The HDMI PHY PLL can be used as an alternative dclk source to RK3588 SoC
CRU. It provides more accurate clock rates required by VOP2 to improve
existing support for display modes handling, which is known to be
problematic when dealing with non-integer refresh rates, among others.
It is worth noting this only works for HDMI 2.0 or below, e.g. cannot be
used to support HDMI 2.1 4K@120Hz mode.

When a new PHY is created via [devm_]phy_create(), the runtime PM for it
is not enabled unless the parent device (which creates the PHY) has its
own runtime PM already enabled.
Move the call to devm_pm_runtime_enable() before devm_phy_create() to
enable runtime PM at PHY core level.
With this change the ->power_on() and ->power_off() callbacks do not
require explicit runtime PM management anymore, since the PHY core
handles that via phy_pm_runtime_{get,put}_sync() when phy_power_on() and
phy_power_off() are invoked.
Hence drop the now unnecessary calls to pm_runtime_resume_and_get() and
pm_runtime_put() helpers.

The Torrent SERDES can support at most two different protocols (PHY types).
This only mandates that the device-tree sub-nodes used to represent the
configuration should describe links with at-most two different protocols.
The existing implementation however imposes an artificial constraint that
allows only two links (device-tree sub-nodes). As long as at-most two
protocols are chosen, using more than two links to describe them in an
alternating configuration is still a valid configuration of the Torrent
SERDES.
A 3-Link 2-Protocol configuration of the 4-Lane SERDES can be:
Lane 0 => Protocol 1 => Link 1
Lane 1 => Protocol 1 => Link 1
Lane 2 => Protocol 2 => Link 2
Lane 3 => Protocol 1 => Link 3
A 4-Link 2-Protocol configuration of the 4-Lane SERDES can be:
Lane 0 => Protocol 1 => Link 1
Lane 1 => Protocol 2 => Link 2

This simplifies the min_t() and max_t() macros by no longer making them
work in the context of a C constant expression.
That means that you can no longer use them for static initializers or
for array sizes in type definitions, but there were only a couple of
such uses, and all of them were converted (famous last words) to use
MIN_T/MAX_T instead.

Commit 3a7e02c040 ("minmax: avoid overly complicated constant
expressions in VM code") added the simpler MIN_T/MAX_T macros in order
to avoid some excessive expansion from the rather complicated regular
min/max macros.
The complexity of those macros stems from two issues:
(a) trying to use them in situations that require a C constant
expression (in static initializers and for array sizes)
(b) the type sanity checking
and MIN_T/MAX_T avoids both of these issues.
Now, in the whole (long) discussion about all this, it was pointed out
that the whole type sanity checking is entirely unnecessary for
min_t/max_t which get a fixed type that the comparison is done in.
But that still leaves min_t/max_t unnecessarily complicated due to
worries about the C constant expression case.
However, it turns out that there really aren't very many cases that use
min_t/max_t for this, and we can just force-convert those.
This does exactly that.
Which in turn will then allow for much simpler implementations of
min_t()/max_t(). All the usual "macros in all upper case will evaluate
the arguments multiple times" rules apply.
We should do all the same things for the regular min/max() vs MIN/MAX()
cases, but that has the added complexity of various drivers defining
their own local versions of MIN/MAX, so that needs another level of
fixes first.

After a recent change in clang to stop consuming all instances of '-S'
and '-c' [1], the stack protector scripts break due to the kernel's use
of -Werror=unused-command-line-argument to catch cases where flags are
not being properly consumed by the compiler driver:
$ echo | clang -o - -x c - -S -c -Werror=unused-command-line-argument
clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
This results in CONFIG_STACKPROTECTOR getting disabled because
CONFIG_CC_HAS_SANE_STACKPROTECTOR is no longer set.
'-c' and '-S' both instruct the compiler to stop at different stages of
the pipeline ('-S' after compiling, '-c' after assembling), so having
them present together in the same command makes little sense. In this
case, the test wants to stop before assembling because it is looking at
the textual assembly output of the compiler for either '%fs' or '%gs',
so remove '-c' from the list of arguments to resolve the error.
All versions of GCC continue to work after this change, along with
versions of clang that do or do not contain the change mentioned above.

Pull CXL updates from Dave Jiang:
"Core:
- A CXL maturity map has been added to the documentation to detail
the current state of CXL enabling.
It provides the status of the current state of various CXL features
to inform current and future contributors of where things are and
which areas need contribution.
- A notifier handler has been added in order for a newly created CXL
memory region to trigger the abstract distance metrics calculation.
This should bring parity for CXL memory to the same level vs
hotplugged DRAM for NUMA abstract distance calculation. The
abstract distance reflects relative performance used for memory
tiering handling.
- An addition for XOR math has been added to address the CXL DPA to
SPA translation.
CXL address translation did not support address interleave math
with XOR prior to this change.
Fixes:
- Fix to address race condition in the CXL memory hotplug notifier
- Add missing MODULE_DESCRIPTION() for CXL modules
- Fix incorrect vendor debug UUID define

Merge tag 'vfs-6.11-rc1.fixes.3' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs fixes from Christian Brauner:
"This contains two fixes for this merge window:
VFS:
- I noticed that it is possible for a privileged user to mount most
filesystems with a non-initial user namespace in sb->s_user_ns.
When fsopen() is called in a non-init namespace the caller's
namespace is recorded in fs_context->user_ns. If the returned file
descriptor is then passed to a process privileged in init_user_ns,
that process can call fsconfig(fd_fs, FSCONFIG_CMD_CREATE*),
creating a new superblock with sb->s_user_ns set to the namespace
of the process which called fsopen().
This is problematic as only filesystems that raise FS_USERNS_MOUNT
are known to be able to support a non-initial s_user_ns. Others may
suffer security issues, on-disk corruption or outright crash the
kernel. Prevent that by restricting such delegation to filesystems
that allow FS_USERNS_MOUNT.
Note, that this delegation requires a privileged process to
actually create the superblock so either the privileged process is
cooperaing or someone must have tricked a privileged process into
operating on a fscontext file descriptor whose origin it doesn't
know (a stupid idea).
The bug dates back to about 5 years afaict.
Misc:
- Fix hostfs parsing when the mount request comes in via the legacy
mount api.
In the legacy mount api hostfs allows to specify the host directory
mount without any key.
Restore that behavior"
* tag 'vfs-6.11-rc1.fixes.3' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
hostfs: fix the host directory parse when mounting.
fs: don't allow non-init s_user_ns for filesystems without FS_USERNS_MOUNT
The highlight is the establishment of a minimum version for the Rust
toolchain, including 'rustc' (and bundled tools) and 'bindgen'.
The initial minimum will be the pinned version we currently have, i.e.
we are just widening the allowed versions. That covers 3 stable Rust
releases: 1.78.0, 1.79.0, 1.80.0 (getting released tomorrow), plus beta,
plus nightly.
This should already be enough for kernel developers in distributions
that provide recent Rust compiler versions routinely, such as Arch
Linux, Debian Unstable (outside the freeze period), Fedora Linux,
Gentoo Linux (especially the testing channel), Nix (unstable) and
openSUSE Slowroll and Tumbleweed.
In addition, the kernel is now being built-tested by Rust's pre-merge
CI. That is, every change that is attempting to land into the Rust
compiler is tested against the kernel, and it is merged only if it
passes. Similarly, the bindgen tool has agreed to build the kernel in
their CI too.
Thus, with the pre-merge CI in place, both projects hope to avoid
unintentional changes to Rust that break the kernel. This means that,
in general, apart from intentional changes on their side (that we
will need to workaround conditionally on our side), the upcoming Rust
compiler versions should generally work.
In addition, the Rust project has proposed getting the kernel into
stable Rust (at least solving the main blockers) as one of its three
flagship goals for 2024H2 [1].
I would like to thank Niko, Sid, Emilio et al. for their help promoting
the collaboration between Rust and the kernel.
[1] https://rust-lang.github.io/rust-project-goals/2024h2/index.html#flagship-goals
Toolchain and infrastructure:
- Support several Rust toolchain versions.
- Support several bindgen versions.
- Remove 'cargo' requirement and simplify 'rusttest', thanks to 'alloc'
having been dropped last cycle.
- Provide proper error reporting for the 'rust-analyzer' target.
'kernel' crate:
- Add 'uaccess' module with a safe userspace pointers abstraction.
- Add 'page' module with a 'struct page' abstraction.
- Support more complex generics in workqueue's 'impl_has_work!' macro.
'macros' crate:
- Add 'firmware' field support to the 'module!' macro.
- Improve 'module!' macro documentation.
Documentation:
- Provide instructions on what packages should be installed to build
the kernel in some popular Linux distributions.
- Introduce the new kernel.org LLVM+Rust toolchains.
- Explain '#[no_std]'.
And a few other small bits.

"The highlight is the establishment of a minimum version for the Rust
toolchain, including 'rustc' (and bundled tools) and 'bindgen'.
The initial minimum will be the pinned version we currently have, i.e.
we are just widening the allowed versions. That covers three stable
Rust releases: 1.78.0, 1.79.0, 1.80.0 (getting released tomorrow),
plus beta, plus nightly.
This should already be enough for kernel developers in distributions
that provide recent Rust compiler versions routinely, such as Arch
Linux, Debian Unstable (outside the freeze period), Fedora Linux,
Gentoo Linux (especially the testing channel), Nix (unstable) and
openSUSE Slowroll and Tumbleweed.
In addition, the kernel is now being built-tested by Rust's pre-merge
CI. That is, every change that is attempting to land into the Rust
compiler is tested against the kernel, and it is merged only if it
passes. Similarly, the bindgen tool has agreed to build the kernel in
their CI too.
Thus, with the pre-merge CI in place, both projects hope to avoid
unintentional changes to Rust that break the kernel. This means that,
in general, apart from intentional changes on their side (that we will
need to workaround conditionally on our side), the upcoming Rust
compiler versions should generally work.
In addition, the Rust project has proposed getting the kernel into
stable Rust (at least solving the main blockers) as one of its three
flagship goals for 2024H2 [1].
I would like to thank Niko, Sid, Emilio et al. for their help
promoting the collaboration between Rust and the kernel.
Toolchain and infrastructure:
- Support several Rust toolchain versions.
- Support several bindgen versions.
- Remove 'cargo' requirement and simplify 'rusttest', thanks to
'alloc' having been dropped last cycle.
- Provide proper error reporting for the 'rust-analyzer' target.
'kernel' crate:
- Add 'uaccess' module with a safe userspace pointers abstraction.
- Add 'page' module with a 'struct page' abstraction.
- Support more complex generics in workqueue's 'impl_has_work!'
macro.
'macros' crate:
- Add 'firmware' field support to the 'module!' macro.
- Improve 'module!' macro documentation.
Documentation:
- Provide instructions on what packages should be installed to build
the kernel in some popular Linux distributions.
- Introduce the new kernel.org LLVM+Rust toolchains.
- Explain '#[no_std]'.
And a few other small bits"
