Support for booting the iMX remoteprocs using MMIO, instead of SMCCC is
added. The iMX driver is also extended to support delivering interrupts
from an arbitrary number of vdev.
Support is added to the TI PRU driver, to allow GPMUX to be controlled
from DeviceTree.
The Qualcomm coredump collector is extended to fall back to generating a
full coredump, in the case that the loaded firmware doesn't support
generating minidump. The overly terse MD abbreviation of "MINIDUMP" is
expanded, to make the code easier on the eye.
The list of Qualcomm Sensor Low Power Island (SLPI) instances supported
is cleaned up, and SDM845 is added. SDM630/636/660 support for the modem
subsystem (mss) is added.
All the Qualcomm drivers are transitioned to of_reserved_mem_lookup()
instead of open coding the resolution of reserved-memory regions, to
gain handling of error cases. A couple of drivers are transitioned to
use devm_platform_ioremap_resource_byname().
The stm32 remoteproc driver's PM operations are updated to modern
macros, to avoid the "unused variable"-warning in some configurations.
Drivers are transitioned away from directly including of_device.h.

QCM2290 is more or less a fork of the same design that SM6115 is based
on. As a result, the ADSP and modem found on it are identical.

require any driver changes. Change the allOf:if:properties clauses

On Qualcomm platforms, most subsystems (e.g. audio/modem DSP) are
described as remote processors in the device tree, with a dedicated
node where properties and services related to them can be described.
The Resource Power Manager (RPM) is also such a subsystem, with a
remote processor that is running a special firmware. Unfortunately,
the RPM never got a dedicated node representing it properly in the
device tree. Most of the RPM services are described below a top-level
/smd or /rpm-glink node.
However, SMD/GLINK is just one of the communication channels to the RPM
firmware. For example, the MPM interrupt functionality provided by the
RPM does not use SMD/GLINK but writes directly to a special memory
region allocated by the RPM firmware in combination with a mailbox.
Currently there is no good place in the device tree to describe this
functionality. It doesn't belong below SMD/GLINK but it's not an
independent top-level device either.
Introduce a new "qcom,rpm-proc" compatible that allows describing the
RPM as a remote processor/subsystem like all others. The SMD/GLINK node
is moved to a "smd-edge"/"glink-edge" subnode consistent with other
existing bindings. Additional subnodes (e.g. interrupt-controller for
MPM, rpm-master-stats) can be also added there.
Deprecate using the old top-level /smd node since all SMD edges
are now specified as subnodes of the remote processor.

Semantically glink-edge and glink-rpm-edge are similar: Both describe
the communication channels to a remote processor. The RPM glink-edge is
a special case that needs slightly different properties but otherwise
it is used exactly the same.
To improve consistency use the same "glink-edge" node name also for
glink-rpm-edge. Drop the $nodename from qcom,glink-edge.yaml to avoid
matching the wrong schema. qcom,glink-edge.yaml is always referenced
explicitly from other schemas. This will already ensure that the nodes
are being checked, so it's not necessary to bind to all nodes named
"glink-edge".

The Devicetree bindings document does not have to say in the title that
it is a "Devicetree binding", but instead just describe the hardware.
Most of these have been fixed already, so fix the handful that snuck in.
With this, a meta-schema check can be enabled to catch these
automatically.

With the introduction of the SCMI (System Control and Management
Interface), it is now possible to use the SCMI to handle the
hold boot instead of a dedicated SMC call.
As consequence two configurations are possible:
- without SCMI server on OP-TEE:
use the Linux rcc reset service and use syscon for the MCU hold boot
- With SCMI server on OP-TEE:
use the SCMI reset service for both the MCU reset and the MCU hold boot.
This patch:
- make optional and deprecated the use of the property st,syscfg-tz
which was used to check if the trusted Zone was enable to use scm call,
to manage the hold boot. The reset controller phandle is used instead
to select the configurations.
- make st,syscfg-holdboot optional
- adds properties check on resets definitions.
- adds an example of the SCMI reset service usage.

AM62 family of devices don't have a R5F cluster, instead they have
single core DM R5F. Add new compatible string ti,am62-r5fss to support
this scenario.
When this new compatible is used cluster-mode property can only be set
to value 3 i.e. CLUSTER_MODE_SINGLECORE which is also the default value
in case cluster-mode is not defined in device-tree.
While at it, also sort the compatible lists in alphabetical order.

Support for PRU clients to acquire a control reference to the PRU

in Devicetree. sysfs is requested to be read-only when the remoteproc
instance is consumed by another kernel driver.
Support for the C7xv DSP on AM62A SoC is introduced.
The Devicetree binding for the Qualcomm PAS devices are split up in
multiple files, to better account for the differences in resources
between them. A number of missing Devicetree bindings are added, and the
Qualcomm WCNSS binding is converted to YAML.
A few cleanups are introduced for the Mediatek SCP driver. And a sanity

For Qualcomm SC7280 ADSP support is added, MSM8953 gains ADSP and modem
support, SM6115 and SM8550 gains ADSP, CDSP and modem support, and
support for pronto v3 support (used on e.g. MSM8953) is added.
The Qualcomm modem remoteproc driver is modified to use a no-map
reserved-memory region for it's authentication metadata, in order to
avoid fatal security violations caused by accesses from Linux during
the authentication process.
Support for separate loading of a Devicetree blob is added to the PAS

modem is added as well.
The Qualcomm ADSP remoteproc driver gains support for mapping memory
into specific range using the IOMMU. The sysmon driver is transitioned
