boards: arm: Modify BMD-345-EVAL support

Browse source 
Modify support for u-blox BMD-345-EVAL which uses the nRF52840
and a Skyworks RFX2411 FEM.

These edits follow the naming cnoventions that is used
with the other u-blox EVKs recently added, or in progress

This board is similar to the nRF52840dk_nrf52840 with the
addition of a FEM. Four Arduino GPIO pins have been
reassigned to the PA_LNA control pins.

u-blox would prefer to use this naming convention to match
other BMD-3xx-EVAL and EVK-NINA-Bx boards recently submitted.

Tested with blinky, button, and Bluetooth peripheral_hr
Checking dts files
Updated CODEOWNERS to rename bmd_345_eval to ubx_bmd345eval_nrf52840
Added CMakeLists.txt, updated board.c

Hardware
********
BMD-345 on the BMD-345-EVAL board has an internal high frequency oscillator
at 32MHz and external slow frequency oscillator at 32.768kHz.
Front End Module
================
BMD-345 utilizes the skyworks RFX2411 front end module (FEM) also known as PA/LNA.
The FEM provides higher output power and better sensitivity.

Programming and Debugging
*************************
Applications for the ``bmd_345_eval`` board configuration can be
built and flashed in the usual way (see :ref:`build_an_application`
and :ref:`application_run` for more details).
Flashing
========
Follow the instructions in the :ref:`nordic_segger` page to install
and configure all the necessary software. Further information can be
found in :ref:`nordic_segger_flashing`. Then build and flash
applications as usual (see :ref:`build_an_application` and
:ref:`application_run` for more details).
Here is an example for the :ref:`hello_world` application.
First, run your favorite terminal program to listen for output.
.. code-block:: console
$ minicom -D <tty_device> -b 115200
Replace :code:`<tty_device>` with the port where the board nRF52840 DK
can be found. For example, under Linux, :code:`/dev/ttyACM0`.
Then build and flash the application in the usual way.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: bmd_345_eval
:goals: build flash
Debugging
=========
Refer to the :ref:`nordic_segger` page to learn about debugging Nordic boards with a
Segger IC.
Testing the LEDs and buttons in the BMD 345 EVAL
************************************************
There are 2 samples that allow you to test that the buttons (switches) and LEDs on
the board are working properly with Zephyr:
.. code-block:: console
samples/basic/blinky
samples/basic/button
You can build and flash the examples to make sure Zephyr is running correctly on
your board. The button and LED definitions can be found in
:zephyr_file:`boards/arm/bmd_345_eval/bmd_345_eval.dts`.
Using UART1
***********
The following approach can be used when an application needs to use
more than one UART for connecting peripheral devices:
1. Add devicetree overlay file to the main directory of your application:
.. code-block:: console
$ cat bmd_345_eval.overlay
&uart1 {
compatible = "nordic,nrf-uarte";
current-speed = <115200>;
status = "okay";
tx-pin = <14>;
rx-pin = <16>;
};
In the overlay file above, pin P0.16 is used for RX and P0.14 is used for TX
2. Use the UART1 as ``device_get_binding(DT_LABEL(DT_NODELABEL(uart1)))``
See :ref:`set-devicetree-overlays` for further details.
Selecting the pins
==================
To select the pin numbers for tx-pin and rx-pin:
.. code-block:: console
tx-pin = <pin_no>
Open the `nRF52840 Product Specification`_, chapter 7 'Hardware and Layout'.
In the table 7.1.1 'aQFN73 ball assignments' select the pins marked
'General purpose I/O'. Note that pins marked as 'low frequency I/O only' can only be used
in under-10KHz applications. They are not suitable for 115200 speed of UART.
Translate the 'Pin' into number for devicetree by using the following formula::
pin_no = b\*32 + a
where ``a`` and ``b`` are from the Pin value in the table (Pb.a).
For example, for P0.1, ``pin_no = 1`` and for P1.0, ``pin_no = 32``.

More information about the BMD-345-EVAL and BMD-345 module can be
found at the `u-blox website`_.
Hardware
********
The BMD-345 on the BMD-345-EVAL contains an internal high-frequency
oscillator at 32MHz. There is also a low frequency (slow)
oscillator of 32.768kHz. The BMD-345 does not include the slow
crystal; however, the BMD-345-EVAL does.
.. note::
When targeting a custom design without a slow crystal, be sure
to modify code to utilize the internal RC oscillator for the
slow clock.

BMD-345 utilizes the Skyworks RFX2411 front end module (FEM).
The FEM provides higher output power and better sensitivity.

Programming and Debugging
*************************
Applications for the BMD-345-EVAL board
configurations can be built and flashed in the usual way
(see :ref:`build_an_application` and :ref:`application_run`
for more details); however, the standard debugging targets
are not currently available.
Flashing
========
Follow the instructions in the :ref:`nordic_segger` page to install
and configure all the necessary software. Further information can be
found in :ref:`nordic_segger_flashing`. Then build and flash
applications as usual (see :ref:`build_an_application` and
:ref:`application_run` for more details).
Here is an example for the :ref:`hello_world` application.
First, run your favorite terminal program to listen for output.
.. code-block:: console
$ minicom -D <tty_device> -b 115200
Replace :code:`<tty_device>` with the port where the BMD-345-EVAL
can be found. For example, under Linux, :code:`/dev/ttyACM0`.
Then build and flash the application in the usual way.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: ubx_bmd345eval_nrf52840
:goals: build flash
Debugging
=========
Refer to the :ref:`nordic_segger` page to learn about debugging
u-blox boards with a Segger J-LINK-OB IC.
Testing the LEDs and buttons in the BMD-345-EVAL
*****************************************************************
There are 2 samples that allow you to test that the buttons
(switches) and LEDs on the board are working properly with Zephyr:
.. code-block:: console
samples/basic/blinky
samples/basic/button
You can build and flash the examples to make sure Zephyr is running
correctly on your board. The button and LED definitions can be found
in
:zephyr_file:`boards/arm/ubx_bmd340eval_nrf52840/ubx_bmd345eval_nrf52840.dts`.
Using UART1
***********
The following approach can be used when an application needs to use
more than one UART for connecting peripheral devices:
1. Add device tree overlay file to the main directory of your
application:
.. code-block:: console
$ cat ubx_bmd345eval_nrf52840.overlay
&uart1 {
compatible = "nordic,nrf-uarte";
current-speed = <115200>;
status = "okay";
tx-pin = <14>;
rx-pin = <16>;
};
In the overlay file above, pin P0.16 is used for RX and P0.14 is
used for TX
2. Use the UART1 as ``device_get_binding("UART_1")``
Overlay file naming
===================
The file has to be named ``<board>.overlay`` and placed in the app
main directory to be picked up automatically by the device tree
compiler.
Selecting the pins
==================
To select the pin numbers for tx-pin and rx-pin:
.. code-block:: console
tx-pin = <pin_no>
Open the data sheet for the BMD-345 at the `u-blox website`_, Section 2
'Pin definition'. In the table 3 select the pins marked 'GPIO'.
Note that pins marked as 'Standard drive, low frequency I/O only
(<10 kH' can only be used in under-10KHz applications.
They are not suitable for 115200 speed of UART.
Translate 'Pin' into number for Device tree by using the following
formula::
pin_no = b\*32 + a
where ``a`` and ``b`` are from the Pin value in the table (Pb.a).
For example, for P0.1, ``pin_no = 1`` and for P1.0, ``pin_no = 32``.
.. note:
Pins are defined according to the "nRF52" pin number, not the module
pad number.
