Hello everyone, I'm working on a SoC which embeds an IP block from GDA Technologies labeled "Pravega USB3 SuperSpeed Controller" (data-sheet is v0.99r dated 2014-01-29). A cursory search returns: http://www.sourcing.co.jp/prod_ip.htm http://www.sourcing.co.jp/prod_ip/usb_host_pb.pdf In the compliance section, the data-sheet lists: - USB 3.0 Revision 1.0 and all associated ECNs - Inter-Chip Supplement to the USB Revision 3.0 Specification, Revision 1.02 - Backward compatible with USB2.0 Revision 2.0 and all associated ECNs - High Speed Inter Chip Specification, Rev 1.0 and associated ECNs - USB 2.0 Link Power Management Addendum and associated Erratas - xHCI specification version 1.0 (in host mode) My question is: should I be able to use the generic XHCI driver to drive this controller? I'd select USB_XHCI_HCD and USB_XHCI_PLATFORM, create the appropriate device tree node, and everything would auto-magically work? (The Makefile builds xhci-plat-hcd.o but I don't see xhci-plat-hcd.c Is it a generated file?) I'm confused though: if XHCI is standard, why are there different XHCI drivers for Mediatek, Marvell, Renesas, Tegra? Do they add additional features *on top of* the XHCI baseline? One more thing: AFAIU, the USB PHY is made by Synopsys. Do I need a driver for that too? (I should examine 7b8ef22ea547) Regards. -- 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
