Add the pulse_io subsystem API: the public header with the driver
vtable, capability and configuration structs, the SYMBOL and CELL
submission descriptors, sync and async transmit and receive entry
points, and the byte/symbol encoder and decoder helpers.
The channel lifecycle and transfer calls are exposed as syscalls
with userspace verification handlers. Includes the controller
binding, subsystem documentation, release note and maintainer entry.

Introduce a new generic multiplexer (MUX) controller subsystem
modeled on the Linux mux framework. Provides a unified API for
software- and hardware-level signal routers via mux_control_set()
and mux_state_apply(), with userspace syscall handlers and common
devicetree bindings (mux-controller / mux-consumer) for downstream
consumers.

Introduce a clock_monitor driver class that abstracts hardware that
watches one clock against another - frequency-window checkers,
frequency meters, and stuck/lost detectors. The subsystem exposes five
syscalls (configure, start, stop, get_rate, set_source).
clock_monitor_start() begins operation of whatever mode was installed
by configure(): continuous threshold checking in WINDOW mode, or one
measurement in MEASURE mode, whose result is delivered through the
configure-time callback with the device auto-returning to the stopped
state before the callback runs. Repeating measurement is achieved by
calling start() again from the callback; start() and stop() are
ISR-safe. clock_monitor_get_rate() polls the most recent completed
result and is the retrieval path for user mode, where callbacks may
not be installed.
The public header at include/zephyr/drivers/clock_monitor.h documents
the operating modes (WINDOW, MEASURE) and the event bitmap
(EVT_FREQ_HIGH, EVT_FREQ_LOW, EVT_CLOCK_LOST, EVT_MEASURE_DONE),
delivered exclusively through the configure-time callback.

Introduce core support for ARM's SCMI (System Control and
Management Interface). This includes:
* shared memory (SHMEM) driver. This consists of a suite
of functions used to interact with the shared memory area.
* shared memory and doorbell-based transport layer driver.
Data is passed between platform and agent via shared
memory. Signaling is done using polling (PRE_KERNEL) and
doorbells (POST_KERNEL). This makes use of Zephyr MBOX API
(for signaling purposes) and the SHMEM driver (for polling
and data transfer).
* core driver - acts as glue between transport and protocol
layers. Provides synchronized access to transport layer
channels and channel assignment/initialization.
* infrastructure for creating SCMI protocols
This is based on ARM's SCMI Platform Design Document: DEN0056E.

Add Serial Wire Debug Port interface driver API and bit-bang driver.
The driver requires a simple Hardware Interface Circuits (HICs),
where signals CLK, DOUT, DIN, ENn, OE_ENn, RESETn
are connected to board GPIOs and buffered signals SWD_CLK and SWD_DIO
to the target.
Signal OE_ENn controls the direction of the Serial Wire (SWD_DIO),
ENn the buffers SWD_CLK possibly others and enables/disables HIC.

Xen-related Kconfig options were highly dependand on BOARD/SOC xenvm.
It is not correct because Xen support may be used on any board and SoC.
So, Kconfig structure was refactored, now CONFIG_XEN is located in
arch/ directory (same as in Linux kernel) and can be selected for
any Cortex-A arm64 setup (no other platforms are currently supported).
Also remove confusion in Domain 0 naming: Domain-0, initial domain,
Dom0, privileged domain etc. Now all options related to Xen Domain 0
will be controlled by CONFIG_XEN_DOM0.

This enables -Wshadow to warn about shadow variables on
in tree code under arch/, boards/, drivers/, kernel/,
lib/, soc/, and subsys/.
Note that this does not enable it globally because
out-of-tree modules will probably take some time to fix
(or not at all depending on the project), and it would be
great to avoid introduction of any new shadow variables
in the meantime.
Also note that this tries to be done in a minimally
invasive way so it is easy to revert when we enable
-Wshadow globally. Source files under modules/, samples/
and tests/ are currently excluded because there does not
seem to be a trivial way to add -Wshadow there without
going through all CMakeLists.txt to add the option
(as there are 1000+ files to change).

The intention of hardware spinlock is to allow two processors,
that have no alternative mechanism for accomplish synchronization
and mutual exclusion operations, to share resources (such as
memory and/or any other element).
Here, we add the hwspinlock framework, that makes possible to use
those hwspinlock devices and stay platform-independent. Each
platform wishing to support hardware spinlock must describe a
driver using this framework.
