The lp5569 has multiple pwm outputs, and thus implementing the
write_channels api to set multiple values in a single call makes sense.
Implement the write_channels function with a basic range check on the
channel range.
Since the lp5569 supports auto-increment, all of the channels can be
written in one i2c transfer, starting from the pwm register of the
start_channel.

The lp5569 controller supports auto-increment for its registers. This is by
default enabled in the chip, but the driver actively disabled it.
Since auto-increment is useful for writing multiple consecutive registers,
enable the feature. The driver, however, doesn't perform such consecutive
writes and thus the existing behavior is not altered.

k_thread_suspend() is an async API intended to stop any thread in any
state from any context. Some apps just want to use it to "suspend
myself", which is a much (!) simpler operation. Detect that specific
usage as a performance case.

This puts the syscall helpers into the vector code section, and
is a tiny TLB optimization. Before this, worst case scenario is
that there would 2 instruction TLB misses when both the syscall
helpers and the vector code pages are not in TLB cache. With
this change, there would be at most 1 instruction TLB miss as
now the syscall helper and the vector code (which includes
exception handling code and xtensa_do_syscall()) are now in
the same page, and the same TLB entry.

The B_L4S5I_IOT01A Discovery kit does not boot up when using --sysbuild.
The error is caused by slot0_partition which is assigned an address of
0x1000 which overlaps with the boot_partition. Setting the address to
0x10000 fixed it.

This adds support for the single-vector trapping (SVT) model, defined by
SPARC-V8 Embedded (V8E) Architecture Specification. SVT is available in
most LEON processors.
With single-vector trapping enabled, all traps are vectored through a
single trap vector (TBR.A) rather than one 16-byte entry for each trap
type. This improves memory utilization because the full 4 KiB trap table
is not needed.
This implementation uses a two-level of lookup table to find the handler
for the trap type (0..255).
- Execution time is constant.
- Condition flags are preserved.
- The implementation footprint is 60 bytes .text and 284 bytes .rodata.
For comparison, a non-SVT table is always 4096 .text.

Reducing the heap requirement for the hci_ipc sample from
8KiB to 4KiB. It has been tested in various configurations to
work with 2300, but 4KiB was used to provide some leeway for
future updates.
The heap requirement is not documented, and it is unclear why
values lower than 2300 (not exact number) won't boot, and should
be investigated further.
Memory has become a very scarce resource for especially the ISO
builds for the nRF5340, which is why this is getting reduced.

The SSP driver has odd dependency to outside definition of
CONFIG_INTEL_NM. This is in practise tied to SSP hardware
version and always enabled for SSP block version 1.0.

remove the obsolete config setting.

This fixes memory corruption of delayable work when
tests executes unsupported function.
When test (e.g. only_rx_in_chunks) is executed it starts
delayed work for master functionality (with 10 ms delay).
Later when slave function is tried and reports that
function is unsupported, test is terminated (task ends)
but work is still scheduled.
When next test starts it clears work that is already
scheduled:
static void before(void *not_used)
{
ARG_UNUSED(not_used);
memset(&tdata, 0, sizeof(tdata));
this leads to memory corruption and system work queue
tries to remove work but it never does since head/next
pointers are zeroed at that time.
This just adds after function that cancels work
regardless if it was scheduled or not.
