13f96d439e sys: onoff: support clients using synchronous transitions
The on-off manager infrastructure is designed to robust asynchronous
transition between binary states where multiple clients may be
initiating a transition from any context.  The actual transition is
performed using a manager that tracks the current state and pending
operations.  Requests are initiated by passing a reference to an
onoff_client object that holds client state including the notification
mechanism.

This API may be used in subsystems where the transitions for a
particular driver are always synchronous and isr-ok, e.g. setting a
SoC-controlled GPIO.  In this situation the full on-off manager
infrastructure is wasteful.  All we need is a record of the service
state: off, active count, or error.

Add a data structure and an API that can be used to replace the onoff
manager functionality in a situation where all transitions are isr-ok
and synchronous while retaining compatible behavior from the client
perspective.

Also fixed two tests that were using the object values before

6014e5f441 lib/os/heap: remove big_heap restriction for aligned allocations
After commit 8a6b02b5bf ("lib/os/heap: some code simplification in
sys_heap_aligned_alloc()") it is no longer required to have a "big"
heap for aligned allocations to work on 32-bit targets. While the
natural alignment for returned memory has an offset of 4 within a chunk
unit due to the smaller header size, returning to a chunkid from a
memory pointer with an offset of 8 will fall back onto the proper chunk
number once the 4 is substracted and then divided by 8.

130963ad2f lib/os/heap: add an additional validation criteria
One fundamental validation criteria is to never have consecutive free
chunks. If that ever happens we failed to merge them. That means a free
chunk must always be surrounded by used chunks.

It is a pain to extend valid_chunk() with new rules as it is.
So a VALIDATE() macro is introduced to make things easier to work with.
It also allows for isolating each test, possibly making VALIDATE() into
__ASSERT() to determine exactly which test is tripping when debugging.

Finally, because of that new validation rule, sys_heap_validate() must
be modified so not to use valid_chunk() while it is flipping all the
"used" flags. So let's run valid_chunk() up front before alterating
chunk headers.

Now sys_heap_validate() has become justifiably more expensive and a few
emulated targets are about to bust the tests/lib/heap test timeout. So
bump the timeout as well.

a3a5c72d9b tests: filter out nsim as it's slow
nsim is slow, if the MEMSZ is too targe, the test will
run a long time and make sanitycheck timeout.

There are two possible fixes to pass the sanitycheck test
  * filter out nsim, not to block the sanitcheck test
  * use a small MEMSZ for nsim to reduce the execution time.

Considering there are potential improvements for nsim (because
some qemu targets can pass), we use the 1st fix to pass the
sanitycheck temporarily.

2eb897ed1c cmake: removing DTS_ROOTS in test samples as they serves no purpose
This commit is a cleanup in two test samples.

In both samples, the following line of code were found:

    set(DTS_ROOTS ${CMAKE_CURRENT_LIST_DIR})

Firstly, it is not needed to set `DTS_ROOT` in samples, as the sample
folder is always added to `DTS_ROOT`.
Secondly, the variable is named `DTS_ROOT`, but the samples used a
misspelled version `DTS_ROOTS`, which means that variable has never
had any effect.

1e52b1123e tests/lib/heap_align: improve test
Many issues:

- heapmem[] is of type uint64_t meaning that it contains HEAP_SZ * 16
  bytes but the heap is initialized with only 1/16 of that, making
  this test's memory footprint way too large.

- The test to ensure the heap is empty uses an allocation size of
  (heap_end - heap_start - 8) which is wrong as heap_end and heap_start
  are uint64_t pointer types and therefore their difference will be 8x
  smaller than intended. Furthermore, the 8 here is unnessary as the
  chunk header size is already included in the location of heap_start.

- The heap start address misalignment bare no purpose as the misaligned
  start of the free heap is already controlled by the variable prefix
  allocation size.

- Alignment and sizes should rather be expressed in terms of size_t
  rather than uintptr_t.

Fix those issues, and add a few more test angles:

- Make the prefix allocation itterate across the entire alignment range
  to exercize all possible misalignments.

- Vary the aligned allocation size to better exercize the pre-alignment
  allocation and suffix handling.

- Double the aligned allocation to add more variability in the heap
  structure.

- Test the testing of emptiness by making sure that no more allocations
  are possible when we think we allocated it all.

af4ce4a166 tests/lib: Add heap_align test
Test of the sys_heap_aligned_alloc() API.  This is separate from the
existing heap test because aligned_alloc() requires a kconfig to
enable it that can change the heap block header format and will impact
code coverage of the "small" block variant.

It's a fairly simple whitebox test that instantiates a heap and then
enumerates all possible alignments within it, with and without
pre-allocated data, to verify that the resulting memory is correctly
aligned and the heap stays consistent.

e4a761cffe devicetree: add migration guide documentation and tests
Add test cases that verify various bits and pieces of the legacy
devicetree macros match the new APIs.

Writing these test cases without giving rise to deprecated macro
warnings which might break people's CI if they build with -Werror
requires turning off the __WARN() generation in
devicetree_legacy_unfixed.h. The entire file is deprecated at this
point and must be explicitly enabled with an opt-in Kconfig option, so
there isn't any harm in doing this.

Nevertheless, take a minimally invasive approach to avoiding __WARN()
generation in gen_legacy_defines.py, to avoid the possibility of
breakage. This code is basically frozen anyway, so hacks like this
won't cause maintainability problems since it isn't being actively
maintained.

Use the new tests as fodder for a migration guide from the old API in
the documentation.

6e8775ff84 devicetree: remove DT_HAS_NODE_STATUS_OKAY
Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:

- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
  for macros which are equivalent to
  DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name

Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.

This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

7e0eed9235 devicetree: allow access to all nodes
Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.

Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.

To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:

- emit macros for all existing nodes in gen_defines.py, regardless
  of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter

Make drivers multi-instance wherever possible using DT_INST_FOREACH.
This allows removing DT_HAS_DRV_INST in favor of making drivers just
do the right thing regardless of how many instances there are.

There are a few exceptions:

- SoC drivers which use CMake input files (like i2c_dw.c) or otherwise
  would require more time to convert than I have at the moment. For the
  sake of expediency, just inline the DT_HAS_DRV_INST expansion for
  now in these cases.

- SoC drivers which are explicitly single-instance (like the nRF SAADC
  driver). Again for the sake of expediency, drop a BUILD_ASSERT in
  those cases to make sure the assumption that all supported SoCs have
  at most one available instance is valid, failing fast otherwise.

0e6ede8929 kconfig: Rename CONFIG_FLOAT to CONFIG_FPU
This commit renames the Kconfig `FLOAT` symbol to `FPU`, since this
symbol only indicates that the hardware Floating Point Unit (FPU) is
used and does not imply and/or indicate the general availability of
toolchain-level floating point support (i.e. this symbol is not
selected when building for an FPU-less platform that supports floating
point operations through the toolchain-provided software floating point
library).

Moreover, given that the symbol that indicates the availability of FPU
is named `CPU_HAS_FPU`, it only makes sense to use "FPU" in the name of
the symbol that enables the FPU.

30a5aefb54 tests: lib: cmsis_dsp: Restrict testing platforms
In order to reduce CI overhead, this commit restricts the CMSIS-DSP
tests to only run on the following ARM platforms:

* `frdm_k64f`: Cortex-M4 (to be replaced by `qemu_cortex_m4`)
* `sam_e70_xplained`: Cortex-M7
* `mps2_an521`: Cortex-M33

The following platforms should be added to the platform whitelist in
the future when adequate support is available:

* `qemu_cortex_m4`: Replace `frdm_k64f` when available
* `qemu_cortex_r5`: Add when Cortex-R VFP support is available
* `qemu_cortex_a53`: Add when AArch64 VFP support is available
(and other VFP-equipped ARM testing platforms added in the future)

a3859a3873 tests: lib: cmsis_dsp: Add 'filtering' test application
This commit adds the test application for the CMSIS-DSP 'filtering'
functions.

This test application is loosely based on the C++ test suite included
in the upstream CMSIS-DSP distribution.
