Data Structures
struct	UART_DmaFxns
	Driver implementation callbacks. More...
struct	UART_DmaConfig
	UART DMA Configuration, these are filled by SysCfg based on the DMA driver that is selected. More...

Typedefs
typedef void *	UART_DmaHandle
	Handle to the UART DMA Config Object returned by UART_dmaOpen. More...
typedef int32_t(*	UART_dmaOpenFxn) (UART_Handle uartHandle, void *uartDmaArgs)
	Driver implementation to open a specific DMA driver channel - UDMA, EDMA etc. More...
typedef int32_t(*	UART_dmaTransferReadFxn) (UART_Object *obj, const UART_Attrs *attrs, UART_Transaction *transaction)
	Driver implementation to do a DMA read using a specific DMA driver - UDMA, EDMA etc. More...
typedef int32_t(*	UART_dmaTransferWriteFxn) (UART_Object *obj, const UART_Attrs *attrs, UART_Transaction *transaction)
	Driver implementation to do a DMA write using a specific DMA driver - UDMA, EDMA etc. More...
typedef int32_t(*	UART_dmaCloseFxn) (UART_Handle handle)
	Driver implementation to close a specific DMA driver channel - UDMA, EDMA etc. More...
typedef int32_t(*	UART_dmaDisableChannelFxn) (UART_Handle handle, uint32_t isChannelTx)
	Driver implementation to diisable a specific DMA driver channel - UDMA, EDMA etc. More...
