Arm SCMI updates for v7.1
This batch mainly improves SCMI robustness on systems where the SCP does
not generate completion interrupts, and includes two small follow-up
cleanups in the SCMI core.
The main functional change adds support for the new DT property
'arm,no-completion-irq'. When present for mailbox/shared-memory based
SCMI implementations, the driver forces SCMI operations into polling
mode so affected platforms can continue to operate even with broken
firmware interrupt behavior.
In addition, it
- replaces open-coded size rounding in the base protocol path with
round_up() for clarity, with no functional change
- updates the SCMI quirk snippet macro implementation so quirk handlers
can use break and continue directly when invoked inside loop contexts

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
Document new property arm,no-completion-irq . This optional property
is intended for hardware that does not generate completion interrupts
and can be used to unconditionally enable forced polling mode of
operation.
With this property set, such implementations which do not generate
interrupts can be interacted with, until they are fixed to generate
interrupts properly.
Note that, because the original base protocol exchange also requires
some sort of completion mechanism, it is not possible to query SCMI
itself for this property and it must be described in DT. While this
does look a bit like policy, the SCMI provider is part of the
hardware, hence DT.

In a typical system using the Samsung S2MPG10 PMIC, an S2MPG11 is used
as a sub-PMIC.
The interface for both is the ACPM firmware protocol, so update the
binding to allow the relevant node and update the example here to
describe the connection for both PMICs.
Since we have two PMICs here, but can not use the 'reg' property (as
the addressing is based on software, i.e. the ACPM firmware), the node
names reflect that with their respective suffix. The existing 'pmic'
therefore becomes deprecated in favour of 'pmic-1'.
While at it, update the example.

Merge series from André Draszik <andre.draszik@linaro.org>:
This series extends the existing S2MPG10 PMIC driver to add support for
the regulators, and adds new S2MPG11 core and regulator drivers.
The patches are kept together in one series, due to S2MPG11 and its
regulators being very similar to S2MPG10.
The Samsung S2MPG11 PMIC is a Power Management IC for mobile
applications with buck converters, various LDOs, power meters, and
additional GPIO interfaces. It typically complements an S2MPG10 PMIC in
a main/sub configuration as the sub-PMIC and both are used on the
Google Pixel 6 and 6 Pro (oriole / raven).
A DT update for Oriole / Raven to enable these is required which I will
send out separately.
The SCU MU driver has already supported the simple and efficient single-TX
and single-RX channel layout since 2021. The older multi-channel MU
configurations (tx0..tx3 and rx0..rx3) are less efficient in practice and
not needed.
Mark these legacy mbox-names and mboxes tuple layouts as deprecated in the
binding schema. The driver continues to support them for backward
compatibility in case firmware publishes the legacy properties.
The example section is updated accordingly to demonstrate the recommended
layout.

Updates the Device Tree bindings for Xilinx firmware by introducing
conditional schema references for the pinctrl node.
Previously, the pinctrl node directly referenced
xlnx,zynqmp-pinctrl.yaml. However, this patch modifies the schema to
conditionally apply the correct pinctrl schema based on the compatible
property. Specifically:
- If compatible contains "xlnx,zynqmp-pinctrl", reference
xlnx,zynqmp-pinctrl.yaml.
- If compatible contains "xlnx,versal-pinctrl", reference
xlnx,versal-pinctrl.yaml.
Additionally, an example entry for "xlnx,versal-pinctrl" has been
added under the examples section.

Arm SCMI updates/fixes for v6.18
These SCMI changes bring a mix of improvements, fixes, and cleanups:
1. Device Tree bindings - allow multiple SCMI instances by suffixing
node names (Nikunj Kela).
2. Code hardening - constify both scmi_{transport,voltage_proto}_ops
so they reside in read-only memory (Christophe JAILLET).
3. VirtIO transport initialization - set DRIVER_OK before SCMI probing
to prevent potential stalls; while recent rework removes the practical
risk, this ensures correctness (Junnan Wu).
4. Quirk handling - fix a critical bug by preventing writes to string
constants, avoiding faults in read-only memory (Johan Hovold).
5. i.MX SCMI MISC protocol - extend support to discover board info,
retrieve configuration and build data, and document the new
MISC_BOARD_INFO command; all handled gracefully if unsupported (Peng Fan).
6. Logging cleanup - simplify device tree node name logging by using
the %pOF format to print full paths (Krzysztof Kozlowski).

Pull SoC devicetree updates from Arnd Bergmann:
"There are a few new variants of existing chips:
- mt6572 is an older mobile phone chip from mediatek that was
extremely popular a decade ago but never got upstreamed until now
- exynos2200 is a recent high-end mobile phone chip used in a few
Samsung phones like the Galaxy S22
- Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M
(R8A779H0) and used in automotive applications
- Tegra264 is a new chip from NVIDIA, but support is fairly minimal
for now, and not much information is public about it
There are five more chips in a separate branch, as those are new chip
families that I merged along with the necessary infrastructure.
New board support is not that exciting, with a total of 33 newly added
machines here:
- Evaluation platforms for the chips above, plus TI am62d2 and Sophgo
sg2042
- Six 32-bit industrial boards based on stm32, imx6 and am33 chips,
plus eight 64-bit rockchips rk33xx/rk35xx, am62d2, t527, imx8 and
imx95
- Two newly added ASPEED BMC based motherboards, and one that got
removed
- Phones and Tablets based on 32-bit mt6572, tegra30 and 64-bit
msm8976 SoCs
- Three Laptops based on Mediatek mt8186 and Qualcomm Snapdragon X1
- A set-top box based on Amlogic meson-gxm
Updates for existing machines are spread over all the above families.
One notable change here is support for the RP1 I/O chip used in
Raspberry Pi 5"

Arm SCMI updates for v6.16
1. Quirk framework to handle buggy firmware
With SCMI gaining broader adoption across arm64 platforms, it's
increasingly important to address how we consistently manage out-of-spec
SCMI firmware already deployed in the field. This change introduces a
lightweight quirk framework built around static_keys, enabling developers to:
- Define quirks and their match criteria, which can include:
o A list of compatibles ({ comp, comp2, NULL })
o Vendor ID / Sub-Vendor ID
o Firmware implementation version ranges ([Min_Vers, Max_Vers])
Matching proceeds from the most specific (longest match) to the least
specific. NULL entries are treated as wildcards (i.e., match any value).
This flexibility allows matching very specific combinations or just a
general compatible string.
The quirk code blocks/snippets implementing the workaround are placed near
their intended usage and guarded by a static_key that's tied to the quirk.
Once the SCMI core stack is initialized and retrieves platform info via the
base protocol, any matching quirks will have their associated static_keys
enabled.
2. Quirk for Qualcomm X1E platforms
On some Qualcomm X1E platforms, such as the Lenovo ThinkPad T14s, the
SCMI firmware fails to set the FastChannel support bit for PERF_LEVEL_GET,
yet it crashes when the driver attempts to fall back to standard messaging
which is clearly out-of-spec behavior.
To work around this, the new SCMI quirk framework is used to
unconditionally enable FC initialization for this firmware version.
In the future, once the fixed firmware version is identified, an upper
version bound can be added to the quirk match criteria. Alternatively,
matching can be further restricted using a SoC-specific compatible string
if always enabling FC proves problematic elsewhere.
3. Support for NXP i.MX LMM/CPU vendor protocol extensions
The i.MX95 System Manager (SM) implements Logical Machine Management (LMM)
and a CPU protocol to manage Logical Machines (LM) and CPUs (e.g., M7).
These changes integrate the vendor-specific protocol extensions
implementing the LMM and CPU protocols for the i.MX95, facilitating
standardized communication between the operating system and the platform's
firmware, which will be used by remoteproc drivers. The changes also
include the necessary device tree bindings.
4. Miscellaneous cleanups/changes
These mainly include polling support in SCMI raw mode. The cleanups
centralize error logging for SCMI device creation into a single helper
function, consolidate the device matching logic into a single function, and
ensure that devices must have a name for registration—removing support for
unnamed devices when matching drivers and devices for probing. Transport
devices are now excluded from bus matching, and the correct assignment of
the parent device for the arm-scmi platform device is ensured in the
transport drivers.

Add i.MX SCMI Extension protocols bindings for:
- Logic Machine Management(LMM) Protocol
intended for boot, shutdown, and reset of other logical machines (LM).
It is usually used to allow one LM to manager another used as an offload
or accelerator engine..
- CPU Protocol.
allows an agent to start or stop a CPU. It is used to manage auxiliary
CPUs in an LM (e.g. additional cores in an AP cluster).
