Armando Visconti 87d6c50e47 sensors: Add separation between ambient and die temperature
Some device include a temperature sensor, usually used as a
companion for helping in drift compensation, that measure the
die temperature. This temperature IS NOT related to the the
ambient temperature, hence a clean separation between the two
is required.

This commit introduces a clean separation between the two
types of temperature leaving the old deprecated definition
still there.

The list of current drivers that read the die (and not the ambient)
temperature is the following:

 - adxl362
 - bma280
 - bmg160
 - bmi160
 - fxos8700
 - lis3mdl
 - lsm6ds0
 - lsm6dsl
 - lsm9ds0
 - mpu6050

FXOS8700 Accelerometer/Magnetometer Sensor
##########################################

Overview
********

A sensor application that demonstrates how to use the fxos8700 data ready
interrupt to read accelerometer/magnetometer data synchronously.

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

This project outputs sensor data to the console. It requires an fxos8700
sensor, which is present on the :ref:`frdm_k64f`, :ref:`frdm_kw41z`, and
:ref:`hexiwear_k64` boards.  It does not work on QEMU.
