Andrzej Głąbek 79cc5a96bd dts: nrf5340: Use dual compatible property for mbox nodes This is a follow-up to commit `cf6a58d3f6`. Restore the "nordic,nrf-ipc" compatible property in mbox nodes for both nRF5340 cores and use it together with the new "nordic,mbox-nrf-ipc" one. This way either the MBOX or the IPM driver can be used for these nodes without further modifications. This eliminates the need to use overlays in quite a few cases, so remove all those no longer needed ones (which are also a bit confusing now as they refer to no longer existing ipc@2a000 and ipc@41012000 nodes). Restore also the ipc node label removed in the commit mentioned above, as the label is used in validation of base addresses of nRF DT nodes.

RPMsg Service sample Application
################################

Overview
********

RPMsg Service is an abstraction created over OpenAMP that makes initialization
and endpoints creation process easier.
This application demonstrates how to use RPMsg Service in Zephyr. It is designed
to demonstrate how to integrate RPMsg Service with Zephyr both from a build
perspective and code.

Building the application for nrf5340dk_nrf5340_cpuapp
*****************************************************

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/rpmsg_service
   :board: nrf5340dk_nrf5340_cpuapp

Building the application for mps2_an521
***************************************

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/rpmsg_service
   :board: mps2_an521

Building the application for v2m_musca_b1
*****************************************

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/rpmsg_service
   :board: v2m_musca_b1

Open a serial terminal (minicom, putty, etc.) and connect the board with the
following settings:

- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1

Reset the board and the following message will appear on the corresponding
serial port, one is master another is remote:

.. code-block:: console

Building the application for bl5340_dvk_cpuapp
**********************************************

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/rpmsg_service
   :board: bl5340_dvk_cpuapp
   :goals: debug

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/rpmsg_service
   :board: bl5340_dvk_cpunet
   :goals: debug

Open a serial terminal (for example Minicom or PuTTY) and connect to the board
with the following settings on both serial ports:

- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1

When you reset the development kit after having flashed both the application
and network core images, the following messages (one for master and one for
remote) will appear on the corresponding serial ports:

.. code-block:: console
