Gerard Marull-Paretas 79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

DPS310 Temperature and Pressure Sensor
######################################

Overview
********

This sample application periodically reads temperature and pressure data from
the first available device that implements SENSOR_CHAN_AMBIENT_TEMP and
SENSOR_CHAN_PRESS. This sample checks the sensor in polling mode (without
interrupt trigger).

Building and Running
********************

This sample application uses an DPS310 sensor connected to a board via I2C.
Connect the sensor pins according to the connection diagram given in the
`dps310 datasheet`_ at page 18 figure 7.

Build and flash this sample (for example, for the nrf52840dk_nrf52840 board)
using these commands:

.. zephyr-app-commands::
   :zephyr-app: samples/sensors/dps310
   :board: nrf52840dk_nrf52840
   :goals: flash
   :compact:

Sample Output
=============
To check output of this sample, any serial console program can be used.
This example uses ``picocom`` on the serial port ``/dev/ttyUSB0``:

.. code-block:: console

        $ sudo picocom -D /dev/ttyUSB0

.. code-block:: console

        temp: 23.774363; press: 97.354728
        temp: 23.777492; press: 97.353904
        temp: 23.784646; press: 97.354064
