4c7b77a716 kernel/timeout: Add absolute timeout APIs
Add support for "absolute" timeouts, which are expressed relative to
system uptime instead of deltas from current time.  These allow for
more race-resistant code to be written by allowing application code to
do a single timeout computation, once, and then reuse the timeout
value even if the thread wakes up and needs to suspend again later.

cfeb07eded kernel/timeout: Enable 64 bit timeout precision
Add a CONFIG_TIMEOUT_64BIT kconfig that, when selected, makes the
k_ticks_t used in timeout computations pervasively 64 bit.  This will
allow much longer timeouts and much faster (i.e. more precise) tick
rates.  It also enables the use of absolute (not delta) timeouts in an
upcoming commit.

7832738ae9 kernel/timeout: Make timeout arguments an opaque type
Add a k_timeout_t type, and use it everywhere that kernel API
functions were accepting a millisecond timeout argument.  Instead of
forcing milliseconds everywhere (which are often not integrally
representable as system ticks), do the conversion to ticks at the
point where the timeout is created.  This avoids an extra unit
conversion in some application code, and allows us to express the
timeout in units other than milliseconds to achieve greater precision.

The existing K_MSEC() et. al. macros now return initializers for a
k_timeout_t.

The K_NO_WAIT and K_FOREVER constants have now become k_timeout_t
values, which means they cannot be operated on as integers.
Applications which have their own APIs that need to inspect these
vs. user-provided timeouts can now use a K_TIMEOUT_EQ() predicate to
test for equality.

Timer drivers, which receive an integer tick count in ther
z_clock_set_timeout() functions, now use the integer-valued
K_TICKS_FOREVER constant instead of K_FOREVER.

For the initial release, to preserve source compatibility, a
CONFIG_LEGACY_TIMEOUT_API kconfig is provided.  When true, the
k_timeout_t will remain a compatible 32 bit value that will work with
any legacy Zephyr application.

Some subsystems present timeout (or timeout-like) values to their own
users as APIs that would re-use the kernel's own constants and
conventions.  These will require some minor design work to adapt to
the new scheme (in most cases just using k_timeout_t directly in their
own API), and they have not been changed in this patch, instead
selecting CONFIG_LEGACY_TIMEOUT_API via kconfig.  These subsystems
include: CAN Bus, the Microbit display driver, I2S, LoRa modem
drivers, the UART Async API, Video hardware drivers, the console
subsystem, and the network buffer abstraction.

k_sleep() now takes a k_timeout_t argument, with a k_msleep() variant
provided that works identically to the original API.

Most of the changes here are just type/configuration management and
documentation, but there are logic changes in mempool, where a loop
that used a timeout numerically has been reworked using a new
z_timeout_end_calc() predicate.  Also in queue.c, a (when POLL was
enabled) a similar loop was needlessly used to try to retry the
k_poll() call after a spurious failure.  But k_poll() does not fail
spuriously, so the loop was removed.

32bb2395c2 timeout: Fix up API usage
Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them.  Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:

+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
  values for equality (e.g. with K_FOREVER or K_NO_WAIT).

+ Adding a k_msleep() synonym for k_sleep() which can continue to take
  integral arguments as k_sleep() moves away to timeout arguments.

+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
  generate timeout arguments.

+ Removing the usage of K_NO_WAIT as the final argument to
  K_THREAD_DEFINE().  This is just a count of milliseconds and we need
  to use a zero.

This patch include no logic changes and should not affect generated
code at all.

as interrupt nesting is not supported on the current RISV-C

that in the codebase (see #23593).

84921c53b1 tests: kernel: interrupt: Rework nested interrupt test
The current nested interrupt test implementation is both buggy and
fundamentally flawed because it does not trigger a higher priority
interrupt from a lower priority interrupt context and relies on the
system timer interrupt, which is not fully governed by the test;
moreover, the current implementation does not properly validate the
test results and can report success if no interrupt is triggered and
serviced at all.

This commit reworks this test to have the following well-defined
and logical procedure:

1. [thread] Trigger IRQ 0 (lower priority)
2. [isr0] Set ISR 0 result token and trigger IRQ 1 (higher priority)
3. [isr1] Set ISR 1 result token and return
4. [isr0] Validate ISR 1 result token and return
5. [thread] Validate ISR 0 result token

The reworked test scenario ensures that the interrupt nesting works
properly and any abnormal conditions are detected (e.g. interrupts not
triggering at all, or ISR 1 not being nested under ISR 0).

407b49b35c cmake: use find_package to locate Zephyr
Using find_package to locate Zephyr.

Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.

Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.

It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.

c3ec5db6d2 devicetree.h: add accessor API for nodes and properties
This is joint work with Kumar Gala (see signed-off-by).

Add helper macros which abstract the "true names" of each of the four
types of node identifier we intend to support (e.g. DT_ALIAS(),
DT_INST()).

These can be passed to a new DT_PROP() macro which can be used to read
the value of a devicetree property given a node identifier from one of
these four other macros, and the as-a-c-token name of the property.
Add other accessor macros and tests as well.

Add some convenience APIs for writing device drivers based on instance
numbers as well. Drivers can "#define DT_DRV_COMPAT driver_compatible"
at the top of the file, then utilize these DT_INST_* macros to access
various property defines.

For example, the uart_sifive driver can do:

  #define DT_DRV_COMPAT sifive_uart0

Then use DT_INST macros like:

  .port         = DT_INST_REG_ADDR(0),
  .sys_clk_freq = DT_INST_PROP(0, clock_frequency),

For convenience working with specific hardware, also add:

  <devicetree/gpio.h>
  <devicetree/adc.h>
  <devicetree/spi.h>

Recently added test for pthread_getname_np()/pthread_setname_np()
functions used uninitialized array value. As we can't check behavior
for arbitrary uninitialized value, but at most NULL value, make the
test calls to explicitly use NULL, to make the test intent clear
(instead of for example initializing the original array with zeros).

Also, these test cases use variable names not consistent with Zephyr
codestyle, and named to generically to cause confuse when used in a
general context of the test_posix_pthread_execution() function, so
rename them to be specific. (And alternative would be to separate
pthread_getname_np()/pthread_setname_np() tests into a separate
function, but it was indeed practical to piggyback them on existing
test_posix_pthread_execution()).

dd75bccaca dts: bindings: Fix xlnx,ttcps binding compat
The `xlnx,ttcps` binding, despite having the file name of
`xlnx,ttcps.yaml`, had the compatible property of `cdns,ttc`.

While it is true that the Xilinx ZynqMP platform embeds the Cadence
Triple Timer Counter (TTC) IP core, its TTC differs from the original
Cadence core in that it implements 32-bit counters, instead of the
16-bit counters defined in the original; hence, the Xilinx variant is
not compatible with the original Cadence version and should be treated
as a different device.

This commit changes the `xlnx,ttcps.yaml` compatible property to
`xlnx,ttcps` for the above reasons.

The `tests/kernel/context` test fails for the `qemu_cortex_r5` when the
icount emulation mode is used, because the Xilinx QEMU ignores the WFI
instruction when the icount parameter is specified.

This will be fixed in the Zephyr SDK 0.11.3 and this commit must be
reverted once the CI is updated to use this new SDK version.

For more details, see zephyrproject-rtos/sdk-ng#191.
