5b8031ccb4 Add more SPDX-License-Identifier tags
In a number of places we had wordings of the GPL (or LGPL in a few
cases) license text that were split in such a way that it wasn't caught
previously.  Convert all of these to the correct SPDX-License-Identifier
tag.

b0857c45c1 usb: omap: ulpi: fix ulpi transceiver access
This patch fix the omap access to the transceiver
configuration registers using the ulpi bus. As reported by
the documentation the bit31 is used only to check if the
transaction is done or still running and the reading and
writing operation have different offset and have different
values. What we need to do at the end of a transaction is
leave the bus in done state. Anyway an error using the ulpi
omap register is not recoverable so any error give out the
usage of this interface.

Tested on a custom OMAP5430 board with a TUSB1210 ULPI PHY
on USBB1.

928c4bdf9b usb: ulpi: Add omap-ulpi-view port support
Based on discussion from this thread [1].
Adding omap-view port that helps us in using the generic ulpi
framework for any ulpi phy ops using the INSNREG05_ULPI viewport
reg available on omap platform.

Currently ehci ports are available on omap3/4 platforms so enable the same
for beagle and panda, patch is tested on the same boards.

Thanks to Igor Grinberg <grinberg@compulab.co.il> for reviewing the
omap-ehci patches and suggesting this approach.
