The defaults are in the dt ehci node.  I'd really hate to duplicate these defaults in C code as well, if that's what you're suggesting (they're already duplicated privately elsewhere, sadly, in mach-tegra, but I'm hoping those defaults can go away once we move over to dt for good).  By failing probe if these defaults aren't present, I think it helps make sure the dt ehci node stays in sync with the code.

Or am I misunderstanding your comment?--
