usb: pci-quirks: handle HAS_IOPORT dependency for AMD quirk

2023-10-02T14:19:12+00:00

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends not being declared. In the pci-quirks case the I/O port acceses are used in the quirks for several AMD south bridges, Add a config option for the AMD quirks to depend on HAS_IOPORT and #ifdef the quirk code.

usb: move config USB_USS720 to usb's misc Kconfig

2023-03-29T08:34:08+00:00

The USS720 parport driver source code is in drivers/usb/misc/, the corresponding config is defined in drivers/usb/Kconfig. Some digging in the kernel's history revealed no good reason why it needs to be defined in USB's top-level Kconfig file, and why the config for the USS720 parport driver should be the first in the list of USB port drivers, while all other configs for drivers in drivers/usb/misc are in the USB Miscellaneous driver configuration file. Most probably, it was simply considered a bit more special when the USB Miscellaneous driver configuration file (drivers/usb/misc/Config.in back then) was initially created, and this config simply survived to remain at the top-level USB Kconfig file with all further code/Kconfig transformations and additions later on. Users rarely notice this config being at this position, as CONFIG_PARPORT (Parallel port support) needs to be enabled and only few users enable that. Nowadays, this USB_USS720 driver is probably not that special that it needs to be listed as first item of the USB port drivers. Move the configuration of the USS720 parport driver to the top of the USB Miscellaneous drivers section, as the configurations does not have a lot of specific ordering USB Miscellaneous drivers. This way, the USS720 parport driver is moved to the comment "USB Miscellaneous drivers", fitting to the driver's source code location, but still is at the top of the list for those few acquainted users of Kconfig UIs that might be looking for the config that was once at the top of the list of the USB port drivers. Put this config definition to a more local place. No semantic change.

usb: fotg210: Collect pieces of dual mode controller

2022-11-09T11:38:09+00:00

The Faraday FOTG210 is a dual-mode OTG USB controller that can act as host, peripheral or both. To be able to probe from one hardware description and to follow the pattern of other dual- mode controllers such as MUSB or MTU3 we need to collect the two, currently completely separate drivers in the same directory. After this, users need to select the main symbol USB_FOTG210 and then each respective subdriver. We pave the road to compile both drivers into the same kernel and select the one we want to use at probe() time, and possibly add OTG support in the end. This patch doesn't do much more than create the new symbol and collect the drivers in one place. We also add a comment for the section of dual-mode controllers in the Kconfig file so people can see what these selections are about. Also add myself as maintainer as there has been little response on my patches to these drivers.

usb: remove reference to deleted config STB03xxx

Commit 7583b63c343c ("powerpc/40x: Remove STB03xxx") removes the config STB03xxx, but left a reference in ./drivers/usb/Kconfig behind. Hence, ./scripts/checkkconfigsymbols.py warns: STB03xxx Referencing files: drivers/usb/Kconfig Remove this reference to the deleted config.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

usb: cdns3: Add Cadence USB3 DRD Driver

2019-08-29T07:57:04+00:00

This patch introduce new Cadence USBSS DRD driver to Linux kernel. The Cadence USBSS DRD Controller is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI)configurations. The current driver has been validated with FPGA platform. We have support for PCIe bus, which is used on FPGA prototyping. The host side of USBSS-DRD controller is compliant with XHCI specification, so it works with standard XHCI Linux driver. Signed-off-by: Pawel Laszczak Signed-off-by: Felipe Balbi

USB: Move wusbcore and UWB to staging as it is obsolete

2019-08-08T05:52:01+00:00

The UWB and wusbcore code is long obsolete, so let us just move the code out of the real part of the kernel and into the drivers/staging/ location with plans to remove it entirely in a few releases. Link: https://lore.kernel.org/r/20190806101509.GA11280@kroah.com Signed-off-by: Greg Kroah-Hartman
