Tue, 19 May 2026 02:07:31 +0200

usb: xhci-pci: add AMD Promontory 21 PCI glueAMD Promontory 21 (PROM21) xHCI PCI functions use the common xhci-pcicore for USB operation, but also expose controller-specific sensor data.Add a small PROM21 PCI glue driver for AMD 1022:43fc and 1022:43fdcontrollers.The glue delegates USB host operation to the common xhci-pci core andpublishes a "hwmon" auxiliary device with parent-provided MMIO data.Auxiliary device creation failure is logged but does not fail the xHCIprobe.Make the PROM21 glue a hidden Kconfig tristate driven by the user-visibleSENSORS_PROM21_XHCI option. If sensor support is disabled, genericxhci-pci binds PROM21 controllers normally. If sensor support is enabled,the glue follows USB_XHCI_PCI.This keeps the auxiliary device available for a modular sensor driver whileavoiding a built-in xhci-pci core handing PROM21 controllers to a gluedriver that is only available as a module during initramfs.Assisted-by: Codex:gpt-5.5Signed-off-by: Jihong Min Reviewed-by: Mario Limonciello (AMD) Tested-by: Yaroslav Isakov Acked-by: Guenter Roeck Link: https://patch.msgid.link/20260519000732.2334711-2-hurryman2212@gmail.comSigned-off-by: Greg Kroah-Hartman List of files: /linux/drivers/usb/host/Makefile

Wed, 09 Apr 2025 21:47:34 +0200

xhci: sideband: add initial api to register a secondary interrupter entityIntroduce XHCI sideband, which manages the USB endpoints being requested bya client driver. This is used for when client drivers are attempting tooffload USB endpoints to another entity for handling USB transfers. XHCIsec intr will allow for drivers to fetch the required information about thetransfer ring, so the user can submit transfers independently. Expose therequired APIs for drivers to register and request for a USB endpoint and tomanage XHCI secondary interrupters.Driver renaming, multiple ring segment page linking, proper endpoint cleanup, and allowing module compilation added by Wesley Cheng to completeoriginal concept code by Mathias Nyman.Tested-by: Puma Hsu Tested-by: Daehwan Jung Signed-off-by: Mathias Nyman Co-developed-by: Wesley Cheng Signed-off-by: Wesley Cheng Acked-by: Mark Brown Link: https://lore.kernel.org/r/20250409194804.3773260-2-quic_wcheng@quicinc.comSigned-off-by: Greg Kroah-Hartman List of files: /linux/drivers/usb/host/Makefile

usb: host: u132-hcd: Delete driverThis driver got its last actual change in 2006 and is probably unused asnowbody should use a cardbus to USB adapter any more.If it were still used, the driver was in urgent need for maintainerlove. (Explicit kref handling, underdocumented locking, .remove() canreturn errors ...)Also the link in the (now removed) help text doesn't look activelymaintained.

To untangle this, make the xhci-rcar.kodriver a standalone module that just calls into the xhci-plat.ko modulelike other drivers do.This allows handling the dependency on the USB_RZV2M_USB3DRD driver toonly affect the xhci-rcar module and simplify the xhci-plat module.It also allows leaving out the hacks for broken dma mask and nesteddevices from the rcar side and keep that only in the generic xhci driver.As a future cleanup, the marvell and dwc3 specific bits of xhci-plat.ccould be moved out as well, but that is not required for this bugfix.Fixes: c52c9acc415e ("xhci: host: Add Renesas RZ/V2M SoC support")Signed-off-by: Arnd Bergmann Tested-by: Biju Das Link: https://lore.kernel.org/r/20230131150531.12347-1-arnd@kernel.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux/drivers/usb/host/Makefile

Sun, 23 Oct 2022 16:47:06 +0200

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/drivers/usb/host/Makefile
