Document the Synaptics TDDI (Touch/Display Integration) panel hardware.
Along with the MIPI-DSI panel, these devices also have an in-built LED
backlight device and a touchscreen, all packed together in a single chip.
Also, add compatibles for supported panels - TD4101 and TD4300. Both
have the '-panel' suffix so as to remove any ambiguity between the panel
and touchscreen chips.

connector status to:

If the device is enabled, updating the status hot-plug or unplugs the

Rework the current allOf: section such that all handling of
clocks/clock-names properties happens first, and all handling
of power-domains/power-domain-names happens second.
This allows the allOf section to limit various GPU models to
matching clocks count in the first half, and apply the same
for power-domains count in the second half, without conflating
the two limits together.
This makes addition of GPU models with different clocks and
power-domains count easier. No functional change intended.

Aside from the main CMA region, it can be useful to allow userspace to
allocate from the other CMA reserved regions.
Indeed, those regions can have specific properties that can be useful to
a specific us-case.
For example, one of them platform I've been with has ECC enabled on the
entire memory but for a specific region. Using that region to allocate
framebuffers can be particular beneficial because enabling the ECC has a
performance and memory footprint cost.
Thus, exposing these regions as heaps user-space can allocate from and
import wherever needed allows to cover that use-case.
For now, only shared-dma-pools regions with the reusable property (ie,
backed by CMA) are supported, but eventually we'll want to support other
DMA pools types.
Since we collected all the CMA regions created during boot, we can
simply iterate over all of them to create the heaps.
This has a weird interaction with the recent work on the CMA name, in
particular the backward compatibility code created by commit
854acbe75f ("dma-buf: heaps: Give default CMA heap a fixed name").
Indeed, the old name was either 'reserved', or the name of the
reserved-memory region device tree node if the linux,cma-default
property was set.
In both these cases, we have now collected this region during boot, and
we're using the same name. So we're now largely redundant with the
code to handle backward compatibility code, and we can thus remove it
and the associated Kconfig option.

Since we're going to introduce multiple instances of the CMA heap
driver, there's no single CMA heap anymore.
Let's use the heap name instead to differentiate between all the heaps
available in the system.
While we're at it, let's also rework the backward compatibility part to
make it easier to amend later on.

`rustfmt`, by default, formats imports in a way that is prone to conflicts
while merging and rebasing, since in some cases it condenses several
items into the same line.
For instance, Linus mentioned [1] that the following case:
use crate::{
fmt,
page::AsPageIter,
};
is compressed by `rustfmt` into:
use crate::{fmt, page::AsPageIter};
which is undesirable.
Similarly, `rustfmt` may put several items in the same line even if the
braces span already multiple lines, e.g.:
use kernel::{
acpi, c_str,
device::{property, Core},
of, platform,
};
The options that control the formatting behavior around imports are
generally unstable, and `rustfmt` releases do not allow to use nightly
features, unlike the compiler and other Rust tooling [2].
For the moment, we can introduce a workaround to prevent `rustfmt`
from compressing the example above -- the "trailing empty comment":
use crate::{
fmt,
page::AsPageIter, //
};
which is reminiscent of the trailing comma behavior in other formatters.
We already used empty comments for formatting purposes in the past,
e.g. in commit b9b701fce4 ("rust: clarify the language unstable features
in use").
In addition, `rustfmt` actually reformats with a vertical layout (i.e. it
does not put two items in the same line) when seeing such a comment,
i.e. it doesn't just preserve the formatting, which is good in the sense
that we can use it to easily reformat some imports, since it matches
the style we generally want to have.
A Git merge driver would help (suggested by Gary and Wedson), though
maintainers would need to set it up, the diffs would still be larger
and the formatting rules for imports would remain hard to predict.
Thus document the style that we will follow in the coding guidelines
by introducing a new section and explain how the trailing empty comment
works there too.
We discussed the issue with upstream Rust in our usual Rust <-> Rust
for Linux meeting [3], and there have also been a few other discussions
in parallel in issues [4][5] and Zulip [6]. We will see what happens,
but upstream Rust has already created a subteam of `rustfmt` to try
to overcome the bandwidth issue [7], which is a good signal, and some
organization work has already started (e.g. tracking issues). We will
continue our discussions with them about it.

====================
pull-request: can 2025-10-14
The first 2 paches are by Celeste Liu and target the gS_usb driver.
The first patch remove the limitation to 3 CAN interface per USB
device. The second patch adds the missing population of
net_device->dev_port.
The next 4 patches are by me and fix the m_can driver. They add a
missing pm_runtime_disable(), fix the CAN state transition back to
Error Active and fix the state after ifup and suspend/resume.
Another patch by me targets the m_can driver, too and replaces Dong
Aisheng's old email address.
The next 2 patches are by Vincent Mailhol and update the CAN
networking Documentation.
Tetsuo Handa contributes the last patch that add missing cleanup calls
in the NETDEV_UNREGISTER notification handler.

* Fix regression caused by removing CONFIG_EXT3_FS when testing some
very old defconfigs
* Avoid a BUG_ON when opening a file on a maliciously corrupted file system
* Avoid mm warnings when freeing a very large orphan file metadata
* Avoid a theoretical races between metadata wrtteback and checkpoints.
(It's very hard to hit in practice, since the race requires that the
writeback take a very long time.)

system
- Avoid mm warnings when freeing a very large orphan file metadata
- Avoid a theoretical races between metadata writeback and checkpoints

* tag 'ext4_for_linus-6.18-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4:
Use CONFIG_EXT4_FS instead of CONFIG_EXT3_FS in all of the defconfigs
ext4: free orphan info with kvfree
ext4: detect invalid INLINE_DATA + EXTENTS flag combination
ext4, doc: fix and improve directory hash tree description
ext4: wait for ongoing I/O to complete before freeing blocks
jbd2: ensure that all ongoing I/O complete before freeing blocks
The CAN-FD section of can.rst still states that there is a 1:1 mapping
between the Classical CAN DLC and its length. This is only true for
the DLC values up to 8. Beyond that point, the length remains at 8.
For reference, the mapping between the CAN DLC and the length is given
in below table [1]:
DLC value CBFF and CEFF FBFF and FEFF
[decimal] [byte] [byte]
----------------------------------------------
0 0 0
1 1 1
2 2 2
3 3 3
4 4 4
5 5 5
6 6 6
7 7 7
8 8 8
9 8 12
10 8 16
11 8 20
12 8 24
13 8 32
14 8 48
15 8 64
Remove the erroneous statement. Instead just state that the length of
a Classical CAN frame ranges from 0 to 8.

GICv5 hosts optionally include FEAT_GCIE_LEGACY, which allows them to
execute GICv3-based VMs on GICv5 hardware. Update the GICv3
documentation to reflect this now that GICv3 guests are supports on
compatible GICv5 hosts.
