2018-07-05usb: chipidea: Always build ULPI codeFabio Estevam1-0/+3
Commit 03e6275ae381 ("usb: chipidea: Fix ULPI on imx51") causes a kernel hang on imx51 systems that use the ULPI interface and do not select the CONFIG_USB_CHIPIDEA_ULPI option. In order to avoid such potential misuse, let's always build the chipidea ULPI code into the final ci_hdrc object. Tested on a imx51-babbage board.

2017-11-07USB: chipidea: Remove redundant license textGreg Kroah-Hartman1-9/+0
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-Hartman1-0/+1
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.

2017-01-20usb: chipidea: Add support for ULPI PHY busStephen Boyd1-0/+113
Some phys for the chipidea controller are controlled via the ULPI viewport. Add support for the ULPI bus so that these sorts of phys can be probed and read/written automatically without having to duplicate the viewport logic in each phy driver.
