I don't think this is a hack, except for the bug: That should only 
happen on Tegra124 not on all Tegra SoCs.

Do you intend all 3 patches in this series to be merged? You'd mentioned 
you didn't when asked about this for a previous version. I'm not sure if 
that's changed?

To merge, I'd need Thierry's ack on patch 2, and Thierry's, Peter's, 
Mikko's, and/or Tuomas's on this patch.
