112dfa5ca1 dt-bindings: i2c: renesas,riic: Add interrupt-names
The Renesas RZ/A and RZ/G2L I2C Bus Interface has no less than 8
interrupts.  Hence document the "interrupt-names" property, to make it
easier to review the interrupt mappings in DTS files.

Note that this property cannot be made required yet, as the RIIC nodes
in all DTS files lack the property.

e083bbd604 ARM: Devicetree material for 5.14
Like always, the DT branch is sizable. There are numerous additions and
 fixes to existing platforms, but also a handful of new ones introduced.
 Less than some other releases, but there's been significant work on
 cleanups, refactorings and device enabling on existing platforms.
 
 A non-exhaustive list of new material:
 
  - Refactoring of BCM2711 dtsi structure to add support for the Raspberry Pi 400
  - Rockchip: RK3568 SoC and EVB, video codecs for rk3036/3066/3188/322x
  - Qualcomm: SA8155p Automotive platform (SM8150 derivative),
    SM8150/8250 enhancements and support for Sony Xperia 1/1II and 5/5II
  - TI K3: PCI/USB3 support on AM64-sk boards, R5 remoteproc definitions
  - TI OMAP: Various cleanups
  - Tegra: Audio support for Jetson Xavier NX, SMMU support on Tegra194
  - Qualcomm: lots of additions for peripherals across several SoCs, and
    new support for Microsoft Surface Duo (SM8150-based), Huawei Ascend G7.
  - i.MX: Numerous additions of features across SoCs and boards.
  - Allwinner: More device bindings for V3s, Forlinx OKA40i-C and NanoPi
    R1S H5 boards
  - MediaTek: More device bindings for mt8167, new Chromebook system
    variants for mt8183
  - Renesas: RZ/G2L SoC and EVK added
  - Amlogic: BananaPi BPI-M5 board added

972d6a7dce dt-bindings: Drop redundant minItems/maxItems
If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

This condition is partially checked with the meta-schema already, but
only if both 'minItems' and 'maxItems' are equal to the 'items' length.
An improved meta-schema is pending.

According to the Hardware User's Manual, automatic transmission for PMIC
control (DVFS) is not available on the R-Car E3 and RZ/G2E SoC.
Experiments showed this really means that support for automatic DVFS is
not present, while the IIC automatic transmission feature itself is
still available, albeit not super useful.

Hence there is no longer a reason not to declare compatibility with the
R-Car Gen3-specific and generic versions, and the corresponding
paragraph can be dropped.

 - the testunit can now respond to SMBus block process calls which is

32ada6b098 dt-bindings: Cleanup standard unit properties
Properties with standard unit suffixes already have a type and don't need
type definitions. They also default to a single entry, so 'maxItems: 1'
can be dropped.

adi,ad5758 is an oddball which defined an enum of arrays. While a valid
schema, it is simpler as a whole to only define scalar constraints.

4aa5b78fb5 dt-bindings: i2c: dw: cancel mandatory requirements for "#address-cells" and "#size-cells"
The "#address-cells" and "#size-cells" are required only when the I2C
controller has subnodes. However, some I2C controllers defined in
"arch/arm64/boot/dts/amd/" and "arch/arm64/boot/dts/hisilicon/"
directories do not have child nodes. So they don't need these two
properties and don't write them explicitly.

Therefore, setting properties "#address-cells" and "#size-cells" as
"required" in this yaml file causes the following warnings:
/root/linux-next/arch/arm64/boot/dts/hisilicon/hi6220-hikey.dt.yaml: \
i2c@f7100000: '#address-cells' is a required property

 - if a host can be a client, too, the I2C core can now use it to

 - also for client mode, a testunit has been added. It can create rare
   situations on the bus, so host controllers can be tested

 - a binding has been added to mark the bus as "single-master". This
   allows for better timeout detections

 - new driver for Mellanox Bluefield

 - massive refactoring of the Tegra driver

 - EEPROMs recognized by the at24 driver can now have custom names

6fdc6e23a7 dt-bindings: Add missing 'unevaluatedProperties'
This doesn't yet do anything in the tools, but make it explicit so we can
check either 'unevaluatedProperties' or 'additionalProperties' is present
in schemas.

'unevaluatedProperties' is appropriate when including another schema (via
'$ref') and all possible properties and/or child nodes are not
explicitly listed in the schema with the '$ref'.

This is in preparation to add a meta-schema to check for missing
'unevaluatedProperties' or 'additionalProperties'. This has been a
constant source of review issues.

add a "ingenic,jz4770-i2c" string and use it as fallback for the

f516fb704d dt-bindings: Whitespace clean-ups in schema files
Clean-up incorrect indentation, extra spaces, long lines, and missing
EOF newline in schema files. Most of the clean-ups are for list
indentation which should always be 2 spaces more than the preceding
keyword.

Found with yamllint (which I plan to integrate into the checks).

The I2C GPIO bus recovery properties consist of two GPIOS and one extra

Not all are mandatory for recovery.

a451c3be0f dt-bindings: i2c-gpio: Use 'deprecated' keyword on deprecated properties
The i2c-gpio binding is the only case of 'not: true' being used for a
deprecated property. Update it to use the json-schema 2019.09
'deprecated' keyword instead. Define the type too in order to keep the
meta-schema happy.

This will disable warnings for these properties until the dtschema tools
are updated to handle 'deprecated', but they are only used in a few at91
dts files.

A conversion of the i2c-pxa binding to DT schema format using json-schema.

This also cleans ups some errors in the binding: The compatible string
description suggested that "mmp" in "mrvl,mmp-twsi" is to be substituted
with a processor model, which wouldn't be a right thing to do and indeed
nobody seems to have been doing that. There also was "Recommended
properties" section that included optional as well as mandatory
properties. Missing mandatory properties were added to the example.

 "I2C has quite some patches for you this time. I hope it is the move to
  per-driver-maintainers which is now showing results. We will see.

  The big news is two new drivers (Nuvoton NPCM and Qualcomm CCI),
  larger refactoring of the Designware, Tegra, and PXA drivers, the
  Cadence driver supports being a slave now, and there is support to
  instanciate SPD eeproms for well-known cases (which will be
  user-visible because the i801 driver supports it), and some
  devm_platform_ioremap_resource() conversions which blow up the
  diffstat.

  Note that I applied the Nuvoton driver quite late, so some minor fixup
  patches arrived during the merge window. I chose to apply them right
  away because they were trivial"

i2c "reg" property. If dtc finds an i2c-slave sub-node having an address
higher than ten-bits wide it'll print an ugly warning:

Warning (i2c_bus_reg): /example-2/i2c@1120000/eeprom@64: I2C bus unit address format error, expected "40000064"
Warning (i2c_bus_reg): /example-2/i2c@1120000/eeprom@64:reg: I2C address must be less than 10-bits, got "0x40000064"

In order to silence dtc up let's replace the corresponding DT binding
example with a normal DW I2C master mode-based one. It's done by clearing
the I2C_OWN_SLAVE_ADDRESS bit in the reg property and converting the
sub-node to be compatible with normal EEPROM like "atmel,24c02".

Just revert this commit when dtc is fixed.

3264d9e5cf dt-bindings: i2c: Convert DW I2C binding to DT schema
Modern device tree bindings are supposed to be created as YAML-files
in accordance with dt-schema. This commit replaces Synopsys DW I2C
legacy bare text bindings with YAML file. As before the bindings file
states that the corresponding dts node is supposed to be compatible
either with generic DW I2C controller or with Microsemi Ocelot SoC I2C
one, to have registers, interrupts and clocks properties. In addition
the node may have clock-frequency, i2c-sda-hold-time-ns,
i2c-scl-falling-time-ns and i2c-sda-falling-time-ns optional properties.

3d21a46093 dt-bindings: Remove cases of 'allOf' containing a '$ref'
json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.

This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.

Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

1de20644c4 dt-bindings: i2c: brcmstb: Add BCM2711 BSC/AUTO-I2C binding
The HDMI blocks in the BCM2771 have an i2c controller to retrieve the
EDID. This block is split into two parts, the BSC and the AUTO_I2C,
lying in two separate register areas.

The AUTO_I2C block has a mailbox-like interface and will take away the
BSC control from the CPU if enabled. However, the BSC is the actually
the same controller than the one supported by the brcmstb driver, and
the AUTO_I2C doesn't really bring any immediate benefit.

We can model it in the DT as a single device with two register range,
which will allow us to use or or the other in the driver without
changing anything in the DT.

4abfe6f04d dt-bindings: i2c: Convert UniPhier FI2C controller to json-schema
Convert the UniPhier FIFO-builtin I2C (a.k.a. FIFO) controller binding
to DT schema format.

There are two types of I2C controllers used on the UniPhier platform.
This is the new one with FIFO support, which is used on the Pro4 SoC
or newer.

Pull i2c updates from Wolfram Sang:
 "i2c core:

   - huge improvements and refactorizations of the Linux I2C
     documentation (lots of thanks to Luca for doing it and Jean for the
     careful review)

   - subsystem wide API conversion to i2c_new_client_device()

   - remove obsolete parport-light driver

   - smaller core updates (removal of 'extern', enabling more compile
     testing, use more helper macros)

   - and quite a bunch of driver updates (new IDs, simplifications,
     better PM, support of atomic transfers and other improvements)

  i2c-mux:

   - The main feature is the idle-state rework of the pca954x driver
     from Biwen Li

  at24 driver:

   - minor maintenance: update the license tag, sort headers

   - move support for the write-protect pin into nvmem core

   - add a reference to the new wp-gpios property in nvmem to at25
     bindings

   - add support for regulator and pm_runtime control"

b644257f0e dt-bindings: i2c: add bindings for i2c analog and digital filter
Some i2c controllers have a built-in digital or analog filter.
This is specifically required depending on the hardware PCB/board.
Some controllers also allow specifying the maximum width of the
spikes that can be filtered for digital filter. The width length can be
specified in nanoseconds.
Analog filters can be configured to have a cutoff frequency (low-pass filter).
This frequency can be specified in Hz.
Added an optional property for such types of analog filters.

7c672abc12 It's a somewhat calmer cycle for docs this time, as the churn of the mass
RST conversion is happily mostly behind us.
 
  - A new document on reproducible builds.
 
  - We finally got around to zapping the documentation for hardware support
    that was removed in 2004; one doesn't want to rush these things.
 
  - The usual assortment of fixes, typo corrections, etc.
 
 You'll still find a handful of annoying conflicts against other trees,
 mostly tied to the last RST conversions; resolutions are straightforward
 and the linux-next ones are good.

0038617132 dt-bindings: i2c: sun6i-p2wi: Fix the binding example
Even though the binding claims that the frequency can go up to 6MHz, the
common i2c binding sets a limit at 3MHz, which then triggers a warning.

Since the only SoC that uses that bus uses a frequency of 100kHz, and that
this bus hasn't been found in an SoC for something like 5 years, let's just
fix the example to have a frequency within the acceptable range for i2c.

Pull Devicetree updates from Rob Herring:
 "The biggest highlight here is the start of using json-schema for DT
  bindings. Being able to validate bindings has been discussed for years
  with little progress.

   - 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
     out of trivial-devices.txt.

   - New bindings for Freescale MAG3110 magnetometer, Cadence Sierra
     PHY, and Xen shared memory

   - Update dtc to upstream version v1.4.7-57-gf267e674d145"

Pull i2c updates from Wolfram Sang:

 - the core has now a lockless variant of i2c_smbus_xfer. Some open

   proper SCCB support in regmap.

 - locking got a more precise naming. i2c_{un}lock_adapter() had to go,
   and we know use i2c_lock_bus() consistently with flags like
   I2C_LOCK_ROOT_ADAPTER and I2C_LOCK_SEGMENT to avoid ambiguity.

 - the gpio fault injector got a new delicate testcase

 - the bus recovery procedure got fixed to handle the new testcase
   correctly

 - a new quirk flag for controllers not able to handle zero length
   messages together with driver updates to use it

 - new drivers: FSI bus attached I2C masters, GENI I2C controller, Owl
   family S900

 - and a good set of driver improvements and bugfixes

791d3ef2e1 dt-bindings: remove 'interrupt-parent' from bindings
'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."

edd20e95bc i2c: aspeed: Deassert reset in probe
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.

7d29f509d2 dt-bindings: i2c: i2c-gpio: Add support for named gpios
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.

Pretty much any node can have a status property, so it doesn't need to

a9ceea2674 ARM: 64-bit DT updates
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.

6a405f7c5d dt-bindings: Add Tegra186 BPMP I2C binding
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.

331c342552 i2c: do not enable fall back to Host Notify by default
Falling back unconditionally to HostNotify as primary client's interrupt
breaks some drivers which alter their functionality depending on whether
interrupt is present or not, so let's introduce a board flag telling I2C
core explicitly if we want wired interrupt or HostNotify-based one:
I2C_CLIENT_HOST_NOTIFY.

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

de399813b5 powerpc updates for 4.10
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.

 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
 - Renesas "R-Car Starter Kit Pro" (M3ULCB) low-cost automotive  board
 
 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,

8600b697cd Merge branch 'i2c/for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:

 - 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.

 - SMBus Host Notify introduced 4.9 got refactored. They are now using
   interrupts instead of the alert callback which solves multiple
   issues.

 - new drivers for iMX LowPower I2C, Mellanox CPLD and its I2C mux

 - significant refactoring for bcm2835 driver

 - the usual set of driver updates and improvements

b880ccaf17 i2c: sh_mobile: Add per-Generation fallback bindings
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.

ad4a8dc3fe i2c: rcar: Add per-Generation fallback bindings
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

c7c88e998a 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.

  - 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

* 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.

  - 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.

374f8436ff dt-bindings: i2c: add support for 'i2c-mux' subnode
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.

Greg Kroah-Hartman
d5bd1eba19 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

Merge tag 'iio-for-4.9a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into work-testing

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.

f64d6e2aaa DeviceTree update for 4.8:
- Removal of most of_platform_populate() calls in arch code. Now the DT
 core code calls it in the default case and platforms only need to call
 it if they have special needs.
 
 - Use pr_fmt on all the DT core print statements.
 
 - CoreSight binding doc improvements to block name descriptions.
 
 - Add dt_to_config script which can parse dts files and list
 corresponding kernel config options.
 
 - Fix memory leak hit with a PowerMac DT.
 
 - Correct a bunch of STMicro compatible strings to use the correct
 vendor prefix.
 
 - Fix DA9052 PMIC binding doc to match what is actually used in dts
 files.

0e13f99d3a Documentation: dt: i2c: use correct STMicroelectronics vendor prefix
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 command flow is exactly the same, the core simply needs to be
told to enable TPM2 mode when the compatible string indicates a
TPM2.
