7bc6bc8681 dts: bindings: test: device labels are now optional
All in tree device drivers use some form of DEVICE_DT_GET
so we no longer need to require label properties.

9964414655 include/devicetree.h: Add DT_STRING_TOKEN_OR macro
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.

The vnd,gpio-device compatible is now used by the test GPIO driver
(CONFIG_GPIO_TEST) introduced in #41387. This means that we can't define
new devices with this compatible when CONFIG_GPIO=y.

1976f33e87 drivers: mbox: Introduce MBOX driver class
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previous (and outdated) IPM API.

42105ed882 dts: Add support for specifier-space property.
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.

9c229a417c devicetree: add DT_FOREACH_PROP_ELEM(node_id, prop, fn)
It can be convenient to "iterate" over the elements of a property, in
the same way it is convenient to "iterate" over enabled instances.

Add a new macro for doing this, along with a DT_INST_FOREACH_PROP_ELEM
variant.

This is likely to be more convenient than UTIL_LISTIFY or FOR_EACH in
some situations because:

- it handles inputs of any length
- compiler error messages will be shorter and more self-contained
- it is easier to use with phandle-array type properties, which
  require more complicated macro boilerplate when used with
  util_macro.h APIs

b2cc526061 tests: dts: test child bindings with compatibles
Make sure that child bindings with their own compatibles are treated
as first-class bindings. Do this by making sure that nodes whose
bindings are defined via 'child-binding:' are picked up as bus nodes,
instead of a parent bus node of the same type.

ad49bcf492 devicetree: add DT_INST_BUS(node_id)
This returns the node identifier for a node's bus. For example, for a
device on an I2C bus, it would return a node identifier for the I2C
bus controller.

We already have a DT_BUS() and DT_INST_BUS_LABEL(), but there hasn't
been a request or need for DT_INST_BUS() up until now, so it didn't
exist yet.

38ede5aded dts: handle unspecified phandle-array elements
The DTS language permits zeroing out phandles in a phandle array to
say "there's nothing at this index", and dtlib manages that correctly,
but edtlib and gen_defines.py aren't equipped to do so.

Fix this by allowing None elements in the lists of ControllerAndData
values returned by edtlib for such properties.

Handle that in gen_defines.py by setting the generated
DT_N_<node>_P_<prop>_IDX_<i>_EXISTS macro to 0 in such cases.

The DT_N_<node>_P_<prop>_LEN macro still accounts for the entire
length of the phandle-array; it's just that some indexes may be
missing data.

305379e944 devicetree: add first round of dependency ordinal info
Add the first API functions that directly deal with node dependency
ordinals as determined by edtlib:

- DT_DEP_ORD(node_id): node_id's ordinal
- DT_REQUIRES_DEP_ORDS(node_id): list of dep ordinals for node_id's
  direct dependencies
- DT_SUPPORTS_DEP_ORDS(node_id): list of dep ordinals for nodes
  depending directly on node_id
- DT_INST_ equivalents

This is not meant to be an exhaustive set of macros related to
dependency ordinals; rather, it's a starting out point meant to enable
initial struct device dependency tracking work. We can add more if
needed.
