The UART controllers in most Rockchip SoCs are part of power domains
that are always powered on. These always powered on power domains have
typically not been described in the device tree.
Because these power domains have been left out of the device tree there
has not been any real need to properly describe the UART controllers
power domain of Rockchip SoCs.
On Rockchip RK3528 the UART controllers are spread out among the
described PD_RKVENC, PD_VO and PD_VPU power domains. However, one UART
controller belong to an undescribed always powered on power domain.
Add support to describe an optional power-domains for the UART
controllers.

Add dedicated samsung,exynos2200-uart compatible to the dt-schema for
representing uart of the exynos2200.
Like GS101, it has a required DT property samsung,uart-fifosize and
exhibits the 32 bit register access limit, so reuse support for it.

The devlink_nl_rate_tc_bw_parse function uses a large stack array for
devlink attributes, which triggers a warning about excessive stack
usage:
net/devlink/rate.c: In function 'devlink_nl_rate_tc_bw_parse':
net/devlink/rate.c:382:1: error: the frame size of 1648 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]
Introduce a separate attribute set specifically for rate TC bandwidth
parsing that only contains the two attributes actually used: index
and bandwidth. This reduces the stack array from DEVLINK_ATTR_MAX
entries to just 2 entries, solving the stack usage issue.
Update devlink selftest to use the new 'index' and 'bw' attribute names
consistent with the YAML spec.
Example usage with ynl with the new spec:
./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \
--do rate-set --json '{
"bus-name": "pci",
"dev-name": "0000:08:00.0",
"port-index": 1,
"rate-tc-bws": [
{"index": 0, "bw": 50},

{"index": 4, "bw": 0},
{"index": 5, "bw": 0},

]
}'

--do rate-get --json '{
"bus-name": "pci",
"dev-name": "0000:08:00.0",

Document support for the I2C Bus Interface (RIIC) found on the Renesas
RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs.
The RIIC IP on these parts is similar to that on RZ/V2H(P) but supports
only four interrupts (including a combined error/event), lacks FM+ mode,
and does not require reset. Introduce a new compatible string
`renesas,riic-r9a09g077` for RZ/T2H and use it as a fallback for RZ/N2H.
Unlike earlier SoCs that use eight distinct interrupts, the RZ/T2H uses
only four. Update the binding schema to reflect this interrupt layout
and skip the `resets` property check, as it is not required on these SoCs.

RISC-V Devicetrees for v6.17
Sophgo:
For CV18xx serials:
There are three major changes. The first is to add the
RTCSYS MFD node, which provides rich control registers
for soc power management and other rich control functions;
the second is to add the reset controller node and add
related reset properties for other peripherals; the third
is to add ethernet controller related nodes to the soc
and enable ethernet device control for HuashanPi.
For SG2042:
There are three major changes. The first is to add ISA
extensions such as xtheadvector/ziccrse/zfh for cpu cores;
the second is add ethernet controller support; the third
is add two new boards EVB_V1 & EVB_V2 which use SG2042
SoC.
For SG2044:
There are many changes. The first is to add pmu
configuration; the second is to add ISA extensions
ziccrse and add missing riscv,cbop-block-size property
for cpu cores; the third is to add more peripherals
nodes for SoC after clock controller is ready, such as
MSI/PCIe/pwm/SPI-NOR etc. This PR also add HWMON MCU
device for the sophgo-srd3-10 board and reserve uart0
node for sophgo-srd3-10 board because uart0 is already
occupied by the firmware.
This PR also moves sophgo.yaml from the riscv directory
to soc/sophgo for sharing between riscv and arm. CV18xx
SoC contains a RISC-V big core and an ARM64 big core.
Moving sophgo.yaml to a shared location will help us
add support for ARM cores to the CV18xx chip in the future.

In January 2015, tracefs was created to allow access to the tracing
infrastructure without needing to compile in debugfs. When tracefs is
configured, the directory /sys/kernel/tracing will exist and tooling is
expected to use that path to access the tracing infrastructure.
To allow backward compatibility, when debugfs is mounted, it would
automount tracefs in its "tracing" directory so that tooling that had hard
coded /sys/kernel/debug/tracing would still work.
It has been over 10 years since the new interface was introduced, and all
tooling should now be using it. Start the process of deprecating the old
path so that it doesn't need to be maintained anymore.
A new config is added to allow distributions to disable automounting of
tracefs on debugfs.
If /sys/kernel/debug/tracing is accessed, a pr_warn() will trigger stating:
"NOTICE: Automounting of tracing to debugfs is deprecated and will be removed in 2030"
Expect to remove this feature in 5 years (2030).

'minItems' alone does not impose upper bound, unlike 'maxItems' which
implies lower bound. Add missing clock constraint so the list will have
exact number of items (clocks).

Remove the cdrom_mrw_exit call from unregister_cdrom, as it invokes
block commands that can fail due to a NULL pointer dereference from the
call happening too late, during the unloading of the driver (e.g.
unplugging of USB optical drives).
Instead perform the call inside cdrom_release, thus also removing the
need for the exit function pointer inside the cdrom_device_info struct.

Ftrace is tightly coupled with architecture specific code because it
requires the use of trampolines written in assembly. This means that when
a new feature or optimization is made, it must be done for all
architectures. To simplify the approach, CONFIG_HAVE_FTRACE_* configs are
added to denote which architecture has the new enhancement so that other
architectures can still function until they too have been updated.
The CONFIG_HAVE_FTRACE_MCOUNT was added to help simplify the
DYNAMIC_FTRACE work, but now every architecture that implements
DYNAMIC_FTRACE also has HAVE_FTRACE_MCOUNT set too, making it redundant
with the HAVE_DYNAMIC_FTRACE.
Remove the HAVE_FTRACE_MCOUNT config and use DYNAMIC_FTRACE directly where
applicable.

Platforms supporting direct message request v2 [1] can support secure
partitions that support multiple services. For CRB over FF-A interface,
if the firmware TPM or TPM service [1] shares its Secure Partition (SP)
with another service, message requests may fail with a -EBUSY error.
To handle this, replace the single check and call with a retry loop
that attempts the TPM message send operation until it succeeds or a
configurable timeout is reached. Implement a _try_send_receive function
to do a single send/receive and modify the existing send_receive to
add this retry loop.
The retry mechanism introduces a module parameter (`busy_timeout_ms`,
default: 2000ms) to control how long to keep retrying on -EBUSY
responses. Between retries, the code waits briefly (50-100 microseconds)
to avoid busy-waiting and handling TPM BUSY conditions more gracefully.
The parameter can be modified at run-time as such:
echo 3000 | tee /sys/module/tpm_crb_ffa/parameters/busy_timeout_ms
This changes the timeout from the default 2000ms to 3000ms.

Apple SoC device tree changes for v6.17
- Added the bindings and nodes for Apple SoC GPU. The driver itself
isn't ready for upstreaming yet due to rust dependencies but we're
confident that the bindings are stable at this point.
- Added a missing node for the touchbar framebuffer to Apple T2 device
trees, which is the BMC for some x86 Macs
- Fixed a W=1 warning by adding bit offsets to NVMEM node names. This
required a change to the generic NVMEM cell binding which will be part
of 6.17 through the NVMEM tree.

New board: FriendlyElec NanoPi M5
Camera support for the PinePhone Pro.
A bunch of cleanups to make DTC happier, fix ordering of DMA uart
channels on rk3528 and some video output enablement as well as some
button definitions.
An interesting tidbit is the reset behaviour addition in that some
boards have specific requirements as to how the PMIC needs to do the
restart. DT-maintainers did not consider the header with helper-constants
as part of the binding, so that header ended up in the Rockchip directory

Support for the AX3000 SoC, from Harshit Shah <hshah@axiado.com>:
The AX3000 is a multi-core system-on-chip featuring four ARM Cortex-A53
cores, secure vault, hardware firewall, and AI acceleration engines. This
initial support enables basic bring-up of the SoC and evaluation platform
with CPU, timer, UART, and I3C functionality.
The series begins by adding the "axiado" vendor prefix and compatible
strings for the SoC and board. It then introduces the device tree files
and minimal ARCH_AXIADO platform support in arm64.
