Ohh..I thought just writing "tested on STih407" is sufficient.
Anyway..Here is the detail:

1) Patches were created compile tested on your next branch ie 3.15-rc1.
2) They were tested with STih407, which has dwc3 controller as DRD. Since
STih407 kernel is still at 3.10.27, therefore patches at step1 was
applied to this kernel without any modification.
3) Please see analyzer snapshot showing host issuing LGO_U1 and device
acking it. I can run testusb from this host and can see device going
to low power mode several times while test is running.
