* staging: greybus: Remove redundant license textGreg Kroah-Hartman2017-11-111-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | Now that the SPDX tag is in all greybus 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.

* staging: greybus: add SPDX identifiers to all greybus driver filesGreg Kroah-Hartman2017-11-111-0/+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/staging/greybus files 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.

| | | | | | | | | | | The hc_driver structure is only passed as the first argument to usb_create_hcd, which is declared as const. Thus the hc_driver structure itself can be const.

* greybus: gbphy: Remove protocol specific version handlingViresh Kumar2016-05-311-4/+0
| | | | | | | | | | | | | | | | | We should be using the generic version handling at bundle level, instead of at protocol level for bridged PHY devices as well. The bundle version handling is already in place, though it is *not* used today as we haven't bumped the version of control protocol yet. Remove protocol specific handling for bridged PHY devices. Tested on EVT 1.5 with gpbridge-test module. No nuttx changes are required with this.

* greybus: gpbridge: rename 'gpbridge' to 'gbphy' everywhereSandeep Patil2016-05-191-19/+19
| | | | | | | | | | | | | | The 'gpbridge' name didn't relaly reflect what the bus is; which is a bus for bridged-phy devices. So, rename all instances of 'gpbridge' to more appropriate 'gbphy' Testing Done: Build and boot tested. 'lsgb' will stop displaying 'GPBridge' devices until I change the library to reflect this change.

But there is no reason to keep the "-gb" suffix in the second case. Remove the unnecessary suffix.
