While it would be physically possible for me to apply these patches now
and rely on Peter to add the clocks properties later, there's no point
in doing so, since as you say the drivers won't work with just these
patches. There will be less churn if we simply wait for the Tegra114
clock driver first, and then apply patches to add complete and working
DT nodes for all the devices.
