I hate to say it ... but given that this will cause duplication of code, I'm somehow inclined to push you to do a complete replacement of the old musb code, remove it and add this. Tom, what do you think? > Ilya Yanok (5): > linux/usb/ch9.h: update with the version from Linux tree > musb-new: port of Linux musb gadget driver > musb-new: dsps backend driver > am33xx: init OTG hardware and new musb gadget driver > am335x_evm: enable musb gadget on port 0 Best regards, Marek Vasut _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
