* USB: phy: Remove redundant license textGreg Kroah-Hartman2017-11-0719-184/+1
| | | | | | | | | | | | | | | | | | Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

* USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman2017-11-0421-0/+21
| | | | | | | | | | | | | | | | | | | | | 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.

With only 51 non-merge commits, this was one of the smallest pull requests from the Gadget tree. Most of the changes are in the mtu3 driver which added support for 36-bit DMA, support for USB 3.1 and support for dual-role (along with some non-critical fixes). The dwc2 driver got a few improvements to how we handle gadget state tracking and also added support for STM32F7xx devices. Other than that, we just some minor non-critical fixes and improvements all over the place.

The hang occurred during the suspend of the USB PHY when the Tegra PHY driver attempted to disable the PHY clock. The problem is that before the Tegra PHY driver is suspended, the chipidea driver already disabled the PHY clock and when the Tegra PHY driver suspended, it could not read DEVLC register and caused the device to hang. The Tegra USB PHY driver is used by both the Tegra EHCI driver and now the chipidea UDC driver and so simply removing the disabling of the PHY clock from the USB PHY driver would not work for the Tegra EHCI driver. Fortunately, the status of the USB PHY clock can be read from the USB_SUSP_CTRL register and therefore, to workaround this issue, simply poll the register prior to disabling the clock in USB PHY driver to see if clock gating has already been initiated. Please note that it can take a few uS for the clock to disable and so simply reading this status register once on entry is not sufficient. Similarly when turning on the PHY clock, it is possible that the clock is already enabled or in the process of being enabled, and so check for this when enabling the PHY. Please note that no issues are seen with Tegra20 because it has a slightly different PHY to Tegra30/114/124.

The basic conception of the usb charger is that, when one usb charger is added or removed by reporting from the extcon device state change, the usb charger will report to power user to set the current limitation. Power user can register a notifiee on the usb phy by issuing usb_register_notifier() to get notified by charger status changes or charger current changes. we can notify what current to be drawn to power user according to different charger type, and now we have 2 methods to get charger type. One is get charger type from extcon subsystem, which also means the charger state changes. Another is we can get the charger type from USB controller detecting or PMIC detecting, and the charger state changes should be told by issuing usb_phy_set_charger_state().

* usb: phy: Introduce one extcon device into usb phyBaolin Wang2017-05-172-3/+60
| | | | | | | | | | | Usually usb phy need register one extcon device to get the connection notifications. It will remove some duplicate code if the extcon device is registered using common code instead of each phy driver having its own related extcon APIs. So we add one pointer of extcon device into usb phy structure, and some other helper functions to register extcon.

Apart from your expected set of non-critical fixes, and other miscellaneous items, we have most of the changes in dwc3 (52.5%) with all other UDCs following with 34.8%. As for the actual changes, the most important of them are all the recent changes to reduce memory footprint of dwc3, bare minimum dual-role support on dwc3 and reworked endpoint count and initialization routines.

* usb: phy: isp1301: Add OF device ID tableJavier Martinez Canillas2017-03-091-0/+7
| | | | | | | | | | | | | The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.
