Monitor synthesis from deterministic automaton and linear temporal logic
have a lot in common. Therefore a single document should describe both.
Change da_monitor_synthesis.rst to monitor_synthesis.rst. LTL monitor
synthesis will be added to this file by a follow-up commit.
This makes the diff far easier to read. If renaming and adding LTL info is
done in a single commit, git wouldn't recognize it as a rename, but a file
removal and a file addition.
While at it, correct the old dot2k commands to the new rvgen commands.

The logic there which adds a dependency note to Sphinx cache

With further testing, directly using the spi-sg2044-nor driver on SG2042
does not work. SG2042 is found to lack full compatibility with SG2044.
SG2044 has OPT register and it's necessary to write but SG2042 does not.
Due to other possible hardware detail differences, it is better
to bind SG2042 independently.

Thanks to the meta buffer infrastructure, metadata-compressed inodes are
just read from the metabox inode instead of the blockdevice (or backing
file) inode.
The same is true for shared extended attributes.
When metadata compression is enabled, inode numbers are divided from
on-disk NIDs because of non-LTS 32-bit application compatibility.

Immutable branch between MFD, GPIO, Power and SoC due for the v6.17 merge window

The RK806 PMIC allows to configure its reset/restart behavior whenever
the PMIC is reset either programmatically or via some external pins
(e.g. PWRCTRL or RESETB).
The following modes exist:
- 0; restart PMU,
- 1; reset all power off reset registers and force state to switch to
ACTIVE mode,
- 2; same as mode 1 and also pull RESETB pin down for 5ms,
For example, some hardware may require a full restart (mode 0) in order
to function properly as regulators are shortly interrupted in this mode.
This is the case for RK3588 Jaguar and RK3588 Tiger which have a
companion microcontroller running on an independent power supply and
monitoring the PMIC power rail to know the state of the main system.
When it detects a restart, it resets its own IPs exposed to the main
system as if to simulate its own reset. Failing to perform this fake
reset of the microcontroller may break things (e.g. watchdog not
automatically disabled, buzzer still running until manually disabled,
leftover configuration from previous main system state, etc...).
Some other systems may be depending on the power rails to not be
interrupted even for a small amount of time[1].
This allows to specify how the PMIC should perform on the hardware level
and may differ between hardware designs, so a DT property seems
warranted. I unfortunately do not see how this could be made generic
enough to make it a non-vendor property.

Document why the binding uses oneOf when specifying just one of the
interrupt properties is supposed to be enough.
dtschema's fixups.py has special treatment of the interrupts and
interrupts-extended properties, but that appears to work at the top
level only. Elsewhere, an explicit oneOf is required.

commit b0a5cde57cf1 ("dt-bindings: mfd: Explain lack of child dependency
in simple-mfd") pointed out that it's a mistake for a child device of
a simple MFD device to depend on the simple MFD device's clock resources.
fsl,imx8qxp-csr.yaml happens to make that mistake. To fix that, remove
fsl,imx8qxp-csr.yaml and use "simple-pm-bus" and "syscon" as the CSR node's
compatible strings in the examples of fsl,imx8qxp-pixel-link-msi-bus.yaml
to replace the wrong compatible strings which include "simple-mfd" and
"fsl,imx8qxp-mipi-lvds-csr". Since fsl,imx8qxp-pixel-link-msi-bus.yaml
as the last user of the CSR compatible strings no longer uses them, it's
safe to remove the fsl,imx8qxp-csr.yaml binding documentation.

The GPIO controllers in most Rockchip SoCs are part of power domains
that are always powered on, i.e. PD_BUS or PD_PMU. 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 GPIO controllers
power domain.
On RK3528 the GPIO controllers are spread out among the described
PD_RKVENC, PD_VO and PD_VPU power domains. However, one GPIO controller
belong to an undescribed always powered on power domain.

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 \

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.

In preparation for adding more validation checks, move the `$ref` for
'i2c-controller.yaml' to the end of the file. Also, relocate the
conditional check for 'resets' into the 'allOf' block.

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).
