data fixes for things that weren't used yet. One thing that's new here in the
core is SSC spread spectrum support (SSC) in the clk provider API. The idea is
that DT authors will configure SSC for certain clks and they'll be configured
at clk provider registration time or when a consumer device is probed, similar
to how we handle assigned clk rates or parents.
On the clk driver side we have Qualcomm adding almost half the diff because
they add support for 4 different SoCs and then a long tail of other SoCs like
Mediatek, Renesas, Rockchip, SpaceMiT, etc. add more SoC support this time
around. Luckily it's mostly clk data for these new SoCs because the actual
clk_ops are already there. Beyond the new drivers we get all the little fixups
for more compilation coverage or usage of more modern APIs. That all looks
normal.
Finally, I kinda buried the lead, I'm bringing on Brian and Jerome to help out
with maintaining the clk subsystem. The current working model is already
semi-distributed in that silicon vendors typically take care of their drivers
and send me pull requests but I'm becoming a bottleneck for new drivers and
core framework review because this has become a 100% volunteer effort on my
part. Mike is stepping down after all these years (thanks Mike!) and that jump
started the conversation around finding co-maintainers. Brian and Jerome have
graciously offered to help me with the work load, meaning in the future they'll
be sending pull requests and committing directly to the clk.git tree. They've
both been around on the list for a while, I've met them both in person, and
they've been making changes to the core clk framework along with helping review
patches so I'm pretty confident this will work well.

Describe an AMD MicroBlaze/V BRAM-based remote processor controlled
through the remoteproc framework.
The binding models a soft-core processor subsystem instantiated in AMD
programmable logic and using dual-port BRAM for firmware storage and
execution. The remoteproc device is represented as a child node whose
reg property describes the firmware memory window in the processor-local
address space. The parent bus node provides standard devicetree address
translation through ranges so Linux can access the same BRAM through the
system physical address space.
A clock input feeds the soft-core processor subsystem, and an active-low
reset GPIO holds the processor in reset until firmware loading completes.
The firmware-name property is optional.

SHM bridge creation is required to enable memory protection for both
remoteproc metadata and its memory region on Qualcomm SoCs like Glymur
running non-Gunyah based Hypervisors, unlike Kaanapali.
Having Glymur fall back to the Kaanapali binding is therefore incorrect
and breaks subsystem restart on Glymur.
Fix this by decoupling Glymur SoCCP PAS from Kaanapali and registering
it as its own binding.

Add names to the memory-region-names for easier identification of memory
regions. As the meaning of the second memory region can be different
also require the use of memory-region-names if memory-region is in use.

Split up the region reserved for the firmware image in more specific
sections to expose the full fixed layout. Especially the LPM metadata
section is important for bootloaders as it contains information about
how to exit IO+DDR. This is read by the bootloader but is written by the
firmware.

Add remote processor PAS loader for Kaanapali CDSP processor, compatible
with earlier SM8550 with minor difference: one more sixth "shutdown-ack"
interrupt. It is not compatible with SM8650 because one memory region
"global_sync_mem" is not managed by kernel on Kaanapali so it is removed
in the remoteproc cdsp node.

Merge the support for loading and managing TustZone-based remote
processors found in the Qualcomm Glymur platform from a shared topic
branch, as it's a mix of qcom-soc and remoteproc patches.
On most Qualcomm platforms, the Qualcomm Hypervisor Execution
Environment (QHEE) is either used as a standalone hypervisor or
co-exists as a module with the Gunyah hypervisor. When QHEE is
present, it configures firmware streams for remote processors.
If QHEE is not available, the operating system must perform
these configurations instead and for that remote processor
firmware stream should be presented to the operating system.
To support this, add the iommus property as an optional property
for PAS-supported devices.

One SDM845 board uses cx-supply, which is not allowed by the bindings,

The SDM845 SLPI binding already allows lcx and lmx domains, thus the
cx-supply seems like a fake name for something else, e.g. some
enable pin. The qcom_q6v5_pas.c driver parses cx-supply, so it is an
