family. I2C on R-Car V3U also supports some extra features (e.g. Slave
Clock Stretch Select), which are supported by other R-Car Gen4 SoCs, but
not by any other R-Car Gen3 SoC.
Hence move its compatible value to the R-Car Gen4 section.

can support multiple serial interfaces like SPI,UART and I2C.
Unlike other I2C controllers, QUP I2C bindings are present in parent
schema. Move it out from parent to an individual binding and let parent
refer to child schema later on.
Please note, current schema isn't complete as it misses out few
properties and thus, add these missing properties along the process.

Used to define a local endpoint to communicate with MCTP peripherals
attached to an I2C bus. This I2C endpoint can communicate with remote
MCTP devices on the I2C bus.
In the example I2C topology below (matching the second yaml example) we
have MCTP devices on busses i2c1 and i2c6. MCTP-supporting busses are
indicated by the 'mctp-controller' DT property on an I2C bus node.
A mctp-i2c-controller I2C client DT node is placed at the top of the
mux topology, since only the root I2C adapter will support I2C slave
functionality.

"As usual, this is the bulk of the updates for the SoC tree, adding
more devices to existing files, addressing issues from ever improving
automated checking, and fixing minor issues.
The most interesting bits as usual are the new platforms. All the
newly supported SoCs belong into existing families this time:
- Qualcomm gets support for two newly announced platforms, both of
which can now work in production environments: the SDX65 5G modem
that can run a minimal Linux on its Cortex-A7 core, and the
Snapdragon 8 Gen 1, their latest high-end phone SoC.
- Renesas adds support for R-Car S4-8, the most recent automotive
Server/Communication SoC.
- TI adds support for J721s2, a new automotive SoC in the K3 family.
- Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
generation following their popular MT76xx series. Only basic
support is added for now.
- NXP i.MX8 ULP8 is a new low-power variant of the widespread i.MX8
series.
- TI SPEAr320s is a minor variant of the old SPEAr320 SoC that we
have supported for a long time.
New boards with the existing SoCs include
- Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
- AT91/SAMA5 based evaluation board
- NXP gains twenty new development and industrial boards for their
i.MX and Layerscape SoCs
- Intel IXP4xx now supports the final two machines in device tree
that were previously only supported in old style board files.
- Mediatek MT6589 is used in the Fairphone FP1 phone from 2013, while
MT8183 is used in the Acer Chromebook 314.
- Qualcomm gains support for the reference machines using the two new
SoCs, plus a number of Chromebook variants and phones based on the
Snapdragon 7c, 845 and 888 SoCs, including various Sony Xperia
devices and the Microsoft Surface Duo 2.
- ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
- Tegra now boots various older Android devices based on 32-bit chips
out of the box, including a number of ASUS Transformer tablets.
There is also a new Jetson AGX Orin developer kit.
- Apple support adds the missing device trees for all the remaining
M1 Macbook and iMac variants, though not yet the M1 Pro/Max
versions.
- Allwinner now supports another version of the Tanix TX6 set-top box
based on the H6 SoC.
- Broadcom gains support for the Netgear RAXE500 Wireless router
