* usb: misc: onboard_usb_dev: introduce new config symbol for usb5744 SMBus ↵Radhey Shyam Pandey2024-10-041-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | support Introduce new kernel config symbol for Microchip usb5744 SMBus programming support. Since usb5744 i2c initialization routine uses i2c SMBus APIs these APIs should only be invoked when kernel has I2C support. This new kernel config describes the dependency on I2C kernel support and fix the below build issues when USB_ONBOARD_DEV=y and CONFIG_I2C=m. riscv64-linux-ld: drivers/usb/misc/onboard_usb_dev.o: undefined reference to `i2c_find_device_by_fwnode' drivers/usb/misc/onboard_usb_dev.c:408:(.text+0xb24): undefined reference to `i2c_smbus_write_block_data' <snip> Parsing of the i2c-bus bus handle is not put under usb5744 kernel config check as the intention is to report an error when DT is configured for usb5744 SMBus support and kernel has USB_ONBOARD_DEV_USB5744 disabled.

* usb: misc: onboard_hub: rename to onboard_devJavier Carrasco2024-03-271-8/+8
| | | | | | | | | | | | | | | | | | | | This patch prepares onboad_hub to support non-hub devices by renaming the driver files and their content, the headers and their references. The comments and descriptions have been slightly modified to keep coherence and account for the specific cases that only affect onboard hubs (e.g. peer-hub). The "hub" variables in functions where "dev" (and similar names) variables already exist have been renamed to onboard_dev for clarity, which adds a few lines in cases where more than 80 characters are used. No new functionality has been added.

* usb: Add support for Intel LJCA deviceWentong Wu2023-10-111-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implements the USB part of Intel USB-I2C/GPIO/SPI adapter device named "La Jolla Cove Adapter" (LJCA). The communication between the various LJCA module drivers and the hardware 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 within the LJCA message header. The sub-modules of LJCA can use ljca_transfer() to issue a transfer between host and hardware. And ljca_register_event_cb is exported to LJCA sub-module drivers for hardware event subscription. The minimum code in ASL that covers this board is Scope (\_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 <wentong.wu@intel.com> Reviewed-by: Sakari Ailus <sakari.ailus@linux.intel.com> Reviewed-by: Andi Shyti <andi.shyti@linux.intel.com> Tested-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Oliver Neukum <oneukum@suse.com> Link: https://lore.kernel.org/r/1696833205-16716-2-git-send-email-wentong.wu@intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* usb: move config USB_USS720 to usb's misc KconfigLukas Bulwahn2023-03-291-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | This driver didn't see real maintainance since several years. It has several trivial issues (check $(scripts/checkpatch.pl -f drivers/usb/misc/ftdi-elan.c)) and some harder ones (difficult locking, explict kref handling, ...).

| | | | | | | | | | | | | | | | | | | This driver got its last actual change in 2006 and is probably unused as nowbody should use a cardbus to USB adapter any more. If it were still used, the driver was in urgent need for maintainer love. (Explicit kref handling, underdocumented locking, .remove() can return errors ...) Also the link in the (now removed) help text doesn't look actively maintained. According to archive.org it forwarded to http://www.copenhagen-hotel.net/ already back in 2018. So don't waste more time on this driver and just delete it.

* usb: misc: onboard_usb_hub: Drop obsolete dependency on COMPILE_TESTJean Delvare2022-11-291-1/+1
| | | | | | | | | | | | | | | | | | | | | Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_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 be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

* usb: misc: Add onboard_usb_hub driverMatthias Kaehlcke2022-07-081-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main issue this driver addresses is that a USB hub needs to be powered before it can be discovered. For discrete onboard hubs (an example for such a hub is the Realtek RTS5411) this is often solved by supplying the hub with an 'always-on' regulator, which is kind of a hack. Some onboard hubs may require further initialization steps, like changing the state of a GPIO or enabling a clock, which requires even more hacks. This driver creates a platform device representing the hub which performs the necessary initialization. Currently it only supports switching on a single regulator, support for multiple regulators or other actions can be added as needed. Different initialization sequences can be supported based on the compatible string. Besides performing the initialization the driver can be configured to power the hub off during system suspend. This can help to extend battery life on battery powered devices which have no requirements to keep the hub powered during suspend. The driver can also be configured to leave the hub powered when a wakeup capable USB device is connected when suspending, and power it off otherwise. Technically the driver consists of two drivers, the platform driver described above and a very thin USB driver that subclasses the generic driver. The purpose of this driver is to provide the platform driver with the USB devices corresponding to the hub(s) (a hub controller may provide multiple 'logical' hubs, e.g. one to support USB 2.0 and another for USB 3.x).

* usb: Add driver to allow any GPIO to be used for 7211 USB signalsAl Cooper2020-10-281-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Broadcom 7211 has new functionality that allows some USB low speed side band signals, that go from the XHCI host controller to pins on the chip, to be remapped to use any GPIO pin instead of the limited set selectable by hardware. This can be done without changing the standard driver for the host controller. There is currently support for three USB signals, PWRON, VBUS_PRESENT and PWRFLT. This driver will allow the remapping of any of these three signals based on settings in the Device Tree node for the driver. The driver was written so that it could handle additional signals added in the future by just adding the correct properties to the DT node. Below is an example of a DT node that would remap all three signals: 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 <alcooperx@gmail.com> Link: https://lore.kernel.org/r/20201012200007.8862-3-alcooperx@gmail.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* / usb: Add driver for UCSIHeikki Krogerus2016-04-301-0/+26
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | USB Type-C Connector System Software Interface (UCSI) is specification that defines the registers and data structures that can be used to control USB Type-C ports on a system. UCSI is used on several Intel Broxton SoC based platforms. Things that UCSI can be used to control include at least USB Data Role swapping, Power Role swapping and controlling of Alternate Modes on top of providing general details about the port and the partners that are attached to it. The initial purpose of the UCSI driver is to make sure USB is in host mode on desktop and server systems that are USB dual role capable, and provide UCSI interface. The goal is to integrate the driver later to an USB Type-C framework for Linux kernel, and at the same time add support for more extensive USB Type-C port control that UCSI offers, for example data role swapping, power role swapping, Alternate Mode control etc. The UCSI specification is public can be obtained from here: http://www.intel.com/content/www/us/en/io/universal-serial-bus/usb-type-c-ucsi-spec.html Signed-off-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* USB: Add LVS Test device driverPratyush Anand2014-07-181-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OTG3 and EH Compliance Plan 1.0 talks about Super Speed OTG Verification system (SS-OVS) which consists of an excersizer and analyzer. USB Compliance Suite from Lecroy or Ellisys can act as such SS-OVS for Link Layer Validation (LVS). Some modifications are needed for an embedded Linux USB host to pass all these tests. Most of these tests require just Link to be in U0. They do not work with default Linux USB stack since, default stack does port reset and then starts sending setup packet, which is not expected by Link Layer Validation (LVS) device of Lecroy Compliance Suit. Then, There are many Link Layer Tests which need host to generate specific traffic. This patch supports specific traffic generation cases. As of now all the host Lecroy Link Layer-USBIF tests (except TD7.26) passes with this patch for single run using Lecroy USB Compliance Suite Version 1.98 Build 239 and Lecroy USB Protocol Analyzer version 4.80 Build 1603. Therefore patch seems to be a good candidate for inclusion. Further modification can be done on top of it. lvstest driver will not bind to any device by default. It can bind manually to a super speed USB host controller root hub. Therefore, regular hub driver must be unbound before this driver is bound. For example, if 2-0:1.0 is the xhci root hub, then execute following to unbind hub driver. echo 2-0:1.0 > /sys/bus/usb/drivers/hub/unbind Then write Linux Foundation's vendor ID which is used by root hubs and SS root hub's device ID into new_id file. Writing IDs into new_id file will also bind the lvs driver with any available SS root hub interfaces. echo "1D6B 3" > /sys/bus/usb/drivers/lvs/new_id Now connect LVS device with root hub port. Test case specific traffic can be generated as follows whenever needed: 1. To issue "Get Device descriptor" command for TD.7.06: echo > /sys/bus/usb/devices/2-0\:1.0/get_dev_desc 2. To set U1 timeout to 127 for TD.7.18 echo 127 > /sys/bus/usb/devices/2-0\:1.0/u1_timeout 3. To set U2 timeout to 0 for TD.7.18 echo 0 > /sys/bus/usb/devices/2-0\:1.0/u2_timeout 4. To issue "Hot Reset" for TD.7.29 echo > /sys/bus/usb/devices/2-0\:1.0/hot_reset 5. To issue "U3 Entry" for TD.7.35 echo > /sys/bus/usb/devices/2-0\:1.0/u3_entry 6.

* USB: ELAN: Remove useless "default M" linesPaul Bolle2014-02-111-1/+0
| | | | | | | | | | | | | The Kconfig entries for USB_U132_HCD and USB_FTDI_ELAN default to (uppercase) "M". But in Kconfig (lowercase) "m" is a magic symbol. "M" is an ordinary symbol. As "M" is never set these Kconfig symbols will also not be set by default. Since I'm not aware of a reason why these driver should be set by default, let's just drop these lines (that basically do nothing).
