The QUICC Engine provides interrupts for a few I/O ports. This is
handled via a separate interrupt ID and managed via a triplet of
dedicated registers hosted by the SoC.
Implement an interrupt driver for it so that those IRQs can then
be linked to the related GPIOs.

Add a new config IOMMU_DEBUG_PAGEALLOC, which registers new data to
page_ext.
This config will be used by the IOMMU API to track pages mapped in
the IOMMU to catch drivers trying to free kernel memory that they
still map in their domains, causing all types of memory corruption.
This behaviour is disabled by default and can be enabled using
kernel cmdline iommu.debug_pagealloc.

Legacy resctrl features are enumerated by X86_FEATURE_* flags. These may be
overridden by quirks to disable features in the case of errata. Users can use
kernel command line options to either disable a feature, or to force enable
a feature that was disabled by a quirk.
A different approach is needed for hardware features that do not have an
X86_FEATURE_* flag.
Update parsing of the "rdt=" boot parameter to call the telemetry driver
directly to handle new "perf" and "energy" options that controls activation of
telemetry monitoring of the named type. By itself a "perf" or "energy" option
controls the forced enabling or disabling (with ! prefix) of all event groups
of the named type. A ":guid" suffix allows for fine grained control per event
group.

The EM YNL specification used many acronyms, including ‘em’, ‘pd’,
‘ps’, etc. While the acronyms are short and convenient, they could be
confusing. So, let’s spell them out to be more specific. The following
changes were made in the spec. Note that the protocol name cannot exceed
GENL_NAMSIZ (16).
em -> dev-energymodel
pds -> perf-domains
pd -> perf-domain
pd-id -> perf-domain-id
pd-table -> perf-table
ps -> perf-state
get-pds -> get-perf-domains
get-pd-table -> get-perf-table
pd-created -> perf-domain-created
pd-updated -> perf-domain-updated
pd-deleted -> perf-domain-deleted
In addition. doc strings were added to the spec. based on the comments in
energy_model.h. Two flag attributes (perf-state-flags and
perf-domain-flags) were added for easily interpreting the bit flags.
Finally, the autogenerated files and em_netlink.c were updated accordingly
to reflect the name changes.

Add an attribute of "no-hpd" for the Rockchip dw-hdmi-qp controller.
This is used to describe implementations where the HPD pin is not
connected or used for other purposes, such as in the RK3588S based
Gameforce Ace which repurposed the GPIO for an additional face
button.
The "no-hpd" option was chosen to be consistent with other devices
which already define this parameter for broken or missing hpd
functionality.

Pull vfs fixes from Christian Brauner:
- Remove incorrect __user annotation from struct xattr_args::value
- Documentation fix: Add missing kernel-doc description for the @isnew
parameter in ilookup5_nowait() to silence Sphinx warnings
- Documentation fix: Fix kernel-doc comment for __start_dirop() - the
function name in the comment was wrong and the @state parameter was
undocumented
- Replace dynamic folio_batch allocation with stack allocation in
iomap_zero_range(). The dynamic allocation was problematic for
ext4-on-iomap work (didn't handle allocation failure properly) and
triggered lockdep complaints. Uses a flag instead to control batch
usage
- Re-add #ifdef guards around PIDFD_GET_<ns-type>_NAMESPACE ioctls.
When a namespace type is disabled, ns->ops is NULL, causes crashes
during inode eviction when closing the fd. The ifdefs were removed in
a recent simplification but are still needed
- Fixe a race where a folio could be unlocked before the trailing zeros
(for EOF within the page) were written
- Split out a dedicated lease_dispose_list() helper since lease code
paths always know they're disposing of leases. Removes unnecessary
runtime flag checks and prepares for upcoming lease_manager
enhancements
- Fix userland delegation requests succeeding despite conflicting
opens. Previously, FL_LAYOUT and FL_DELEG leases bypassed conflict
checks (a hack for nfsd). Adds new ->lm_open_conflict() lease_manager
operation so userland delegations get proper conflict checking while
nfsd can continue its own conflict handling
- Fix LOOKUP_CACHED path lookups incorrectly falling through to the
slow path. After legitimize_links() calls were conditionally elided,
the routine would always fail with LOOKUP_CACHED regardless of
whether there were any links. Now the flag is checked at the two
callsites before calling legitimize_links()
- Fix bug in media fd allocation in media_request_alloc()
- Fix mismatched API calls in ecryptfs_mknod(): was calling
end_removing() instead of end_creating() after
ecryptfs_start_creating_dentry()
- Fix dentry reference count leak in ecryptfs_mkdir(): a dget() of the
lower parent dir was added but never dput()'d, causing BUG during
lower filesystem unmount due to the still-in-use dentry

Various boards that use the rt5640 audio codec define a 'port' child
node under the codec node to describe the interface between it and the
SoC that it is connected to. The binding document for the rt5640 codec
does not define the 'port' child node and so this is generating warnings
when running the DTB checks for these boards. Add the 'port' node to the
binding document for the rt5640 codec to fix this.

The device-tree property 'realtek,jack-detect-source' currently only
permits values from 0-6. However, commit 2b9c8d2b3c89 ("ASoC: rt5640:
Add the HDA header support") updated the Realtek rt5640 to support
setting the 'realtek,jack-detect-source' to 7 to support the HDA header.
The Tegra234 platforms currently set 'realtek,jack-detect-source' to 7
for the HDA header and this is causing a warning when building
device-tree.
audio-codec@1c (realtek,rt5640): realtek,jack-detect-source:
7 is not one of [0, 1, 2, 3, 4, 5, 6]
Given that the driver already supports this settings, update the binding
document for the rt5640 device to add the HDA header as a valid
configuration for the 'realtek,jack-detect-source' property.

Introduce sysfs interfaces for 3 new Data Streaming Accelerator (DSA)
capability registers (dsacap0-2) to enable userspace awareness of hardware
features in DSA version 3 and later devices.
Userspace components (e.g. configure libraries, workload Apps) require this
information to:
1. Select optimal data transfer strategies based on SGL capabilities
2. Enable hardware-specific optimizations for floating-point operations
3. Configure memory operations with proper numerical handling
4. Verify compute operation compatibility before submitting jobs
The output format is <dsacap2>,<dsacap1>,<dsacap0>, where each DSA
capability value is a 64-bit hexadecimal number, separated by commas.
The ordering follows the DSA 3.0 specification layout:
Offset: 0x190 0x188 0x180
Reg: dsacap2 dsacap1 dsacap0
Example:
cat /sys/bus/dsa/devices/dsa0/dsacaps
000000000000f18d,0014000e000007aa,00fa01ff01ff03ff
According to the DSA 3.0 specification, there are 15 fields defined for
the three dsacap registers. However, there's no need to define all
register structures unless a use case requires them. At this point,
support for the Scatter-Gather List (SGL) located in dsacap0 is necessary,
so only dsacap0 is defined accordingly.
For reference, the DSA 3.0 specification is available at:

There are multiple design tradeoffs and considerations in how the
PCA953x driver detects the source(s) of an interrupt. This driver
supports PCAL variants with input latching, a feature that is
constrained by the fact that the interrupt status and input port
registers cannot be read atomically. These limits and the design
decisions deserve an in-depth explanation.
Update the documentation to clarify these hardware limits and describe
how the driver determines pending interrupts, and how it makes use of
the PCAL input latching.

The DVFSRC hardware has a clock on all platforms.
Instead or proliferating the culture of omitting clock descriptions in
the clock controller drivers or marking them critical instead of
declaring these types of relationships, add this one to the binding.
Any device that wishes to use this binding should figure out their
incomplete or incorrect clock situation first before piling more
features on top.

On processors starting from Panther Lake, additional workload type hints
are provided.
The hardware analyzes workload residencies over an extended period to
determine whether the workload classification tends toward idle/battery
life states or sustained/performance states. Based on this long-term
analysis, it classifies:
Power Classification: If the workload exhibits more idle or battery
life residencies, it is classified as "power". This is indicated by
setting bit 4 of the current workload type.
Performance Classification: If the workload exhibits more sustained
or performance residencies, it is classified as "performance". This
is indicated by clearing bit 4 of the current workload type.
This approach enables applications to ignore short-term workload
fluctuations and instead respond to longer-term power vs. performance
trends. Hints of this type are called slow workload hints.
To get notifications for slow workload hints, bit 22 in the thermal
mailbox can be used for configuring workload interrupts. It is possible
to exclusively enable slow workload hints or enable them in addition to
the current workload hints.
To enable slow workload hints, a new sysfs attribute is added to the
existing workload hint attributes:
workload_slow_hint_enable (RW): Write 1 to enable, 0 to disable.
Reading this attribute shows the current state.
This attribute is not present on any previous generation of processors.

Qualcomm GX(graphics) is a clock controller which has PLLs, clocks and
Power domains (GDSC), but the requirement from the SW driver is to use
the GDSC power domain from the clock controller to recover the GPU
firmware in case of any failure/hangs. The rest of the resources of the
clock controller are being used by the firmware of GPU. This module
exposes the GDSC power domains which helps the recovery of Graphics
subsystem.
Add bindings documentation for the Kaanapali Graphics Clock and Graphics
power domain Controller for Kaanapali SoC.
