Add the TS233 compatible and affiliated driver data to qnap-mcu.
The TS233 is mostly similar to the TS433, except not having any of the
PCIe components, so there are only 2 drives.
The fan pwm-limits from the vendor-configuration also are the same
as for the ts433 variant.

In adp5585_reset_ev_parse(), when parsing the
adi,reset-pulse-width-us property, we were returning in case it was
found and valid. No point in doing that as we'll be returning anyways
after the exiting the property scope. And it could actually lead to bugs
if new properties happen to added after this one.

The Allwinner A523 SoC family has a second Ethernet controller, called
the GMAC200 in the BSP and T527 datasheet, and referred to as GMAC1 for
numbering. This controller, according to BSP sources, is fully
compatible with a slightly newer version of the Synopsys DWMAC core.
The glue layer around the controller is the same as found around older
DWMAC cores on Allwinner SoCs. The only slight difference is that since
this is the second controller on the SoC, the register for the clock
delay controls is at a different offset. Last, the integration includes
a dedicated clock gate for the memory bus and the whole thing is put in
a separately controllable power domain.
Add a new driver for this hardware supporting the integration layer.

Ensure that imported buffers are properly mapped and unmapped in
the same way as regular buffers to properly handle buffers during
device's bind and unbind operations to prevent resource leaks and
inconsistent buffer states.
Imported buffers are now dma_mapped before submission and
dma_unmapped in ivpu_bo_unbind(), guaranteeing they are unmapped
when the device is unbound.
Add also imported buffers to vdev->bo_list for consistent unmapping
on device unbind. The bo->ctx_id is set in open() so imported
buffers have a valid context ID.
Debug logs have been updated to match the new code structure.
The function ivpu_bo_pin() has been renamed to ivpu_bo_bind()
to better reflect its purpose, and unbind tests have been refactored
for improved coverage and clarity.

According to the eDP specification (VESA Embedded DisplayPort Standard
v1.4b, Section 3.3.10.2), if the value of DP_EDP_PWMGEN_BIT_COUNT is
less than DP_EDP_PWMGEN_BIT_COUNT_CAP_MIN, the sink is required to use
the MIN value as the effective PWM bit count.
This commit updates the logic to clamp the reported
DP_EDP_PWMGEN_BIT_COUNT to the range defined by _CAP_MIN and _CAP_MAX.
As part of this change, the behavior is modified such that reading both
_CAP_MIN and _CAP_MAX registers is now required to succeed, otherwise
bl->max value could end up being not set although
drm_edp_backlight_probe_max() returned success.
This ensures correct handling of eDP panels that report a zero PWM
bit count but still provide valid non-zero MIN and MAX capability
values. Without this clamping, brightness values may be interpreted
incorrectly, leading to a dim or non-functional backlight.
For example, the Samsung ATNA40YK20 OLED panel used in the Lenovo
ThinkPad T14s Gen6 (Snapdragon) reports a PWM bit count of 0, but
supports AUX backlight control and declares a valid 11-bit range.
Clamping ensures brightness scaling works as intended on such panels.

The vblank timer simulates a vblank interrupt for hardware without
support. Rate-limits the display update frequency.
DRM drivers for hardware without vblank support apply display updates
ASAP. A vblank event informs DRM clients of the completed update.
Userspace compositors immediately schedule the next update, which
creates significant load on virtualization outputs. Display updates
are usually fast on virtualization outputs, as their framebuffers are
in regular system memory and there's no hardware vblank interrupt to
throttle the update rate.
The vblank timer is a HR timer that signals the vblank in software.
It limits the update frequency of a DRM driver similar to a hardware
vblank interrupt. The timer is not synchronized to the actual vblank
interval of the display.
The code has been adopted from vkms, which added the funtionality
in commit 3a0709928b17 ("drm/vkms: Add vblank events simulated by
hrtimers").
The new implementation is part of the existing vblank support,
which sets up the timer automatically. Drivers only have to start
and cancel the vblank timer as part of enabling and disabling the
CRTC. The new vblank helper library provides callbacks for struct
drm_crtc_funcs.
The standard way for handling vblank is to call drm_crtc_handle_vblank().
Drivers that require additional processing, such as vkms, can init
handle_vblank_timeout in struct drm_crtc_helper_funcs to refer to
their timeout handler.
There's a possible deadlock between drm_crtc_handle_vblank() and
hrtimer_cancel(). [1] The implementation avoids to call hrtimer_cancel()
directly and instead signals to the timer function to not restart
itself.
v4:
- fix possible race condition between timeout and atomic commit (Michael)
v3:
- avoid deadlock when cancelling timer (Ville, Lyude)
v2:
- implement vblank timer entirely in vblank helpers
- downgrade overrun warning to debug
- fix docs

Pull rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Derive 'Zeroable' for all structs and unions generated by 'bindgen'
where possible and corresponding cleanups. To do so, add the
'pin-init' crate as a dependency to 'bindings' and 'uapi'.
It also includes its first use in the 'cpufreq' module, with more
to come in the next cycle.
- Add warning to the 'rustdoc' target to detect broken 'srctree/'
links and fix existing cases.
- Remove support for unused (since v6.16) host '#[test]'s,
simplifying the 'rusttest' target. Tests should generally run
within KUnit.
'kernel' crate:
- Add 'ptr' module with a new 'Alignment' type, which is always a
power of two and is used to validate that a given value is a valid
alignment and to perform masking and alignment operations:
// Checked at build time.
assert_eq!(Alignment::new::<16>().as_usize(), 16);
// Checked at runtime.
assert_eq!(Alignment::new_checked(15), None);
assert_eq!(Alignment::of::<u8>().log2(), 0);
assert_eq!(0x25u8.align_down(Alignment::new::<0x10>()), 0x20);
assert_eq!(0x5u8.align_up(Alignment::new::<0x10>()), Some(0x10));
assert_eq!(u8::MAX.align_up(Alignment::new::<0x10>()), None);
It also includes its first use in Nova.
- Add 'core::mem::{align,size}_of{,_val}' to the prelude, matching
Rust 1.80.0.
- Keep going with the steps on our migration to the standard library
'core::ffi::CStr' type (use 'kernel::{fmt, prelude::fmt!}' and use
upstream method names).
- 'error' module: improve 'Error::from_errno' and 'to_result'
documentation, including examples/tests.
- 'sync' module: extend 'aref' submodule documentation now that it
exists, and more updates to complete the ongoing move of 'ARef' and
'AlwaysRefCounted' to 'sync::aref'.
- 'list' module: add an example/test for 'ListLinksSelfPtr' usage.
- 'alloc' module:
- Implement 'Box::pin_slice()', which constructs a pinned slice of
elements.
- Provide information about the minimum alignment guarantees of
'Kmalloc', 'Vmalloc' and 'KVmalloc'.
- Take minimum alignment guarantees of allocators for
'ForeignOwnable' into account.
- Remove the 'allocator_test' (including 'Cmalloc').
- Add doctest for 'Vec::as_slice()'.
- Constify various methods.
- 'time' module:
- Add methods on 'HrTimer' that can only be called with exclusive
access to an unarmed timer, or from timer callback context.
- Add arithmetic operations to 'Instant' and 'Delta'.
- Add a few convenience and access methods to 'HrTimer' and
'Instant'.
'macros' crate:
- Reduce collections in 'quote!' macro.
And a few other cleanups and improvements"

When a PF enters switchdev mode, its netdevice becomes the uplink
representor but remains in its current network namespace. All other
representors (VFs, SFs) are created in the netns of the devlink
instance.
If the PF's netns has been moved and differs from the devlink's netns,
enabling switchdev mode would create a state where the OVS control
plane (ovs-vsctl) cannot manage the switch because the PF uplink
representor and the other representors are split across different
namespaces.
To prevent this inconsistent configuration, block the request to enter
switchdev mode if the PF netdevice's netns does not match the netns of
its devlink instance.
As part of this change, the PF's netns is first marked as immutable.
This prevents race conditions where the netns could be changed after
the check is performed but before the mode transition is complete, and
it aligns the PF's behavior with that of the final uplink representor.

The existing solution of complex matchers splits the match parameters
across two, and exactly two, matchers. For some rather extreme cases
(e.g. IPv6-in-IPv6 tunnels), even two matchers are not enough.
Generalize complex matchers to up to 4 submatchers, and allow easy
extension to more if needed. This resulted in rewriting a large part
of the high-level complex matchers logic, but the original concepts
were rock solid and still hold.
Key characteristics of the new implementation:
* Rework complex matchers to include multiple submatchers. All
submatchers but the first are isolated, in keeping with the existing
paradigm of handing off to specialized matchers that are not otherwise
reachable by regular rules.
* Similarly, rework complex rules to allow splitting them into more than
two simple rules. Rules continue to be refcounted to allow for
multiple complex rules matching on identical parts of the match
params.
* Rely on the match tag, as opposed to the entire match_param, to hash
subrules. This results in lower memory usage.
* Prefer to split the original user-supplied match parameters rather
than the internal field descriptors. This avoids the awkward
transition back and forth between the two formats.
* Allow splitting multi-dword fields across matchers. The only
restrictions that the new implementation impose are: a) any fragment
of an IP address must be accompanied by a match on the IP version; and
b) a single lower dword of an IPv6 address cannot be present in a
submatcher as it would be interpreted as an IPv4 address.
* Employ a greedy algorithm to split the match params, as opposed to
complete search. The results are not optimal, but the algorithm is now
linear compared to exponential. Consequently, we see complex matcher
creation time drops two orders of magnitude in our tests.

At present VMBus driver is hinged off of CONFIG_HYPERV which entails
lot of builtin code and encompasses too much. It's not always clear
what depends on builtin hv code and what depends on VMBus. Setting
CONFIG_HYPERV as a module and fudging the Makefile to switch to builtin
adds even more confusion. VMBus is an independent module and should have
its own config option. Also, there are scenarios like baremetal dom0/root
where support is built in with CONFIG_HYPERV but without VMBus. Lastly,
there are more features coming down that use CONFIG_HYPERV and add more
dependencies on it.
So, create a fine grained HYPERV_VMBUS option and update Kconfigs for
dependency on VMBus.

Pull irq chip driver updates from Thomas Gleixner:
- Use the startup/shutdown callbacks for the PCI/MSI per device
interrupt domains.
This allows us to initialize the RISCV PLIC interrupt hierarchy
correctly and provides a mechanism to decouple the masking and
unmasking during run-time from the expensive PCI mask and unmask when
the underlying MSI provider implementation allows the interrupt to be
masked.
- Initialize the RISCV PLIC MSI interrupt hierarchy correctly so that
the affinity assignment works correctly by switching it over to the
startup/shutdown scheme
- Allow MSI providers to opt out from masking a PCI/MSI interrupt at
the PCI device during operation when the provider can mask the
interrupt at the underlying interrupt chip. This reduces the overhead
in scenarios where disable_irq()/enable_irq() is utilized frequently
by a driver.
The PCI/MSI device level [un]masking is only required on startup and
shutdown in this case.
- Remove the conditional mask/unmask logic in the PCI/MSI layer as this
is now handled unconditionally.
- Replace the hardcoded interrupt routing in the Loongson EIOINTC
interrupt driver to respect the firmware settings and spread them out
to different CPU interrupt inputs so that the demultiplexing handler
only needs to read only a single 64-bit status register instead of
four, which significantly reduces the overhead in VMs as the status
register access causes a VM exit.
- Add support for the new AST2700 SCU interrupt controllers
- Use the legacy interrupt domain setup for the Loongson PCH-LPC
interrupt controller, which resembles the x86 legacy PIC setup and
has the same hardcoded legacy requirements.

Move away from the legacy MSI domain setup, switch to use
msi_create_parent_irq_domain().
While doing the conversion, I noticed that hv_irq_compose_msi_msg() is
doing more than it is supposed to (composing message content). The
interrupt allocation bits should be moved into hv_msi_domain_alloc().
However, I have no hardware to test this change, therefore I leave a TODO
note.
