22  * To fix this problem, driver needs to make the first TRB in TD as invalid.
23  * After preparing all TRBs driver needs to check the position of DMA and
25  * then driver must defer making this TRB as valid. This TRB will be make
41  * driver prepares internal usb_request object and use it to arm DMA transfer.
245 		 * For stream capable endpoints driver use single correct TRB.
432  * driver try to detect whether endpoint need additional internal
474  * request queued by class driver.
491 		/* driver can't touch pending request */
592 			 * Intentionally driver returns positive value as
832 	 * zlp request is appended by driver, needn't call usb_gadget_giveback_request() to notify
833 	 * gadget composite driver.

1183 		 * To eliminate this strange behavioral driver set TRB_CHAIN
1717 		 * that host ignore the ERDY packet and driver has to send it
1746 		 * For isochronous transfer driver completes request on
1845 		 * from L1. To fix it, if any DMA transfer is pending driver

2041 		 * driver checks if it already has assigned enough buffers
2258  * This function set EP_CLAIMED flag which is added when the gadget driver
2260  * When the udc driver receives set_configurion request,
