Turns out the ones I put in tegra20.dtsi are NOT the defaults. The defaults are in arch/arm/mach-tegra/usb_phy.c, contained in "utmip_defaults[]".

I think I'm going to put those utmip_defaults[] stuff into tegra20.dtsi, and override them in tegra-seaboard.dts. How's that sound?

And since there are defaults specified in tegra20.dtsi, does it really make sense to also have default values assigned in ehci-tegra.c (for when a property is not present)? I worry that the information is now duplicated. If those properties aren't present, then someone's mucked with the tegra20.dtsi ehci properties.
