Thanks for pointing this out. I folded this into your patch "ARM:
davinci: da8xx: move usb code to new file"[1] and in turn based it on
Petr's patch cleaning up the deprecated properties from the usb.c file.
I have pushed all my v4.7/* branches to my tree and the master branch
merges all of these in. I should be sending the first pull request to
ARM-SoC by tomorrow. Any testing feedback on master branch appreciated.
Regards,
Sekhar

Subject: [PATCH] ARM: davinci: da8xx: move usb code to new file
We will be adding more da8xx-specific code for phy and clocks, so it will
be better to have this in a separate file. This way we don't have a bunch
of #ifdefs for all of the da8xx stuff.
While at it, fix some checkpatch warnings coming from existing code.
