Hi Roland,

There is already a driver for the isp1301 otg part in the kernel, I don't
think we want to add another one.

>From what I can tell, this shares a common ancestry with the omap version
but has diverged quite a bit. The best solution would really be to
bring the two back together and let them share a common base driver,
with the lpc32xx and omap specific bits in another file.
