I also included the DRA7xx PCIe driver in my kernel so that pcie-designware-ep.c gets built. My only worry is that the code in pcie-designware-ep.c is not compile tested if DRA7xx is not selected (as it is the only driver using PCIE_DW_EP at the moment). -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
