fb6f076d - USB: hub: Add Kconfig option to reduce number of port initialization retries

Mon, 28 Sep 2020 15:22:17 +0000

USB: hub: Add Kconfig option to reduce number of port initialization retriesDescription based on one by Yasushi Asano:According to 6.7.22 A-UUT “Device No Response” for connection timeoutof USB OTG and EH automated compliance plan v1.2, enumeration failurehas to be detected within 30 seconds. However, the old and newenumeration schemes each make a total of 12 attempts, and each attemptcan take 5 seconds to time out, so the PET test fails.This patch adds a new Kconfig option (CONFIG_USB_FEW_INIT_RETRIES);when the option is set all the initialization retry loops except theoutermost are reduced to a single iteration. This reduces the totalnumber of attempts to four, allowing Linux hosts to pass the PET test.The new option is disabled by default to preserve the existingbehavior. The reduced number of retries may fail to initialize a fewdevices that currently do work, but for the most part there should beno change. And in cases where the initialization does fail, it willfail much more quickly.Reported-and-tested-by: yasushi asano Signed-off-by: Alan Stern Link: https://lore.kernel.org/r/20200928152217.GB134701@rowland.harvard.eduSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/core/Kconfig

d991f855 - usb: remove redundant 'default n' from Kconfig-s

Mon, 20 May 2019 14:14:33 +0000

usb: remove redundant 'default n' from Kconfig-s'default n' is the default value for any bool or tristate Kconfigsetting so there is no need to write it explicitly.Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOOis not set' for visible symbols") the Kconfig behavior is the sameregardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/core/Kconfig

0f247626 - usb: core: Introduce a USB port LED trigger

Fri, 16 Sep 2016 14:13:48 +0000

usb: core: Introduce a USB port LED triggerThis commit adds a new trigger responsible for turning on LED when USBdevice gets connected to the selected USB port. This can can useful forvarious home routers that have USB port(s) and a proper LED telling usera device is connected.The trigger gets its documentation file but basically it just requiresenabling it and selecting USB ports (e.g. echo 1 > ports/usb1-1).There was a long discussion on design of this driver. Its current stateis a result of picking them most adjustable solution as others couldn'thandle all cases.1) It wasn't possible for the driver to register separated trigger for each USB port. Some physical USB ports are handled by more than one controller and so by more than one USB port. E.g. USB 2.0 physical port may be handled by OHCI's port and EHCI's port. It's also not possible to assign more than 1 trigger to a single LED and implementing such feature would be tricky due to syncing triggers and sysfs conflicts with old triggers.2) Another idea was to register trigger per USB hub. This wouldn't allow handling devices with multiple USB LEDs and controllers (hubs) controlling more than 1 physical port. It's common for hubs to have few ports and each may have its own LED.This final trigger is highly flexible. It allows selecting any USB portsfor any LED. It was also modified (comparing to the initial version) toallow choosing ports rather than having user /guess/ proper names. Itwas successfully tested on SmartRG SR400ac which has 3 USB LEDs,2 physical ports and 3 controllers.It was noted USB subsystem already has usb-gadget and usb-host triggersbut they are pretty trivial ones. They indicate activity only and can'thave ports specified.In future it may be good idea to consider adding activity support tousbport as well. This should allow switching to this more generic driverand maybe marking old ones as obsolete.This can be implemented with another sysfs file for setting mode. Thedefault mode wouldn't change so there won't be ABI breakage and so suchfeature can be safely implemented later.There was also an idea of supporting other devices (PCI, SDIO, etc.) butas this driver already contains some USB specific code (and will getmore) these should be probably separated drivers (triggers).Signed-off-by: Rafał Miłecki Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/core/Kconfig

289fcff4 - usb: add bus type for USB ULPI

Wed, 13 May 2015 12:26:42 +0000

usb: add bus type for USB ULPIUTMI+ Low Pin Interface (ULPI) is a commonly used PHYinterface for USB 2.0. The ULPI specification describes astandard set of registers which the vendors can extend fortheir specific needs. ULPI PHYs provide often functionssuch as charger detection and ADP sensing and probing.There are two major issues that the bus type is meant totackle:Firstly, ULPI registers are accessed from the controller.The bus provides convenient method for the controllerdrivers to share that access with the actual PHY drivers.Secondly, there are already platforms that assume ULPI PHYsare runtime detected, such as many Intel Baytrail basedplatforms. They do not provide any kind of hardwaredescription for the ULPI PHYs like separate ACPI deviceobject that could be used to enumerate a device from.Signed-off-by: Heikki Krogerus Acked-by: David Cohen Signed-off-by: Felipe Balbi List of files: /linux-6.15/drivers/usb/core/Kconfig
