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

Pull i2c updates from Wolfram Sang:
- if a host can be a client, too, the I2C core can now use it to
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

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.

The I2C controller in the JZ4770 SoC seems to work the exact same as in
the JZ4780 SoC.
We could use "ingenic,jz4780-i2c" as a fallback string in the Device
Tree, but that would be awkward, since the JZ4780 is newer. Instead,
add a "ingenic,jz4770-i2c" string and use it as fallback for the
"ingenic,jz4780-i2c" string.

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

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

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

- A bunch more binding conversions to DT schema. Only 3K to go.
- Add a minimum version check for schema tools
- Treewide dropping of 'allOf' usage with schema references. Not needed
in new json-schema spec.
- Some formatting clean-ups of schemas

It is useful to know if we are the only master on a given bus. Because
this is a HW description of the bus, add it to the generic bindings.

Add the "baikal,bt1-sys-i2c" compatible string to the DW I2C binding. Even
though the corresponding node is supposed to be a child of the Baikal-T1
System Controller, its reg property is left required for compatibility.

dtc currently doesn't support I2C_OWN_SLAVE_ADDRESS flag set in the
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.

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.
