Pull ARM SoC DT updates from Arnd Bergmann:
"The devicetree changes contain exactly 1000 non-merge changesets,
including a number of new arm64 SoC variants from Qualcomm and Apple,
as well as the Renesas r9a07g043f/u chip in both arm64 and riscv
variants.
While we have occasionally merged support for non-arm SoCs in the
past, this is now the normal path for riscv devicetree files.
The most notable changes, by SoC platform, are:
- The Apple T6000 (M1 Pro), T6001 (M1 Max) and T6002 (M1 Ultra) chips
now have initial support. This is particularly nice as I am typing
this on a T6002 Mac Studio with only a small number of driver
patches.
- Qualcomm MSM8996 Pro (Snapdragon 821), SM6115 (Snapdragon 662),
SM4250 (Snapdragon 460), SM6375 (Snapdragon 695), SDM670
(Snapdragon 670), MSM8976 (Snapdragon 652) and MSM8956 (Snapdragon
650) are all mobile phone chips that are closely related to others
we already support.
Adding those helps support more phones and we add several models
from Sony (Xperia 10 IV, 5 IV, X, and X compact), OnePlus (One, 3,
3T, and Nord N100), Xiaomi (Poco F1, Mi6), Huawei (Watch) and
Google (Pixel 3a).
There are also new variants of the Herobrine and Trogdor chromebook
motherboards. SA8540P is an automotive SoC used in the Qdrive-3
development platform
- Rockchips gains no new SoC variants, but a lot of new boards: three
mobile gaming systems based on RK3326 Odroid-Go/rg351 family, two
more Anbernic gaming systems based on RK3566 and a number of other
RK356x based single-board computers.
- Renesas RZ/G2UL (r9a07g043) was already supported for arm64, but as
the newly added RZ/Five is based on the same design, this now gets
reorganized in order to share most of the dts description between
the two and add the RZ/Five SMARC EVK board support.
Aside from that, there are the usual changes all over the tree:
- New boards on other platforms contain two ASpeed BMC users, two
Broadcom based Wifi routers, Zyxel NSA310S NAS, the i.MX6 based
Kobo Aura2 ebook reader, two i.MX8 based development boards, two
Uniphier Pro5 development boards, the STM32MP1 testbench board from
DHCOR, the TI K3 based BeagleBone AI-64 board, and the Mediatek
Helio X10 based Sony Xperia M5 phone.
- The Starfive JH7100 source gets reorganized in order to support the
VisionFive V1 board.
- Minor updates and cleanups for Intel SoCFPGA, Marvell PXA168, TI,
ST, NXP, Apple, Broadcom, Juno, Marvell MVEBU, at91, nuvoton,
Tegra, Mediatek, Renesas, Hisilicon, Allwinner, Samsung, ux500,
spear, ... The treewide cleanups now have a lot of fixes for cache
nodes and other binding violoations.
- Somewhat larger sets of reworks for NVIDIA Tegra, Qualcomm and
Renesas platforms, adding a lot more on-chip device support
- A rework of the way that DTB overlays are built"

Pull ARM SoC driver updates from Arnd Bergmann:
"There are few major updates in the SoC specific drivers, mainly the
usual reworks and support for variants of the existing SoC. While this
remains Arm centric for the most part, the branch now also contains
updates to risc-v and loongarch specific code in drivers/soc/.
Notable changes include:
- Support for the newly added Qualcomm Snapdragon variants (MSM8956,
MSM8976, SM6115, SM4250, SM8150, SA8155 and SM8550) in the soc ID,
rpmh, rpm, spm and powerdomain drivers.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"The highlights this time are support for dynamically enabling and
disabling Clang's Shadow Call Stack at boot and a long-awaited
optimisation to the way in which we handle the SVE register state on
system call entry to avoid taking unnecessary traps from userspace.
Summary:
ACPI:
- Enable FPDT support for boot-time profiling
- Fix CPU PMU probing to work better with PREEMPT_RT
- Update SMMUv3 MSI DeviceID parsing to latest IORT spec
- APMT support for probing Arm CoreSight PMU devices
CPU features:
- Advertise new SVE instructions (v2.1)
- Advertise range prefetch instruction
- Advertise CSSC ("Common Short Sequence Compression") scalar
instructions, adding things like min, max, abs, popcount
- Enable DIT (Data Independent Timing) when running in the kernel
- More conversion of system register fields over to the generated
header
CPU misfeatures:
- Workaround for Cortex-A715 erratum #2645198
Dynamic SCS:
- Support for dynamic shadow call stacks to allow switching at
runtime between Clang's SCS implementation and the CPU's pointer
authentication feature when it is supported (complete with scary
DWARF parser!)
Tracing and debug:
- Remove static ftrace in favour of, err, dynamic ftrace!
- Seperate 'struct ftrace_regs' from 'struct pt_regs' in core ftrace
and existing arch code
- Introduce and implement FTRACE_WITH_ARGS on arm64 to replace the
old FTRACE_WITH_REGS
- Extend 'crashkernel=' parameter with default value and fallback to
placement above 4G physical if initial (low) allocation fails
SVE:
- Optimisation to avoid disabling SVE unconditionally on syscall
entry and just zeroing the non-shared state on return instead
Exceptions:
- Rework of undefined instruction handling to avoid serialisation on
global lock (this includes emulation of user accesses to the ID
registers)
Perf and PMU:
- Support for TLP filters in Hisilicon's PCIe PMU device
- Support for the DDR PMU present in Amlogic Meson G12 SoCs
- Support for the terribly-named "CoreSight PMU" architecture from
Arm (and Nvidia's implementation of said architecture)
Misc:
- Tighten up our boot protocol for systems with memory above 52 bits
physical
- Const-ify static keys to satisty jump label asm constraints
- Trivial FFA driver cleanups in preparation for v1.1 support
- Export the kernel_neon_* APIs as GPL symbols
- Harden our instruction generation routines against instrumentation
- A bunch of robustness improvements to our arch-specific selftests
- Minor cleanups and fixes all over (kbuild, kprobes, kfence, PMU, ...)"

git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:
- Add NMI-safe SRCU reader API. It uses atomic_inc() instead of
this_cpu_inc() on strong load-store architectures.
- Introduce new console_list_lock to synchronize a manipulation of the
list of registered consoles and their flags.
This is a first step in removing the big-kernel-lock-like behavior of
console_lock(). This semaphore still serializes console->write()
calbacks against:
- each other. It primary prevents potential races between early
and proper console drivers using the same device.
- suspend()/resume() callbacks and init() operations in some
drivers.
- various other operations in the tty/vt and framebufer
susbsystems. It is likely that console_lock() serializes even
operations that are not directly conflicting with the
console->write() callbacks here. This is the most complicated
big-kernel-lock aspect of the console_lock() that will be hard
to untangle.
- Introduce new console_srcu lock that is used to safely iterate and
access the registered console drivers under SRCU read lock.
This is a prerequisite for introducing atomic console drivers and
console kthreads. It will reduce the complexity of serialization
against normal consoles and console_lock(). Also it should remove the
risk of deadlock during critical situations, like Oops or panic, when
only atomic consoles are registered.
- Check whether the console is registered instead of enabled on many
locations. It was a historical leftover.
- Cleanly force a preferred console in xenfb code instead of a dirty
hack.
- A lot of code and comment clean ups and improvements.

Pull unsigned-char conversion from Jason Donenfeld:
"Enable -funsigned-char and fix code affected by that flag.
During the 6.1 cycle, several patches already made it into the tree,
which were for code that was already broken on at least one
architecture, where the naked char had a different sign than the code
author anticipated, or were part of some bug fix for an existing bug
that this initiative unearthed.
These 6.1-era fixes are:
648060902aa3 ("MIPS: pic32: treat port as signed integer")
5c26159c97b3 ("ipvs: use explicitly signed chars")
e6cb8769452e ("wifi: airo: do not assign -1 to unsigned char")
937ec9f7d5f2 ("staging: rtl8192e: remove bogus ssid character sign test")
677047383296 ("misc: sgi-gru: use explicitly signed char")
50895a55bcfd ("ALSA: rme9652: use explicitly signed char")
ee03c0f200eb ("ALSA: au88x0: use explicitly signed char")
835bed1b8395 ("fbdev: sisfb: use explicitly signed char")
50f19697dd76 ("parisc: Use signed char for hardware path in pdc.h")
66063033f77e ("wifi: rt2x00: use explicitly signed or unsigned types")
Regarding patches in this pull:
- There is one patch in this pull that should have made it to you
during 6.1 ("media: stv0288: use explicitly signed char"), but the
maintainer was MIA during the cycle, so it's in here instead.
- Two patches fix single architecture code affected by unsigned char
("perf/x86: Make struct p4_event_bind::cntr signed array" and
"sparc: sbus: treat CPU index as integer"), while one patch fixes
an unused typedef, in case it's ever used in the future ("media:
atomisp: make hive_int8 explictly signed").
- Finally, there's the change to actually enable -funsigned-char
("kbuild: treat char as always unsigned") and then the removal of
some no longer useful !__CHAR_UNSIGNED__ selftest code ("lib:
assume char is unsigned").
The various fixes were found with a combination of diffing objdump
output, a large variety of Coccinelle scripts, and plain old grep. In
the end, things didn't seem as bad as I feared they would. But of
course, it's also possible I missed things.
However, this has been in linux-next for basically an entire cycle
now, so I'm not overly worried. I've also been daily driving this on
my laptop for all of 6.1. Still, this series, and the ones sent for
6.1 don't total in quantity to what I thought it'd be, so I will be on
the lookout for breakage.
We could receive a few reports that are quickly fixable. Hopefully we
won't receive a barrage of reports that would result in a revert. And
just maybe we won't receive any reports at all and nobody will even
notice. Knock on wood"

Pull RCU updates from Paul McKenney:
- Documentation updates. This is the second in a series from an ongoing
review of the RCU documentation.
- Miscellaneous fixes.
- Introduce a default-off Kconfig option that depends on RCU_NOCB_CPU
that, on CPUs mentioned in the nohz_full or rcu_nocbs boot-argument
CPU lists, causes call_rcu() to introduce delays.
These delays result in significant power savings on nearly idle
Android and ChromeOS systems. These savings range from a few percent
to more than ten percent.
This series also includes several commits that change call_rcu() to a
new call_rcu_hurry() function that avoids these delays in a few
cases, for example, where timely wakeups are required. Several of
these are outside of RCU and thus have acks and reviews from the
relevant maintainers.
- Create an srcu_read_lock_nmisafe() and an srcu_read_unlock_nmisafe()
for architectures that support NMIs, but which do not provide
NMI-safe this_cpu_inc(). These NMI-safe SRCU functions are required
by the upcoming lockless printk() work by John Ogness et al.
- Changes providing minor but important increases in torture test
coverage for the new RCU polled-grace-period APIs.
- Changes to torturescript that avoid redundant kernel builds, thus
providing about a 30% speedup for the torture.sh acceptance test.

TCAN4X5X_ERROR_STATUS is not a status register that needs clearing
during interrupt handling. Instead this is a masking register that masks
error interrupts. Writing TCAN4X5X_CLEAR_ALL_INT to this register
effectively masks everything.
Rename the register and mask all error interrupts only once by writing
to the register in tcan4x5x_init.

Register 0x824 TCAN4X5X_MCAN_INT_REG is a read-only register. Any writes
to this register do not have any effect.
Remove this write. The m_can driver aldready clears the interrupts in
m_can_isr() by writing to M_CAN_IR which is translated to register
0x1050 which is a writable version of this register.

For peripheral devices the m_can_rx_handler is called directly after
setting cdev->irqstatus. This means we don't have to read the irqstatus
again in m_can_rx_handler. Avoid this by adding a parameter that is
false for direct calls.

The TXFQS register is read first to check if the fifo is full and then
immediately again to get the putidx. This is unnecessary and adds
significant overhead if read requests are done over a slow bus, for
example SPI with tcan4x5x.
Add a variable to store the value of the register. Split the
m_can_tx_fifo_full function into two to avoid the hidden m_can_read call
if not needed.

When we try to access the mcan message ram addresses during the probe,
hclk is gated by any other drivers or disabled, because of that probe
gets failed.
Move the mram init functionality to mcan chip config called by
m_can_start from mcan open function, by that time clocks are
enabled.

The iface field of struct gs_can is only used to retrieve the
usb_device which is already available in gs_can::udev.
Replace each occurrence of interface_to_usbdev(dev->iface) with
dev->udev. This done, remove gs_can::iface.

ES58x devices report below product information through a custom usb
string:
* the firmware version
* the bootloader version
* the hardware revision
Parse this string, store the results in struct es58x_dev, export:
* the firmware version through devlink's "fw" name
* the bootloader version through devlink's "fw.bootloader" name
* the hardware revisionthrough devlink's "board.rev" name
Those devlink entries are not critical to use the device, if parsing
fails, print an informative log message and continue to probe the
device.
In addition to that, use usb_device::serial to report the device
serial number.

Add support for devlink port which extends the devlink support to the
network interface level. For now, the etas_es58x driver will only rely
on the default features that devlink port has to offer and not
implement additional feature ones.

IMX93 do not contain a GPR to config the stop mode, it will set
the flexcan into stop mode automatically once the ARM core go
into low power mode (WFI instruct) and gate off the flexcan
related clock automatically. But to let these logic work as
expect, before ARM core go into low power mode, need to make
sure the flexcan related clock keep on.
To support stop mode and wakeup feature on imx93, this patch
add a new fsl_imx93_devtype_data to separate from imx8mp.
