[PATCH 3.14 178/238] usb: dwc3: core: fix ordering for PHY suspend

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Felipe Balbi <balbi@xxxxxx>

commit dc99f16f076559235c92d3eb66d03d1310faea08 upstream.

We can't suspend the PHYs before dwc3_core_exit_mode()
has been called, that's because the host and/or device
sides might still need to communicate with the far end
link partner.

Fixes: 8ba007a (usb: dwc3: core: enable the USB2 and USB3 phy in probe)
Suggested-by: Alan Stern <stern@xxxxxxxxxxxxxxxxxxx>
