[PATCH] usb: host: tegra remove include of <mach/iomap.h>

[PATCH] usb: host: tegra remove include of <mach/iomap.h>

[Stephen Warren]

From: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Almost nothing from this file is used, and the file will hopefully be
deleted soon. Copy the tiny portions that are used directly into
ehci-tegra.c. I believe that Venu Byravarasu is working on cleaning up
our USB driver, and those cleanups will remove the need for these
constants.

Greg, if this patch can get into 3.7 (it's late, I know) at a point before
wherever you branch off your USB tree for 3.8, then that would be great.
If not, may I please request this patch be merged into a separate branch/tag
that is merged into both the Tegra and USB trees for 3.8, since I will
probably have cleanup patches in the Tegra tree that depend on this change,
and Venu will likely be sending patches through the USB tree that will need
to be merged with this too.

I don't know how you want to do this, but this, and the other tegra
patch, are now in the usb-next branch of my usb.git tree.

I would recommend just cherry-picking the thing into your tree if you
want to do work on top of it, we can handle merge issues later on in
3.8-rc1.

thanks,

Aargh! Felipe has already applied the PHY patch to his branch. I believe
he was also going to apply the EHCI driver patch too.

Having this just be applied to a next branch rather than a topic branch
was exactly what I wanted to avoid; it's why I wrote the heads-up above...

If I just cherry-pick the change, then that will cause the same commit
to exist under different commit IDs in two different trees. Isn't that a
no-no? That's exactly why I wanted this in a topic branch so we could
both merge it rather than duplicating it.

That's ok, they will merge together just fine.

This is a 3 line patch, not a big deal either way if it's duplicated.  A
whole different branch isn't really needed, I'm not insane like the arm
development trees, I only have 2 branches :)
