Functions
static void	dwc_usb3_do_setup (volatile dwc_usb3_pcd_t *pcd)
	This routine processes SETUP commands. The USB Command processing is done in two places - the first being the PCD and the second being the Gadget driver (for example, the File-Backed Storage Gadget driver). More...
static void	ep0_do_stall (volatile dwc_usb3_pcd_t *pcd, int err_val)
	This routine stalls EP0. More...
static void	do_clear_halt (volatile dwc_usb3_pcd_t *pcd, volatile dwc_usb3_pcd_ep_t *ep)
	Clear the EP halt (STALL), and if there are pending requests start the transfer. More...
static void	do_get_status (volatile dwc_usb3_pcd_t *pcd)
	This routine processes the GET_STATUS Setup Commands. More...
static void	do_clear_feature (volatile dwc_usb3_pcd_t *pcd)
	This routine processes the CLEAR_FEATURE Setup Commands. More...
static void	do_set_feature (volatile dwc_usb3_pcd_t *pcd)
	This routine processes the SET_FEATURE Setup Commands. More...
static void	do_set_address (volatile dwc_usb3_pcd_t *pcd)
	This routine processes the SET_ADDRESS Setup Commands. More...
static void	do_get_descriptor (volatile dwc_usb3_pcd_t *pcd)
	This routine handles the Get Descriptor request for the BOS descriptor and the OTG descriptor, and passes all other requests to the Gadget driver. More...
static void	ep0_continue_transfer (volatile dwc_usb3_pcd_t *pcd, volatile dwc_usb3_pcd_req_t *req)
	This routine continues control IN transfers started by ep0_start_transfer, when the transfer does not fit in a single request. More...
static int	ep0_complete_request (volatile dwc_usb3_pcd_t *pcd, volatile dwc_usb3_pcd_req_t *req, dwc_usb3_dma_desc_t *desc, int status)
	This routine completes the ep0 control transfer. More...
static void	setup_in_status_phase (volatile dwc_usb3_pcd_t *pcd, void *buf, dwc_dma_t dma)
	This routine starts the Zero-Length Packet for the IN status phase of a control write transfer. More...
static void	setup_out_status_phase (volatile dwc_usb3_pcd_t *pcd, void *buf, dwc_dma_t dma)
	This routine starts the Zero-Length Packet for the OUT status phase of a control read transfer. More...
static void	dwc_usb3_handle_ep0 (volatile dwc_usb3_pcd_t *pcd, volatile dwc_usb3_pcd_req_t *req, u32 event)
	This routine handles EP0 Control transfers. More...
void	dwc_usb3_pcd_ep0_data_stage (volatile dwc_usb3_pcd_t *pcd, int length)
	This routine starts the data stage of a 3-stage control command. pcd->ep0state must be set to EP0_OUT_DATA_PHASE or EP0_IN_DATA_PHASE, and pcd->ep0->dwc_ep.is_in must be set to 0 or 1 before calling this routine. For IN, the data to be sent must be placed in pcd->ep0_status_buf before the call. More...
void	dwc_usb3_handle_ep0_xfer (volatile dwc_usb3_pcd_t *pcd, u32 event)
	This routine handles EP0 transfers. More...
