Sophgo:
For CV18xx serials:
Add top syscon device related DTS change, the top system
controller provides register access to configure some
misc modules, such as usb2 phy and a dma multiplexer.
For SG2042:
There are two changes. The first one is to add DTS
definition for PCIe controllers for SoC SG2042 and
boards such as Pioneerbox/EVB_V1/EVB_V2 uses SG2042.
The second one is to add DTS to support SPI-NOR flash
controllers for this SoC and the same for related boards.

Now that get_feat is in Python, we don't need to use subprocess

directly.

As we want to call Python code directly at the Sphinx extension,
convert get_feat.pl to Python.
The code was made to be (almost) bug-compatible with the Perl
version, with two exceptions:
1. Currently, Perl script outputs a wrong table if arch is set
to a non-existing value;
2. the ReST table output when --feat is used without --arch
has an invalid format, as the number of characters for the
table delimiters are wrong.
Those two bugs were fixed while testing the conversion.
Additionally, another caveat was solved:
the output when --feat is used without arch and the feature
doesn't exist doesn't contain an empty table anymore.

Merge series from Andreas Kemnade <andreas@kemnade.info>:
Add a driver for the FP9931/JD9930 regulator which provides the
comparatively high voltages needed for electronic paper displays.
Datasheet for the FP9931 is at
https://www.fitipower.com/dl/file/flXa6hIchVeu0W3K
Although it is in English, it seems to be only downloadable
from the Chinese part of that website.
For the JD9930 there can be a datasheet found at
https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/196/JD9930_2D00_0.7_2D00_JUN_2D00_2019.pdf
To simplify things, include the hwmon part directly which is only
one register read and there are not other functions besides
regulators in this chip.

Qualcomm Arm64 DeviceTree updates for v6.19
Introduce support for the Redxa Dragon Q6A development board, the Huawei
MateBoot E 2019, the Asus ZenFone 2 Laser/Selfie, the MSM8937 platform
and the Xiaomo Redmi 3S device based on it.
SoC dtsi files for Agatti, Hamoa, Kodiak, Monaco, Purwa, and Talos, are
renamed in order to better facilitate the addition of new boards on the
various SKUs of these.
Cooling maps are introduced for the CPU cores in IPQ5424, and the
network subsystem clock controller is added.
On Lemans, RTC is enabled, the EVK fan controller is described and a
camera mezzanine overlay is introduced.
Touchscreen support is added to the BQ Aquaris M5, and the touchscreen
from Samsung Galaxy Core Prime is moved to the common platform to
benefit the other devices sharing common definitions.
On Agatti two more UARTs are described, as well as APR and the related audio
services, and the LPASS LPI pin controller. The RB1 board gets HDMI
autio playback support.
On Kodiak-based targets, Fairphone FP5 gains definitions of the UW camera
actuator, regulator for the ToF sensor, and haptic module. The SHIFT
SHIFTphone 8 gains RGB and flash LEDs, and Venus support. The Rb3Gen2
development board gets QUP firmware path defined, to support dynamic
loading of the serial engine firmware. Kodiak also gains Coresight
devices for AOSS and QDSS blocks.
Display support is added for the Talos platform, and enabled on the Ride
board. Talos also gains the definitions to scale DDR and L3
interconnects.
On SC8280XP, the camera privacy indicator on Lenovo Thinkpad X13s is
connected to the camera stack. Off-by-one GPI DMA channels are
corrected.
The SDM845-based LG and OnePlus custom defined rmtfs guard pages are
replaced with the inline-support for guard pages.
SDX75 DWC3 node is flattened and marked for USB role switching.
On SM8550, the camera subsystem and the S5K3M5 camera sensor is
introduced for the QRD, and an overlay for the "Rear Camera Card" for
the Hardware Development Kit (HDK) is introduced.
USB support is introduce for the SM8750 platform, and enabled in the MTP
and QRD devices.
On Hamoa, like on other devices the Asus Zenbook A14 definition of the
eDP panel is reworked to support both LCD and OLED configurations. WiFi
and Bluetooth is also enabled on the A14. The CRD gains support for
controlling charge limits.
The refgen regulator supplying DSI is defined and wired up on a variety
of platforms.

MediaTek ARM64 Device Tree updates
This adds support for new boards and variants based on different
already supported MediaTek SoCs, and improves support for current
boards.
In particular:
- New machines:
- MT7988 BananaPi R4 Pro eMMC and SD router board with support
for both Key-M and Key-E M.2 slots through DTB Overlays
- MT8370 Grinn GenioSBC-510 (GenioSOM-510 + GenioBoard Edge AI)
- MT8390 Grinn GenioSBC-700 (GenioSOM-700 + GenioBoard Edge AI)
- New variant: MT8395 MediaTek Genio 1200 EVK with UFS
...preparation for new SoCs (MT8196 Kompanio Ultra, a clone of the
MT6991 Dimensity 9400, and MT6878 Dimensity 7300) with the
addition of GCE/PIO definitions
...improvements for already supported SoCs and machines:
- MT7622/7981b/7986a/7988a gain support for reading SoC UUID from
eFuse, used to generate a persistent MAC address on boards that
don't have any factory-assigned addresses.
- MT7986 BananaPi R3 gets changes to its default fan PWM speed to
improve compatibility with cheaper fans (usually coming with the
heatsink+fan combos)
- The MT7981b OpenWRT One router sees general support improvements
with the enablement of its UART-0 console and correct pinmuxing
for the same, addition of reserved memory for Trusted Firmware A,
its SPI NOR Flash (for recovery system, WiFi eeprom data and ETH
MAC address from factory), and board LEDs.
- MT8365 gets support for its Mali G52 MC1 GPU, which gets enabled
in the MediaTek Genio 350 EVK board
...and a dt-bindings warning fix for MT8183 machines through trivial
changes to rename the audiosys and afe nodes to reflect bindings.

The Ayaneo 3 features hot-swappable controller modules. The ejection
and management is done through HID. However, after ejecting the modules,
the controller needs to be power cycled via the EC to re-initialize.
For this, the EC provides a variable that holds whether the left or
right modules are connected, and a power control register to turn
the controller on or off. After ejecting the modules, the controller
should be turned off. Then, after both modules are reinserted,
the controller may be powered on again to re-initialize.
This patch introduces two new sysfs attributes:
- `controller_modules`: a read-only attribute that indicates whether
the left and right modules are connected (none, left, right, both).
- `controller_power`: a read-write attribute that allows the user
to turn the controller on or off (with '1'/'0').
Therefore, after ejection is complete, userspace can power off the
controller, then wait until both modules have been reinserted
(`controller_modules` will return 'both') to turn on the controller.

First batch of ASPEED Arm devicetree changes for 6.19
Significant changes:
- The IBM Power11 FSI DTSIs have been rearranged to accommodate new systems
New platforms:
- IBM Balcones
The Balcones system is similar to Bonnell but with a POWER11 processor.
Like POWER10, the POWER11 is a dual-chip module, so a dual chip FSI
tree is needed.
- Meta Yosemite5
The Yosemite5 platform provides monitoring of voltages, power,
temperatures, and other critical parameters across the motherboard,
CXL board, E1.S expansion board, and NIC components.
Updated platforms:
- clemente (Meta): LEDs, shunt resistor configuration
- santabarbara (Meta): AMD APML, EEPROMs, LEDs, GPIO line names, MCTP for NICs
There are a scattering of one-off changes and devicetree cleanups for other

Tenstorrent device tree for v6.19
Add Tenstorrent as a vendor and enable support for the Blackhole SoC
in Blackhole P100 and P150 PCIe cards. The SoC contains four RISC-V
CPU tiles consisting of 4x SiFive X280 cores.
There is a virtual UART implemented in OpenSBI firmware that allows a
console program on the PCIe host to communicate through shared memory
with Linux running on the Blackhole card.

IIO: New device support, features and cleanup for 6.19
The usual bunch of new device support, but also quite a bit of cleanup
of the core and older drivers which is always good to see.
New device support
------------------
adi,ad4080
- Add support for AD4081, AD4083, AD4084, AD4086 and AD4087 ADCs with
slightly different features to existing supported parts (max CNV clock
count, resolution etc)
adi,adxl380
- Add support for ADXL318 and ADXL319 which have reduced functionality
compared to other supported parts, particularly around event detection.
aosong,adp810
- New driver for this differential pressure and temperature sensor.
aspeed,adc
- Add support for the AST2700 SoC ADCs which differ in small ways from
already supported parts.
bosch,sm330
- New driver for this IMU (accelerometer + gyroscop) with I2C and SPI bus
support.
invensense,icm45600
- New driver for this family of IMUs with sub drivers for accelerometer
and gyroscope elements. I2C, I3C and SPI busses all supported.
* Supports ICM45605, ICM45606, ICM45608, ICM45634, ICM45686, ICM45687,
ICM45688P, ICM45689.
* Support basic features and FIFO.
maxim,max14001
- New driver for the MAX14001 and MAX14002 ADCs.
renesas,rzt2h
- New driver supporting the RZ/T2H and RZ/N2H ADCs found in various SoCs.
renesas,rznl
- New driver supporting the RZ/NL ADC found in various SoCs.
Features
--------
adi,ad5446
- Add a DT binding doc for the 29 variants currently covered by the driver.
- Add adi,ad5542 which is compatiable with the adi,ad5542a which was
already supported.
bosch,bma220
- I2C support including an I2C bus watchdog.
- Power supply control
- Data ready trigger.
- Low pass filter control.
- Debugfs register access.
- Add Petre Rodan as a maintainer of this driver (thanks!)
bosch,bmi270
- Add support for motion events.
fsl,mpl3115
- Add a dataready trigger and related sampling frequency control.
- Add threshold events.
infineon,dps310
- Add a specific device tree binding.
maxim,max30100
- Allow control of LED pulse-width in dt-binding. Optimum value depends
on physical characteristics of the device which contains this sensor.
mediatek,mt2701
- Add dt compatible for the mt8189.
rockchip,saradc
- Add rk3506 compatible which is functionally the same as the already
supported rk3528 (which is therefore the fallback)
st,lsm6dsx
- Make sampling more flexible when both fifo and events are of interest
by decoupling the FIFO fill rate from actual sampling.
Cleanup and minor fixes
-----------------------
core
- Document and add might_sleep() to iio_push_to_buffers_with_ts_unaligned()
as it allocates a buffer, typically just on 1st call.
- Add documentation for iio_push_to_buffers_with_ts() which is being used
to replace iio_push_to_buffers_with_timestamp() in new code as it
validates the buffer size. Make the deprecation of the old function
clear.
- Document that the store_to() callback in struct iio_buffer_access_funcs
may be called from contexts that cannot sleep.
- Document that the cb() provided to a callback buffer may be called
from contexts that cannot sleep.
- Cleanup up industrialio-backend.c comments.
- Call mutex_destroy() in cleanup of buffers.
- Call device_initialize() later to avoid having to call device_put()
before configuration is otherwise complete.
- Use mutex_init_with_key() to replace opencoded version.
- Use dma_buf_unmap_attachment_unlocked() to replace opencoded version.
- Reorder Makefile for pressure sensors.
various
- Uses sysfs_emit() to replace sprintf() in read_label() and other
callbacks that typically are used to write data to sysfs buffers.
- Switch to REGCACHE_MAPLE in various drivers.
adi,docs
- Fix up formatting of cross references and other kernel-doc issues.
adi,ad4080
- Fix wrong masking of product IDs.
adi,ad5446
- Use DMA safe buffers as needed for SPI.
- Drop a duplicate device chip specific data structure where two parts
are functionally identical.
- Fail probe if reference is not available.
- Split up the massive array of chip type specific structures into
separate structures as this tends to be easier to read and maintain.
- Add explicit of_device_id entries for all supported parts.
- Split I2C and SPI parts away from core to avoid ifdef complexity.
- Switch to devm_mutex_init().
- Make use of guard() to simplify code.
- Applying IWYU principles and reorder headers.
- Various other minor cleanup.
adi,ad7124
- Add debugfs to support single cycle mode, typically only used for cases
such as validate performance of the ADC.
- Various other minor cleanup including removing some layers of indirection
that weren't necessary.
- Add extended attributes to the temperature channel which follows the same
signal path as other channels.
- Replace the setup register allocation strategy with a simpler more
predictable one (a fix for OOB from this code follows later in this pull
request).
adi,adxl345
- Ensure dt-binding allows for both interrupt wired at the same time.
arm,scmi
- Replace const_ilog2() with the resulting value which ends up simpler
to read.
bosch,bma220
- Add correct SPI mode specification to the device tree binding.
- Fix up interrupt type in dt binding example to match that the driver
expects.
- Relax hard constraint on matching chip ID with a message only so as to
enable fallback DT compatibles to work.
- Use local struct device *dev to replaces lots of indirect look ups.
- Improve includes on approximate IWYU basis.
- Explicit of_match_table.
- Reset some registers during probe.
- Move to regmap.
- Ensure a timestamp is available when filling the buffer by using a
locally acquired one rather than relying on trigger top half running.
- Add a utility function to search value pair tables for a match.
- Various other minor improvements.
- Move code to avoid a false dependency of the core code on the I2C module.
bosch,bma400
- Improve register and field naming + organization. Use with FIELD_GET()
and FIELD_PREP() to allow dropping of shift defines.
- Use macros to define event related fields.
- Switch to an address lookup based on an index variable to replace lots of
very similar register macros.
- Rename activity_event_en() to generic_event_en() to better reflect what
it does.
- Improve comments around interrupt register handling.
fsl,mpl3115
- Factor out code for triggered buffer data collection.
- Use more consistent register field naming style.
- Use get_unaligned_be24() to get the pressure.
invensense,mpu6050
- Drop false requirement in DT binding for the interrupt. The driver will
be able to do less if one is not provided, but some features are still
available.
invensense,icm45600_i3c
- Fix missing return on failure to match part.
linear,ltc2688
- Use devm_mutex_init() so mutex_destroy() is called in tear down path.
- Use guard() to simplify lock handling in error return paths.
qcom,vadc
- Fix up some kernel-doc related warnings.
rohm,bd79112 and bd79124
- Use regmap_reg_range() helper to set the ranges.
st,lsm6dsx
- Fix units of ODR in structure documentation.
ti,am335x
- Add range checks to avoid a compiler warning.
ti,pac1934
- Switch to system_percpu_wq.
Various other minor typo fixes etc.

Update the bindings to support reading ID state and VBUS, as per the
HD3SS3220 data sheet. The ID pin is kept high if VBUS is not at VSafe0V and
asserted low once VBUS is at VSafe0V, enforcing the Type-C requirement that
VBUS must be at VSafe0V before re-enabling VBUS.
Add id-gpios property to describe the input gpio for USB ID pin.

Add device tree binding support for the USB3.2 Gen2 controller on Renesas
RZ/V2H(P) and RZ/V2N SoCs. The USB3.2 IP on these SoCs is identical to
that found on the RZ/G3E SoC.
Add new compatible strings "renesas,r9a09g056-xhci" for RZ/V2N and
"renesas,r9a09g057-xhci" for RZ/V2H(P). Both variants use
"renesas,r9a09g047-xhci" as a fallback compatible to indicate hardware
compatibility with the RZ/G3E implementation.
Update the title to be more generic as it now covers multiple SoC
families beyond just RZ/G3E.

Currently, user can only specify cgroup to the tracer's thread the
following ways:
`-C[cgroup]`
`-C[=cgroup]`
`--cgroup[=cgroup]`
If user tries to specify cgroup as `-C [cgroup]` or `--cgroup [cgroup]`,
the parser silently fails and rtla's cgroup is used for the tracer
threads.
To make interface more user-friendly, allow user to specify cgroup in
the aforementioned way, i.e. `-C [cgroup]` and `--cgroup [cgroup]`.
Refactor identical logic between -t/--trace and -C/--cgroup into a
common function.
Change documentation to reflect this user interface change.

Setting KVM_CAP_S390_USER_OPEREXEC will forward all operation
exceptions to user space. This also includes the 0x0000 instructions
managed by KVM_CAP_S390_USER_INSTR0. It's helpful if user space wants
to emulate instructions which do not (yet) have an opcode.
While we're at it refine the documentation for
KVM_CAP_S390_USER_INSTR0.

There are two kernel-doc like descriptions at cper, which is used
by other parts of cper and on ghes driver. They both have kernel-doc
like descriptions.
Change the tags for them to be actual kernel-doc tags and add them
to the driver-api documentaion at the UEFI section.

swp_l4_csum_mode controls how L4 transmit checksums are computed when
using Software Parser (SWP) hints for header locations.
Supported values:
1. default: device will choose between full_csum or l4_only. Driver
will discover the device's choice during initialization.
2. full_csum: calculate L4 checksum with the pseudo-header.
3. l4_only: calculate L4 checksum without the pseudo-header. Only
available when swp_l4_csum_mode_l4_only is set in
mlx5_ifc_nv_sw_offload_cap_bits.
Note that 'default' might be returned from the device and passed to
userspace, and it might also be set during a
devlink_param::reset_default() call, but attempts to set a value of
default directly with param-set will be rejected.
The l4_only setting is a dependency for PSP initialization in
mlx5e_psp_init().

Support querying and resetting to default param values.
Introduce two new devlink netlink attrs:
DEVLINK_ATTR_PARAM_VALUE_DEFAULT and
DEVLINK_ATTR_PARAM_RESET_DEFAULT. The former is used to contain an
optional parameter value inside of the param_value nested
attribute. The latter is used in param-set requests from userspace to
indicate that the driver should reset the param to its default value.
To implement this, two new functions are added to the devlink driver
api: devlink_param::get_default() and
devlink_param::reset_default(). These callbacks allow drivers to
implement default param actions for runtime and permanent cmodes. For
driverinit params, the core latches the last value set by a driver via
devl_param_driverinit_value_set(), and uses that as the default value
for a param.
Because default parameter values are optional, it would be impossible
to discern whether or not a param of type bool has default value of
false or not provided if the default value is encoded using a netlink
flag type. For this reason, when a DEVLINK_PARAM_TYPE_BOOL has an
associated default value, the default value is encoded using a u8
type.

This is a follow up of commit aa251c84636c ("tcp: fix too slow
tcp_rcvbuf_grow() action") which brought again the issue that I tried
to fix in commit 65c5287892e9 ("tcp: fix sk_rcvbuf overshoot")
We also recently increased tcp_rmem[2] to 32 MB in commit 572be9bf9d0d
("tcp: increase tcp_rmem[2] to 32 MB")
Idea of this patch is to not let tcp_rcvbuf_grow() grow sk->sk_rcvbuf
too fast for small RTT flows. If sk->sk_rcvbuf is too big, this can
force NIC driver to not recycle pages from their page pool, and also
can cause cache evictions for DDIO enabled cpus/NIC, as receivers
are usually slower than senders.
Add net.ipv4.tcp_rcvbuf_low_rtt sysctl, set by default to 1000 usec (1 ms)
If RTT if smaller than the sysctl value, use the RTT/tcp_rcvbuf_low_rtt
ratio to control sk_rcvbuf inflation.
Tested:
Pair of hosts with a 200Gbit IDPF NIC. Using netperf/netserver
Client initiates 8 TCP bulk flows, asking netserver to use CPU #10 only.
super_netperf 8 -H server -T,10 -l 30
On server, use perf -e tcp:tcp_rcvbuf_grow while test is running.
Before:
sysctl -w net.ipv4.tcp_rcvbuf_low_rtt=1
perf record -a -e tcp:tcp_rcvbuf_grow sleep 30 ; perf script|tail -20|cut -c30-230

We can see sk_rcvbuf values are much smaller, and that rtt_us (estimation of rtt
from a receiver point of view) is kept small, instead of being bloated.
No difference in throughput.

sysctl_tcp_moderate_rcvbuf is only used from tcp_rcvbuf_grow().
Move it to netns_ipv4_read_rx group.
Remove various CACHELINE_ASSERT_GROUP_SIZE() from netns_ipv4_struct_check(),
as they have no real benefit but cause pain for all changes.

Add a sysfs entry /sys/kernel/kexec_crash_cma_ranges to expose all CMA
crashkernel ranges.
This allows userspace tools configuring kdump to determine how much memory
is reserved for crashkernel. If CMA is used, tools can warn users when
attempting to capture user pages with CMA reservation.
The new sysfs hold the CMA ranges in below format:
cat /sys/kernel/kexec_crash_cma_ranges
100000000-10c7fffff
The reason for not including Crash CMA Ranges in /proc/iomem is to avoid
conflicts. It has been observed that contiguous memory ranges are
sometimes shown as two separate System RAM entries in /proc/iomem. If a
CMA range overlaps two System RAM ranges, adding crashk_res to /proc/iomem
can create a conflict. Reference [1] describes one such instance on the
PowerPC architecture.
