- Unify DMA/BDMA/GPDMA descriptors in drv_dma (common fields + per-type union)
- Support BDMA in SPI driver with h7 dma/spi config header updates
- Add SPI6 TX/RX BDMA Kconfig options for H7
fix[STM32][SPI]: preload receive-only dummy buffer2026-05-20T02:42:56Zwdfk-prog1425075683@qq.com2026-05-18T08:02:59Zurn:sha1:3fa50a4b33869050ca8f17e5162b397fddf3e5bf
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
feat[STM32][SPI]: add interrupt transfer scaffolding for spi driver2026-05-20T02:42:56Zwdfk-prog1425075683@qq.com2026-05-06T13:02:37Zurn:sha1:415f924c5fb08b03a9b3a5a5ef63a1a7705378b3
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
feat[STM32][SPI]: refine dma config hierarchy for hard spi2026-05-20T02:42:56Zwdfk-prog1425075683@qq.com2026-04-15T02:53:21Zurn:sha1:e37e3107f4bb18a06f4b922032345a2e1938f893
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
refactor[STM32][DMA]: add common DMA helper layer for HAL drivers2026-05-06T07:30:39Zwdfk-prog1425075683@qq.com2026-05-05T01:06:22Zurn:sha1:c45f5f926725d521db3a438117688c2011c0bed6
- 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
feat[SPI]: Add SPI device detach function2025-09-25T03:41:58Zwdfk-prog1425075683@qq.com2025-09-25T02:31:19Zurn:sha1:7e5cd483600a5ad66d3d9d3dc761281469bec69e[stm32] split stm32 drivers as normal and nano drivers2023-12-03T13:25:00ZMeco Man920369182@qq.com2023-12-02T17:32:27Zurn:sha1:860094e89366bd6f714728e2e9c3de7517a91720
- move all normal drivers (devices framework drivers) into drivers
folder.
- create nano folder for nano drivers
nano drivers are only for a simply wrap of the HAL function, and
not seek for adopting rt-thread devcies framework.
- provide unified nano console and GPIO drivers.
