I think 1st "tegra2" above should be changed to "nvidia".

Perhaps a more descriptive name could be used?  NV == non-volatile to me
at first glance, and if this is tegra2-specific maybe tegra2-common.h
would be more appropriate?

This define should match the name of the file.

The general policy is not to undef things unless its necessary.
Assuming CONFIG_USE_IRQ isn't defined elsewhere I'd remove the above
line.

The endif comment should be changed to match the define at the top of
the file.
