[SRU trusty] arm64 USB support not enabled for APM Mustang

[Craig Magina]

[Impact]
Currently USB is not enabled for arm64 platforms. The patches will enable USB for arm64 and for APM's Mustang platform.

[Test Case]
Insert a USB device into an APM Mustang based platform.

[Regression Risk]
This patch set enables USB for all arm64 platforms, but they have all been accepted by upstream and have been tested on a couple Mustang platforms.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

The patches submitted for this bug turned out to not be the complete picture. I have not hit any issues with these patches, but there are additional patches that have been discovered recently as well as some bug fixes that will need to be upstreamed around the dwc3 driver to completely enable USB on the mustang platform. The current patch set will not be changed, just additional patches will be added to the set.

[Brad Figg (brad-figg)]

What wasn't this identified before? Wasn't a test kernel put together with these same patches and tested on an APM Mustang?

[Craig Magina (craig.magina)]

Yes, and things seemed to work fine. However the same patch set caused issues with wily on mcdivitt due to changes around the need for CONFIG_DMA_CMA to be enabled. So, during investigations there, additional patches were discovered as well as a bug fix for the dwc3 driver. The current patches in trusty proposed don't break anything, they just aren't enough to get USB working completely on the mustang.
