The I2C directory is for I2C master controllers, not for clients. So,
move the file describing trivial devices one layer upwards where it
fits its generic nature way better.

Pull powerpc updates from Michael Ellerman:
"Highlights include:
- Support for the kexec_file_load() syscall, which is a prereq for
secure and trusted boot.
- Prevent kernel execution of userspace on P9 Radix (similar to
SMEP/PXN).
- Sort the exception tables at build time, to save time at boot, and
store them as relative offsets to save space in the kernel image &
memory.
- Allow building the kernel with thin archives, which should allow us
to build an allyesconfig once some other fixes land.
- Build fixes to allow us to correctly rebuild when changing the
kernel endian from big to little or vice versa.
- Plumbing so that we can avoid doing a full mm TLB flush on P9
Radix.
- Initial stack protector support (-fstack-protector).
- Support for dumping the radix (aka. Linux) and hash page tables via
debugfs.
- Fix an oops in cxl coredump generation when cxl_get_fd() is used.
- Freescale updates from Scott: "Highlights include 8xx hugepage
support, qbman fixes/cleanup, device tree updates, and some misc
cleanup."
- Many and varied fixes and minor enhancements as always.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First round of IIO new device support, features and cleanups for the 4.10 cycle.
Fair number of outreachy related patches in here. Some of these may well
have already been picked up by Greg but git will sort that out for us.
Also some good staging cleanup work from other sources. Thanks Brian and Lars
in particular for this.
New device support
* ACCES 104-quad-8
- New driver for this 8 channel encoder input board. Lots of new ABI with
this one.
* AD7766
- New driver supporting AD7766, AD7766-1, AD7766-2, AD7767, AD7767-1 and
AD7767-2 24 bit ADCs.
* dmard 10
- New driver for this 3 axis accelerometer.
* Honeywell ABP pressure sensors.
- New driver covering 56 parts in this series (too many to list here!)
* HTS221
- New driver to support this relative humidiy and temperature device.
* LMP91000
- New driver for this potentiostat (form of chemical sensor). Nice example
of use of the buffered consumer interfaces and the use of a consumer
provided trigger.
* MiraMEMS DA311
- New driver for this 3 axis accelerometer.
* MiraMEMS DA280
- New driver for this 3 axis accelerometer. Follow up caught up with
vendor prefixes for these.
Staging graduations
* isl29018 light sensor
- Fixes and cleanups listed below (thanks for your hard work on this Brian!)
* sca3000
- Fixes and cleanups listed below. This was one of the small set of drivers
that went into staging when IIO was first added. Turns out it had a few
bugs and needed to be brought into the modern era! Not clear if I am
the only person who actually has one of these still wired to a board.
New features (Core)
- Add an iio_trigger_validate_own_device helper which relies on the device
and trigger having the same parent. Convenient to have this for some
of the more complex trigger / device interactions. Was hand rolled in
a few drivers already so good to bring it into the core.
- Add an iio_read_channel_offset in kernel access helper (similar to
the existing one for scale).
- IIO_ATTR_{RO, WO, RW} and IIO_DEVICE_ATTR_{RO, WO, RW} macros. These
lead some rather contrived function naming, but there is no denying they
do reduced boilerplate. I'm going to resist their introduction in
drivers 'unless' they form part of a larger set of cleanups.
- Counter channel type and index type.
New features (Drivers)
* hdc100x
- Triggered buffer support.
* mcp4725
- Device tree bindings and support.
- Voltage reference selection.
* ti-adc0832
- Triggered buffer support.
* ti-adc161s626
- Add regulator support allowing _scale and _offset values to be established
and exported.
New features (Tools)
* iio_generic_buffer
- -A option to force enable all channels rather than faulting if some are
already enabled (like -a does). Followup patches tidied this support up.
Cleanups (Core)
- Use kmalloc_array in iio_scan_mask_set.
- Take event_attrs field of iio_info structure constant
- Staging todo list updates. Most of it was long done.
- MAINTAINERS had a wrong directory listing.
Cleanups (Drivers)
* Missing i2c trivial devices entries.
* ad5592r
- Fix an endian type related sparse warnings.
* ad7150
- Constify the event attribute_group structures.
* ad7152
- Add some blank lines to improve readability.
- Sampling frequency control via chan-info element rather than hand rolled
attributes.
- add a new lock to avoid use of mlock for non state change related locking.
* ad7280
- Constify atrribute_group structure (second patch covers the event ones)
* ad7606 (Lars is driving most of the cleanup on this with some additions from
Eva)
- Fix improper setting of oversampling pins. This has been broken a very
long time in this staging driver, so not going to push this back to stable.
- Implement oversampling configuration via the chan_info mask element.
- Remove an unused int_vref_mv field.
- Remove a reundant name field from ad7606_chip_info.
- Remove default device configuration from platform_data in favour of
whatever the power on defaults are.
- Remove out of band error reporting in the kernel log as not providing
much information.
- Fix oversampling ratio by having 1 be the value for no oversampling.
- Avoid allocating buffer for each data capture.
- Factor out common code between periodic and one-shot capture.
- Move set_drvdat into common code.
- Let the common probe function return int rather than jumping through
an ERR_PTR.
- Pass struct device * into common remove to simplify code.
- Always run trigger handler only once per event (no one can remember why
it was being possibly done twice).
- Move over to the GPIO descriptor API to shorten and clarify code.
- Move the buffer code into the main file as it's not optional and is
now rather short in this driver.
- Fix the naming of the supply regulator.
- Rework regulator handling to handle errors including deferred probing.
- Tidy up a ptr_err or 0 return.
* ad7746
- Sampling frequency control via info_mask element rather than hand rolled
* ad7758
- Sampling frequency control via info_mask element rather than hand rolled
attributes.
* ad7816
- Constify the event attribute_group structure.
* adt7316
- Constify the event attribute group structures.
* ak8974
- Cleanup some sparse warnings about endian types.
* ak8975
- Cleanup some sparse warnings about endian types.
* bmi160
- Spare endian warning cleanups.
* isl29018 (towards staging graduation)
- Remove unusedvariables and defines.
- Improve consistency of error handling.
- Signed / unsigned comparison fixes.
- Use the IIO_DEVICE_ATTR_{RO, RW} macros
- Fix a race in in_illuminance_scale_available_show.
- Cleanup exit points of _read_raw
- Sanity check if in suspended state during a write_raw call as was already
done for read_raw.
- Document device tree bidnings.
- Document infrared supression controls.
- Add some newlines to improve readability and drop one that shouldn't be
there.
- Fix a poorly named functions name.
- Fix multiline coment syntax.
- Tidy up a pair or return statements by unifying them.
- Rename description in Kconfig for consistency with similar drivers.
* lidar
- cleanup power management by dropping unnecessary call.
* ltr501
- Use the claim_direct_mode helpers. Fix a race condition along the way.
* max1027
- Fix a dubious x | !y sparse warning.
- Use the new iio_trigger_validate_own_device helper.
* max440000
- Clean up some sparse warnings about endian types.
* mcp4725
- Use the regulator framework to establish the reference voltage rather than
getting it from platform data.
- Tidy up a comment typo.
- Fix a wrong PTR_ERR query (wrong regulator).
* mma7660
- Take a mma7660_nscale static.
* mma8452
- Use the new iio_trigger_validate_own_device helper.
- Use claim_direct_mode helpers - fix a race condition along the way.
* mpl3115
- Use claim_direct_mode helpers - fix a race condition along the way.
* ms65611
- Tidy up regulator error handling and clean out a static warning in the mix.
* sca3000
- Avoid a potential unitialized variable if a hardware read returns a value
that isn't actually supported (mostly warning supression).
- Fix a use before setting of the indio_dev->buffer pointer. Broken for
a very long time so not going to rush this into stable.
- Merge buffer file with core file. We used to always split these.
Sometimes it's just not worth the hassle. In this case the device's main
feature is it's hardware fifos so unlikely anyone would want to run it
without.
- Drop the sca3000_register_ring_funcs function as it's a pointless wrapper
once we have only one file.
- Fix cleaning of flag + setting of size of scan. Without this you can't
start the buffer twice and expect sensible (or any) results. Again,
broken for a long time so not heading for stable.
- Drop the custom watershed setting ABI - for now we'll just support one
value.
- Move to a hybrid hard / soft buffer design (how we've been doing it
for similar devices for a while now!)
- Cleanup some unusued variables.
- Use a fake channel to support core handling of freefall event registration.
- Cleanup the register defines.
- Fix an off by one error in axis due to IIO_NO_MOD taking up the 0 value.
Been broken since first admission of IIO to the staging tree.
- Add readback of the 3db low pass filter frequency and later writing
allowing droppign of custom measurement mode attributes as they can
be represented by the filter choices that is their main characteristic.
- Drop non standard revision attr and replace with dev_info on probe.
- Avoid a race in probe.
- Various formatting fixes.
- Kernel-docify docs that were very nearly in the write format.
* tsl2583
- Constify attribute_group structure.
* zpa2326
- Drop a redundant DEBUG ifdef.
Cleanups (Tools)
* iio_generic_buffer
- Fix the ? arguement. Previously it sort of worked as you got the help
message as a result of it not recognising the arguement.

Jonathan writes:
First round of new features, device support and cleanups for IIO in the 4.9 cycle.
Device support
* ak8974
- New driver and bindings for this 2009 vintage magnetometer (it was very
popular back then!)
* atlas-ph-sensor
- ORP sensor support(I had to look up what one of these was)
* cio-dac
- New driver for Measurement Computing DAC boards
* dmard06
- New driver for Domintech DMARDO6 accelerometer. Also vendor prefix.
* dmard09
- New driver for Domintech DMARD09 accelerometer.
* maxim-thermocouple
- max6675 and max31855 new driver
* mt6577 auxdac
- new driver for this Mediatek chip mt2701, mt6577 and mt8173 have this
hardware.
* ti-adc161s626
- new driver for this TI single channel differential ADC.
* vcnl4000
- support vcnl4010 and vcnl4020 which are compatible for all features
currently supported by this driver.
New features
* Core
- Allow retrieving of underlying iio_dev from a callback buffer handle.
This is needed to allow client drivers to perform operations such as
configuring the trigger used.
* hid-sensors
- asynchronous resume support to avoid really long resume times.
* kxcjk-1013
- add the mysterious KIOX000A ACPI id seen in the wild.
* Tools
- lsiio now enumerates processed as well as raw channels.
Cleanup
* ad7298
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* ad7793
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* ade7854
- checkpatch fixups (alignment of parameters)
* atlas-ph-sensor
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
- Switch to REGCACHE_NONE as there are no useful register to cache.
* bma180
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* hdc100x
- Add mention of the HDC1000 and HDC1008 to the Kconfig help text.
* isl29018
- Add driver specific prefixes to defines and function names.
- Remove excessive logging.
- Drop newlines which add nothing to readability.
- General tidying up of comments.
- Drop I2C_CLASS_HWMON as irrelevant to driver.
* isl29028
- Add driver specific prefixes to defines, enums and function names.
- Drop comma's from available attribute output as not ABI compliant.
- Drop I2C_CLASS_HWMON as irrelevant to driver.
* kxsd9
- devicetree bindings.
* mag3110
- This one wasn't locking to protect against mode switches during
raw_reads. Use the iio_claim_direct_mode function to fix this buglet.
* maxim-theromcouple
- Fix missing selects for triggered buffer support in Kconfig.
* nau7802
- Use complete instead of complete_all as only one completion at a time.
* sx9500
- Use complete instead of complete_all as only one completion at a time.
* us5182d
- Add a missing error code asignment instead of checking the result of
an already checked statement.
* vcnl4000
- Use BIT macro where appropriate.
- Refactor return codes in read_raw callback.
- Add some missing locking for concurrent accesses to the device.

The documentation currently uses the non-standard vendor prefix stm
and st-micro for STMicroelectronics. The drivers do not specify the
vendor prefixes since the I2C Core strips them away from the DT
provided compatible string. Therefor, changing documentation and
existing device trees does not have any impact on device detection.

told to enable TPM2 mode when the compatible string indicates a

Pull i2c updates from Wolfram Sang:
"Quite some driver updates:
- piix4 can now handle multiplexed adapters
- brcmstb, xlr, eg20t, designware drivers support more SoCs
- emev2 gained i2c slave support
- img-scb and rcar got bigger refactoring to remove issues

- new quirk flag when an adapter does not support clock stretching,
so clients can be configured to avoid that if possible
- added a helper function to retrieve timing parameters from firmware
(with rcar being the first user)

setting (like disabling PM to keep arbitration working)
- RuntimePM for the logical adapter device is now always enabled by
the core to ensure propagation from childs to the parent (the HW
device)

EEPROMs can have additional properties, so they are not suitable for
trivial-devices.txt. Move most bindings to the designated eeprom.txt.
Add the missing "atmel,24c08" while doing that. Note that the remaining
ones in trivial-devices need to be dealt with separately because of
improper manufacturer names.

First round of new driver, new functionality and cleanups for IIO in the 4.4 cycle
New device support
* APDS9960 ALS + proximity driver
* bmg160 SPI devices.
* HDC100x humidity sensors
* Holt HI-8435 threshold detector
* mma8453Q accelerometer added to the mma8452 driver
* mma86452FC and mma8653FC accelerometers added to the mma8452 driver
* mxc4005 accelerometer
* PulsedLight LIDAR
* SensorTech VZ89x volatile organic compound sensor
* UPISEMI uS5182d ALS and proximity sensors
New core functionality
* triggered events - use triggers to check for changes in threshold type
detectors on devices with out interrupt support. First user is the holt
comparator.
* chemical concentration and resistance channel types.
New driver functionality
* vf610
- buffer support.
- followup coccinelle warning fix.
Core rework
* buffers
- break out callback buffer to own module.
- move buffer implementations to a new subdirectory
* percolate the error code form iio_event_getfd out to userspace
rather than giving a missleading error later on.
Cleanups
* adddac drivers
- use BIT macro where appropriate.
* meter drivers
- use BIT macro where appropriate.
* ad7303
- add an OF match table to line up with the binding docs.
* adc128s052
- add an OF match table to line up with the binding docs.
* adf4350
- add an OF match table to line up with the binding docs
* as3935
- add an OF match table to line up with the binding docs.
* berlin2-adc
- use GENMASK and BIT for masks
- prevent attempting to sample multiple channels at once by moving a
mutex scop
- coding style cleanups
* bmg150_magn
- kconfig sort order was wrong - fix it.
* bmg160
- use i2c regmap and drop all uses of i2c_client
- separate i2c and core driver
* cc10001_adc
- kconfig sort order was wrong - fix it.
* evgen (dummy driver helper module)
- move interrupt generation to irq_work to reduce differences between
the dummy driver and real hardware drivers.
* hmc5843
- set the name dynamically rather than to a fixed value for one of the
suported parts.
- export module alias information to allow autoprobing of module.
* lpc32xx
- on failure to get resource or irq return -ENXIO as uppose to -EBUSY
* max1027
- set .of_match_table to actually allow OF style matching.
* max5821
- add MODULE_DEVICE_TABLE for OF table.
* mma8452
- refactor to separate out chip specific data.
- add freefall / motion interrupt source for devices that do their
interrupts slightly differently.
- update copywrite notice.
- leave naming of events directory in sysfs to the core
* mcp320x
- set .of_match_table so that it can be use for OF style matching.
* mlx90614
- Implement filter configuration (note the datasheet changed as a result
of the driver reviews to include the values we needed ;)
* opt3001
- drop .owner field as assigned by platform driver core.
* si7020
- replace a bitmask on the humidity values with a more correct range
check.
* stk310
- improved error handling.
- use BIT macro where appropriate and use the resulting defines
instead of magic numbers in the code.
- fix indentation
* st-sensors
- add debugfs register read hook
* tsl4531
- fix error handling in check_id
* twl6030
- fix module autoload for OF
* iio-trig-sysfs
- document add and remove attribute
* trigger in staging
- code alignment fixes.
- braces on both branches of if statement if needed for one.
* xilinx-xadc
- push interrupts into hardirq context as there isn't much in them
any more and it avoids breaking PREEMPT_RT builds due to the use
of a spinlock between the hardirq and the thread.
Tools
* event-monitor
- report unsupported events. We keep expanding what can come from drivers
so give a helpful error if one turns up in an out of date userspace
program.
* generic-buffer
- helpful message about needing to enable a channel to start the buffer.

DT nodes should use the more specific adi,adxl345 and adi,adxl346
compatible values instead. As the ADXL346 is backward-compatible with
the ADXL345, ADXL346 nodes must list both adi,adxl346 and adi,adxl345,
in that order.

"The changes here belong to two main platforms:
- Atmel At91 is flipping the bit and going multiplatform. This
includes some cleanups and removal of code, and the final flip of
config dependencies
- Shmobile has several platforms that are going multiplatform, but
this branch also contains a bunch of cleanups that they weren't
able to keep separate in a good way. THere's also a removal of one
of their SoCs and the corresponding boards (sh7372 and mackerel)"

CM3232 is an advanced ambient light sensor with I2C protocol interface.
The I2C slave address is internally hardwired as 0x10 (7-bit). Writing
to configure register is byte mode, but reading ALS register requests to
use word mode for 16-bit resolution.

This patch adds support for Abracon AB-RTCMC-32.768kHz-B5ZE-S3
RTC/Calendar module w/ I2C interface.
This support includes RTC time reading and setting, Alarm (1 minute
accuracy) reading and setting, and battery low detection. The device also
supports frequency adjustment and two timers but those features are
currently not implemented in this driver. Due to alarm accuracy
limitation (and current lack of timer support in the driver), UIE mode is
not supported.

Pull i2c updates from Wolfram Sang:
"For 3.19, the I2C subsystem has to offer special candy this time.
Right in time for Christmas :)
- I2C slave framework: finally, a generic mechanism for Linux being
an I2C slave (if the bus driver supports that). Docs are still
missing but will come later this cycle, the code is good enough to
go.
- I2C muxes represent their topology in sysfs much more detailed.
This will help users to navigate around much easier.
- irq population of i2c clients is now done at probe time, not device
creation time, to have better support for deferred probing.
- new drivers for Imagination SCB, Amlogic Meson
- DMA support added for Freescale IMX, Renesas SHMobile
- slightly bigger driver updates to OMAP, i801, AT91, and rk3x
(mostly quirk handling, timing updates, and using better kernel
interfaces)
- eeprom driver can now write with byte-access (very slow, but OK to
have)
- and the bunch of smaller fixes, cleanups, ID updates..."
