The "qcom,msm8974-mss-pil" binding is still similar enough to MSM8916
to be covered by the same DT schema. The only difference is the
additional "mss-supply", which can be easily handled using a single
if statement.

qcom,q6v5.txt covers multiple SoCs with quite different binding
requirements. Converting this into one DT schema would require
several if statements, making the DT schema overall harder to
read and understand.
To avoid this, follow the example of SC7180/SC7280 and split
"qcom,msm8916-mss-pil" (and the equivalent deprecated "qcom,q6v5-pil"
compatible) into a separate DT schema. The schema is somewhat based
on the one for SC7180/SC7280 but adjusted for the old platforms.
Compared to the old plain text bindings, add missing documentation for
the "bam-dmux" subnode and recommend one particular approach to specify
the MBA/MPSS "memory-region" (the other one is marked as deprecated).

Pull remoteproc updates from Bjorn Andersson:
"This introduces support for the remoteproc on Mediatek MT8188, and
enables caches for MT8186 SCP. It adds support for PRU cores found on
the TI K3 AM62x SoCs.
It moves the recovery work after a firmware crash to an unbound
workqueue, to allow recovery to happen in parallel.
A new DMA API is introduced to release dma_mem for a device.
It adds support a panic handler for the Qualcomm modem remoteproc,
with the goal of having caches flushed in memory dumps for post-mortem
debugging and it introduces a mechanism to wait for the modem firmware
on SM8450 to decrypt part of its memory for post-mortem debugging.
Qualcomm sysmon is restricted to only inform remote processors about
peers that are actually running, to avoid a race where Linux tries to
notify a recovering remote processor about its peers new state. A
mechanism for waiting for the sysmon connection to be established is
also introduced, to avoid out-of-sync updates for rapidly restarting
remote processors.
A number of Devicetree binding cleanups and conversions to YAML are
introduced, to facilitate Devicetree validation. Lastly it introduces
a number of smaller fixes and cleanups in the core and a few different
drivers"

Newer platforms vote for necessary power domains through the power
domain subsystem. For historical reasons older platforms like MSM8916
or MSM8974 still control these as regulators.
Managing them as power domains is preferred since that allows us
to vote for corners instead of raw voltages. Document that those
should be specified as power domains and deprecate using them
through the regulator interface.

Pull remoteproc updates from Bjorn Andersson:
"This introduces device managed versions of functions used to register
remoteproc devices, add support for remoteproc driver specific
resource control, enables remoteproc drivers to specify ELF class and
machine for coredumps. It integrates pm_runtime in the core for
keeping resources active while the remote is booted and holds a wake
source while recoverying a remote processor after a firmware crash.
It refactors the remoteproc device's allocation path to simplify the
logic, fix a few cleanup bugs and to not clone const strings onto the
heap. Debugfs code is simplifies using the DEFINE_SHOW_ATTRIBUTE and a
zero-length array is replaced with flexible-array.
A new remoteproc driver for the JZ47xx VPU is introduced, the Qualcomm
SM8250 gains support for audio, compute and sensor remoteprocs and the
Qualcomm SC7180 modem support is cleaned up and improved.
The Qualcomm glink subsystem-restart driver is merged into the main
glink driver, the Qualcomm sysmon driver is extended to properly
notify remote processors about all other remote processors' state
transitions"

7C retail devices using MSA based boot will result in a fuse combination
which will prevent accesses to MSS PERPH register space where the mpss
clocks and halt-nav reside. However accesses to conn_box_spare0 in TCSR
register space is still permitted so rename the binding appropriately to
qcom,spare-regs and drop all accesses to the MPSS PERPH register space.
