Add the missing UART4 RX DMA definitions for STM32H7.
UART4 RX DMA uses DMA1 Stream0 with the UART4 RX DMA request.
The configuration is enabled when BSP_UART4_RX_USING_DMA is selected.

1.Remove unnecessary comments
|
|
|
|
centralize hard I2C per-message route state for DMA, interrupt, and polling paths
make multi-message and no-stop transfers use sequential HAL APIs only
snapshot scheduler and interrupt context once for stable async transfer decisions
reuse the transaction timeout for async wait logging and abort recovery
|
|
snapshot scheduler and interrupt state once per SPI message
reuse the message-level async route decision for all split chunks
disable DMA and interrupt paths consistently when async transfer is unavailable
avoid mixed async and polling policies within one logical SPI transfer
|
|
preload the actual HAL receive buffer with 0xFF for receive-only transfers
rename spi_dma_flag to spi_xfer_flags to match DMA and interrupt flags
clarify SPI async completion and transfer-mode comments
add Doxygen comments for STM32 SPI runtime structures and handlers
|
|
|
|
introduce interrupt transfer route selection and SPI IRQ visibility macros
unify DMA and INT completion handling with timeout-triggered abort recovery
keep short transfers on polling and use DMA or INT only when eligible
refine STM32 SPI init and IRQ registration paths for mixed transfer backends
|
|
refine the stm32 hard spi dma configuration hierarchy with shared feature macros
align dma flag usage with rt-device dma flags and gate dma-only fields and paths
make the dma transfer threshold configurable through BSP_SPI_DMA_TRANS_MIN_LEN
|
|
|
|
enable I2C error irq when async transfer paths are used fall back to polling when scheduler or interrupt context cannot wait for completion complete the wait path on HAL error callback and abort the transfer on async timeout or error allow INT and DMA mode flags to coexist and keep recovery behavior aligned across STM32 I2C IPs
|
|
|
|
- migrate STM32 HAL driver DMA config macros to shared descriptor init helpers
- add overridable DMA priority and NVIC priority fields for board-level configs
- align SPI, UART, I2C, SDIO, and QSPI DMA descriptors across visible STM32 series configs
- simplify per-series DMA config definitions and reduce duplicated field assignments
|
|
- add drv_dma common helpers and stm32_dma_config descriptors for STM32 series
- refactor i2c, spi, usart, qspi, and sdio DMA setup and deinit paths to reuse the common layer
- unify DMA IRQ enable, rollback handling, and const board-level DMA configuration usage

calculation
|
|
add a control command to register a per-device uart error callback
invoke the callback from the HAL uart error hook and clear it before close
return -RT_ENOSYS when dma mode is requested without dma support
propagate the set-int fallback result in optmode setup to keep control return values explicit

during shift pending
Use the generic SecondFraction/SubSeconds formula when SSR/PRER are available.
If SHPF is present and a shift is pending, keep tv_usec at 0.
Platforms without SSR/PRER (e.g. F1) default to 0.

overruns
- Add CAN_ISR_DRAIN_LIMIT (default 3) to cap ISR work
- Drain multiple frames per RX0/RX1 interrupt to reduce FIFO FULL/OVERRUN
