Hmm maybe check if current stable kernels work for you without
reverting anything ? Few weeks ago I did the the following two fixes
with cc stable v3.13+:

96be39ab34b7 usb: phy: twl4030-usb: Fix regressions to runtime PM on omaps
85601b8d81e2 usb: phy: twl4030-usb: Fix lost interrupts after ID pin goes down
