Oh, I find I lost many discussions using company email.

best one for all
i.mx SoCs, as both internal and upstream fsl code use it.

It discussed before:
http://marc.info/?l=linux-usb&m=129906859817430&w=2

I just wonder if ci13xxx_udc.c can support fsl's well as it has below
at comment.

/*
 * Description: MIPS USB IP core family device controller
 *              Currently it only supports IP part number CI13412
 */
I will check with IC guys to see if i.mx's controller is compatible
with CI13412.
If fsl's compatible with CI13412, then mxs can try to use ci13xxx_udc.c to see
if there are any problems, If no problems with kinds of testing,
we can switch all i.mx SoC to ci13xxx_udc.c.
