From 557f447f21621de9c5447c8702c33b53279822ce Mon Sep 17 00:00:00 2001 From: Juergen Kilb Date: Thu, 14 Apr 2011 09:31:43 +0200 Subject: mfd: Fixed gpio polarity of omap-usb gpio USB-phy reset With commit 19403165 a main part of ehci-omap.c moved to drivers/mfd/omap-usb-host.c created by commit 17cdd29d. Due to this reorganisation the polarity used to reset the external USB phy changed and USB host doesn't recognize any devices.
