75  * Normally the device works on HS or SS, to simplify fifo management,
76  * devide fifo into some 512B parts, use bitmap to manage it; And
77  * 128 bits size of bitmap is large enough, that means it can manage
78  * up to 64KB fifo size.
86  * Maximum size of ep0 response buffer for ch9 requests,
107  * @MU3D_EP0_STATE_STALL: ep0 is in stall status, will be auto-cleared
132  * @base: the base address of fifo
133  * @limit: the bitmap size in bits
134  * @bitmap: fifo bitmap in unit of @MTU3_EP_FIFO_UNIT
144  *	The format of TX GPD is a little different from RX one.
145  *	And the size of GPD is 16 bytes.
155  *	bit[23:16]: ([EL] bit[31:24]) extension address (TX ONLY),
162  *		(TX): the buffer length of the data to transmit
167  *	bit29: ([EL] abandoned) Zero Length Packet (ZLP) (TX ONLY)
182 * NOTE: the size of GPD ring should be >= 2
202 * @role_sw : use USB Role Switch to support dual-role switch, can't use
205 * @is_u3_drd: whether port0 supports usb3.0 dual-role device or not
206 * @manual_drd_enabled: it's true when supports dual-role device by debugfs
233  *		host only, device only or dual-role mode
238  * @dbgfs_root: only used when supports manual dual-role switch via debugfs
