Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct iqs62x_fw_blk.

There are two types of STM32 timers that may have:
- a global interrupt line
- 4 dedicated interrupt lines.
Those interrupts are optional as defined in the dt-bindings. Enforce checks

Optionally get them here, to be used by child devices.

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.
Update the wcd934x to use the more modern data structure.

At the moment we allow the AXP15060 and the AXP806 PMICs to omit the
interrupt line to the SoC, and we skip registering the PEK (power key)
driver in this case, since that crashes when no IRQ is described in the
DT node.
The IRQ pin potentially not being connected to anything does affect more
PMICs, though, and the PEK driver is not the only one requiring an
interrupt: at least the AC power supply driver crashes in a similar
fashion.
Generalise the handling of AXP MFD devices when the platform tables
describe no interrupt, by allowing each device to specify an alternative
MFD list for this case. If no specific alternative is specified, we go
with the safe default of "just the regulators", which matches the current
situation.
This enables new devices using the AXP313a PMIC, but not connecting the
IRQ pin.

Upon additional review, the new fast path in adiantum_finish() is
missing the call to flush_dcache_page() that scatterwalk_map_and_copy()
was doing. It's apparently debatable whether flush_dcache_page() is
actually needed, as per the discussion at
https://lore.kernel.org/lkml/YYP1lAq46NWzhOf0@casper.infradead.org/T/#u.
However, it appears that currently all the helper functions that write
to a page, such as scatterwalk_map_and_copy(), memcpy_to_page(), and
memzero_page(), do the dcache flush. So do it to be consistent.

This is a very quiet release for SPI, we've got cleanups and minor fixes
but only a few new driver specific features. The bulk of the changes in
terms of diffstat are the cleanups, plus one bit of performance work for
McSPI.
- Conversions to use devm_clk_get_enabled() and to remove outdated
terms for controller and device.
- Device mode support for the Renesas CSI.
- Cleanups and improvements to the device tree bindings aimed at making
validation better.
- PIO FIFO usage for the OMAP2 McSPI, improving performance.

The main change here is a fix for an issue where we were letting the
selector for windowed register ranges get out of sync with the hardware
during a cache sync plus associated KUnit tests. This was reported just
at the end of the release cycle and only in -next for a day prior to the
merge window so it seemed better to hold off for now, the bug had been
present for more than a decade so wasn't causing too many practical
problems hopefully. There's also a fix for error handling in the
debugfs output from Christope Jaillet.

GPIOLIB core:
- provide interfaces allowing users to retrieve, manage and query the
reference counted GPIO device instead of accessing the private gpio_chip
structure
- replace gpiochip_find() with gpio_device_find()
- remove unused acpi_get_and_request_gpiod()
- improve the ignore_interrupt functionality in GPIO ACPI
- correct notifier return codes in gpiolib-of
- unexport gpiod_set_transitory() as it's unused outside of core GPIO code
- while there are still external users accessing struct gpio_chip, let's
make gpiochip_get_desc() public so that they at least use the preferred
helper
- improve locking for lookup tables
- annotate struct linereq with __counted_by
- improve GPIOLIB docs
- add an OF quirk for LED trigger sources
Driver improvements:
- convert all GPIO drivers with .remove() callbacks to using the new
variant returning void instead of int
- stop accessing the GPIOLIB private structures in gpio-mockup,
i2c-mux-gpio, hte-tegra194, gpio-sim
- use the recommended pattern for autofree variables in gpio-sim
- add support for more models to gpio-loongson
- use a notifier chain to notify other blocks about interrupts in
gpio-eic-sprd instead of looking up GPIO devices on every interrupt
- convert gpio-pca953x and gpio-fx6408 to using the maple tree regmap
cache
- don't include GPIOLIB internal headers in drivers which don't need them
- move the ingenic NAND quirk into gpiolib-of
- add an ignore interrupt quirk for Peaq C1010
- drop static GPIO base from gpio-omap, gpio-f7188x

Merge tag 'gpio-updates-for-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"We don't have any new drivers. The loongson driver is getting extended
with support for new models. There's a big refactor of gpio-pca953x
and many small improvements to others.
The GPIO code in the kernel has acquired a lot of cruft over the years
as well as many abusers of the API across the kernel tree. This
release cycle we have started a major cleanup and improvement effort
that will most likely span several releases. We have started by
converting external users of struct gpio_chip to accessing the wrapper
around it - struct gpio_device. This is because the latter is
reference counted while the former is removed when the provider is
unbound. We also removed several instances of drivers accessing
private GPIOLIB structures and including the private header from
drivers/gpio/.
To that end you'll see several commits aimed at different subsystems
(acked by relevant maintainers) as well as two merges from the
x86/platform tree.
We'll then rework the locking in GPIOLIB which currently uses a big
spinlock for many different things and could use becoming more
fine-grained, especially as it doesn't even get the locking right.
We'll also use SRCU for protecting the gpio_chip pointer against
in-kernel hot-unplug crashes similar to what we saw triggered from
user-space and fixed with semaphores in gpiolib-cdev. The core GPIOLIB
is still vulnerable to these use-cases. I'm just mentioning the plans
here, this is not part of this PR.
You'll see some new instances of using __free(). We've added a
gpio_device_put cleanup helper similar to the put_device one
introduced by Peter Zijlstra and used it according to the preferred
pattern except where it didn't make sense.
GPIOLIB core:
- provide interfaces allowing users to retrieve, manage and query the
reference counted GPIO device instead of accessing the private
gpio_chip structure
- replace gpiochip_find() with gpio_device_find()
- remove unused acpi_get_and_request_gpiod()
- improve the ignore_interrupt functionality in GPIO ACPI
- correct notifier return codes in gpiolib-of
- unexport gpiod_set_transitory() as it's unused outside of core GPIO
code
- while there are still external users accessing struct gpio_chip,
let's make gpiochip_get_desc() public so that they at least use the
preferred helper
- improve locking for lookup tables
- annotate struct linereq with __counted_by
- improve GPIOLIB docs
- add an OF quirk for LED trigger sources
Driver improvements:
- convert all GPIO drivers with .remove() callbacks to using the new
variant returning void instead of int
- stop accessing the GPIOLIB private structures in gpio-mockup,
i2c-mux-gpio, hte-tegra194, gpio-sim
- use the recommended pattern for autofree variables in gpio-sim
- add support for more models to gpio-loongson
- use a notifier chain to notify other blocks about interrupts in
gpio-eic-sprd instead of looking up GPIO devices on every interrupt
- convert gpio-pca953x and gpio-fx6408 to using the maple tree regmap
cache
- don't include GPIOLIB internal headers in drivers which don't need
them
- move the ingenic NAND quirk into gpiolib-of
- add an ignore interrupt quirk for Peaq C1010
- drop static GPIO base from gpio-omap, gpio-f7188x
- use the preferred device_get_match_data() function in drivers that
still don't
- refactor gpio-pca953x: switch to using DEFINE_SIMPLE_DEV_PM_OPS(),
use cleanup helpers, use dev_err_probe() where it makes sense,
fully convert to using devres and some other minor tweaks
DT bindings:

LoongArch architecture changes for 6.7 (BPF CPU v4 support) depend on
the bpf changes to fix conflictions in selftests and work, so merge them
to create a base.
Sunil V L <sunilvl@ventanamicro.com> says:
This series is a set of patches which were originally part of RFC v1 series
[1] to add ACPI support in RISC-V interrupt controllers. Since these
patches are independent of the interrupt controllers, creating this new
series which helps to merge instead of waiting for big series.
This set of patches primarily adds support below ECR [2] which is approved
by the ASWG and adds below features.
- Get CBO block sizes from RHCT on ACPI based systems.
Additionally, the series contains a patch to improve acpi_os_ioremap().

The interrupt entries are expected to be in the .irqentry.text section.
For example, for kprobes to work properly, exception code cannot be
probed; this is ensured by blacklisting addresses in the .irqentry.text
section.

Actually it is a part of Conor's
commit aae538cd03 ("riscv: fix detection of toolchain
Zihintpause support").
It is looks like a merge issue. Samuel's
commit 0b1d60d6dd ("riscv: Fix build with
CONFIG_CC_OPTIMIZE_FOR_SIZE=y") do not base on Conor's commit and
revert to __riscv_zihintpause. So this patch can fix it.

Extensions prefixed with "Su" won't corrupt the workaround in many
cases. The only exception is when the first multi-letter extension in the
ISA string begins with "Su" and is not prefixed with an underscore.
For instance, following ISA string can confuse this QEMU workaround.
* "rv64imacsuclic" (RV64I + M + A + C + "Suclic")
However, this case is very unlikely because extensions prefixed by either
"Z", "Sm" or "Ss" will most likely precede first.
For instance, the "Suclic" extension (draft as of now) will be placed after
related "Smclic" and "Ssclic" extensions. It's also highly likely that
other unprivileged extensions like "Zba" will precede.
It's also possible to suppress the issue in the QEMU workaround with an
underscore. Following ISA string won't confuse the QEMU workaround.
* "rv64imac_suclic" (RV64I + M + A + C + delimited "Suclic")
This fix is to tell kernel developers the nature of this workaround
precisely. There are some "Su*" extensions to be ratified but don't worry
about this workaround too much.
This commit comes with other minor editorial fixes (for minor wording and
spacing issues, without changing the meaning).

The pt_level uses CONFIG_PGTABLE_LEVELS to display page table names.
But if page mode is downgraded from kernel cmdline or restricted by
the hardware in 64BIT, it will give a wrong name.
Like, using no4lvl for sv39, ptdump named the 1G-mapping as "PUD"
that should be "PGD":
0xffffffd840000000-0xffffffd900000000 0x00000000c0000000 3G PUD D A G . . W R V
So select "P4D/PUD" or "PGD" via pgtable_l5/4_enabled to correct it.

A few of the other page table level helpers are defined on rv32, but not
pgtable_l5_enabled. This adds the definition as a constant and converts
pgtable_l4_enabled to a constant as well.
