   13  * @page c_ips Input Power Supply Monitoring API
   14  *
   15  * @ref le_ips_interface.h "API Reference"
   16  *
   17  * <HR>
   18  *
   19  * The IPS API is used to get monitoring information related to the platform power supply and set
   20  * warning and critical thresholds.
   21  *
   22  * @section le_ips_binding IPC interfaces binding
   23  *
   24  * All the functions of this API are provided by the @b modemService.
   25  *
   26  * Here's a code sample binding to modem services:
   27  * @verbatim
   28    bindings:
   29    {
   30       clientExe.clientComponent.le_ips -> modemService.le_ips
   31    }
   32    @endverbatim
   33  *
   34  * @section le_ips_powerMonitoring Input power supply monitoring
   35  *
   36  * This functionality allows to retrieve data related to the platform power supply, so that
   37  * the application can use the information to diagnose why the modem isn't fully functioning.
   38  *
   39  * The application can retrieve the following power supply information:
   40  * - le_ips_GetInputVoltage() API gives the Platform voltage input.
   41  * - le_ips_GetPowerSource() API gives the power source used by the Platform:
   42  *     - @ref LE_IPS_POWER_SOURCE_EXTERNAL for an external power source
   43  *     - @ref LE_IPS_POWER_SOURCE_BATTERY for a battery.
   44  * - le_ips_GetBatteryLevel() API gives the Platform battery level.
   45  *
   46  * In case the device is powered by an external battery monitored by an application, this
   47  * application can set the battery level with the le_ips_SetBatteryLevel() API. This value will
   48  * then be used when the battery level is requested through the le_ips_GetBatteryLevel() API.
   49  *
   50  * @note The value set by le_ips_SetBatteryLevel() will be reported by le_ips_GetBatteryLevel()
   51  * until Legato is restarted.
   52  *
   53  * @section le_ips_voltageThresholds Platform input voltage thresholds
   54  *
   55  * @warning When a critical event occurs, some platform may automatically switch off.
   56  *
   57  * @warning On some platforms, the thresholds parameters are persistent and a platform reboot is
   58  * required for thresholds change takes effect.
   59  *
   60  * Four thresholds are set to decide the state: the @e critical, @e warning, @e normal and
   61  * <em>high critical</em> platform input voltage thresholds.
   62  *
   63  * if the platform input voltage decreases below the:
   64  *  - "High critical threshold - 1 " but still higher than "Warning threshold",
   65  * @c LE_IPS_VOLTAGE_NORMAL event occurs.
   66  *  - "Warning threshold" but still higher than "Critical threshold",
   67  * @c LE_IPS_VOLTAGE_WARNING event occurs.
   68  *  - "Critical threshold", a @c LE_IPS_VOLTAGE_CRITICAL event occurs.
   69  *
   70  * if the platform input voltage goes up and it reaches the:
   71  *  - "Normal threshold", a @c LE_IPS_VOLTAGE_NORMAL event occurs.
   72  *  - "High critical thresholds", a @c LE_IPS_HI_VOLTAGE_CRITICAL event occurs.
   73  *
   74  * @note The threshold values range is platform dependent.
   75  *
   76  * - le_ips_SetVoltageThresholds() API allows the application to set platform input voltage
   77  *  thresholds.
   78  * - le_ips_GetVoltageThresholds() API allows the application to get platform input voltage
   79  * thresholds.
   80  * - le_ips_AddThresholdEventHandler() API adds a handler to notify when the platform input voltage
   81  *  threshold is reached.
   82  * - le_ips_RemoveThresholdEventHandler() API removes the platform input voltage handler.
