| H A D | stm32-usart.h | diff 7f28bcea824e4fb192214c6121161053efe738a8 Tue Aug 08 11:19:04 CDT 2023 Valentin Caron <valentin.caron@foss.st.com> serial: stm32: group dma pause/resume error handling into single function
Create new function "stm32_usart_dma_pause_resume" that called dmaengine_
pause/resume and in case of error, terminate dma transaction.
Two other functions are created to facilitate the use of stm32_usart_dma
_pause_resume : stm32_usart_tx_dma_pause, stm32_usart_tx_dma_resume.
Equivalent functions for rx will be added in future patch.
