Move
+sampling time setting into ADC init stucture (keep setting into ADC
+channel init stucture with comments of obsolete setting).

+DAC_FLAG_DMAUDR2.
HAL DMA
Correct __HAL_DMA_GET_IT_SOURCE brief comments.

HAL IRDA
HAL_IRDA_DMAStop(): update comments regarding deletion of LOCK/UNLOCK mechanism.

Add missing IDLE flag management.
Align SMARTCARD_Last_Bit defines.
HAL SPI
Fix issue related to missing reset of the Dma Tx callback inside the function HAL_SPI_TransmitReceive_DMA(). In
+that case only RX callback are used and the call of TX callback can
+close the communication before the end of the RX processing.
SPI_2linesRxISR_8BIT():
+correct issue on RX 2lines with DataSize8bit, even buffer size and CRC
+8bit (SPI_RXFIFO_THRESHOLD is not set).

stm32f0xx_hal_rtc_ex.c:
+remove HAL_RTCEx_Tamper3EventCallback()
+API for STM32F070xB

+;* Description : STM32F042x4/STM32F042x6 devices vector table for MDK-ARM toolchain.
+;* This module performs:
+;* - Set the initial SP
+;* - Set the initial PC == Reset_Handler
+;* - Set the vector table entries with the exceptions ISR address
+;* - Branches to __main in the C library (which eventually
+;* calls main()).
+;* After Reset the CortexM0 processor is in Thread mode,
+;* priority is Privileged, and the Stack is set to Main.
+;* <<< Use Configuration Wizard in Context Menu >>>

+ * @author MCD Application Team
+ * @version V2.2.2
+ * @date 26-June-2015
+ * @brief CMSIS Cortex-M0 Device Peripheral Access Layer System Source File.
+ *
+ * 1. This file provides two functions and one global variable to be called from
+ * user application:
+ * - SystemInit(): This function is called at startup just after reset and
+ * before branch to main program. This call is made inside
+ * the "startup_stm32f0xx.s" file.
+ *
+ * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+ * by the user application to setup the SysTick
+ * timer or configure other parameters.
+ *
+ * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+ * be called whenever the core clock is changed
+ * during program execution.
+ *
+ * 2. After each device reset the HSI (8 MHz) is used as system clock source.
+ * Then SystemInit() function is called, in "startup_stm32f0xx.s" file, to
+ * configure the system clock before to branch to main program.
+ *
+ * 3. This file configures the system clock as follows:
+ *=============================================================================
+ * System clock source | 1- PLL_HSE_EXTC | 3- PLL_HSI
+ * | (external 8 MHz clock) | (internal 48 MHz)
+ * | 2- PLL_HSE_XTAL |
+ * | (external 8 MHz xtal) |
+ *-----------------------------------------------------------------------------
+ * SYSCLK(MHz) | 48 | 48
+ *-----------------------------------------------------------------------------
+ * AHBCLK (MHz) | 48 | 48
+ *-----------------------------------------------------------------------------
+ * APB1CLK (MHz) | 48 | 48
+ *-----------------------------------------------------------------------------
+ * USB capable (48 MHz precise clock) | YES | YES
+ *=============================================================================
