one instead.
* ms5611
- DT bindings
- oversampling ratio support
Cleanups and minor fixes
* MAINTAINERS
- Peter got married - hence name change!
* Documentation
- Fix a typo in in_proximity_raw description.
- Add some missing docs for iio_buffer_access_funcs.
* Tools
- update iio_event_monitor names to match new stuff.
- make generic_buffer look for triggers ending in -trigger as we let these in
for a number of drivers a long time back and now it is a fairly common
option.
Drivers
* staging wide
- convert bare unsigned usage to unsigned int to comply with coding style.
* non staging wide:
- since boiler plate gpio handling of interrupts has been moved into the
ACPI core we don't need to include gpio/consumer.h in a load of drivers so
drop it.
* ad7606
- fix an endian casting sparse warning.
* ak8975
- fix a possible unitialized warning from gcc.
- drop and unused field left over from earlier cleanups
- fix a missing regulator_disable on exit.
* at91-sama5d2
- typo and indentation
- missing IOMEM dependency.
- cleanup mode register usage by avoidling erasing whole thing when changing
the sampling frequency.
* bmc150
- use the core demux and available_scan_masks to simplify buffer handling
- optimize the transfers in the trigger handler now we have a magic function
to emulate bulk reads (under circumstances met here). This matters with some
rather dumb i2c adapters in particular.
- use a single regmap_conf for all bus types as they were all the same.
* bmg160
- use the core demux and available_scan_masks to simplify the buffer handling
- optimize the transfers in the trigger handler now we have a magic funciton
to emulate bulk rads (under circumstances met here).
- drop gpio interrupt probing from the driver (ACPI) as now handled by the
ACPI core.
* ina2xx-adc
- update the CALIB register when RShunt changes.
- fix scale for VShunt - in reality this error canceled out when used.
* isl29028
- use regmap to retrieve the struct device instead of carrying a second
copy of it around.
* kxcjk-1013
- use core demux
- optimize i2c transfers in the trigger handler.
* mcp4531
- refactor to use a pointer to access model parameters instead of indexing
into the array each time.
* mma8452
- style fixes
- avoid swtiching to active whenever the config changes
- add missin i2c_device_id for mma8451
* mpu6050
- fix possible NULL dereference.
- fix the name / chip_id used when ACPI used (otherwise reports as NULL).
* ms5611
- fix a missing regulator_disable that left the regulator on during removal.
* mxc4005
- drop gpio interrupt handling for ACPI case from driver as the core now
handles this case.
* st-sensors
- note that there are only ever a maximum of 3 axis on current st-sensors
so just allocate a fixed sized buffer big enough for that.
* tpl0102
- change the i2c_check_functionality condition to bring it inline with other
IIO users as EOPNOTSUPP.
* tsl2563
- replace deprecated flush_scheduled_work

Features
* core
- convenience functions to claim / release direct access to the device.
Makes more consistent handling of this corner easier. Used in ad7192 driver.
* ak8975
- power regulator support.
* at91-sama5d2
- differential channel support.
* mma8452
- runtime pm support
- drop device specific autosleep and use the runtime pm one instead.
* ms5611
- DT bindings
- oversampling ratio support
Cleanups and minor fixes
* MAINTAINERS
- Peter got married - hence name change!
* Documentation
- Fix a typo in in_proximity_raw description.
- Add some missing docs for iio_buffer_access_funcs.
* Tools
- update iio_event_monitor names to match new stuff.
- make generic_buffer look for triggers ending in -trigger as we let these in
for a number of drivers a long time back and now it is a fairly common
option.
Drivers
* staging wide
- convert bare unsigned usage to unsigned int to comply with coding style.
* non staging wide:
- since boiler plate gpio handling of interrupts has been moved into the
ACPI core we don't need to include gpio/consumer.h in a load of drivers so
drop it.
* ad7606
- fix an endian casting sparse warning.
* ak8975
- fix a possible unitialized warning from gcc.
- drop and unused field left over from earlier cleanups
- fix a missing regulator_disable on exit.
* at91-sama5d2
- typo and indentation
- missing IOMEM dependency.
- cleanup mode register usage by avoidling erasing whole thing when changing
the sampling frequency.
* bmc150
- use the core demux and available_scan_masks to simplify buffer handling
- optimize the transfers in the trigger handler now we have a magic function
to emulate bulk reads (under circumstances met here). This matters with some
rather dumb i2c adapters in particular.
- use a single regmap_conf for all bus types as they were all the same.
* bmg160
- use the core demux and available_scan_masks to simplify the buffer handling
- optimize the transfers in the trigger handler now we have a magic funciton
to emulate bulk rads (under circumstances met here).
- drop gpio interrupt probing from the driver (ACPI) as now handled by the
ACPI core.
* ina2xx-adc
- update the CALIB register when RShunt changes.
- fix scale for VShunt - in reality this error canceled out when used.
* isl29028
- use regmap to retrieve the struct device instead of carrying a second
copy of it around.
* kxcjk-1013
- use core demux
- optimize i2c transfers in the trigger handler.
* mcp4531
- refactor to use a pointer to access model parameters instead of indexing
into the array each time.
* mma8452
- style fixes
- avoid swtiching to active whenever the config changes
- add missin i2c_device_id for mma8451
* mpu6050
- fix possible NULL dereference.
- fix the name / chip_id used when ACPI used (otherwise reports as NULL).
* ms5611
- fix a missing regulator_disable that left the regulator on during removal.
* mxc4005
- drop gpio interrupt handling for ACPI case from driver as the core now
handles this case.
* st-sensors
- note that there are only ever a maximum of 3 axis on current st-sensors
so just allocate a fixed sized buffer big enough for that.
* tpl0102
- change the i2c_check_functionality condition to bring it inline with other
IIO users as EOPNOTSUPP.
* tsl2563
- replace deprecated flush_scheduled_work
The following functionalities are supported:
- write, read from volatile memory

Usual mixed bag, but the big item perhaps in this series is the DMA buffer
support added by Lars-Peter Clausen. It's been in the works for a long time
and it will be interesting to see what hardware support shows up now that
this is available.
New core features + associate cleanup.
* Add generic DMA buffer infrastructure
* Add a DMAengine framework based buffer
Also associated minor changes.
- Set the device buffer watermark based on the minimum watermark for all
attached buffers rather than just the 'primary' one.
- iio_buffer_init - only set the watermark default if one hasn't already
been provided. This allows simple support for devices with a fixed
watermark.
- read only attribute for watermark on fixed watermark devices.
- add explicit buffer enable/disable callbacks to allow the buffer to
do more than trivial actions when it is being turned on and off.
* IIO_VAL_INT support in write_raw_get_fmt function.
New device support
* Freescale MMA7455/7456L accelerometers
* Memsic MXC6255XC accelerometer
* ST lis2dh12 accelerometer
* TI ADS8688 ADC
* TI Palamas (twl6035/7) gpadc
New driver features
* mma8452
- support either of the available interrupt pins to cope with the case
where board layout has lead to a particular one being connected.
Staging graduation
* Dummy driver
- this driver acts as both an example and a test device for those with
out hardware to develop userspace code against.
Cleanups and minor bits and bobs.
* treewide
- Sort out the ordering of iio_device_register/unregister vs runtime
pm function calls so that it's all nice and consistent and not race
prone.
- Check sscanf return values. None of the cases will actually happen as
the strings are supplied internally, but best to be consistent on this.
* ad7780
- switch over to the gpio descriptor interface and remove the now unused
platform data which gets rid of a header entirely.
* ad7793
- drop a pointless else statement.
* at91_adc
- Swap kmalloc_array in for a kmalloc doing the same job.

The Microchip Analog to Digital Converter (ADC) Device Tree binding
documents compatible strings with no vendor prefix. Since it should
compatible strings with also a vendor, add these to the binding doc
and mark the old ones as deprecated.
The driver says that the device is from Microchip Technology which
is listed in Documentation/devicetree/bindings/vendor-prefixes.txt
so use the documented prefix.

This change is important in order for everyone to be easily able to use the
driver for one of the supported accelerometer chips!
Until now, the driver blindly assumed that the INT1 interrupt line is wired
on a user's board. But these devices have 2 interrupt lines and can route
their interrupt sources to one of them. Now, if "INT2" is found and matches
i2c_client->irq, INT2 will be used.
The chip's default actually is INT2, which is why probably many boards will
have it wired and can make use of this.
Of course, this also falls back to assuming INT1, so for existing users
nothing will break. The new functionality is described in the bindings doc.

MMA8652FC and MMA8653FC don't provide the transient interrupt source, so
the motion interrupt source is used by providing a new iio_chan_spec

The bma180 / bma250 accelerometers share a driver (at least under Linux),
so it makes sense to also have their bindings info in a single .txt.
This commit extends the bma180 bindings with bma250 bindings, specifically
it specifies how the 2 seperate interrupts the bma250 has must be listed
in devicetree. The existing bma180 driver is already fully compatible
with the specified bindings.

The driver currently does not take into account the minimum sample time
as per the Figure 6-8 Chapter 9.1.1 12-bit ADC electrical characteristics.
We set a static amount of cycles instead of considering the sample time
as a given value, which depends on hardware characteristics.
Determine sampling frequencies by first reading the device tree property
node and then calculating the required Long Sample Time Adder (LSTAdder)
value, based on the ADC clock frequency and sample time value obtained
from the device tree. This LSTAdder value is then used for calculating
the sampling frequencies possible.
In case the sample time property is not specified through the device
tree, a safe default value of 1000ns is assumed.

Here's the big staging driver patchset for 4.1-rc1.
There's a lot of patches here, the Outreachy application period happened
during this development cycle, so that means that there was a lot of
cleanup patches accepted. Other than the normal coding style and sparse
fixes here, there are some driver updates and work toward making some of
the drivers into "mergable" shape (like the Unisys drivers.)
All of these have been in linux-next for a while.

Add support for system sleep and runtime power management.
To wake up the device, the SDA line should be held low for at least 33ms
while SCL is high. As this is not possible using the i2c API (and not
supported by all i2c adapters), a GPIO connected to the SDA line is
needed. The GPIO is named "wakeup" and can be specified in a device
tree with the "wakeup-gpios" binding.
If the wake-up GPIO is not given, disable power management for the
device. Entering sleep requires an SMBus byte access, hence power
management is also disabled if byte access is not supported by the
adapter.

New drivers
* CM3323 color sensor.
* MS5611 pressure and temperature sensor.
New functionality
* mup6050 - create mux clients for devices described via ACPI. The reasoning
and approach taken in this patch are complex. Basically there is no
otherway of finding out what is there than by some esoteric look ups in
the ACPI data.
* cm3232 - PM support
* itg3200 - suspend/resume support
* mcp320x - add more ADCs to the kconfig to reflect what the driver supports
(this patch and the bindings got left behind when the support was added
a while back).
Docs / utils
* ti-adc128s052 - DT bindings.
* mcp3422 - DT bindings.
* mcp320x - DT bindings
* ABI docs for event threshold scale attributes, in_magn_offset, proximity

* Tidy up the tools previously in drivers/staging/iio/Documentation and move
them out to /tools/iio. Yet another move that should have happened long ago.
This time Roberta Dobrescu did the leg work. Thanks!
Core Cleanups
* Export userspace IIO headers. We should have done the appropriate header
splitting a long time ago. Thanks to Daniel for sorting this out.
* Refactor the registring of attributes for buffers to move all non-custom
ones to a vector allowing easier additions to the current set in the future.
Driver Cleanups
* gpiod related cleanups. Make use of the additional parameter to specify
initial direciton to avoid extra code.
* bmc150 - Various refactorings to reduce code repitition and prepare for
hardware buffer support. Some of these cleanups are good even
without the new functionality.

was always the index to an element in an array of that structure.

Here's the big staging driver tree update for 3.20-rc1. Lots of little
things in here, adding up to lots of overall cleanups. The IIO driver
updates are also in here as they cross the staging tree boundry a lot.
I2O has moved into staging as well, as a plan to drop it from the tree
eventually as that's a dead subsystem.

Once again, we are deleting more code than we added, with something like
150000 lines deleted overall. Some of this is due to drivers being
added to the networking tree, so the old versions are removed here, but
even then, the overall difference is quite good.
Other than driver deletions, lots and lots and lots of minor cleanups

Older Rockchip SoCs, at least the rk3066, used a slightly modified saradc
for temperature measurements. This so called tsadc does not contain any
active parts like temperature interrupts and only supports polling the
current temperature. The returned voltage can then be converted by a
suitable thermal driver to and actual temperature and used for thermal
handling.

Merge tag 'iio-for-3.16a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First round of IIO new driver, functionality and cleanups for the 3.16 cycle.
New device support
* AS3935 Lightning Sensor
* MCP3426/7/8 support added to the existing MCP3422 ADC driver
* AK8963 support in the AK8975 driver
* MPU6500 support in the MPU6050 driver (the functionality that is different
is mostly not supported yet in either part).
Staging Graduations
* AD799x ADC
New functionality
* ACPI enumeration for the ak8975 driver
Cleanup / tweaks
* Use snprintf as a matter of good practice in a few additional places.
* Document *_mean_raw attributes. These have been there a while, but were
undocumented.
* Add an in kernel interface to get the mean values.
* Bug in the length of the event info mask that by coincidence wasn't yet
actually causing any problems.
* itg3000 drop an unreachable return statement.
* spear_adc cleanups (heading for a staging graduation but a few more
issues showed up in the review of these patches).
* Exynos ADC dependencies changed so it is only built when Exynos is present
or COMPILE_TEST and OF are set.
* tsl2583 cleanups.
* Some cut and paste typos in the comments of various drivers still in staging.
* Couple of minor improvements to the ST sensor drivers.
A large part of the arm-soc patches are nowadays DT changes, adding support
for new SoCs, boards and devices without changing kernel source. The plan
is still to move the devicetree files out of the kernel tree and reduce
the amount of churn going on here, but we keep finding reasons to delay
doing that.
Changes are really all over the place, with little sticking out particularly.
We have contributions from a total of 116 people in this branch.
Unfortunately, the size of this branch also causes a significant number
of conflicts at the moment, typically when subsystem maintainers merge
patches that change the driver at the same time as the dts files. In
most cases this could be avoided because the dts changes are supposed
to be compatible in both ways, and we are asking everyone to send ARM
dts changes through our tree only.

The Xilinx XADC is a ADC that can be found in the series 7 FPGAs from Xilinx.
The XADC has a DRP interface for communication. Currently two different
frontends for the DRP interface exist. One that is only available on the ZYNQ
family as a hardmacro in the SoC portion of the ZYNQ. The other one is available
on all series 7 platforms and is a softmacro with a AXI interface. This binding
document describes the bindings for both of them since the bindings are very
similar.
Each of them needs:
* A address range where the registers are mapped
* An interrupt number for the device interrupt
* A clock. For the the ZYNQ hardmacro interface this is the modules PCAP
clock, for the AXI softmacro it is the AXI bus interface clock.
Additionally the bindings specify whether an external multiplexer is used and in
which mode it is used. The devicetree bindings also describe which external
channels are connected and in which configuration.
