Pull more clocksource updates from Thomas Gleixner:
 "A set of updates for clocksource and clockevent drivers:

   - A fix for the prescaler of the ARM global timer where the prescaler
     mask define only covered 4 bits while it is actully 8 bits wide.
     This obviously restricted the possible range of prescaler
     adjustments

   - A fix for the RISC-V timer which prevents a timer interrupt being
     raised while the timer is initialized

   - A set of device tree updates to support new system on chips in
     various drivers

   - Kernel-doc and other cleanups all over the place"

c819dbd078 dt-bindings: timer: Add support for cadence TTC PWM
Cadence TTC can act as PWM device, it will be supported through
separate PWM framework based driver. Decision to configure
specific TTC device as PWM or clocksource/clockevent would
be done based on presence of "#pwm-cells" property.

Also, interrupt property is not required for TTC PWM driver.
Update bindings to support TTC PWM configuration.

Some Timer Unit (TMU) instances with 3 channels support a fourth

b91cf01cf3 dt-bindings: timer: thead,c900-aclint-mtimer: separate mtime and mtimecmp regs
The timer registers of aclint don't follow the clint layout and can
be mapped on any different offset. As sg2042 uses separated timer
and mswi for its clint, it should follow the aclint spec and have
separated registers.

The previous patch introduced a new type of T-HEAD aclint timer which
has clint timer layout. Although it has the clint timer layout, it
should follow the aclint spec and uses the separated mtime and mtimecmp
regs. So a ABI change is needed to make the timer fit the aclint spec.

To make T-HEAD aclint timer more closer to the aclint spec, use
regs-names to represent the mtimecmp register, which can avoid hack
for unsupport mtime register of T-HEAD aclint timer.

Also, as T-HEAD aclint only supports mtimecmp, it is unnecessary to
implement the whole aclint spec. To make this binding T-HEAD specific,
only add reg-name for existed register. For details, see the discussion
in the last link.

Pull SoC DT updates from Arnd Bergmann:
 "There are a couple new SoCs that are supported for the first time:

   - AMD Pensando Elba is a data processing unit based on Cortex-A72 CPU
     cores

   - Sophgo makes RISC-V based chips, and we now support the CV1800B
     chip used in the milkv-duo board and the massive sg2042 chip in the
     milkv-pioneer, a 64-core developer workstation.

   - Qualcomm Snapdragon 720G (sm7125) is a close relative of Snapdragon
     7c and gets added with some Xiaomi phones

   - Renesas gains support for the R8A779F4 (R-Car S4-8) automotive SoC
     and the RZ/G3S (R9A08G045) embedded SoC.

  There are also a bunch of newly supported machines that use already
  supported chips. On the 32-bit side, we have:

   - USRobotics USR8200 is a NAS/Firewall/router based on the ancient
     Intel IXP4xx platform

   - A couple of machines based on the NXP i.MX5 and i.MX6 platforms

   - One machine each for Allwinner V3s, Aspeed AST2600, Microchip
     sama5d29 and ST STM32mp157

  The other ones all use arm64 cores on chips from allwinner, amlogic,
  freescale, mediatek, qualcomm and rockchip"

e9cdce5823 dt-bindings: timer: add imx7d compatible
Currently the dtbs_check for imx6ul generates warnings like this:

['fsl,imx7d-gpt', 'fsl,imx6sx-gpt'] is too long

The driver has no special handling for fsl,imx7d-gpt, so fsl,imx6sx-gpt is
used. Therefore make imx7d GPT compatible to the imx6sx one to fix the
warning.

4734449f73 dt-bindings: timer: Add Sophgo sg2042 CLINT timer
The clint of Sophgo's sg2042 is based off IP designed by T-HEAD, but
Sophgo changes this IP layout to fit its cpu design and is incompatible
with the standard sifive clint. The timer and ipi device are on the
different address, and can not be handled by the sifive,clint dt-bindings.

If we use the same compatible string for mswi and timer of the sg2042
clint like sifive,clint, the DT may be like this:

mswi: interrupt-controller@94000000 {
	compatible = "sophgo,sg2042-clint", "thead,c900-clint";
	interrupts-extended = <&cpu1intc 3>;
	reg = <0x94000000 0x00010000>;
};

timer: timer@ac000000 {
	compatible = "sophgo,sg2042-clint", "thead,c900-clint";
	interrupts-extended = <&cpu1intc 7>;
	reg = <0xac000000 0x00010000>;
};

Since the address of mswi and timer are different, it is hard to merge
them directly. So we need two DT nodes to handle both devices.
If we use this DT for SBI, it will parse the mswi device in the timer
initialization as the compatible string is the same, so will mswi.
As they are different devices, this incorrect initialization will cause
the system unusable.

There is a more robust ACLINT spec. can handle this situation, but
the spec. seems to be abandoned and will not be frozen in the predictable
future.

So it is not the time to add ACLINT spec in the kernel bindings. Instead,
using vendor bindings is more acceptable.

Add new vendor specific compatible strings to identify timer of sg2042
clint.

6c1561fb90 Merge tag 'soc-dt-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
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

  As usual, a lot more detail is available in the individual merge

c1362fd0f2 Merge patch series "Add Sipeed Lichee Pi 4A RISC-V board support"
Jisheng Zhang <jszhang@kernel.org> says:

Sipeed's Lichee Pi 4A development board uses Lichee Module 4A core
module which is powered by T-HEAD's TH1520 SoC. Add minimal device
tree files for the core module and the development board.

Support basic uart/gpio/dmac drivers, so supports booting to a basic
shell.

This also pulls in -rc2, because of some maintainers re-jigging that
went on in the interim in commit 80e62bc848 ("MAINTAINERS: re-sort
all entries and fields").

451d69d2f1 dt-bindings: imxgpt: add imx6ul compatible
Currently the dtbs_check for imx6ul generates warnings like this:

['fsl,imx6ul-gpt', 'fsl,imx6sx-gpt'] is too long

According to the timer-imx-gpt driver all imx6 use the same imx6dl data,
but according to the existing DTS files the imx6ul GPT IP is derived from
imx6sx. So better follow the DTS files here and make the imx6ul GPT
compatible to the imx6sl one to fix the warning.

51010c1dc4 dt-bindings: timer: rockchip: Drop superfluous rk3288 compatible
The compatible string for Rockchip RK3288 is wrongly provided in the
'enum' item, in addition to the subsequent 'const', which allows the
usage of an incorrect specification:

  compatible = "rockchip,rk3288-timer", "rockchip,rk3288-timer";

As the rk3288 string is also specified in the top-most 'const' item, the
binding already allows the usage of the correct variant:

  compatible = "rockchip,rk3288-timer";

Drop the unwanted rk3288 entry from the enum.
