Some USART2 #define seems to be missing from stm32g030xx.h, stm32g031xx.h, stm32g041xx.h

stm32g030xx.h, stm32g031xx.h, stm32g041xx.h:

these #define seems to be missing/removed from aforementioned files:

#define RCC_CCIPR_USART2SEL_Pos     (2U)

#define RCC_CCIPR_USART2SEL_Msk     (0x3UL << RCC_CCIPR_USART2SEL_Pos)   /*!< 0x0000000C */

#define RCC_CCIPR_USART2SEL       RCC_CCIPR_USART2SEL_Msk

#define RCC_CCIPR_USART2SEL_0      (0x1UL << RCC_CCIPR_USART2SEL_Pos)   /*!< 0x00000004 */

#define RCC_CCIPR_USART2SEL_1      (0x2UL << RCC_CCIPR_USART2SEL_Pos)   /*!< 0x00000008 */

Clock selection for USART2 isn't available on these devices per the RMs.

Hello @Community member​ and welcome to the Community :)

Thanks for your reported issue.

I will check this internally with the latest release of STM32CubeG0 package, and I will take the necessary action.

You are right @TDK​.

I checked the spec and I confirm that the USART2 is only applies to STM32G070xx and to STM32G0B0xx devices.

So, the HAL define is correct, and there is no missing.
