Martí Bolívar 63d5529a0d devicetree: re-work DT_INST_FOREACH()
Due to the use of UTIL_EVAL*() macros, the UTIL_LISTIFY() macro used
by DT_INST_FOREACH(foo) can cause long build errors when there is a
build error in the expansion for "foo". More than a thousand lines of
build error output have been observed for an error in a single line of
faulty C.

To improve the situation, re-work the implementation details so the
errors are a bit shorter and easier to read. The use of COND_CODE_1
still makes the error messages quite long, due to GCC generating notes
for various intermediate expansions (__DEBRACKET,
__GET_ARG_2_DEBRACKET, __COND_CODE, Z_COND_CODE_1, COND_CODE1), but
it's better than the long list of UTIL_EVAL notes.

Peter Bigot 8bd676ed38 sys: onoff: generalize and shorten API
The original API was misnamed, as the intent was to provide a manager
that decoupled state management from the service that needed to be
turned on or off.  Update all the names, shortening them where
appropriate removing unncessary internal components like _service.

Also remove some API that misled developers into believing that onoff
managers are normally expected to be exposed directly to consumers.
While this is a use case, in most situations there are service or
client-specific actions that need to be coupled to transition events.

Peter Bigot fadd98aad2 sys: add generic asynchronous notification infrastructure
k_poll() for a signal is often desired for notification of completion
of asynchronous operations, but there are APIs where it may be
necessary to invoke "asynchronous" operations from contexts where
sleep is disallowed, or before the kernel has been initialized.
Extract the general notification solution from the on-off service into
a utility that can be used for other APIs.

Also move documentation out to a resource management section.

Jordan Yates a038dc76f1 bluetooth: host: Dynamic bt_conn_le_create timeout
Extends the bt_conn_le_create_param struct to provide the option
to set a custom timeout for the initiation of the connection.

The logic for the default values of window_coded and interval_coded
were moved to conn.c in order to resolve all defaults for the
create_param struct at a single location.

Timeout is not added as a parameter to the BT_CONN_LE_CREATE_PARAM
macro due to the expectation that CONFIG_BT_CREATE_CONN_TIMEOUT
will be the typical value that users will expect.

Robert Lubos 1fb418df4c net: ieee802154_radio: Allow to specify TX mode
Even though radio driver can report in its capabilities that it does
support CSMA CA, there's no way in the driver to select how the frame
should be transmitted (with CSMA or without). As layers above radio
driver (Thread, Zigbee) can expect that both TX modes are available, we
need to extend the API to allow either of these modes.

This commits extends the API `tx` function with an extra parameter,
`ieee802154_tx_mode`, which informs the driver how the packet should be
transmitted. Currently, the following modes are specified:
* direct (regular tx, no cca, just how it worked so far),
* CCA before transmission,
* CSMA CA before transmission,
* delayed TX,
* delayed TX with CCA

Assume that radios that reported CSMA CA capability transmit in CSMA CA
mode by default, all others will support direct mode.

The current context preservation implementation saves the spsr and
lr_irq registers, which contain the cpsr and pc register values of the

Andy Ross 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.

Andy Ross 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.

Carlo Caione 99a8155914 arm: AArch64: Add support for nested exception handlers
In the current implementation both SPSR and ELR registers are saved with

To support nested IRQs we have to save those on the stack when entering

the ESF and the initial stack and take care to restore them for new
