 *   @n@b CSL_mcbspHwSetupRaw
 *
 *   @b Description
 *   @n This function initializes the device registers with the register-values
 *      provided through the Config Data structure.
 *
 *   @b Arguments
 *   @verbatim
            hMcbsp        Handle to the Mcbsp instance

            config          Pointer to config structure
     @endverbatim
 *
 *   <b> Return Value </b>  CSL_Status
 *   @li                    CSL_SOK             - Configuration successful
 *   @li                    CSL_ESYS_BADHANDLE  - Invalid handle
 *   @li                    CSL_ESYS_INVPARAMS  - Configuration is not
 *                                                properly initialized
 *
 *   <b> Pre Condition </b>
 *   @n  None
 *
 *   <b> Post Condition </b>
 *   @n  The registers of the specified MCBSP instance will be setup
 *       according to value passed.
 *
 *   @b Modifies
 *   @n Hardware registers of the specified NAND instance.
