include listing
Stephen Rothwell reports htmldocs warning when merging iommu tree:
Documentation/driver-api/generic_pt.rst:32: WARNING: Literal block expected; none found. [docutils]
This is because of duplicate double colon code block markers: one after
generic_pt/fmt/iommu_amdv1.c and the one in its preceding paragraph. The
resulting htmldocs, however, only marks the include listing (after the
former) up as it should be.

Merge series from Alex Elder <elder@riscstar.com>:
This series adds support for the SpacemiT K1 SoC QSPI. This IP is
generally compatible with the Freescale QSPI driver, requiring three
minor changes to enable it to be supported. The changes are:
- Adding support for optional resets
- Having the clock *not* be disabled when changing its rate
- Allowing the size of storage blocks written to flash chips
to be set to something different from the AHB buffer size

Add support for standard tx-internal-delay-ps and rx-internal-delay-ps
properties on port nodes to allow fine-tuning of RGMII clock delays.
The GSWIP switch hardware supports delay values in 500 picosecond
increments from 0 to 3500 picoseconds, with a post-reset default of 2000
picoseconds for both TX and RX delays. The driver currently sets the
delay to 0 in case the PHY is setup to carry out the delay by the
corresponding interface modes ("rgmii-id", "rgmii-rxid", "rgmii-txid").
This corresponds to the driver changes that allow adjusting MII delays
using Device Tree properties instead of relying solely on the PHY
interface mode.

Add support for the maxlinear,rmii-refclk-out boolean property on port
nodes to configure the RMII reference clock to be an output rather than
an input.
This property is only applicable for ports in RMII mode and allows the
switch to provide the reference clock for RMII-connected PHYs instead
of requiring an external clock source.
This corresponds to the driver changes that read this Device Tree
property to configure the RMII clock direction.

Currently the i40e driver enforces its own internally calculated per-VF MAC
filter limit, derived from the number of allocated VFs and available
hardware resources. This limit is not configurable by the administrator,
which makes it difficult to control how many MAC addresses each VF may
use.
This patch adds support for the new generic devlink runtime parameter
"max_mac_per_vf" which provides administrators with a way to cap the
number of MAC addresses a VF can use:
- When the parameter is set to 0 (default), the driver continues to use
its internally calculated limit.
- When set to a non-zero value, the driver applies this value as a strict
cap for VFs, overriding the internal calculation.
Important notes:
- The configured value is a theoretical maximum. Hardware limits may
still prevent additional MAC addresses from being added, even if the
parameter allows it.
- Since MAC filters are a shared hardware resource across all VFs,
setting a high value may cause resource contention and starve other
VFs.
- This change gives administrators predictable and flexible control over
VF resource allocation, while still respecting hardware limitations.
- Previous discussion about this change:

Merge series from AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>:
This series adds support for three new MediaTek PMICs: MT6316, MT6363
and MT6373 and their variants - used in board designs featuring the
MediaTek MT8196 Chromebook SoC, or the MT6991 Dimensity 9400 Smartphone
SoC.
In particular, MT6316 is a regulator, but the MT6363 and MT6373 PMICs
are multi-function devices, as they have and expose multiple sub-devices;
moreover, some of those also contain an interrupt controller, managing
internal IPs interrupts: for those, a chained interrupt handler is
registered, which parent is the SPMI controller itself.
This series adds support for all of the MT6316 regulator variants and
for MT6363, MT6373 SPMI PMICs and their interrupt controller.

Avoid case-sensitive sorting when listing Documentation targets in make help.
Previously, targets like PCI and RCU appeared ahead of others due to uppercase
names.
Normalize casing during _SPHINXDIRS generation to ensure consistent and
intuitive ordering.

Commit 0122938a7ab4 ("rtla: Always set all tracer options") changed the
behavior of RTLA to always set all osnoise and timerlat tracer options
to default values taken from the tracers whenever an RTLA measurement
is started. The change was done to make RTLA results consistent on
subsequent runs of the same command.
Include the default values for tracer options also in documentation
where appropriate.

The timerlat tracer documentation mentions that threads are created with
real-time priority, but does not mention which priority and scheduling
class is used.
Add the information so that users do not have to look it up in
trace_osnoise.c.

The RTLA option -C/--cgroup is used to set a cgroup for workload
threads. This is either a specific cgroup, if passed an argument, or
rtla's cgroup, if no argument is given.
Expand the documentation of the -C option to also include the
information about the cgroup settings when the option is not specified.

RTLA allows the priority of workload threads to be set using the -P
option. This is covered in docs, but the default state for RTLA's own
user workload (implemented in timerlat_u.c) is not mentioned.
Add mention of the default user workload priority as well as a reference
to osnoise and timerlat tracers for kernel workload priority.
