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. > Sascha > > -- > Pengutronix e.K. | | > Industrial Linux Solutions | http://www.pengutronix.de/ | > Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | > Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | > -- > To unsubscribe from this list: send the line "unsubscribe linux-usb" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- BR, Peter Chen -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
