Andrzej Głąbek 97b07b943a drivers/serial/Kconfig.nrfx: Choose driver type basing on DT compatible Remove prompts from Kconfig options `UART_x_NRF_UART` that select the type of nrfx driver (for UART or UARTE peripheral) to be used for a given instance. This prevents the options from being modified from configuration files. Instead, make one of these options selected by default according to the "compatible" property set for the corresponding UART node in devicetree. This eliminates the need of changing both the "compatible" property in devicetree and the Kconfig option selecting the driver type when a user wants to switch between UART and UARTE for a given instance. Since all `UART_x_NRF_UART` options are made "hidden" by this commit, all their occurrences in configuration files are removed.

Generic GSM Modem Sample
########################

Overview
********

The Zephyr GSM modem sample application allows user to have a connection
to GPRS network. The connection to GSM modem is done using
:ref:`PPP (Point-to-Point Protocol) <ppp>`.

The source code of this sample application can be found at:
:zephyr_file:`samples/net/gsm_modem`.

Requirements
************

- GSM modem card. The sample has been tested with SIMCOM SIM808 card. All
  GSM modem cards should work as long as they support **AT+CGDCONT** command.
- Almost any Zephyr enabled board with sufficient resources can be used.
  The sample has been tested with :ref:`reel_board`.

Build and Running
*****************

If you are using an external modem like the SIMCOM card, then connect
the necessary pins like RX and TX from your Zephyr target board to the
modem card. Internal modems, like what is found in :ref:`particle_boron`
board, are not yet supported.

Note that you might need to change the APN name according to your GSM network
configuration.
