I happen to have a *really old* patch addressing Tegra [1], which
I was never able to test (no HW). Rebasing it shouldn't be too hard,
and maybe you can find someone internally willing to give it a spin?

Sure, that helps a bunch, I will ask internally if someone in that BU
can take a look.

I just rebased[1] the patch onto -rc2, and provided a TODO list in the
commit message.

Thanks,

M.
