Use more compact of_property_read_bool() calls for the boolean properties
instead  of of_find_property() calls  in of_usb_host_tpl_support() and
of_usb_update_otg_caps().

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing

If usb/otg-fsm.h and usb/composite.h are included together
then it results in the build warning [1].

Prevent that by defining VDBG locally.

Also get rid of MPC_LOC which doesn't seem to be used
by anyone.

The modalias sysfs attr is lacking a newline for DT aliases on platform
devices. The macio and ibmebus correctly add the newline, but open code it.
Introduce a new function, of_device_modalias(), that fills the buffer with
the modalias including the newline and update users of the old
of_device_get_modalias function.

<title>usb: ulpi: Support device discovery via DT</title>

<id>ef6a7bcfb01c9c8df172ad06fb547216ca788711</id>
<content type='text'>
The qcom HSIC ULPI phy doesn't have any bits set in the vendor or
product ID registers. This makes it impossible to make a ULPI
driver match against the ID registers. Add support to discover
the ULPI phys via DT help alleviate this problem. In the DT case,
we'll look for a ULPI bus node underneath the device registering
the ULPI viewport (or the parent of that device to support
chipidea's device layout) and then match up the phy node
underneath that with the ULPI device that's created.

The side benefit of this is that we can use standard properties
in the phy node like clks, regulators, gpios, etc. because we
don't have firmware like ACPI to turn these things on for us. And
we can use the DT phy binding to point our phy consumer to the
phy provider.

The ULPI bus code supports native enumeration by reading the
vendor ID and product ID registers at device creation time, but
we can't be certain that those register reads will succeed if the
phy is not powered up. To avoid any problems with reading the ID
registers before the phy is powered we fallback to DT matching
when the ID reads fail.

If the ULPI spec had some generic power sequencing for these
registers we could put that into the ULPI bus layer and power up
the device before reading the ID registers. Unfortunately this
doesn't exist and the power sequence is usually device specific.
By having the device matched up with DT we can avoid this
problem.

usb: patches for v4.9 merge window

This time around we have 92 non-merge commits. Most
of the changes are in drivers/usb/gadget (40.3%)
with drivers/usb/gadget/function being the most
active directory (27.2%).

As for UDC drivers, only dwc3 (26.5%) and dwc2
(12.7%) have really been active.

The most important changes for dwc3 are better
support for scatterlist and, again, throughput
improvements. While on dwc2 got some minor stability
fixes related to soft reset and FIFO usage.

Felipe Tonello has done some good work fixing up our
f_midi gadget and Tal Shorer has implemented a nice
API change for our ULPI bus.

Apart from these, we have our usual set of
non-critical fixes, spelling fixes, build warning
fixes, etc.
