These require firmware to be loaded and in case devices have ROM those can also be programmed if empty. If ROM is programmed, it runs from ROM as well. This includes patches from Christian which supported these controllers w/o ROM and later my patches for ROM support and debugfs hook for rom erase and export of xhci-pci functions. Changes in v8: Fix compile error reported by Kbuild-bot by making usb_hcd_pci_probe() take const struct hc_driver * as argument Changes in v7: Make a single module which removes issues with module loading Keep the renesas code in renesas file Add hc_driver as argument for usb_hcd_pci_probe and modify hdc drivers to pass this and not use driver_data Use driver data for fw name Remove code to check if we need to load firmware or not remove multiple fw version support, we can do that with symlink in userspace Changes in v6: Move the renesas code into a separate driver which invokes xhci-pci functions. Changes in v5: Added a debugfs rom erase patch, helps in debugging Squashed patch 1 & 2 as requested by Mathias Changes in v4: Rollback the delay values as we got device failures Changes in v3: Dropped patch 2 as discussed with Christian Removed aligned 8 bytes check Change order for firmware search from highest version to lowest Added entry for new firmware for device 0x14 as well Add tested by Christian Changes in v2: used macros for timeout count and delay removed renesas_fw_alive_check cleaned renesas_fw_callback removed recurion for renesas_fw_download added MODULE_FIRMWARE added comment for multiple fw order Christian Lamparter (1): usb: renesas-xhci: Add the renesas xhci driver Vinod Koul (4): usb: hci: add hc_driver as argument for usb_hcd_pci_probe usb: xhci: Add support for Renesas controller with memory usb: renesas-xhci: Add ROM loader for uPD720201 usb: xhci: provide a debugfs hook for erasing rom drivers/usb/core/hcd-pci.c | 7 +- drivers/usb/host/Makefile | 3 +- drivers/usb/host/ehci-pci.c | 6 +- drivers/usb/host/ohci-pci.c | 9 +- drivers/usb/host/uhci-pci.c | 8 +- drivers/usb/host/xhci-pci-renesas.c | 802 ++++++++++++++++++++++++++++ drivers/usb/host/xhci-pci.c | 43 +- drivers/usb/host/xhci-pci.h | 14 + include/linux/usb/hcd.h | 3 +- 9 files changed, 871 insertions(+), 24 deletions(-) create mode 100644 drivers/usb/host/xhci-pci-renesas.c create mode 100644 drivers/usb/host/xhci-pci.h -- 2.25.1
