`#defines` do NOT sepecify a type. They will either adopt a native
system type or type of the value that was passed into the expression.
This can lead to warnings such as, "warning: comparison of integer
expressions of different signedness: 'uint32_t' {aka 'unsigned int'}
and 'int' [-Wsign-compare]".
By casting expressions, such as `MAX_TICKS` to `k_ticks_t`, we can
force the appropriate types and resolve these warnings.

This is a follow-up to commits cf871aec64
and 205e684958.
It turns out that the current implementation of the nrf_rtc_timer may
still fail to properly handle a timeout if that timeout is set in very
specific conditions - when a previously set timeout is about to expire.
When that happens, the new timeout is handled 512 seconds later (when
the system timer overflows) than it should be.
A recently added nrf_rtc_timer test case (test_tight_rescheduling)
exposes this problem and this commit fixes it by adding examination
of COMPARE events that appear during setting of the CC register value
for a given timeout.

There is no need to disable interrupts while just checking if
a channel needs to be processed in the ISR, as that section
does not contain anything that needs to be protected against
overwriting from some other context. In particular, if a given
timeout is changed or even aborted while its event is being
checked, this will be correctly handled in the code that follows
and that checks the expiration time.

Values to be set to the comparator need to be specified in RTC cycles,
not ticks, so the initial value used in the tickless mode needs to be
MAX_CYCLES, otherwise when CONFIG_SYS_CLOCK_TICKS_PER_SEC is set to
a value less then the RTC frequency, the initially configured timeout
will be unnecessarily shorter.
On the occassion, remove also the call to counter() when setting the
initial timeout value in non-tickless mode. RTC is cleared a few lines
above, so at this point it will most likely be 0, and even if it was
not, compare_set() would properly handle a target time value that had
already passed.

setting CC and CC was behind the counter because of risk of setting

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

On L0 series, LSI runs at 37KHz while LPTIM driver only supports speeds
up to 32768Hz (to avoid counter overflow). Consequence is a time running
faster than reality (x1.13)
Solution to this is the implementation of the LPTIM prescaler support.
While moving driver configuration from Kconfig to DT, this case was
not taken into account and the effect was LPTIM counter overflow which
consequence is worse than the slightly faster timer.

needs to be adapted to get a precise tick to LPTIM freq ratio.
This adaptation was done easily using Kconfig up to now (under

Since driver is configured using device tree, this method should

* tests/kernel/sleep/kernel.common.timing
* tests/kernel/tickless/tickless_concept/kernel.tickless.concept
