STM32 DMAv2 driver.
|
|
|
|
Driver capability:
|
|
|
|
- The driver supports the STM32 enhanced DMA controller found on F2, F4 and
|
|
F7 sub-families.
|
|
- Support for automatic the channel selection.
|
|
- Support for cache flushing and invalidation.
|
|
|
|
The file registry must export:
|
|
|
|
STM32_ADVANCED_DMA - TRUE not used by the DMA drivers but other
|
|
drivers use it to enable checks on DMA
|
|
channels. Probably will be removed in the
|
|
future.
|
|
STM32_HAS_DMAx - Support for DMA unit "x" (1..2).
|
|
STM32_DMAx_CHn_HANDLER - Vector name for channel "n" (0..7).
|
|
STM32_DMAn_CHx_NUMBER - Vector number for channel "n" (0..7).
|
|
STM32_DMA_CACHE_HANDLING - TRUE if the device requires explicit cache
|
|
handling on DMA buffers. |
