From mboxrd@z Thu Jan 1 00:00:00 1970 From: Juergen Kilb Subject: [PATCH] Fixed gpio polarity of gpio USB-phy reset. Date: Thu, 14 Apr 2011 09:31:43 +0200 Message-ID: <1302766303-1157-1-git-send-email-J.Kilb@phytec.de> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: linux-arm-kernel@lists.infradead.org Cc: dbrownell@users.sourceforge.net, balbi@ti.com, gregkh@suse.de, linux-usb@vger.kernel.org, linux-omap@vger.kernel.org, linux-kernel@vger.kernel.org, sameo@linux.intel.com, Juergen Kilb List-Id: linux-omap@vger.kernel.org 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.
