+
+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.
