[PATCH v2 03/10] usb: dwc3: Enable runtime pm only after PHYs areinitialized

From: Vivek Gautam
Date: Sat Mar 02 2013 - 08:25:32 EST


Allow dwc3 to enable auto power management only after its PHYs
are initialized so that any further PHY handling by dwc3's
runtime power management callbacks is fine.
