Adapted omap-usb3 PHY driver to Generic PHY Framework and moved phy-omap-usb3
driver in drivers/usb/phy to drivers/phy and also renamed the file to
phy-omap-pipe3 since this same driver will be used for SATA PHY and
PCIE PHY.
I would suggest to split the renaming and PHY adaptation into 2 separate patches.
Alright.

how about naming it to phy-ti-pipe3.c as it is used on OMAP as well as non-OMAP e.g. DRA7.
hmm.. I thought it would be consistent with other PHY drivers
(phy-omap-usb2). Moreover DRA7 is OMAP based platform ;-) Maybe we
should reserve that for later?
