ulpi_read and ulpi_write are used to read/write registers via ULPI bus.
Code generates compilation warnings on 64-bit machines where pointer
is cast to u32.
This patch drops all but last 8 bits of register address.
It is possible, because addresses on ULPI bus are 6- or 8-bit.
It is not possible (according to ULPI 1.1 spec) to have more
than 8-bit addressing.
This patch should not cause regressions as all calls to
ulpi_read/write use either structure pointer (@ address 0) or integer
offsets cast to pointer - addresses requested are way below 8-bit range.

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.

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.

Allows for easy configuration of the VBUS indicator related ULPI
config bits.
Also move the external indicator setup from ulpi_set_vbus() to
the new function.

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 <[email protected]> for reviewing the
omap-ehci patches and suggesting this approach.

Extend the existing ulpi viewport framework
to pass the port number information for any ulpi
ops. Fix the usage of ulpi api's accordingly.

Clean a mixup between u32 and int as a return type
for functions returning error values.
Use int as it is native (and widely used) return type.

There is no benefit in using u8, so switch to unsigned to reduce the
binary image size (by 20 bytes).

Add partial ULPI specification implementation that should be enough to
interface the ULPI PHYs in the boot loader context.
Add a viewport implementation for Chipidea/ARC based controllers.
