Ok, back to this, I'd like to get both this series and Andrew's xhci-tegra
support to 4.2

I did similar changes to xhci-tegra.c as Roger did to xhci-pci.c and xhci-plat.c,
but I can't test them and would need both your eyes on this to make sure it looks ok.

Both series are in a tegra_otg_merge topic branch in:

git://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git tegra_otg_merge

It contains Andrews full xhci tegra support series, but If I understood correctly only
patch 9/9 (maybe 8/9 as well?) will actually go through the xhci tree.
Patch 1/9 is not needed with Roger's changes anymre

The changes are in the last patch, here:
https://git.kernel.org/cgit/linux/kernel/git/mnyman/xhci.git/commit/?h=tegra_otg_merge

and would be squashed together with patch 9/9.

Thanks
Mathias
