This is a follow-up to commit 25d7a09aa5.
The arduino_serial/uart1 node should not be enabled by default because
even if an application does not use it, the default CONFIG_SERIAL=y
setting causes that it is anyway initialized, so the UARTE peripheral
acquires its assigned pins (and they cannot be used in other way) and
its enabled receiver causes increased current consumption (by ~500 uA)
when the CPU is sleeping. This affects e.g. the boards/nrf/system_off
sample.
Applications that actually need to use this UART or shields that use
the arduino_serial node should enable the node explicitly.
Keep this node disabled by default for the nrf52840dk_nrf52840 board
and also for boards whose definitions are mostly copies of the above:
nrf52833dk_nrf52833 and nrf21540dk_nrf52840.
Update also accordingly a few overlay files in tests/ that were
disabling this node because of the pins it undesirably acquired.

This test uses the arduino_i2c and arduino_serial DT nodes, so it
should enable them explicitly, not assume they will be enabled by
default for a given board.

Add kscan pins gpio driver for KSI[7:0], KSO[15:0] pins that
they can be configured to gpio mode. These pins registers address,
bit fields and function are different from GPIO group, so I create
a new compatible driver for these pins.

This commit updates all deprecated `CONFIG_LIB_CPLUSPLUS` usages to:
* check if the Zephyr minimal C++ library is enabled using
`CONFIG_MINIMAL_LIBCPP` instead of relying on the
`CONFIG_LIB_CPLUSPLUS`-based inference.
* select `CONFIG_REQUIRES_FULL_LIBCPP` when there exists a component-
level C++ standard library dependency. This allows a component to
declare C++ standard library dependency without designating a
specific libray implementation.
* select the correct type of C++ standard library implementation to use
through one of the `CONFIG_LIBCPP_IMPLEMENTATION` choices.

This commit reworks the C++ standard library configurations such that:
* the separation between the Zephyr minimal C++ library and the fully
featured C++ standard libraries, such as GNU libstdc++, is clear.
This is done by deprecating the Kconfig `CONFIG_LIB_CPLUSPLUS`
symbol, which implies that the minimal C++ library is selected when
set to `n`, and introducing the `CONFIG_MINIMAL_LIBCPP` symbol.
* the type of the selected C++ standard library is clear. This is done
by introducing a Kconfig choice, `LIBCPP_IMPLEMENTATION`, for the C++
standard library type and providing the choice symbols for each
library type supported, such as `CONFIG_MINIMAL_LIBCPP` and
`CONFIG_GLIBCXX_LIBCPP`.

This commit updates all in-tree code to use `CONFIG_CPP_RTTI` instead
of `CONFIG_RTTI`, which is now deprecated.
Signed-off-by: Stephanos Ioannidis <stephanos.ioannidis@nordicsemi.no>
The Kconfig `CONFIG_RTTI` symbol enables the C++ Run-Time Type
Information (RTTI) support and is a feature of the standard C++
library; therefore, it should be prefixed with `CPP_` as with the rest
of the C++-specific symbols.
This commit renames the Kconfig `CONFIG_RTTI` symbol to
`CONFIG_CPP_RTTI` in order to better align with the other existing C++
Kconfig symbols, and deprecates the old `CONFIG_RTTI` symbol.

instead of `CONFIG_EXCEPTIONS`, which is now deprecated.
Signed-off-by: Stephanos Ioannidis <stephanos.ioannidis@nordicsemi.no>
`CONFIG_EXCEPTIONS` is ambiguous in that the word "exception" may be
used to refer to many different types of exceptions, from the hardware
generated faults and interrupts (aka. exceptions) to the C++
exceptions.
This commit renames the Kconfig `CONFIG_EXCEPTIONS` symbol to
`CONFIG_CPP_EXCEPTIONS` in order to clarify that the symbol refers to
the C++ exceptions and eliminate any ambiguity, and deprecates the old
`CONFIG_EXCEPTIONS` symbol.

Signed-off-by: Stephanos Ioannidis <stephanos.ioannidis@nordicsemi.no>
There is no reason for the top-level C++ Kconfig symbol to be called
`CPLUSPLUS` when the convention used throughout the Zephyr codebase is
to use "cpp" to refer to C++ and the rest of the C++-related Kconfig
symbols are prefixed with `CPP_`.
This commit renames the Kconfig `CPLUSPLUS` symbol to `CPP` in order to
better align with the de-facto standard naming convention used throughout
the Zephyr codebase, and deprecates the old `CPLUSPLUS` symbol.

This commit relocates the "C++ minimal library" components, that
implement a very limited subset of the standard C++ library, to a
dedicated directory, `lib/cpp/minimal`, in order to provide a clear
separation among the different C++ library components.
After this refactoring, the top `lib/cpp` directory should only contain
the sub-directories for each C++ library (i.e. `abi`, `minimal`). In
the future, a C++ library-specific shim layer implementation may be
added as sub-directories under `lib/cpp` as well (e.g. `libstdc++`
sub-directory containing the shim layer implementation for the GCC
libstdc++ library) -- this is similar to how the libc directories are
structured under `lib/libc`.

This commit relocates the "C++ ABI library" components such as
global constructor/destructor and initialiser handlers to a dedicated
directory, `lib/cpp/abi`, in order to provide a clear separation
between the C++ ABI/runtime library and the standard C++ library
components.
Note that the Zephyr C++ ABI library currently implements the GNU/GCC
C++ ABI, which is the de-facto standard ABI used by many compilers
including Clang -- it may be necessary to sub-divide the `lib/cpp/abi`
into `lib/cpp/abi/gnu` and `lib/cpp/abi/someotherabi` in the future
when adding the support for a C++ compiler that expects an ABI vastly
different from the GNU C++ ABI.
