d629c0e2 - usb: move config USB_USS720 to usb's misc Kconfig

Wed, 29 Mar 2023 07:51:25 +0000

usb: move config USB_USS720 to usb's misc KconfigThe USS720 parport driver source code is in drivers/usb/misc/, thecorresponding config is defined in drivers/usb/Kconfig. Some digging in thekernel's history revealed no good reason why it needs to be defined inUSB's top-level Kconfig file, and why the config for the USS720 parportdriver should be the first in the list of USB port drivers, while all otherconfigs for drivers in drivers/usb/misc are in the USB Miscellaneous driverconfiguration file.Most probably, it was simply considered a bit more special when the USBMiscellaneous driver configuration file (drivers/usb/misc/Config.in backthen) was initially created, and this config simply survived to remain atthe top-level USB Kconfig file with all further code/Kconfigtransformations and additions later on. Users rarely notice this configbeing at this position, as CONFIG_PARPORT (Parallel port support) needs tobe enabled and only few users enable that. Nowadays, this USB_USS720 driveris probably not that special that it needs to be listed as first item ofthe USB port drivers.Move the configuration of the USS720 parport driver to the top of the USBMiscellaneous drivers section, as the configurations does not have a lot ofspecific ordering USB Miscellaneous drivers. This way, the USS720 parportdriver is moved to the comment "USB Miscellaneous drivers", fitting to thedriver's source code location, but still is at the top of the list forthose few acquainted users of Kconfig UIs that might be looking for theconfig 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.Signed-off-by: Lukas Bulwahn Link: https://lore.kernel.org/r/20230329075125.32352-1-lukas.bulwahn@gmail.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/Kconfig

1dd33a9f - usb: fotg210: Collect pieces of dual mode controller

Sun, 23 Oct 2022 14:47:06 +0000

usb: fotg210: Collect pieces of dual mode controllerThe Faraday FOTG210 is a dual-mode OTG USB controller that canact as host, peripheral or both. To be able to probe from onehardware description and to follow the pattern of other dual-mode controllers such as MUSB or MTU3 we need to collect thetwo, currently completely separate drivers in the samedirectory.After this, users need to select the main symbol USB_FOTG210and then each respective subdriver. We pave the road tocompile both drivers into the same kernel and select theone we want to use at probe() time, and possibly add OTGsupport in the end.This patch doesn't do much more than create the new symboland collect the drivers in one place. We also add a commentfor the section of dual-mode controllers in the Kconfigfile so people can see what these selections are about.Also add myself as maintainer as there has been littleresponse on my patches to these drivers.Cc: Fabian Vogt Cc: Yuan-Hsin Chen Cc: Felipe Balbi Signed-off-by: Linus Walleij Link: https://lore.kernel.org/r/20221023144708.3596563-1-linus.walleij@linaro.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/Kconfig

USB: use genalloc for USB HCs with local memoryFor HCs that have local memory, replace the current DMA API usage witha genalloc generic allocator to manage the mappings for these devices.To help users, introduce a new HCD API, usb_hcd_setup_local_mem() thatwill setup up the genalloc backing up the device local memory. It willbe used in subsequent patches. This is in preparation for droppingthe existing "coherent" dma mem declaration APIs.

usb: roles: Add Intel xHCI USB role switch driverVarious Intel SoCs (Cherry Trail, Broxton and others) have an internal USBrole switch for swiching the OTG USB data lines between the xHCI hostcontroller and the dwc3 gadget controller.Note on some Cherry Trail systems there is ACPI/AML code listening toedge interrupts on the id-pin (through an _AIE ACPI method) and switchingthe role between ROLE_HOST and ROLE_NONE based on the id-pin. Note it doesnot set the role to ROLE_DEVICE, because device-mode is usually not usedunder Windows.The presence of AML code which modifies the cfg0 reg (on some systems)means that our read/write/modify of cfg0 may race with the AML codedoing the same to avoid this we take the global ACPI lock while doingthe read/write/modify.Signed-off-by: Hans de Goede Reviewed-by: Andy Shevchenko Signed-off-by: Heikki Krogerus Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/Kconfig

fde0aa6c - usb: common: Small class for USB role switches

Tue, 20 Mar 2018 12:57:04 +0000

usb: common: Small class for USB role switchesUSB role switch is a device that can be used to choose thedata role for USB connector. With dual-role capable USBcontrollers, the controller itself will be the switch, buton some platforms the USB host and device controllers areseparate IPs and there is a mux between them and theconnector. On those platforms the mux driver will need toregister the switch.With USB Type-C connectors, the host-to-device relationshipis negotiated over the Configuration Channel (CC). Thatmeans the USB Type-C drivers need to be in control of therole switch. The class provides a simple API for the USBType-C drivers for the control.For other types of USB connectors (mainly microAB) the classprovides user space control via sysfs attribute file thatcan be used to request role swapping from the switch.Reviewed-by: Hans de Goede Reviewed-by: Andy Shevchenko Signed-off-by: Heikki Krogerus Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/Kconfig
