This can't be correct on Tegra20 since Tegra30 didn't exist at the time. You'll need to drop the first string in the list for this to be correct.
Also, might be worth copying these from the Linux kernel's copy of the device tree files, since they are slightly different. That might involve pulling in a couple of headers too, though, so might not be worth it.

Sent v2 of patch dropping tegra30 compatible string.

Pulling from Linux kernel's copy of these files is not something I am up for at the moment.
