Since usb5744 i2c initialization routine uses i2c SMBus APIs theseAPIs should only be invoked when kernel has I2C support.

usb: misc: onboard_hub: rename to onboard_devThis patch prepares onboad_hub to support non-hub devices by renamingthe driver files and their content, the headers and their references.The comments and descriptions have been slightly modified to keepcoherence and account for the specific cases that only affect onboardhubs (e.g. peer-hub).The "hub" variables in functions where "dev" (and similar names) variablesalready exist have been renamed to onboard_dev for clarity, which adds afew lines in cases where more than 80 characters are used.No new functionality has been added.Acked-by: Matthias Kaehlcke Signed-off-by: Javier Carrasco Link: https://lore.kernel.org/r/20240325-onboard_xvf3500-v8-2-29e3f9222922@wolfvision.netSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/misc/Kconfig

usb: Add support for Intel LJCA deviceImplements the USB part of Intel USB-I2C/GPIO/SPI adapter devicenamed "La Jolla Cove Adapter" (LJCA).The communication between the various LJCA module drivers and thehardware will be muxed/demuxed by this driver. Three modules (I2C, GPIO, and SPI) are supported currently.Each sub-module of LJCA device is identified by type field withinthe LJCA message header.The sub-modules of LJCA can use ljca_transfer() to issue a transferbetween host and hardware. And ljca_register_event_cb is exportedto LJCA sub-module drivers for hardware event subscription.The minimum code in ASL that covers this board isScope (\_SB.PCI0.DWC3.RHUB.HS01) { Device (GPIO) { Name (_ADR, Zero) Name (_STA, 0x0F) } Device (I2C) { Name (_ADR, One) Name (_STA, 0x0F) } Device (SPI) { Name (_ADR, 0x02) Name (_STA, 0x0F) } }Signed-off-by: Wentong Wu Reviewed-by: Sakari Ailus Reviewed-by: Andi Shyti Tested-by: Hans de Goede Reviewed-by: Oliver Neukum Link: https://lore.kernel.org/r/1696833205-16716-2-git-send-email-wentong.wu@intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/misc/Kconfig

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/misc/Kconfig

22683e48 - usb: misc: onboard_usb_hub: Drop obsolete dependency on COMPILE_TEST

Sun, 27 Nov 2022 14:52:30 +0000

usb: misc: onboard_usb_hub: Drop obsolete dependency on COMPILE_TESTSince commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), itis possible to test-build any driver which depends on OF on anyarchitecture by explicitly selecting OF. Therefore depending onCOMPILE_TEST as an alternative is no longer needed.It is actually better to always build such drivers with OF enabled,so that the test builds are closer to how each driver will actually bebuilt on its intended target. Building them without OF may not testmuch as the compiler will optimize out potentially large parts of thecode. In the worst case, this could even pop false positive warnings.Dropping COMPILE_TEST here improves the quality of our testing andavoids wasting time on non-existent issues.Cc: Matthias Kaehlcke Cc: Greg Kroah-Hartman Signed-off-by: Jean Delvare Link: https://lore.kernel.org/r/20221127155230.144886b7@endymion.delvareSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/misc/Kconfig

8bc06364 - usb: misc: Add onboard_usb_hub driver

Thu, 30 Jun 2022 19:35:29 +0000

usb: misc: Add onboard_usb_hub driverThe main issue this driver addresses is that a USB hub needs to bepowered before it can be discovered. For discrete onboard hubs (anexample for such a hub is the Realtek RTS5411) this is often solvedby supplying the hub with an 'always-on' regulator, which is kindof a hack. Some onboard hubs may require further initializationsteps, like changing the state of a GPIO or enabling a clock, whichrequires even more hacks. This driver creates a platform devicerepresenting the hub which performs the necessary initialization.Currently it only supports switching on a single regulator, supportfor multiple regulators or other actions can be added as needed.Different initialization sequences can be supported based on thecompatible string.Besides performing the initialization the driver can be configuredto power the hub off during system suspend. This can help to extendbattery life on battery powered devices which have no requirementsto keep the hub powered during suspend. The driver can also beconfigured to leave the hub powered when a wakeup capable USB deviceis connected when suspending, and power it off otherwise.Technically the driver consists of two drivers, the platform driverdescribed above and a very thin USB driver that subclasses thegeneric driver. The purpose of this driver is to provide the platformdriver with the USB devices corresponding to the hub(s) (a hubcontroller may provide multiple 'logical' hubs, e.g. one to supportUSB 2.0 and another for USB 3.x).Co-developed-by: Ravi Chandra Sadineni Reviewed-by: Douglas Anderson Signed-off-by: Ravi Chandra Sadineni Signed-off-by: Matthias Kaehlcke Link: https://lore.kernel.org/r/20220630123445.v24.3.I7c9a1f1d6ced41dd8310e8a03da666a32364e790@changeidSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/misc/Kconfig

517c4c44 - usb: Add driver to allow any GPIO to be used for 7211 USB signals

Mon, 12 Oct 2020 20:00:07 +0000

usb: Add driver to allow any GPIO to be used for 7211 USB signalsThe Broadcom 7211 has new functionality that allows some USB lowspeed side band signals, that go from the XHCI host controller topins on the chip, to be remapped to use any GPIO pin instead of thelimited set selectable by hardware. This can be done without changingthe standard driver for the host controller. There is currentlysupport for three USB signals, PWRON, VBUS_PRESENT and PWRFLT. Thisdriver will allow the remapping of any of these three signals basedon settings in the Device Tree node for the driver. The driver waswritten so that it could handle additional signals added in thefuture by just adding the correct properties to the DT node.Below is an example of a DT node that would remap all threesignals:usb_pinmap: usb-pinmap@22000d0 { compatible = "brcm,usb-pinmap"; reg = <0x22000d0 0x4>; in-gpios = <&gpio 18 0>, <&gpio 19 0>; brcm,in-functions = "VBUS", "PWRFLT"; brcm,in-masks = <0x8000 0x40000 0x10000 0x80000>; out-gpios = <&gpio 20 0>; brcm,out-functions = "PWRON"; brcm,out-masks = <0x20000 0x800000 0x400000 0x200000>; interrupts = <0x0 0xb2 0x4>;};Signed-off-by: Al Cooper Link: https://lore.kernel.org/r/20201012200007.8862-3-alcooperx@gmail.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/misc/Kconfig
