CSL_edma3GetHwSetup
Description
The function gets the hardware setup for all DMA/QDMA Channels.
Arguments
hMod EDMA Handle setup Setup structure which is populated by this API.
Return Value
Success - CSL_SOK
Error - CSL_ESYS_BADHANDLE (The handle passed is invalid)
Error - CSL_ESYS_INVPARAMS (The parameter passed is invalid)
Pre Condition
Functions CSL_edma3Init(), CSL_edma3Open() must be called successfully in that order before CSL_edma3GetHwSetup() can be called.
Post Condition
The hardware setup structure is populated with the hardware setup parameters
