CSL_edma3HwSetup
Description
This function does the setup for all DMA/QDMA channels by doing the following operations:-
Arguments
hMod Edma module Handle setup Pointer to the setup structure
Return Value CSL_Status
Success - CSL_SOK
Error - CSL_ESYS_BADHANDLE (The handle passed is invalid)
Error - CSL_ESYS_INVPARAMS (The parameter passed is invalid)
Pre Condition
CSL_edma3Init(), CSL_edma3Open() must be called successfully in that order before this API can be invoked
Post Condition
EDMA registers are configured according to the hardware setup parameters
