For certain revisions of the I2C controller (e.g., iProc NIC I2C), I2C

"The biggest highlight here is the start of using json-schema for DT

- Initial support for DT bindings using json-schema language. This is
the start of converting DT bindings from free-form text to a
structured format.
- Reworking of initrd address initialization. This moves to using the
phys address instead of virt addr in the DT parsing code. This
rework was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary
rebuilding of lots of files.
- Fix stale phandle entries in phandle cache
- DT overlay validation improvements. This exposed several memory
leak bugs which have been fixed.
- Use node name and device_type helper functions in DT code
- Last remaining conversions to using %pOFn printk specifier instead
of device_node.name directly
- Create new common RTC binding doc and move all trivial RTC devices

'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.

"AT24 updates for 4.16 merge window
The driver has been converted to using regmap instead of raw i2c and
smbus calls which shrank the code significantly.
Device tree binding document has been cleaned up. Device tree support in
the driver has been improved and we now support all at24 models as well
as two new DT properties (no-read-rollover and wp-gpios).
We no longer user unreadable magic values for driver data as the way it
was implemented caused problems for some EEPROM models - we switched to
regular structs.
Aside from that, there's a bunch of coding style fixes and minor
improvements all over the place."

In order to use i2c from a cold boot, the i2c peripheral must be taken
out of reset. We request a shared reset controller each time a bus
driver is loaded, as the reset is shared between the 14 i2c buses.
On remove the reset is asserted, which only touches the hardware once
the last i2c bus is removed.
The reset is required as the I2C buses will not work without releasing
the reset. Previously the driver only worked with out of tree hacks
that released this reset before the driver was loaded. Update the
device tree bindings to reflect this.

The current i2c-gpio DT bindings use a single unnamed "gpios" property
to refer to the SDA and SCL signal lines by index. This is error-prone
for the casual DT writer and reviewer, as one has to look up the order
in the DT bindings.
Fix this by amending the DT bindings to use two separate named gpios
properties, and deprecate the old unnamed variant.
Take this opportunity to clearly deprecate the "i2c-gpio,sda-open-drain"
and "i2c-gpio,scl-open-drain" flags as well. The commit describes
in detail what these flags actually mean, and why they should not be
used in new device trees.

Device-tree updates for arm64 platforms. For the first time I can
remember, this is actually larger than the corresponding branch for
32-bit platforms overall, though that has more individual changes.
A significant portion this time is due to added machine support:
- Initial support for the Realtek RTD1295 SoC, along with the Zidoo
X9S set-top-box
- Initial support for Actions Semi S900 and the Bubblegum-96
single-board-cёmputer.
- Rockchips support for the rk3399-Firefly single-board-computer
gets added, this one stands out for being relatively fast,
affordable and well₋supported, compared to many boards that
only fall into one or two of the above categories.
- Mediatek gains support for the mt6797 mobile-phone SoC platform
and corresponding evaluation board.
- Amlogic board support gets added for the NanoPi K2 and S905x
LibreTech CC single-board computers and the R-Box Pro set-top-box
- Allwinner board support gets added for the OrangePi Win,
Orangepi Zero Plus 2, NanoPi NEO2 and Orange Pi Prime single
board computers and the SoPine system-on-module.
- Renesas board support for Salvator-XS and H3ULCB
automotive development systems.
- Socionext Uniphier board support for LD11-global and LD20-global,
whatever those may be.
- Broadcom adds support for the new Stingray communication processor
in its iProc family, along with two reference boards.
Other updates include:
- For the hisicon platform, support for Hi3660-Hikey960 gets
extended significantly.
- Lots of smaller updates for Renesas, Amlogic, Rockchip, UniPhier,
Broadcom, Allwinner, Hisilicon, Qualcomm, Marvell, and NXP.

In Tegra186, the BPMP (Boot and Power Management Processor) owns certain
HW devices, such as the I2C controller for the power management I2C bus.
Software running on other CPUs must perform IPC to the BPMP in order to
execute transactions on that I2C bus. This binding describes an I2C bus
that is accessed in such a fashion.

breaks some drivers which alter their functionality depending on whether

I2C_CLIENT_HOST_NOTIFY.
For DT-based systems we introduce "host-notify" property that we convert
to I2C_CLIENT_HOST_NOTIFY board flag.

A couple of interesting new SoC platforms are now supported, these are
the respective DTS sources:
- Samsung Exynos5433 mobile phone platform, including an (almost) fully
supported phone reference board.
- Hisilicon Hip07 server platform and D05 board, the latest iteration
of their product line, now with 64 Cortex-A72 cores across two
sockets.
- Allwinner A64 SoC, the first 64-bit chip from their "sunxi" product
line, used in Android tablets and ultra-cheap development boards
- NXP LS1046A Communication processor, improving on the earlier LS1043A
with faster CPU cores
- Qualcomm MSM8992 (Snapdragon 808) and MSM8994 (Snapdragon 810)
mobile phone SoCs
- Early support for the Nvidia Tegra Tegra186 SoC
- Amlogic S905D is a minor variant of their existing Android consumer
product line
- Rockchip PX5 automotive platform, a close relative of their popular
rk3368 Android tablet chips
Aside from the respective evaluation platforms for the above
chips, there are only a few consumer devices and boards added
this time:
- Huawei Nexus 6P (Angler) mobile phone
- LG Nexus 5x (Bullhead) mobile phone
- Nexbox A1 and A95X Android TV boxes
- Pine64 development board based on Allwinner A64
- Globalscale Marvell ESPRESSOBin community board based on Armada 3700

For the existing platforms, we get bug fixes and new peripheral support
for Juno, Renesas, Uniphier, Amlogic, Samsung, Broadcom, Rockchip, Berlin,
and ZTE.
Conflicts:
- Documentation/devicetree/bindings/arm/shmobile.txt: a
rename/add conflict, keep both modifications and maintain
alphabetical ordering.
- arch/arm64/boot/dts/*/*.dtsi: nodes were added in netdev,

- the first series of making i2c_device_id optional instead of
mandatory (in favor of alternatives like of_device_id).
This involves adding a new probe callback (probe_new) which removes
some peculiarities I2C had for a long time now. The new probe is
matching the other subsystems now and the old one will be removed
once all users are converted. It is expected to take a while but
there is ongoing interest in that.

Add per-Generation fallback bindings for R-Car SoCs.
This is in keeping with the compatibility string scheme is being adopted
for drivers for Renesas SoCs.
Also, improve readability by listing the rmobile fallback compatibility
string after the more-specific compatibility strings they provide a
fallback for.

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and Gen 3. But beyond that it's not clear what the
relationship between IP blocks might be. For example, I believe that
r8a7790 is older than r8a7791 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 is being adopted for
drivers for Renesas SoCs.
Also:
* Deprecate renesas,i2c-rcar. It seems poorly named as it is only
compatible with R-Car Gen 1. It also appears unused in mainline.
* Add some text to describe per-SoC bindings

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.

- 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.
"nxp,pcf2127" and "nxp,pcf2129" are I2c devices, adds them to the list
of trivial i2c devices.

Similar to the new optional 'i2c-bus' subnode from Jon Hunter, this
adds an optional 'i2c-mux' subnode, for similar reasons. I.e. it is
bad of the i2c mux core to assume that any subnode of an i2c mux device
is a potential (when the 'reg' property matches) i2c-mux child bus,
given that i2c mux devices might do more than mux i2c traffic.
So, if an 'i2c-mux' subnode is present, dictate that all i2c-mux child
buses exist beneath that subnode.

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.

The I2C driver core for boards using device-tree assumes any subnode of
an I2C adapter in the device-tree blob is an I2C slave device. Although
this makes complete sense, some I2C adapters may have subnodes which
are not I2C slaves but subnodes presenting other features. For example
some Tegra devices have an I2C interface which may share its pins with
other devices. In order to share these pins using the pinctrl framework,
it is necessary to add subnodes to the I2C device node that represent
these pins.
To allow I2C adapters to have non-I2C specific subnodes in device-tree
that are not parsed by the I2C driver core, add support for an optional
'i2c-bus' subnode where I2C slaves can be placed. If the 'i2c-bus'
subnode is present then all I2C slaves must be placed under this
subnode.
