Support for PRU clients to acquire a control reference to the PRU
instances is introduced, and the PRU now allows specifying firmware-name
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
check of the firmware image is introduced in the Mediatek driver.
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
driver, and support for the PAS driver to carve out DSM memory for the
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
to strlcpy()

The power domains exposed by the AOSS QMP driver control the load state
resources linked to modem, adsp, cdsp remoteprocs. These are used to
notify the Always on Subsystem (AOSS) that a particular co-processor is
up/down. AOSS uses this information to wait for the co-processors to
suspend before starting its sleep sequence.
These co-processors enter low-power modes independent to that of the
application processor and the load state resources linked to them are
expected to remain unaltered across system suspend/resume cycles. To
achieve this behavior lets stop using the power-domains exposed by the
AOSS QMP node and replace them with generic qmp_send interface instead.

make the driver directly enable the xo, sleep and core clocks.
The three clocks are previously toggled through the clock controller,
but that means the same hardware block needs to be mapped in both
drivers. Making the remoteproc driver enable the clocks is a nop when
using the clock controller, but allow us to remove the clocks from the
