This macro expands to DT_STRING_TOKEN if property exists, otherwise
falls back to default value.
Helpful when a non-required enum binding doesn't mention a default
value, but a default value makes sense to be set in the code.
Including DT_INST_STRING_TOKEN_OR and test code.

One limitation of the current IPM API is that it is assuming that the
hardware is only exporting one single channel through which the data can
be sent or signalling can happen.
If the hardware supports multiple channels, the IPM device must be
instantiated (possibly in the DT) several times, one for each channel to
be able to send data through multiple channels using the same hw
peripheral. Also in the current IPM API only one callback can be
registered, that means that only one driver is controlling all the
signalling happening on all the channels.
This patch is introducing a new MBOX API that is supporting
multi-channel signalling and data exachange leveraging and extending the
previous (and outdated) IPM API.

Add a set of tests to check the API behavior. The API tests can only run
on a platform that does not have an actual pinctrl driver, e.g.
native_posix. The test itself implements a pinctrl mock driver and
provides the required "pinctrl_soc.h" header with required types/macros.
The implementation is used in the tests to verify the behavior of the
API or Devicetree macros.

Currently all the *-names and *-cells properties are derived from the
name of the base <name>s property. This is a limitation because:
- It forces the base property name to be plural ending in -s
- It doesn't allow the english exception of plural words ending in -es
With this patch we add one additional property 'specifier-space' that
can be used to explicitly specify the base property name.

Make sure that child bindings with their own compatibles are treated
as first-class bindings. Do this by making sure that nodes whose

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.

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>
