 *   @n@b CSL_gpioInit
 *
 *   @b Description
 *   @n This is the initialization function for the GPIO. This function is
 *      idempotent in that calling it many times is same as calling it once.
 *      This function initializes the CSL data structures, and doesn't affect
 *      the H/W.
 *
 *   @b Arguments
 *   @verbatim
 *          pContext   Context information for the instance. Should be NULL
 *   @endverbatim
 *
 *   <b> Return Value </b>  CSL_Status
 *   @li                    CSL_SOK - Always returns
 *
 *   <b> Pre Condition </b>
 *   @n  None
 *
 *   <b> Post Condition </b>
 *   @n  None
 *
 *   @b Modifies
 *   @n  None
 *
 *   @b Example
 *   @verbatim
 *    ...
 *    if (CSL_sysInit() == CSL_SOK) {
 *       CSL_gpioInit();
 *    }
 *   @endverbatim
