- * Name: stm32_pmstop
- *
- * Description:
- *   Enter STOP mode. 
- *
- * Input Parameters:
- *   lpds - true: To further reduce power consumption in Stop mode, put the
- *          internal voltage regulator in low-power mode using the LPDS bit
- *          of the Power control register (PWR_CR).
- *
- * Returned Value:
- *   Zero means that the STOP was successfully entered and the system has
- *   been re-awakened.  The internal volatage regulator is back to its
- *   original state.  Otherwise, STOP mode did not occur and a negated
- *   errno value is returned to indicate the cause of the failure.
