[PATCH v4 0/7] ARM: mx28: add usb host function

[Tony Lin]

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 add
platform irq handler routines if platform wants to
do something specific in irq handler.
the patch also consolidates some macro definitions
and structure definitions to make ehci-mxc.c better
reusable among mxs/mxc 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 v3:
 * change code to standard framework.
 * avoid changing pdata in driver.
 * pass testing usb0/usb1 on MX28 EVK board.

changes since v2:
 * add error condition clean up code.
 * remove unnecessary initial code.
 * change file name from regs-usbphy-mx28 to regs-usbphy-mxs.h.

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.
