This adds the ability to de-initialization a memory domain.
This requires support in the architecture layer. One usage of
this is to release the resources associated with the domain.
For example, we can release allocated page tables so they can
go back to the pool of page tables to be allocated later.

In commit 7a671993eacf7542a450d62439c012503b7cda2e a change was introduced
that placed variables in llextspecific sections. In the linker script
these are guarded by `#ifdef CONFIG_LLEXT`, but not the corresponding
C code, so these variables are being put in sections that are not
specified in linker scripts. This causes issues with IAR linker,
which warns about these orphan sections.

Add a new parameter to SHMEM's write_message() functon, which is meant to
allow it to perform the required configuration whenever the SCMI stack
(via the SCMI transport layer) wishes to poll for the reply.
For now, don't implement any logic related to this. Thus, no functional
change.

The micsr_* helpers use a two-step MISELECT+MIREG sequence that is not
atomic. If an interrupt fires between writing MISELECT and accessing
MIREG, the handler could modify MISELECT, causing the MIREG operation
to target the wrong indirect register.
Wrap the MISELECT+MIREG sequence in each micsr_* helper with
irq_lock/irq_unlock to prevent preemption during the two-step access.
This ensures all callers are automatically protected without needing
to add locking at each call site.
Move the micsr_* helpers from csr.h into a new icsr.h header to avoid
pulling zephyr/irq.h into csr.h, which causes circular dependencies
on some SoCs. Code that needs indirect CSR access now explicitly
includes icsr.h.

- Move the variable declaration and related code from kernel/timeout.c
to a new kernel/sys_clock_hw_cycles.c file. The motivation is that
both functions are part of the system clock frequency plumbing
(runtime query / update) and don’t naturally fit the responsibilities
of timeout.c, which is otherwise focused on timeout queue management
and tick announcement logic.
- Make sys_clock_hw_cycles_per_sec_runtime_get() (and its
z_impl_sys_clock_hw_cycles_per_sec_runtime_get() implementation)
visible under CONFIG_SYSTEM_CLOCK_HW_CYCLES_PER_SEC_RUNTIME_UPDATE
as well, not only under CONFIG_TIMER_READS_ITS_FREQUENCY_AT_RUNTIME.
This allows callers and time unit conversion helpers to retrieve the
current system timer frequency after runtime clock changes even when
the timer driver does not discover the rate by querying hardware.

Add infrastructure to support updating the system timer frequency at
runtime on platforms where the timer clock rate can change dynamically.
Introduce CONFIG_SYSTEM_CLOCK_HW_CYCLES_PER_SEC_RUNTIME_UPDATE Kconfig
option that enables runtime frequency updates. This option is mutually
exclusive with CPU_FREQ_PER_CPU_SCALING since the system timer frequency
is tracked as a single global value.
Add z_sys_clock_hw_cycles_per_sec_update() API that platforms must call
after applying a system timer clock change. The kernel provides a weak
default implementation that updates the stored frequency value used by
sys_clock_hw_cycles_per_sec().
System timer drivers that cache derived constants or need to reprogram
hardware on frequency changes can provide a strong override of this
function to maintain driver state consistency while ensuring the stored
frequency is also updated.

Refactor bt_tbs_set_uri_scheme_list to take a single string instead
of an array of URIs. This should not affect applications much
in any way (and may actually be easier to use), but simplifies

Additionally it also make the client and server more similar
as bt_tbs_client_read_uri_list just returns it as a single

Add driver for the Infineon SAR ADC peripheral with device tree
binding. The driver uses a generic compatible (infineon,sar-adc)
with an infineon,version property to differentiate IP block
revisions (v2, v3). Features include:
- Single-ended and differential channel configuration
- Configurable resolution (8-12 bits)
- Multiple voltage reference sources (internal, VDDA, VDDA/2, external)
- Channel reference validation against block-level vref-src
- Hardware compensation for SAR v2/v3 single-ended channel limitation
- Interrupt-driven conversion completion
- Integration with peripheral clock control
The driver includes a compile-time per-instance API structure to
correctly report reference voltage to the ADC framework for accurate
raw-to-millivolts conversion.
Tested on CY8CKIT-041S-MAX (SAR v2) and CY8CPROTO-041TP (SAR v3) boards.

When CONFIG_WAITQ_SCALABLE=y, wake up all threads from a post-waitq-walk
callback which is invoked while the scheduler spinlock is still held. This
solves the race condition that was worked around via `no_wake_in_timeout`
flag in k_thread and `is_timeout` parameter of z_sched_wake_thread_locked()
which can now both be dropped.

When CONFIG_WAITQ_SCALABLE=n, the callback invoked by z_sched_waitq_walk()
is allowed to remove the thread provided as argument from the wait queue
(an operation implicitly performed when waking up a thread).
Use this to our advantage when waking threads pending on a k_event by
waking threads as part of the waitq walk callback instead of building
a list of threads to wake and performing the wake outside the callback.
When CONFIG_WAITQ_SCALABLE=n, this allows removing a pointer-sized field
from the thread structure which reduces the overhead of CONFIG_EVENTS=y.
The old implementation (build list in callback and wake outside callback)
is retained and used when CONFIG_WAITQ_SCALABLE=y since we can't modify
the wait queue as part of the walk callback in this situation. This is now
documented above the corresponding field in k_thread structure.

The `Z_GENLIST_LEN` macro declared the loop iterator `node` as
`static`. This causes the variable to be stored in the data segment,
shared across all invocations of the generated `sys_*_len` function.
This makes the function non-reentrant and unsafe in multi-threaded
environments. If an ISR or another thread calls the function
concurrently, the shared iterator state gets corrupted, leading to
incorrect results or infinite loops.
Removing the `static` keyword ensures `node` is allocated on the
stack, making the function thread-safe.

Alif SoCs organize clock control into multiple register regions
(called clock modules in the driver). Bitfields in these modules
are used to manage different clocks in the SoC. Add headers that
define the encoding of the information necessary to operate on
the clocks.
The encoding packs clock control information into a single 32-bit
value that includes clock module and register offset within the
module, clock enable information and clock source information.
Note that alif-clocks-common.h contains the common encoding scheme,
module definitions etc. that could be reused by other Alif SoCs and
alif-ensemble-clocks.h defines the peripheral clock IDs specific to
the Ensemble family (UART 0-7 clocks are added for initial support).
