Pull MSI updates from Thomas Gleixner:
"Updates for the MSI subsystem (core code and PCI):
- Switch the MSI descriptor locking to lock guards
- Replace a broken and naive implementation of PCI/MSI-X control word
updates in the PCI/TPH driver with a properly serialized variant in
the PCI/MSI core code.
- Remove the MSI descriptor abuse in the SCCI/UFS/QCOM driver by
replacing the direct access to the MSI descriptors with the proper
API function calls. People will never understand that APIs exist
for a reason...
- Provide core infrastructre for the upcoming PCI endpoint library
extensions. Currently limited to ARM GICv3+, but in theory
extensible to other architectures.
- Provide a MSI domain::teardown() callback, which allows drivers to
undo the effects of the prepare() callback.
- Move the MSI domain::prepare() callback invocation to domain
creation time to avoid redundant (and in case of ARM/GIC-V3-ITS
confusing) invocations on every allocation.
In combination with the new teardown callback this removes some
ugly hacks in the GIC-V3-ITS driver, which pretended to work around
the short comings of the core code so far. With this update the
code is correct by design and implementation.
- Make the irqchip MSI library globally available, provide a MSI
parent domain creation helper and convert a bunch of (PCI/)MSI
drivers over to the modern MSI parent mechanism. This is the first
step to get rid of at least one incarnation of the three PCI/MSI
management schemes.
- The usual small cleanups and improvements"

- A new driver fot the interrupt controller in the EcoNet EN751221
MIPS SoC.
- Extend the SG2042-MSI driver to support the new SG2044 SoC

irq_domain_add_*() interfaces are going away as being obsolete now.
Switch to the preferred irq_domain_create_*() ones. Those differ in the
node parameter: They take more generic struct fwnode_handle instead of
struct device_node. Therefore, of_fwnode_handle() is added around the
original parameter.
Note some of the users can likely use dev->fwnode directly instead of
indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not
guaranteed to be set for all, so this has to be investigated on case to
case basis (by people who can actually test with the HW).

Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read. Ternary
operator has three arguments and with wrapping might lead to quite
long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary
file.

MediaTek driver updates for v6.15
This adds entries for new and missing SoCs in the MediaTek SoCInfo
driver (MT8370AV/AZA, MT8390AV/AZA) and an extra entry for a new
revision of the MT8395AV/ZA SoC.
The MediaTek SoCInfo driver also gets its SoC attribute information
restructured: now the family, machine and soc_id fields are correctly
populated.
MT8188 gains support for the secondary Display Parallel Interface
used for HDMI, and for the Display Stream Compression component
routing through mmsys and mutex tables.
All of the MMSYS drivers get an important overhaul: it was found that,
in multiple cases, the tables contained wrong mask/value pairs, hence
those were doing either nothing or breaking routings.
The mmsys tables were converted to use a newly introduced macro that
will perform a compile time check, making sure that each table entry's
value fits in the declared register mask.
Thanks to the new macro, multiple MediaTek SoCs got multiple fixes in
their MMSYS tables, addressing issues that were severely impacting the
functionality of the display controller pipelines.

The mmsys driver reads the routing table and writes to the
hardware `val & mask`, but multiple entries in the mmsys
routing table for the MT8365 SoC are setting a 0x0 mask:
this effectively writes .. nothing .. to the hardware.
That would never work, and if the display controller was
actually working with the mmsys doing no routing at all,
that was only because the bootloader was correctly setting
the display controller routing registers before booting the
kernel, and the mmsys was never reset.
Make this table to actually set the routing by adding the
correct register masks to it.
While at it, also change MOUT val definitions to BIT(x), as
the MOUT registers are effectively checking for each bit to
enable output to the corresponding HW.
Please note that, for this SoC, only the MOUT registers are
checking bits (as those can enable multiple outputs), while
the others are purely reading a number to select an input.

The mmsys routing table for this SoC was effectively missing

Every MediaTek SoC with multimedia capabilities has an array of
structure mtk_mmsys_routes that defines a multimedia connection
between hardware components.
This connection is activated by writing a (masked) value in each
specific register, and the association between from->to path and
value to write is expressed as an entry in that array.
Failing to set the right path does not give any meaningful error
and makes things to simply not work as the data will either not
be retrieved from the right input port, or will be written to
the wrong output port (or both): since a misconfiguration may
effectively still be a possibly correct configuration at the HW
level, this may be only giving side effects in terms of simply
getting no functionality but, again, no errors.
In order to reduce room for mistakes in declarations of the
mmsys routes, add a macro that compile-time checks that the
provided value does at least fit in the register mask.

The VDO1_MERGE4 hardware (merge5 software component) should be
set to enable output to DPI1_SEL by setting BIT(2) but, despite
the intention being exactly that, this won't work because the
declared register mask is wrong as it is set as GENMASK(1, 0).
Register MERGE4_MOUT_EN in VDO1 has four used bits [3, 0] so
fix the mask to reflect that.
That, in turn, allows the mmsys driver to actually set BIT(2)
in this register, fixing the MERGE4 output to DPI1 selection.

The recently introduced SoC attribute info rework avoided modifying the

So, fix the dev_info format to display SoC family and name attribute

rtkit messages as communication with the DCP firmware for framebuffer
swaps or input events are time critical so use WQ_HIGHPRI to prevent
user space CPU load to increase latency.
With kwin_wayland 6's explicit sync mode user space load was able to
delay the IOMFB rtkit communication enough to miss vsync for surface
swaps. Minimal test scenario is constantly resizing a glxgears
Xwayland window.

The syscon helper device_node_to_regmap() is used to fetch a regmap
registered to a device node. It also currently creates this regmap
if the node did not already have a regmap associated with it. This
should only be used on "syscon" nodes. This driver is not such a
device and instead uses device_node_to_regmap() on its own node as
a hacky way to create a regmap for itself.
This will not work going forward and so we should create our regmap
the normal way by defining our regmap_config, fetching our memory
resource, then using the normal regmap_init_mmio() function.
