Add the MSM SDHCI compatible name to support both eMMC and SD card for
Lemans, which uses 'sa8775p' as the fallback SoC. Ensure the new
compatible string matches existing Lemans-compatible formats without
introducing a new naming convention.
The SDHCI controller on Lemans is based on MSM SDHCI v5 IP. Hence,
document the compatible with "qcom,sdhci-msm-v5" as the fallback.

https://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/samsung into devel
Samsung pinctrl drivers changes for v6.18
1. Add pin controller drivers for new Axis ARTPEC-8 SoC. The SoC shares
all main blocks, including the pin controller, with Samsung SoC, so
same drivers and bindings are used.
2. Drop remaining support for Samsung S3C2410 SoC pin controllers. The
actual SoC support was removed in January 2023, so this is just
remaining cleanup.

Merge series from Xianwei Zhao <xianwei.zhao@amlogic.com>:
This Flash Controller is derived by adding an SPI path to the original
raw NAND controller. This controller supports two modes: raw mode and
SPI mode. The raw mode has already been implemented in the community
(drivers/mtd/nand/raw/meson_nand.c).
This submission supports the SPI mode.
Add the drivers and bindings corresponding to the SPI Flash Controller.

Pull vmescape mitigation fixes from Dave Hansen:
"Mitigate vmscape issue with indirect branch predictor flushes.
vmscape is a vulnerability that essentially takes Spectre-v2 and
attacks host userspace from a guest. It particularly affects
hypervisors like QEMU.
Even if a hypervisor may not have any sensitive data like disk
encryption keys, guest-userspace may be able to attack the
guest-kernel using the hypervisor as a confused deputy.
There are many ways to mitigate vmscape using the existing Spectre-v2
defenses like IBRS variants or the IBPB flushes. This series focuses
solely on IBPB because it works universally across vendors and all
vulnerable processors. Further work doing vendor and model-specific
optimizations can build on top of this if needed / wanted.
Do the normal issue mitigation dance:
- Add the CPU bug boilerplate
- Add a list of vulnerable CPUs
- Use IBPB to flush the branch predictors after running guests"

In some cases it's reasonable to describe DP lanes and AUX signal lines
separately in the DT. One of the typical reasons is if the source of DP
signals can support either USB-C or DP connections. In such a case the
transmitter of DP signals have separate ports: one for SS lanes and
another one for SBU / AUX signals.
Instead of leaving AUX signals from the controller unconnected, add an
option to the DT schema to AUX signal lines separately from the main
link lanes.

With the introduction of the Icicle Kit using the production MPFS250T
device, it's necessary to distinguish it from the engineering sample
(-es) variant. Engineering samples cannot write to flash from the MSS,
as noted in the PolarFire SoC FPGA ES errata.
Add specific compatibles for the Icicle Kit with Production device
(MPFS250T) and Icicle Kit with Engineering Sample (MPFS250T_ES).
The icicle kit reference designs in the v2025.07 release include the
Mi-V IHC IP v2, used to send/receive data between clusters when
using Asymmetric Multiprocessing (AMP) mode.
In reference design releases prior to v2025.07, the MI-V IHC subsystem
was included as a proof of concept in the design prior to becoming an
IP available in the Libero catalog.
Among other improvements, the new Mi-V IHC IP v2 includes some
changes to the register map. For this reason, make use of a new
reference design compatible to denote that v2025.07 reference design
releases are not backwards compatible.

Digital LDO Regulators
The integrated PMU includes three digital LDO regulators: LDO_ARM, LDO_PU, and
LDO_SOC. These regulators provide power to the ARM_Core power domain, the
combined VPU, IPU and GPU power domain, and the rest of the SoC logic (except
always-ON SNVS domain)."
imx6dl.dtsi uses the correct names to describe these supplies:
arm-supply = <®_arm>;
pu-supply = <®_pu>;
soc-supply = <®_soc>;
'arm-supply' and 'soc-supply' are already documented, but 'pu-supply' is not.
Document the 'pu-supply' property and set it to deprecated.
This fixes the following dt-schema warning:
cpu@1 (arm,cortex-a9): Unevaluated properties are not allowed ('pu-supply' was unexpected)

The 5" and 7" Raspberry Pi 720x1280 Display 2 MCU is a bit more
complex than the original Display 1 ATTINY88 and the binding is
also a bit more demanding. Split the binding into separate file
and fill in required gpio-controller, #gpio-cells and #pwm-cells
which must be present for the V2 MCU. Include mention of the 5"
panel in the description of Display 2, as the 5" panel uses the
same MCU.

The ASpeed kcs-bmc nodes have a "clocks" property which isn't
documented. It looks like all the LPC child devices have the same clock
source and some of the drivers manage their clock. Perhaps it is the
parent device that should have the clock, but it's too late for that.

Implement locking in the hardware monitoring core for drivers using
the _with_info() API functions.
Most hardware monitoring drivers need to support locking to protect
against parallel accesses from userspace. With older API functions, such
locking had to be implemented in the driver code since sysfs attributes
were created by the driver. However, the _with_info() API creates sysfs
attributes in the hardware monitoring core. This makes it easy to move
the locking primitives into that code. This has the benefit of simplifying
driver code while at the same time reducing the risk of incomplete of bad
locking implementations in hardware monitoring drivers.
While this means that all accesses are forced to be synchronized, this
has little if any practical impact since accesses are expected to be low
frequency and are typically synchronized from userspace anyway since
only a single process is accessing the data. On top of that, many drivers
use regmap, which also has its own locking scheme and already serializes
accesses.
