+STM32 DMAv3 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.
+- The driver supports the STM32 enhanced DMA controller found on H7 sub-family.
- 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_DMAx_CHn_NUMBER - Vector number for channel "n" (0..7).
STM32_DMA_CACHE_HANDLING - TRUE if the device requires explicit cache
handling on DMA buffers.
