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).

The function log_non_standard_event() is responsible for logging
platform-specific or vendor-defined RAS (Reliability, Availability, and
Serviceability) events. Currently, this function is only available within the
RAS subsystem, preventing external modules from leveraging its capabilities.
Export it to drivers to log non-standard RAS events via EDAC.

TEE protected DMA-bufs for v6.18
- Allocates protected DMA-bufs from a DMA-heap instantiated from the TEE
subsystem.
- The DMA-heap uses a protected memory pool provided by the backend TEE
driver, allowing it to choose how to allocate the protected physical
memory.
- Three use-cases (Secure Video Playback, Trusted UI, and Secure Video
Recording) have been identified so far to serve as examples of what
can be expected.
- The use-cases have predefined DMA-heap names,
"protected,secure-video", "protected,trusted-ui", and
"protected,secure-video-record". The backend driver registers protected
memory pools for the use-cases it supports.

In alloc_debug_processing() we can call validate_slab_ptr() upfront and

This will make it clear where we currently cast struct slab to folio
only to check the slab type, and allow to change the implementation
later with memdesc conversion.
For now use a struct page based implementation instead of struct folio
to be compatible with further upcoming changes.

generic_delete_inode() is rather misleading for what the routine is

Qualcomm TEE (QTEE) hosts Trusted Applications (TAs) and services in
the secure world, accessed via objects. A QTEE client can invoke these
objects to request services. Similarly, QTEE can request services from
the nonsecure world using objects exported to the secure world.
Add low-level primitives to facilitate the invocation of objects hosted
in QTEE, as well as those hosted in the nonsecure world.
If support for object invocation is available, the qcom_scm allocates
a dedicated child platform device. The driver for this device communicates
with QTEE using low-level primitives.

Clean-up a couple of clock binding related issues in the the X-Gene DTS.
CPU and I2C nodes aren't clock providers and shouldn't have
"#clock-cells" properties.
A fixed-clock only provides 1 clock, so "#clock-cells" must be 0. The
preferred node name is "clock-<freq>" as well.
The "type" property is undocumented and unused, so drop it.

This pull request contains Broadcom ARM64-based SoCs Device Tree updates
for 6.18, please pull the following:
- Krzysztof fixes a DTC warning for the ARM GIC in bcm2712.dtsi
- Ivan adds the pin controller node(s), an additional GPIO controller,
the second SDHCI controller node for SDIO Wi-Fi, and the UARTA for
Bluetooth to the BCM2712 DTS (Raspberry Pi 5)
- Stanimir adds the Ethernet DT node and enables it for the RP1 sister
chip
- Andrea deletes a number of redundant PCIe DT node enablement, updates
a comment to describe the relationship between bcm2712 and RP1 and
finally enables the USB controllers with RP1

Samsung DTS ARM changes for v6.18
1. Drop S3C2416 SoC from bindings, because it was removed from kernel
in 2023.
2. Add Ethernet attached via SROM controller (memory bus) on SMDK5250.
This wasn't tested, but code should work just like it is working on
Exynos5410-based boards.

Having a platform need a mach-* directory should be seen as a negative,
it means the platform needs special non-standard handling. ARM64 support
does not allow mach-* directories at all. While we may not get to that
given all the non-standard architectures we support, we should still try
to get as close as we can and reduce the number of mach directories.
The mach-hpe/ directory and files, provides just one "feature":
having the kernel print the machine name if the DTB does not also contain
a "model" string (which they always do). To reduce the number of mach-*
directories let's do without that feature and remove this directory.
Note, we drop the l2c_aux_mask = ~0 line, but this is safe as
the fallback GENERIC_DT machine has that as the default.

INITRAMFS_PRESERVE_MTIME is only used in init/initramfs.c and
init/initramfs_test.c. Hence add a dependency on BLK_DEV_INITRD, to
prevent asking the user about this feature when configuring a kernel
without initramfs support.
