2020-01-23usb: phy: phy-gpio-vbus-usb: Convert to GPIO descriptorsLinus Walleij
Instead of using the legacy GPIO API and keeping track on polarity inversion semantics in the driver, switch to use GPIO descriptors for this driver and change all consumers in the process. This makes it possible to retire platform data completely: the only remaining platform data member was "wakeup" which was intended to make the vbus interrupt wakeup capable, but was not set by any users and thus remained unused. VBUS was not waking any devices up. Leave a comment about it so later developers using the platform can consider setting it to always enabled so plugging in USB wakes up the platform.

2017-11-04USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

2012-05-17USB: gpio_vbus: wakeup support on GPIO VBUS interruptsShinya Kuribayashi
We'd like to see the system waking up from the system-wide suspend when it gets plugged-in, or the USB cable is pulled out. Also makes it configurable via platform data 'wakeup'.

2009-01-07USB: otg: gpio_vbus transceiver stubPhilipp Zabel
gpio_vbus provides simple GPIO VBUS sensing for peripheral controllers with an internal transceiver. Optionally, a second GPIO can be used to control D+ pullup. It also interfaces with the regulator framework to limit charging currents when powered via USB. gpio_vbus requests the regulator supplying "vbus_draw" and can enable/disable it or limit its current depending on USB state.
