The ST M24256E behaves as a regular M24C256, except for the E variant
which uses up another I2C address for Additional Write lockable page.
This page is 64 Bytes long and can contain additional data. Add entry
for it, so users can describe that page in DT. Note that users still
have to describe the main M24C256 area separately as that is on separate
I2C address from this page.
Unlike M24C32-D and M24C64-D, this part is specifically ST and does not
have any comparable M24* counterparts from other vendors, hence the st,
vendor prefix. Furthermore, the part name is M24256E without C between
the 24 and 256, this is not a typo. Finally, there is M24C256-D part,
which does contain 32 Bytes long Additional Write lockable page, which
is a different part and not supported by this patch.

git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-mergewindow
The DesignWare and the Renesas I2C drivers have received most of
the changes in this pull request.
The first has has undergone through a series of cleanups that
have been sent to the mailing list a year ago for the first time
and finally get merged in this pull request. They are many, from
typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
inline functions to librarieas) and many others.
Besides that, all the DesignWare Kconfig options have been
grouped under the I2C_DESIGNWARE_CORE and this required some
adaptation in many of the kernel configuration files for
different arm and mips boards.
Follows the list of the rest of the changes grouped by type of
change.
Cleanups
--------
The Qualcomm Geni platform improves the exit path in the runtime
resume function.
The Intel LJCA driver loses "target_addr" parameter in
ljca_i2c_stop() because it was unused.
The MediaTek controller intializes the restart_flag in the
transfer function using the ternary conditional operator ("? :")
instead of initializing it in different parts.
Constified a few global data structures in the virtio driver.
The Renesas driver simplifies the bus speed handling in the init
function making it more readable.
Improved an if/else statement in probe function of the Renesas
R-Car driver.
The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
of SET_RUNTIME_PM_OPS().
Still in the iMX/MXC driver a comma ',' has been replaced by a
semicolon ';', while in different drivers the ',' has been
removed from the '{ }' delimiters.
Finally three devm_clk_get_enabled() have been used to simplify
the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
Ingenic and MPC drivers.
Refactors
---------
The Nuvoton fixes a potential out of boundary array access. This
is not a bug fix because the issue could never occur due to
hardware not having the properties listed in the array. The
change makes the driver more future proof and, at the same time,
silences code analyzers.
Improvements
------------
The Renesas I2C (riic) driver undergoes several patches improving
the runtime power management handling.
The Intel i801 driver uses a more descriptive adapter's name to
show the presence of the IDF feature.
In the Intel Denverton (ismt) adapter the pending transactions
are killed when irq's can't complete their handling, triggering a
timeout. This could have been considered as a bug fix, but
because, standing to Vasily, it's very sporadic, I preferred
considering the patch rather as an improvement.
New Feature
-----------
The Renesas I2C (riic) driver now supports the fast mode plus.
New support
-----------
Added support for:
- Renesas R9A08G045
- Rockchip RK3576
- KEBA I2C
- Theobroma Systems Mule Multiplexer.
The Keba comes with a new driver, i2c-keba.c.
The Mule is an i2c multiplexer and it also comes with a new
driver, mux/i2c-mux-mule.c.
Core patch
----------
This pull request includes also a patch in the I2C framework, in
i2c-core-base.c where the runtime PM functions have been replaced
in order to allow to be accessed during the device add.
Devicetree
----------
Some cleanups in the devicetree, as well. nVidia and Qualcomm
bindings improve their "if:then:" blocks. While the aspeed
binding loses the "multi-master" property because it was
redundant.
The i2c-sprd binding has been converted to YAML.

The schema for the ST M24C64-D compatible string doesn't work.
Validation fails as the 'd-wl' suffix is not added to the preceeding
schema which defines the entries and vendors. The actual users are
incorrect as well because the vendor is listed as Atmel whereas the
part is made by ST.
As this part doesn't appear to have multiple vendors, move it to its own
entry.

SPI and I2C bus node names are expected to be "spi" or "i2c",
respectively, with nothing else, a unit-address, or a '-N' index. A
pattern of 'spi0' or 'i2c0' or similar has crept in. Fix all these
cases. Mostly scripted with the following commands:
git grep -l '\si2c[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/i2c[0-9] {/i2c {/'
git grep -l '\sspi[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/spi[0-9] {/spi {/'

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.

DT properties which can have multiple entries need to specify what the
entries are and define how many entries there can be. In the case of
only a single entry, just 'maxItems: 1' is sufficient.
Add the missing entry constraints. These were found with a modified
meta-schema. Unfortunately, there are a few cases where the size
constraints are not defined such as common bindings, so the meta-schema
can't be part of the normal checks.

The correct syntax for JSON pointers begins with a '/' after the '#'.
Without a '/', the string should be interpreted as a subschema
identifier. The jsonschema module currently doesn't handle subschema
identifiers and incorrectly allows JSON pointers to begin without a '/'.
Let's fix this before it becomes a problem when jsonschema module is
fixed.

emulate SMBus HostNotify support (STM32 and R-Car added this so far)
- 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
- rest is driver updates

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.

Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.
Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.
So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.

Currently the at24 driver only creates additional i2c dummies for
atmel,24c00 and it's hard-coded. Some other chips (like for example
Microchip's 24AA02T) also take more slave addresses despite being
otherwise compatible with already supported variants.
Add a new property to the device tree binding document that defines
the total number of i2c slave addresses taken by the device. The
addresses are counted starting from the one in the reg property.
