Pull SoC driver updates from Arnd Bergmann:
"There are lots of minor updates for driver subsystems managed through
the soc tree (turris-omnia platform, cache driver, tee drivers,
arm-cci, bus, memory) as well as soc vendor specific drivers
(starfive, xilinx, microchip, nxp, amlogic, imx, renesas, samsung, ti,
nvidia).
The more notable changes are:
- Larger updates for Qualcomm SoCs including support for SM8950
(Maili) SM8975 (Hawi), Glymur, Shikra, and IPQ5424
- Added SoC support for Exynos5515, Tegra264, Tegra410, R8A774A3, and
MT8167 in existing drivers
- Arm SCMI firmware driver support for ACPI PCC transport and module
autoloading of protocol specific drivers
- Apple crash log support for CrgA embedded controller"

Qualcomm driver updates for v7.4 (second attempt)
Add UBWC 7.0 configuration for Hawi and Maili, and reuse Glymur's UBWC
configuration for Nord.
Parse Glymur's DDR information from SMEM, including its frequency plan and
highest bank bit. Correct DDR frequency overflow and byte order, and handle
unrecognized DDR layouts correctly.
Configure dedicated LLCC slices for the IPQ5424 PPE and Wi-Fi datapaths,
adjust the CPU slice, and propagate errors from optional IRQ lookup.
Allow the GENI serial-engine driver to be selected on 32-bit Qualcomm SoCs
such as Kuno. Fix firmware loading bounds, endianness, and writes to
read-only firmware.
Allow QSEECOM on the Glymur-based HP EliteBook X G2q 14 AI, Lenovo Yoga
Slim 7x Gen11, and Asus Zenbook A14 (UX3407NA), enabling EFI variable
access on the HP and Asus laptops. Release SCM reserved memory on probe
failure or unbind, and limit Qualcomm firmware Kconfig options to Qualcomm
platforms.
Defer PMIC GLINK altmode work until devices resume to avoid accessing
suspended I2C controllers.
Fix cleanup of failed APR service registrations to prevent stale lookups,
and remove unused APR device-ID matching.
Add the SM7250 SoC ID, correct SMSM and SMP2P I/O annotations, and clean
up RPMh kernel-doc and redundant IRQ error messages.
Document the Kuno SCM interface, Shikra CTCU fallback, and Milos CPU
bandwidth monitor. Add Abel Vesa as a Qualcomm SoC reviewer.

SMCCC-discovered firmware services are currently represented by separate
platform devices, such as smccc_trng and arm-cca-dev. Those devices do not
represent independent DT/ACPI-described platform resources; they are
features of the SMCCC firmware interface.
Add an Arm SMCCC bus for services discovered through the SMCCC firmware
interface. The bus provides SMCCC device and driver registration
helpers, function ID based matching, modalias generation, and a sysfs
modalias attribute so SMCCC service drivers can bind to discovered
firmware services and autoload as modules.
Follow-up changes can then register SMCCC firmware services as arm-smccc
devices instead of creating independent per-feature platform devices.
Based on arm_ffa code

SCMI client drivers already describe their bus match data with
MODULE_DEVICE_TABLE(scmi, ...), but modpost does not know how to consume
SCMI device tables. As a result, SCMI modules do not get generated module
aliases from their id tables.
Move struct scmi_device_id to mod_devicetable.h so it has a fixed layout
visible to modpost, add the corresponding generated offsets and teach
file2alias to emit scmi:<protocol>:<name> aliases.
Use the same stable alias format for SCMI device uevents and sysfs
modaliases. The previous string included the instance-specific device
name, which is not useful for matching modules.

apr_device_id was introduced in commit 6adba21eb434 ("soc: qcom: Add APR
bus driver") in 2018, and since then not a single driver made use of it.
So drop the unused id_table pointer from struct apr_driver and move
APR_NAME_SIZE to the apr header which still has a usage of it.
Note that with the id_table being NULL apr_device_match() degrades to just
of_driver_match_device(), so replace this callback accordingly.

Pull SCSI updates from James Bottomley:
"One new driver: leapraid (similar to mpi3mr but OK'd by Broadcom). The
usual suspects for driver updates (ufs, qla2xxx, smartpqi, zfcp, fnic,
ibmvfc) plus a few small core updates: a fix for an uninitialized sg
list pad bytes plus the removal of the dma mask check for max sectors.
The big update in the sd driver is mostly code refactoring for obscure
error leg handling"

<linux/mod_devicetable.h> is included transitively in nearly every
driver in an x86_64 allmodconfig build of v7.1:
$ find drivers -name \*.o -not -name \*.mod.o | wc -l
21330
$ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
17038
The result is that even when touching an obscure device id struct most
of the kernel needs to be recompiled. Given that each driver typically
only needs one or two of these structures, splitting into per subsystem
headers and only including what is really needed reduces the amount of
needed recompilation.
Implement the first step and define each device id struct in a separate
header (together with its associated #defines).
<linux/mod_devicetable.h> is modified to include all the new headers to
continue to provide the same symbols.
Several headers currently include <linux/mod_devicetable.h>, those that
are most lukrative to include only their subsystem headers only are:
$ git -C source grep -l mod_devicetable.h include/linux | while read h; do echo -n "$h:"; find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l $h | wc -l; done | sort -t: -k2 -n -r | head

include/linux/phy.h:733
struct cpu_feature isn't really a device_id struct. That is kept in
<linux/mod_devicetable.h> for now.
