Subject: [PATCH v13 0/5] usb: xhci: Add support for Renesas USB controllers
Date: Wed, 6 May 2020 11:30:20 +0530 [thread overview]
Message-ID: <20200506060025.1535960-1-vkoul@kernel.org> (raw)
This series add support for Renesas USB controllers uPD720201 and uPD720202.
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 v13:
- Make rensesas as independent module invoke by xhci-pci which can be
selected by users of such hardware
Changes in v12:
- Restore back module name for xhci-pci, so now renesas is a separate
module, export init/exit routines from renesas modules
- Update changelog on patch2
Changes in v11:
- update xhci->quirks and use that in remove function
- remove error return renesas_verify_fw_version()
- remove renesas_download_rom() and modify renesas_fw_download_image() for
reuse
Changes in v10:
remove renesas_xhci_pci_probe and call renesas_xhci_check_request_fw and
also cleanup exit code along with it.
Changes in v9:
Make fw load a sync call and have single instance of probe execute,
elimating probe/remove races
Add quirk for renesas and use that for loading
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 multip
