this patch series is to add mx28 usb host function. the driver only support usb host mode on usb port1. the driver reuses ehci-mxc.c under usb/host, but did some modifications based on it to satisfy mx28 usb host requirement. The modifications will not affect other platforms. Code is based on the branch for-next in sascha's tree http://git.pengutronix.de/git/imx/linux-2.6.git Tested on MX28 EVK. changes since v1: * add dummy clock to avoid adding cpu judgement in driver for Sascha's request. * use context in phy functions, so that usb device could share the code. * some code consolidation and patch reorgnization. * error checking improvement. * remove a few unneccesary code.
