"This removes the currently unused CLASS_DDC support (controllers set
the flag, but there is no client to use it).
Also, CLASS_SPD support gets simplified to prepare removal in the
future. Class based instantiation is not recommended these days
anyhow.
Furthermore, I2C core now creates a debugfs directory per I2C adapter.
Current bus driver users were converted to use it.
Finally, quite some driver updates. Standing out are patches for the
wmt-driver which is refactored to support more variants.
This is the rebased pull request where a large series for the
designware driver was dropped"

Pull ARM SoC devicetree updates from Arnd Bergmann:
"The biggest change this time is for the 32-bit devicetree files, which
are all moved to a new location, using separate subdirectories for
each SoC vendor, following the same scheme that is used on arm64, mips
and riscv. This has been discussed for many years, but so far we never
did this as there was a plan to move the files out of the kernel
entirely, which has never happened.
The impact of this will be that all external patches no longer apply,
and anything depending on the location of the dtb files in the build
directory will have to change. The installed files after 'make
dtbs_install' keep the current location.
There are six added SoCs here that are largely variants of previously
added chips. Two other chips are added in a separate branch along with
their device drivers.
- The Samsung Exynos 4212 makes its return after the Samsung Galaxy
Express phone is addded at last. The SoC support was originally
added in 2012 but removed again in 2017 as it was unused at the
time.
- Amlogic C3 is a Cortex-A35 based smart IP camera chip
- Qualcomm MSM8939 (Snapdragon 615) is a more featureful variant of
the still common MSM8916 (Snapdragon 410) phone chip that has been
supported for a long time.
- Qualcomm SC8180x (Snapdragon 8cx) is one of their earlier high-end
laptop chips, used in the Lenovo Flex 5G, which is added along with
the reference board.
- Qualcomm SDX75 is the latest generation modem chip that is used as
a peripherial in phones but can also run a standalone Linux. Unlike
the prior 32-bit SDX65 and SDX55, this now has a 64-bit Cortex-A55.
- Alibaba T-Head TH1520 is a quad-core RISC-V chip based on the
Xuantie C910 core, a step up from all previously added rv64 chips.
All of the above come with reference board implementations, those
included there are 39 new board files, but only five more 32-bit this
time, probably a new low:
- Marantec Maveo board based on dhcor imx6ull module
- Endian 4i Edge 200, based on the armv5 Marvell Kirkwood chip
- Epson Moverio BT-200 AR glasses based on TI OMAP4
- PHYTEC STM32MP1-3 Dev board based on STM32MP15 PHYTEC SOM
- ICnova ADB4006 board based on Allwinner A20
On the 64-bit side, there are also fewer addded machines than we had
in the recent releases:
- Three boards based on NXP i.MX8: Emtop SoM & Baseboard, NXP i.MX8MM
EVKB board and i.MX8MP based Gateworks Venice gw7905-2x device.
- NVIDIA IGX Orin and Jetson Orin Nano boards, both based on tegra234
- Qualcomm gains support for 6 reference boards on various members of
their IPQ networking SoC series, as well as the Sony Xperia M4 Aqua
phone, the Acer Aspire 1 laptop, and the Fxtec Pro1X board on top
of the various reference platforms for their new chips.
- Rockchips support for several newer boards: Indiedroid Nova
(rk3588), Edgeble Neural Compute Module 6B (rk3588), FriendlyARM
NanoPi R2C Plus (rk3328), Anbernic RG353PS (rk3566), Lunzn
Fastrhino R66S/R68S (rk3568)
- TI K3/AM625 based PHYTEC phyBOARD-Lyra-AM625 board and Toradex
Verdin family with AM62 COM, carrier and dev boards
Other changes to existing boards contain the usual minor improvements
along with
- continued updates to clean up dts files based on dtc warnings and
binding checks, in particular cache properties and node names
- support for devicetree overlays on at91, bcm283x
- significant additions to existing SoC support on mediatek,
qualcomm, ti k3 family, starfive jh71xx, NXP i.MX6 and i.MX8, ST
STM32MP1

The Cadence I2C controller has an external reset that needs to be
de-asserted before the I2C controller can be accessed.
Document the `resets` devicetree property that can be used to describe how
the reset signal is connected.
While the reset signal will always be present in hardware the devicetree
property is kept optional for backwards compatibility with existing systems
that do not specify the reset property and where the reset signal might not
be controlled by operating system.

The depth of the FIFO of the Cadence I2C controller IP is a synthesis
configuration parameter. Different instances of the IP can have different
values. For correct operation software needs to be aware of the size of the
FIFO.
Add the documentation for the devicetree property that describes the FIFO
depth of the IP core.
The default value of 16 is for backwards compatibility reasons with
existing hardware descriptions where this property is not specified and

Pull devicetree updates from Rob Herring:
"DT core:
- Add node lifecycle unit tests
- Add of_property_present() helper aligned with fwnode API
- Print more information on reserved regions on boot
- Update dtc to upstream v1.6.1-66-gabbd523bae6e
- Use strscpy() to instead of strncpy() in DT core
- Add option for schema validation on %.dtb targets
Bindings:
- Add/fix support for listing multiple patterns in DT_SCHEMA_FILES
- Rework external memory controller/bus bindings to properly support
controller specific child node properties
- Convert loongson,ls1x-intc, fcs,fusb302, sil,sii8620, Rockchip
RK3399 PCIe, Synquacer I2C, and Synquacer EXIU bindings to DT
schema format
- Add RiscV SBI PMU event mapping binding
- Add missing contraints on Arm SCMI child node allowed properties
- Add a bunch of missing Socionext UniPhier glue block bindings and
example fixes
- Various fixes for duplicate or conflicting type definitions on DT
properties"

There are slave devices that understand I2C but have read-only SDA and
SCL. Examples are FD650 7-segment LED controller and its derivatives.
Typical board designs don't even have a pull-up for both pins.
Therefore add properties for not using open-drain. For write-only SCL
we have a property already, add one for write-only SDA.

The preferred form for Renesas' compatible strings is:
"<vendor>,<family>-<module>"
Somehow the compatible string for the r9a09g011 I2C IP was upstreamed
as renesas,i2c-r9a09g011 instead of renesas,r9a09g011-i2c, which
is really confusing, especially considering the generic fallback
is renesas,rzv2m-i2c.
The first user of renesas,i2c-r9a09g011 in the kernel is not yet in
a kernel release, it will be in v6.1, therefore it can still be
fixed in v6.1.
Even if we don't fix it before v6.2, I don't think there is any
harm in making such a change.
s/renesas,i2c-r9a09g011/renesas,r9a09g011-i2c/g for consistency.
