My name is stamped into maintainership for a big slew of DT
bindings. Now that it is changing, switch it over to my
kernel.org mail address, which will hopefully be stable for the
rest of my life.

Move several embedded controller bindings (like ChromeOS EC, Gateworks
System Controller and Kontron sl28cpld Board Management) to new
subdirectory "embedded-controller" matching their purpose.
An embedded controller (EC) is a discrete component that contains a
microcontroller (i.e. a small CPU running a small firmware without
operating system) mounted into a larger computer system running
a fully fledged operating system that needs to utilize the embedded
controller as part of its operation.
So far the EC bindings were split between "mfd" and "platform"
directory. MFD name comes from Linux, not hardware, and "platform" is a
bit too generic.
Rename Gateworks GSC and Huawei Gaokun filenames to match compatible, as
preferred for bindings.

After discussion with the devicetree maintainers we agreed to not extend
lists with the generic compatible "apple,wdt" anymore [1]. Use
"apple,t8103-wdt" as base compatible as it is the SoC the driver and
bindings were written for.
The block on the Apple M2 Pro/Max/Ultra SoCs is compatible with the
existing driver so add its per-SoC compatible.

Extend the Renesas WDT device tree bindings to support the watchdog timer
found on the RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs.
The RZ/T2H WDT is mostly compatible with the one found on the RZ/V2H(P),
but includes an additional register and differs in the clock division
ratio settings for the WDTCR[CKS] field. To reflect these differences,
introduce a new compatible string, "renesas,r9a09g077-wdt".
The binding schema is updated accordingly. On RZ/T2H, the WDT does not
require the "resets" property. It also requires two register regions and
the presence of a "power-domains" property. The "clock-names" property is
limited to a single entry, "pclk", for this SoC.
The RZ/N2H SoC uses the same WDT IP as the RZ/T2H. It is supported by
using "renesas,r9a09g087-wdt" as the primary compatible string, with
"renesas,r9a09g077-wdt" listed as a fallback to describe the shared
hardware features.
Example:
wdt0: watchdog@80082000 {
compatible = "renesas,r9a09g077-wdt";
reg = <0 0x80082000 0 0x400>,
<0 0x81295100 0 0x04>;
clocks = <&cpg CPG_CORE R9A09G077_CLK_PCLKL>;
clock-names = "pclk";
power-domains = <&cpg>;
status = "disabled";
};

Pull SoC devicetree updates from Arnd Bergmann:
"There are a few new variants of existing chips:
- mt6572 is an older mobile phone chip from mediatek that was
extremely popular a decade ago but never got upstreamed until now
- exynos2200 is a recent high-end mobile phone chip used in a few
Samsung phones like the Galaxy S22
- Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M
(R8A779H0) and used in automotive applications
- Tegra264 is a new chip from NVIDIA, but support is fairly minimal
for now, and not much information is public about it
There are five more chips in a separate branch, as those are new chip
families that I merged along with the necessary infrastructure.
New board support is not that exciting, with a total of 33 newly added
machines here:
- Evaluation platforms for the chips above, plus TI am62d2 and Sophgo
sg2042
- Six 32-bit industrial boards based on stm32, imx6 and am33 chips,
plus eight 64-bit rockchips rk33xx/rk35xx, am62d2, t527, imx8 and
imx95
- Two newly added ASPEED BMC based motherboards, and one that got
removed
- Phones and Tablets based on 32-bit mt6572, tegra30 and 64-bit
msm8976 SoCs
- Three Laptops based on Mediatek mt8186 and Qualcomm Snapdragon X1
- A set-top box based on Amlogic meson-gxm
Updates for existing machines are spread over all the above families.
One notable change here is support for the RP1 I/O chip used in
Raspberry Pi 5"

(R9A09G056) SoC. The watchdog IP is identical to that on RZ/V2H(P),
so `renesas,r9a09g057-wdt` will be used as a fallback compatible,

Add a dt-binding compatible for the Exynos990 Watchdog timer.
This watchdog is compatible with the GS101/Exynos850 design, as
such it requires the cluster-index and syscon-phandle properties
to be present. It also contains a cl2 cluster, as such the
cluster-index property has been expanded.

previous SoCs, but moves some registers around (by just one word), making
it incompatible to existing IPs.

of IP requiring two clock inputs.

Pull SoC devicetree updates from Arnd Bergmann:
"This release adds the devicetree files for an impressive number of new
SoC variants, though as expected these are all related to others we
already support:
- The microchip sam9x7 devicetree is now added, after the device
driver and platform code has already made it in. This is likely the
last ARMv5 (!) platform to ever get added, updating the 20+ year
old at91/sam9 platform with DDR3 memory and gigabit ethernet.
- On the Apple platform, there are now devicetree files for a number
of A-series SoCs in addition to the M-series ones, these are used
primarily in phones and tablets, but are closely related to the
already supported chips.
- Samsung Exynos 8895 and Exynos 990 are more phone SoCs used in
older Samsung Galaxy phones.
- Qualcomm Snapdragon 778G (SM7325) is another phone SoC, closely
related to the Snapdragon 7c+ Gen 3 (SC7280) used in low-end
laptops.
- Rockchip RK3528 and RK3576 are new variants of their TV box and
Tablet chips, still using the older ARMv8.0 cores from
RK3328/RK3399 but with a newer process and other improvements from
the RK35xx (otherwise ARMv8.2) chips. RK3566T and RK3399-S are also
added, these are just lower-cost versions of their normal
counterparts.
- TI J742S2 is a feature-reduced version of the J784s4
industrial/automotive SoC, with fewer CPU cores.
- Sophgo SG2002 is an embedded SoC with one RISC-V (C906) and one ARM
(Cortex-A53) core, at this point support is only added for running
on the RISC-V side on the LicheeRV Nano board.
A total of 92 new .dts files describing individual machines is added,
which must be a new record. The majority of these is for the newly
added chips above, notably all the Apple phones and tablets. The other
new machines include nine industrial/embedded boards with NXP i.MX6 or
i.MX8 SoCs, eight for Rockchips RK35XX and one or two each for
Rockchips RV1109, RK3308, Allwinner A33, Tegra 234, Qualcomm
qcs9100/sc8280xp/x1e80100, TI AM625 and Starfive JH7110.
As usual there are also many newly added features in existing boards
as well as cleanups and minor bugfixes"
