78  * Normally the device works on HS or SS, to simplify fifo management,
79  * devide fifo into some 512B parts, use bitmap to manage it; And
80  * 128 bits size of bitmap is large enough, that means it can manage
81  * up to 64KB fifo size.
89  * Maximum size of ep0 response buffer for ch9 requests,
112  * @MU3D_EP0_STATE_STALL: ep0 is in stall status, will be auto-cleared
137  * @base: the base address of fifo
138  * @limit: the bitmap size in bits
139  * @bitmap: fifo bitmap in unit of @MTU3_EP_FIFO_UNIT
149  *	The format of TX GPD is a little different from RX one.
150  *	And the size of GPD is 16 bytes.
160  *	bit[23:16]: ([EL] bit[31:24]) extension address (TX ONLY),
167  *		(TX): the buffer length of the data to transmit
172  *	bit29: ([EL] abandoned) Zero Length Packet (ZLP) (TX ONLY)
187 * NOTE: the size of GPD ring should be >= 2
204 * @role_sw : use USB Role Switch to support dual-role switch, can't use
207 * @is_u3_drd: whether port0 supports usb3.0 dual-role device or not
208 * @manual_drd_enabled: it's true when supports dual-role device by debugfs
229  *		host only, device only or dual-role mode
232  * @u2p_dis_msk: mask of disabling usb2 ports, e.g. bit0==1 to
234  *		but when use dual-role mode, can't disable u2port0
237  * @dbgfs_root: only used when supports manual dual-role switch via debugfs
