Hi Dmitry,

Usually, Greg could apply all USB patches, if I apply other USB related
patches, it may cause conflict with other patches in other's tree.
Greg, free feel to apply this series with 
Acked-by: Peter Chen <peter.chen@...nel.org>
for chipidea part.

For ARM defconfig patch, I think it should go ARM's tree.
