From bf070bc14178f1458e7eccd76316ac24f76f1890 Mon Sep 17 00:00:00 2001 From: Grazvydas Ignotas Date: Wed, 21 Mar 2012 16:35:52 +0200 Subject: usb: musb: wake the device before ulpi transfers musb can be suspended at the time some other driver wants to do ulpi transfers using usb_phy_io_* functions, and that can cause data abort, as it happened with isp1704_charger: http://article.gmane.org/gmane.linux.kernel/1226122 Add pm_runtime to ulpi functions to rectify this. This also adds io_dev to usb_phy so that pm_runtime_* functions can be used.
