Now that device_api attribute is unmodified at runtime, as well as all the other attributes, it is possible to switch all device driver instance to be constant. A coccinelle rule is used for this: @r_const_dev_1 disable optional_qualifier @ @@ -struct device * +const struct device * @r_const_dev_2 disable optional_qualifier @ @@ -struct device * const +const struct device * Fixes #27399 Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com> |

SM351LT: Magnetoresistive Sensor Example
########################################
Overview
********
This sample application periodically polls an SM351LT magnetoresistive sensor
and displays if a magnet near to the sensor, via the console.
Requirements
************
This sample uses the Honeywell SM351LT sensor.
