Extend the existing Tegra186 GPIO controller device tree bindings with
support for the GPIO controller found on Tegra264. The number of pins
is slightly different, but the programming model remains the same.
Add a new header, include/dt-bindings/gpio/nvidia,tegra264-gpio.h,
that defines port IDs as well as the TEGRA264_MAIN_GPIO() helper,
both of which are used in conjunction to create a unique specifier
for each pin.
On Tegra, GPIO wake events are latched and routed via the PMC.
Document the standard DT property, wakeup-parent, which is a phandle to
the PMC interrupt controller that provides the parent wake interrupt
domain for the GPIO controller. If the property is absent the driver
falls back to a compatible-based lookup.

The s2io driver supports Exar (formerly Neterion and S2io) PCI-X 10
Gigabit Ethernet cards. Hardware supporting PCI-X has not been
manufactured in years. On x86, it was quickly replaced by PCIe. While
it stuck around longer on POWER hardware, the last POWER hardware to
support it was POWER7, which is not supported by ppc64le Linux
distributions. The last supported mainstream ppc64 Linux distribution
was RHEL 7; while it is still supported under ELS, ELS is only
available for x86 and IBM Z. It is possible to use many PCI-X cards in
standard PCI slots (which are still available on new motherboards), but
it does not make sense to do so for 10 Gigabit Ethernet because the
maximum bandwidth of standard PCI is only 1067 Mbps. It is therefore
highly unlikely that this driver is still being used. Remove the
driver, and move the former maintainer to the CREDITS file (restoring
credit for the vxge driver, which was removed in commit f05643a0f60b
("eth: remove neterion/vxge").

RISC-V Devicetrees for v6.20 (or v7.0)
Anlogic:
Minor change to the extension information, to add the "b" extension
that's a catch-all for 3 of the extensions already in the dts.
Starfive:
Append the jh7110 compatible to jh7110s devicetrees, as that will enable
OpenSBI etc to run without adding support for this minor variant. The
"s" device differs from the non "s" device only in
thermal limits and voltage/frequency characteristics.
Microchip:
Redo the mpfs clock setup yet again, to something approaching correct.
The original binding conjured up for the platform was wildly inaccurate,
and even with the original improvements, a bigger change to using
syscons was required to support several peripherals that also inhabit
the memory regions that the clocks lie in. The damage to the dts isn't
that bad in the end, and of course the whole thing has been done in a
backwards compatible manner, with the code changes being merged a cycle
or two ago in the kernel and like a year ago in U-Boot (the only other
user that I am aware of).
Generic:
Additions to extensions.yaml, mainly for things in the "rva23" profile
that appear for the first time on the Spacemit K3 SoC.

Address Space IDs allows the VDUSE framework to support devices able to
expose different virtqueues to different part of the drivers. For
example, to let QEMU handle the net device control virtqueue, so QEMU
always knows the state of the device like mac address or number of
queues enabled, while leaving the dataplane passthrough to the guest
intact. This enables live migration.
Expands the VDUSE documentation to explain how to use the new ioctls or
the new struct members of old ioctls.

Add scoped init guard definitions for common synchronization primitives
supported by context analysis.
The scoped init guards treat the context as active within initialization
scope of the underlying context lock, given initialization implies
exclusive access to the underlying object. This allows initialization of
guarded members without disabling context analysis, while documenting
initialization from subsequent usage.
The documentation is updated with the new recommendation. Where scoped
init guards are not provided or cannot be implemented (ww_mutex omitted
for lack of multi-arg guard initializers), the alternative is to just
disable context analysis where guarded members are initialized.

dt-bindings: Changes for v6.20-rc1
This series updates various DT bindings for Tegra architecture,
primarily focusing on schema validation fixes and new feature
documentation for Tegra234 and Tegra264 SoCs. Key changes include
converting Tegra20 NAND bindings to YAML, and updating memory, DMA, and
IOMMU definitions for Tegra264 (introducing CMDQV and DBB clock
support). Additionally, it resolves legacy warnings for Tegra30/132
display and VI interfaces.

Merge series from Chin-Ting Kuo <chin-ting_kuo@aspeedtech.com>:
This patch series improves handling of SPI controllers that are
shared by spi-mem devices and other SPI peripherals.
The primary goal of this series is to support non-spi-mem devices in
the ASPEED FMC/SPI controller driver. It also addresses an issue in
the spi-mem framework observed when different types of SPI devices
operate concurrently on the same controller, ensuring that spi-mem
operations are properly serialized.

Document the optional nxp,enable-termination-resistor property for the
i.MX LVDS display bridge.
This boolean property indicates that the built-in 100 Ohm termination
resistor on the LVDS output is enabled. It is controlled via the HS_EN
bit in the LVDS_CTRL register. Enabling the resistor can improve LVDS
signal quality and may prevent visual artifacts on some boards, but
increases the power consumption.

Merge series from "Anton D. Stavinskii" <stavinsky@gmail.com>:
This patch series adds basic audio support for Sophgo CV1800B,
as used on boards such as the Milk-V Duo.
The series introduces the I2S controller driver,
the DAC and ADC codec drivers, corresponding DT bindings,
and DTS updates to wire the components together.
The implementation is based on vendor documentation
and testing on real hardware. This series relies on
recent fixes in the DesignWare AXI DMA support;
in particular, correct operation depends on
the DMA changes discussed at:
https://lore.kernel.org/all/20251214224601.598358-1-inochiama@gmail.com/
The current driver implementation supports a fixed audio configuration
of 48 kHz sample rate and only I2S protocol which is used in codecs.
The series has been tested on the Milk-V Duo 256M board using
the Sophgo SG2002 SoC. The implementation is expected to also work on
Milk-V Duo and Milk-V Module boards based on the SG2000 SoC,
as the audio and DMA blocks are closely related.
Known hardware limitation:
On CV1800B / SG2002, the I2S2 output pins cannot be enabled via
pinctrl alone. Due to SoC design constraints, the output path becomes
functional only after additional vendor-specific register programming.
This series makes the limitation explicit and does not attempt
to work around it implicitly via pinctrl or undocumented behavior.

There are 4 TDM controllers on the SoC. Each controller can receive or
transmit data over DMA. The dma it self has 8 channels.
Each channel can be connected only to a specific i2s node. But each
of dma channel can have multiple purposes so in order to save dma
channels the configurations allows to use tx and rx, only rx, only tx
or none channels. I2S controller without channels can be useful in
configuration where I2S is used as clock source only and doesn't
produce any data.

Define CONFIG_ILLEGAL_POINTER_VALUE to the eye-catching non-zero value
of 0xdead000000000000, consistent with other architectures. Assert at
compile-time that the poison pointers that include/linux/poison.h
defines based on this illegal pointer are beyond the largest useful
virtual addresses. Also, assert at compile-time that the range of poison
pointers per include/linux/poison.h (currently a range of less than
0x10000 addresses) does not overlap with the range used for address
handles for s390's non-MIO PCI instructions.
This enables s390 to track the DMA mappings by the network stack's
page_pool that was introduced with [0]. Other functional changes are not
intended.
Other archictectures have introduced this for various other reasons with

Every architecture that supports hugetlb_cma command line parameter
reserves CMA areas for hugetlb during setup_arch().
This obfuscates the ordering of hugetlb CMA initialization with respect to
the rest initialization of the core MM.
Introduce arch_hugetlb_cma_order() callback to allow architectures report
the desired order-per-bit of CMA areas and provide a week implementation
of arch_hugetlb_cma_order() for architectures that don't support hugetlb
with CMA.
Use this callback in hugetlb_cma_reserve() instead if passing the order as
parameter and call hugetlb_cma_reserve() from mm_core_init_early() rather
than have it spread over architecture specific code.

Every architecture calls sparse_init() during setup_arch() although the
data structures created by sparse_init() are not used until the
initialization of the core MM.
Beside the code duplication, calling sparse_init() from architecture
specific code causes ordering differences of vmemmap and HVO
initialization on different architectures.
Move the call to sparse_init() from architecture specific code to
free_area_init() to ensure that vmemmap and HVO initialization order is
always the same.
