From 5e6c86b017691230b6b47f19b7d5449997e8a0b8 Mon Sep 17 00:00:00 2001 From: Neil Zhang Date: Tue, 20 Dec 2011 13:20:21 +0800 Subject: [PATCH] usb: gadget: mv_udc: drop ARCH dependency This patch do the following things: 1. Change the Kconfig information. 2. Rename the driver name. 3. Don't do any type cast to io memory. 4. Add dummy stub for clk framework.
