2017-11-07USB: phy: Remove redundant license textGreg Kroah-Hartman
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.

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.

2017-03-29usb: phy: isp1301: Fix build warning when CONFIG_OF is disabledJavier Martinez Canillas
Commit fd567653bdb9 ("usb: phy: isp1301: Add OF device ID table") added an OF device ID table, but used the of_match_ptr() macro that will lead to a build warning if CONFIG_OF symbol is disabled: drivers/usb/phy//phy-isp1301.c:36:34: warning: ‘isp1301_of_match’ defined but not used [-Wunused-const-variable=] static const struct of_device_id isp1301_of_match[] = { ^~~~~~~~~~~~~~~~ Fixes: fd567653bdb9 ("usb: phy: isp1301: Add OF device ID table") Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-03-09usb: phy: isp1301: Add OF device ID tableJavier Martinez Canillas
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.

2015-09-21usb: phy: isp1301: Export I2C module alias informationJavier Martinez Canillas
The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the device was registered using OF or platform code so So the driver needs to export the I2C table and this be built into the module or udev won't have the necessary information to auto load the module when the device is added.

2013-05-15usb: phy: Fix NULL pointer exception during usb_get_phyRobert Jarzmik
Upon initialisation (driver probe) a NULL pointer exception is triggered. This is due to lack of initialisation of device field in phy structure, which is used by phy framework in usb_get_phy(). Fix it by initialising the device field. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-03-18usb: phy: isp1301: implement PHY APIFelipe Balbi
this patch implements ->init() and ->set_vbus() methods for isp1301 transceiver driver. Later patches can now come in order to remove the hackery from ohci-nxp and lpc32xx udc drivers. Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-03-18usb: phy: isp1301: give it a context structureFelipe Balbi
this patch is a small preparation to fix isp1301 driver so that other platforms can use it. We're defining our private data structure to represent this device and adding the PHY to the PHY list. Later patches will come implementing proper PHY API and removing bogus code from ohci_nxp and lpc32xx_udc drivers. Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-03-18usb: phy: rename all phy drivers to phy-$name-usb.cFelipe Balbi
this will make sure that we have sensible names for all phy drivers. Current situation was already quite bad with too generic names being used. Signed-off-by: Felipe Balbi <balbi@ti.com>
